ElecSuppliers Part Number GuideAug 27, 2026

HDR-EA26LFYPG1+ is a Hirose 26 position board to board connector designed for PCB interconnection in compact electronic equipment. The complete part number identifies a specific configuration in the Hirose HDR connector family, so the full HDR-EA26LFYPG1+ designation should be retained when selecting, purchasing or replacing the component.

The connector is intended to provide a concentrated multi-contact interface between circuit boards. Its 26 position configuration makes it suitable for applications where multiple electrical connections need to be integrated into a compact board level connector.

HDR-EA26LFYPG1+ Product Overview

HDR-EA26LFYPG1+ is part of the Hirose Electric HDR series of board interconnection products.

Instead of using individual wires or multiple separate terminals, the connector provides a single structured interface containing 26 contacts.

This approach is useful in electronic equipment with modular PCB construction. One board can connect to another through a dedicated mating interface while keeping the internal wiring arrangement organized.

For engineering and purchasing purposes, the complete MPN is important because other HDR connectors can have similar appearances while differing in position count, pitch, mating configuration or mechanical dimensions.

HDR-EA26LFYPG1+ 26 Position Connector

The defining feature of HDR-EA26LFYPG1+ is its 26 position contact configuration.

Twenty six contacts allow multiple signals or other electrical connections to pass through one compact connector interface.

The actual pin assignment depends on the application and PCB design. Engineers should follow the appropriate connector documentation when assigning individual contacts.

The 26 position configuration is particularly useful for PCB assemblies that need more connections than a small single row connector can provide while still maintaining a compact interconnection structure.

HDR-EA26LFYPG1+ Board to Board Connection

HDR-EA26LFYPG1+ is designed for board to board interconnection.

Board to board connectors provide a controlled electrical and mechanical interface between two PCBs.

This can be valuable in modular equipment where the main board, interface board, control board or expansion board needs to be connected without using a cable harness.

The connector also helps establish a repeatable mating interface, which can simplify equipment assembly and maintenance.

HDR-EA26LFYPG1+ Hirose HDR Series

The Hirose HDR series includes multiple connector configurations intended for PCB interconnection.

For this reason, searching only for a generic 26 position Hirose connector may not identify the exact product required by an existing design.

The complete HDR-EA26LFYPG1+ part number should be used when searching for the component.

This is particularly important for replacement projects where the mating connector and PCB footprint have already been established.

HDR-EA26LFYPG1+ Compact PCB Interconnection

One advantage of a multi-contact board connector is the ability to consolidate many connections into a small physical interface.

HDR-EA26LFYPG1+ can therefore be useful in products where PCB space needs to be managed efficiently.

A consolidated connector can also make the internal architecture cleaner because multiple connections are handled through one defined mating point.

For compact equipment, the connector location should be determined together with the PCB layout and enclosure design rather than being treated as an isolated component.

HDR-EA26LFYPG1+ PCB Footprint

The PCB footprint is a critical consideration when using HDR-EA26LFYPG1+.

The contact positions, spacing, mounting features and connector orientation must correspond to the actual component dimensions.

A footprint that is slightly different from the required configuration can prevent proper assembly or create alignment problems with the mating PCB.

For an existing product, engineers should compare the original PCB footprint with the manufacturer's mechanical information before approving the connector.

HDR-EA26LFYPG1+ Mating Interface

Correct mating is essential for a board to board connector.

HDR-EA26LFYPG1+ should be paired with the appropriate compatible connector specified for the HDR series configuration.

A connector with the same 26 position count does not automatically provide mechanical compatibility.

Differences in pitch, contact arrangement, housing geometry and mating orientation can make otherwise similar connectors incompatible.

This is why the complete MPN is more useful than searching by contact count alone.

HDR-EA26LFYPG1+ Signal Connections

The 26 contacts provide a convenient pathway for multiple electrical signals between connected boards.

Depending on the system architecture, these connections may carry control signals, digital interfaces, power connections or other board level signals.

The connector itself does not define the electrical function of each contact. That function is determined by the PCB circuit and system architecture.

For higher speed signals, engineers should also consider PCB trace routing, impedance, crosstalk and the electrical characteristics of the complete interconnection.

