JP026821UNL 10 100 Base TX RJ45 MagJack Connector

ElecSuppliers Part Number GuideAug 27, 2026

JP026821UNL is a Pulse Electronics 1 port RJ45 MagJack connector designed for 10/100 Base TX Ethernet applications. It combines the RJ45 interface with integrated Ethernet magnetics in a compact through hole package and includes integrated green and orange yellow LED indicators.

The JP026821UNL configuration uses a 1X1 port arrangement, 90 degree right angle mounting, upward tab orientation and shielded construction with EMI fingers. These characteristics make it a specific Ethernet connector solution for PCB designs that require a single 10/100 Base TX network interface.

JP026821UNL Product Overview

JP026821UNL belongs to the PULSEJACK JP series of integrated Ethernet connectors.

The component provides one RJ45 port for 10/100 Base TX Ethernet and combines the connector interface with the magnetic components required by the Ethernet physical interface.

Its through hole construction provides a mechanically secure PCB connection, while the right angle orientation allows the RJ45 port to extend toward the edge of the equipment enclosure.

The integrated LEDs provide visual indication directly at the Ethernet port, making the component suitable for equipment where network status needs to be visible to the user.

JP026821UNL 10 100 Base TX Ethernet

The primary application of JP026821UNL is 10/100 Base TX Ethernet.

This allows the component to be used in Ethernet equipment operating at 10 Mbps or 100 Mbps.

The integrated magnetic interface is designed specifically around the Ethernet physical connection, allowing the connector assembly to occupy the role of both network receptacle and magnetic interface on the PCB.

For a product designed around Fast Ethernet, this makes JP026821UNL a more complete interface solution than a basic RJ45 connector without integrated magnetics.

JP026821UNL RJ45 Connector

JP026821UNL uses a standard 1 port RJ45 connector.

The single port configuration is suitable for products that require one wired Ethernet connection rather than a multi-port network interface.

The RJ45 interface provides the external connection between the PCB and an Ethernet cable, while the integrated magnetic section handles the electrical interface between the cable side and the Ethernet circuitry.

This combination helps keep the complete Ethernet port within one component footprint.

JP026821UNL Integrated Magnetics

Integrated magnetics are a defining feature of JP026821UNL.

An Ethernet interface normally requires magnetic coupling between the PHY circuitry and the cable interface. JP026821UNL incorporates this magnetic function into the connector assembly.

This can simplify PCB design because the Ethernet connector and magnetic interface do not need to be implemented as completely separate components.

For compact networking equipment, integrating these functions can also make the physical layout around the Ethernet port cleaner and easier to manage.

JP026821UNL 1X1 Port Configuration

JP026821UNL is a 1X1 Ethernet connector.

The 1X1 configuration provides one RJ45 port in a single horizontal position.

This arrangement is useful for embedded systems, controllers and networking equipment where only one Ethernet connection is required.

The single port design also gives the PCB designer flexibility when positioning the connector along an enclosure wall or PCB edge.

JP026821UNL Right Angle Mounting

JP026821UNL uses a 90 degree right angle configuration.

The right angle structure allows the RJ45 cable to enter from the side of the PCB.

This is particularly useful for products where the Ethernet port needs to be accessible from the rear or side panel of an enclosure.

The mechanical position of the connector should be considered together with the enclosure opening because the connector height and port position directly affect the final product design.

JP026821UNL Through Hole Package

JP026821UNL uses through hole PCB mounting with solder termination.

Through hole mounting provides mechanical reinforcement for a connector that may experience repeated insertion and removal forces from Ethernet cables.

The mounting structure is therefore important not only for electrical connection but also for the mechanical stability of the Ethernet interface.

When designing a replacement PCB footprint, the original JP026821UNL mounting dimensions should be checked carefully.

JP026821UNL Upward Tab Configuration

The RJ45 tab direction of JP026821UNL is upward.

This mechanical characteristic should not be overlooked when selecting an alternative connector.

Two RJ45 connectors may have the same number of ports and similar electrical functions while using different tab orientations.

A different tab direction can affect the mating mechanism and the available space around the connector.

For an existing product, the complete mechanical configuration should therefore be matched rather than selecting an RJ45 connector based only on the electrical specification.

JP026821UNL LED Indicators

JP026821UNL includes green and orange yellow LED indicators.

Integrated LEDs allow the Ethernet port to provide visual information without requiring separate LEDs to be installed elsewhere on the PCB.

This is useful for network equipment where users need to see the status of the Ethernet connection directly at the RJ45 port.

The integrated indicator arrangement can also reduce the number of separate front panel components required by the product design.

JP026821UNL Shielded Construction

JP026821UNL features a shielded construction with EMI fingers.

Ethernet connectors are located at the boundary between the internal PCB and an external cable, making electromagnetic compatibility an important design consideration.

The metal shielding structure provides a defined conductive enclosure around the connector area.

The actual EMC performance of the finished product still depends on the PCB grounding strategy, shield connection, enclosure and Ethernet circuit design.

The connector should therefore be treated as one part of the complete EMC solution.

JP026821UNL Five Core Magnetic Structure

JP026821UNL is specified with five cores per jack.

