S42C163243JP CTS 8-Resistor 24kΩ Chip Resistor Array

ElecSuppliers Part Number GuideAug 22, 2026

S42C163243JP is a CTS Electronic Components S4x series chip resistor array designed for compact electronic circuits that require multiple resistors in a single surface-mount component. The device integrates eight individual 24 kΩ resistors into a 16-pin package and uses an isolated circuit configuration.

The component is designed for applications where several separate resistors would otherwise occupy more PCB space. By integrating multiple resistive elements into one package, resistor arrays can simplify PCB layout and reduce the number of individual components required.

S42C163243JP Key Specifications

S42C163243JP contains eight individual resistive elements, each with a nominal resistance of 24 kΩ. The resistance tolerance is ±5%, while the temperature coefficient is ±200 ppm/°C.

The resistor elements are isolated from one another, allowing each resistor to function as an independent circuit element rather than being connected internally to a common terminal.

The component has a 50 V voltage rating and a power rating of 63 mW per resistor element.

8-Resistor Chip Array

The main advantage of S42C163243JP is the integration of eight resistors into a single component.

In a conventional circuit, eight individual chip resistors would require eight separate placement operations and eight separate PCB footprints. A resistor array can consolidate these components into one package, helping reduce board area and simplify assembly.

The isolated configuration is especially useful when several independent pull-up, pull-down, biasing or signal-conditioning resistors are required in the same circuit.

This type of arrangement is commonly found around digital interfaces, memory devices, controllers and other circuits containing multiple signals with similar resistor requirements.

S42C163243JP Package

S42C163243JP uses a compact 2506 package with dimensions of approximately 6.4 mm × 1.6 mm and a height of about 0.45 mm.

The component is designed for surface-mount PCB assembly and uses 16 pins to provide independent connections for the eight resistor elements.

The compact package can help reduce PCB space compared with eight individually mounted resistors. It can also make automated assembly more efficient because one component placement replaces multiple resistor placements.

CTS S4x Sulfur-Resistant Design

S42C163243JP belongs to the CTS S4x series, which is designed with sulfur resistance in mind.

Sulfur-containing environments can create reliability problems for conventional thick-film chip resistors. Sulfur can react with exposed silver-based internal conductors and form silver sulfide, potentially increasing resistance or causing an open circuit.

The S4x design incorporates a protective barrier intended to reduce sulfur penetration into the internal conductive structure. This characteristic makes the series useful in equipment that may operate in environments where sulfur exposure is a concern.

S42C163243JP Electrical Characteristics

Each resistor in the array has a resistance value of 24 kΩ and a tolerance of ±5%. The 200 ppm/°C temperature coefficient indicates how the resistance can change as the component temperature varies.

The maximum operating temperature is 125°C, while the minimum operating temperature is -55°C.

These characteristics allow the component to be used across a relatively wide operating temperature range. However, the actual performance of the resistor array still depends on the electrical load, PCB thermal conditions and surrounding environment.

Applications for S42C163243JP

S42C163243JP can be used in digital electronics, industrial control equipment, communication equipment, embedded systems and other PCB assemblies requiring multiple independent resistor elements.

Typical circuit functions can include signal biasing, pull-up and pull-down networks, voltage division and interface conditioning.

The eight independent 24 kΩ resistors make the device particularly useful when several circuit nodes require the same resistance value.

For example, a board containing multiple digital signal lines may require a group of identical resistors. Using a resistor array can simplify both the schematic and PCB layout.

S42C163243JP PCB Design

Because S42C163243JP contains eight independent resistors in a single 16-pin package, the PCB footprint differs considerably from that of a conventional single chip resistor.

The 2506 package has a long and narrow profile, with approximately 0.8 mm lead spacing. Designers should use the manufacturer's recommended land pattern to ensure reliable soldering.

The compact package also allows several resistor functions to be placed close together. This can be beneficial for signal-conditioning circuits where the resistors need to be located close to the corresponding IC pins.

S42C163243JP Replacement Considerations

When replacing S42C163243JP, engineers should check the complete resistor-array configuration rather than looking only at the 24 kΩ resistance value.

Important parameters include the number of resistors, isolated circuit configuration, resistance tolerance, temperature coefficient, package dimensions, pin arrangement and power rating per element.

A resistor array with eight resistors connected to a common terminal is not an equivalent replacement for an isolated eight-resistor array.

The package also needs to match the PCB footprint and pin spacing. Even when the electrical specifications appear similar, a different resistor-array configuration may require PCB changes.

S42C163243JP Availability

S42C163243JP continues to be listed by electronic component distributors as a CTS Electronic Components part. Current distributor listings identify the exact configuration as an S4x series surface-mount resistor array with eight 24 kΩ isolated resistors.

Current availability varies by distributor. Some listings show the component as non-stocked with a factory lead time, while other component sources list available quantities.

For production procurement, buyers should confirm the current stock level, manufacturer part number, packaging quantity and lead time before placing an order.

S42C163243JP for Compact PCB Designs

S42C163243JP provides eight independent 24 kΩ resistors in a compact surface-mount package. Its isolated configuration makes it suitable for circuits where several separate resistor elements are required in a limited PCB area.

The S4x sulfur-resistant construction adds another useful characteristic for equipment exposed to potentially corrosive environments.

For new designs, engineers should verify the resistor-array pin configuration, power dissipation, temperature range and PCB footprint. For replacement applications, matching the complete S42C163243JP specification is important because resistor arrays with similar resistance values can have very different internal circuit configurations.