HDR-EA26LFYPG1+ Board Alignment

Board alignment is an important mechanical consideration for any board to board connector.

The mating PCBs need to be positioned accurately so that the contacts engage correctly.

Excessive lateral or vertical force during assembly can place unnecessary stress on the connector.

For products with repeated assembly or service requirements, mechanical supports and PCB positioning features can help maintain the intended connector alignment.

HDR-EA26LFYPG1+ Electronic Equipment Applications

HDR-EA26LFYPG1+ can be used in electronic products requiring a compact multi-contact PCB interconnection.

Typical application areas can include control boards, embedded systems, communication equipment, industrial electronics and modular electronic assemblies.

The 26 position configuration is useful when several electrical connections need to be grouped into one board level interface.

The final application should always be evaluated against the connector's complete electrical and mechanical specifications.

HDR-EA26LFYPG1+ Modular PCB Design

Modular PCB architectures often require a reliable way to connect separate circuit boards.

HDR-EA26LFYPG1+ can serve as the dedicated interface between two board assemblies.

This can allow individual PCB modules to be developed, assembled and serviced more independently.

For example, a control PCB and an interface PCB can be mechanically separated while maintaining their electrical connection through the board connector.

The suitability of this architecture depends on the required board spacing, connector orientation and electrical interface.

HDR-EA26LFYPG1+ Replacement

When searching for an HDR-EA26LFYPG1+ replacement, the 26 position count should only be treated as the starting point.

The replacement needs to match the relevant mechanical and mating characteristics of the original connector.

The PCB footprint is especially important for an existing design.

The replacement should also provide the required contact arrangement and board orientation.

A connector that appears similar but uses a different mating structure may not be a practical replacement even when the number of contacts is identical.

HDR-EA26LFYPG1+ Alternative

An HDR-EA26LFYPG1+ alternative should be evaluated against the complete connector specification.

Engineers should compare the position count, pitch, mating interface, mounting arrangement, orientation, dimensions and electrical requirements.

For a new PCB design, alternative connector families may provide additional design flexibility.

For an existing PCB, however, a mechanically compatible alternative is generally more useful because it can reduce the need for PCB redesign.

HDR-EA26LFYPG1+ Connector Selection

Selecting HDR-EA26LFYPG1+ should begin with the actual requirements of the PCB system.

The designer should determine how many contacts are required, how the two boards are positioned, what mating direction is needed and how much board space is available.

The mechanical relationship between the two PCBs is especially important because board to board connectors are designed around a defined mating geometry.

For high volume products, connector availability and long term sourcing should also be considered during component selection.

HDR-EA26LFYPG1+ PCB Assembly

During PCB assembly, accurate connector placement is important because the contact array must remain aligned with the mating component.

The connector should be installed according to the recommended assembly process and PCB footprint.

Inspection should verify that the connector is seated correctly and that there are no soldering or alignment problems.

For products with multiple board connectors, mechanical tolerances should also be considered to prevent cumulative alignment errors.

HDR-EA26LFYPG1+ Supplier Search

Buyers searching for HDR-EA26LFYPG1+ suppliers should use the complete part number in supplier searches.

Searching for only a 26 position board connector can return products with different mating systems and PCB footprints.

HDR-EA26LFYPG1+ Buying Considerations

Before purchasing HDR-EA26LFYPG1+, buyers should confirm the complete MPN and the exact Hirose connector configuration.

For an existing PCB, the most important checks include the number of positions, contact arrangement, mating connector, footprint and mechanical dimensions.

For a new design, engineers should also consider whether the connector provides sufficient space and the required electrical interface for the intended application.

For production purchasing, availability, packaging, lead time and supplier capability should be verified before placing a larger order.

HDR-EA26LFYPG1+ Product Identification

The exact part number HDR-EA26LFYPG1+ should be retained in the BOM and purchasing records.

Connector families often contain products that look very similar but differ in small mechanical details.

The final + character is part of the ordering designation and should not be casually removed when searching for the component.

Using the complete MPN helps purchasing teams and engineers communicate the exact connector configuration required for the project.