The integrated magnetic structure is designed around the requirements of the Ethernet interface.

This is one of the reasons that the exact part number matters when sourcing the connector. A visually similar RJ45 connector can have a different internal magnetic configuration and therefore may not provide equivalent electrical performance.

For a production design, the complete JP026821UNL configuration should be maintained when replacing or sourcing the component.

JP026821UNL Board Height

The height above the PCB is approximately 13.97 mm.

This dimension is important for the mechanical design of equipment using JP026821UNL.

The board height determines the relative position of the RJ45 opening and the enclosure panel.

When JP026821UNL is being used as a replacement for another MagJack, even a small dimensional difference can affect the alignment between the PCB and the enclosure.

Mechanical drawings should therefore be checked before approving a replacement.

JP026821UNL Contact Construction

The connector uses phosphor bronze contacts with gold plating.

The contact system is designed to provide the electrical connection between the mating RJ45 plug and the connector.

The plating and contact material are important when considering repeated mating cycles and long term electrical performance.

The connector is also designed around standard RJ45 mechanical requirements, making it suitable for common Ethernet cable interfaces.

JP026821UNL Operating Temperature

JP026821UNL is specified for an operating temperature range of approximately 0°C to +70°C.

This range is suitable for many commercial and indoor electronic systems.

For equipment installed in industrial environments, designers should compare the actual operating temperature of the enclosure with this range.

If the product must operate below 0°C or above +70°C, an alternative MagJack with a wider temperature specification may need to be considered.

JP026821UNL Ethernet Equipment Applications

JP026821UNL can be used in equipment requiring a single 10/100 Base TX Ethernet connection.

Potential applications include embedded controllers, communication equipment, industrial control boards, networking devices, LAN interfaces and other electronic products with a Fast Ethernet port.

Its integrated magnetics and LED indicators make it especially suitable for products where the Ethernet interface needs to remain compact and integrated.

JP026821UNL LAN Interface Applications

For a PCB with one Ethernet LAN interface, JP026821UNL provides the connector and magnetic interface in a single component.

This can reduce the amount of board space dedicated to separate Ethernet magnetic components.

The right angle construction is also useful when the Ethernet port needs to align with an external equipment panel.

For compact embedded products, the combination of 1X1 configuration, integrated magnetics and through hole mounting can simplify the mechanical and electrical interface design.

JP026821UNL PCB Design Considerations

PCB designers using JP026821UNL should consider the connector's mechanical and electrical characteristics together.

The through hole mounting points must match the connector footprint.

The Ethernet signal routing should follow the requirements of the selected PHY and magnetic interface.

The shield connection should be integrated into the overall EMC strategy.

The RJ45 port must also align correctly with the equipment enclosure.

Because JP026821UNL combines several functions in one component, changing to another connector without checking the complete footprint can create both electrical and mechanical compatibility problems.

JP026821UNL Replacement

When searching for a JP026821UNL replacement, the replacement should match more than the basic RJ45 interface.

The important characteristics include 10/100 Base TX operation, one port, integrated magnetics, right angle mounting, through hole termination, upward tab orientation, integrated LEDs and shielded construction.

The board height should also be checked because JP026821UNL is approximately 13.97 mm above the PCB.

A replacement with a different height or port position may not align with the original enclosure.

JP026821UNL Alternative

A suitable JP026821UNL alternative should reproduce the functions required by the original design.

If the PCB requires integrated Ethernet magnetics, a standard RJ45 receptacle without magnetics is not an equivalent alternative.

If the product requires integrated LEDs, an alternative without LEDs would also require additional components.

If the existing PCB uses through hole mounting, a surface mount alternative would require a different board design.

For this reason, alternative selection should begin with the complete JP026821UNL mechanical and electrical configuration.

JP026821UNL Obsolescence Consideration

The lifecycle status of JP026821UNL should be checked carefully when planning a new production design or long term replacement strategy.

For an existing product, buyers may still need JP026821UNL for repair, maintenance or continuation of an established PCB design.

For a new design, engineers should consider long term availability before committing to the part.

If the original JP026821UNL is difficult to source, an alternative MagJack should be evaluated against the original footprint, electrical characteristics, LED configuration and mechanical dimensions rather than selected solely by the RJ45 interface.

JP026821UNL Supplier Search

Buyers searching for JP026821UNL suppliers should use the complete manufacturer part number.

Searching only for 10/100 RJ45 MagJack can return a large number of visually similar components with different magnetic configurations, dimensions and LED arrangements.

The main points to check include the 1X1 port structure, 10/100 Base TX application, integrated magnetics, right angle orientation, through hole mounting, upward tab direction, LED colors and shield configuration.

For an existing PCB, the mechanical footprint should be compared before purchasing a replacement or alternative.

For production procurement, quantity, packaging, availability and delivery requirements should also be confirmed.

JP026821UNL Product Identification

The complete part number JP026821UNL should be used in the BOM, purchasing documentation and supplier inquiries.

This is particularly important because the PULSEJACK JP series contains multiple connector configurations that may look similar while having different electrical or mechanical characteristics.

The exact suffix should not be removed when searching for the component.

Using the complete MPN provides a much more precise way to identify the intended Ethernet connector.
