CPAT-181-A1-G-15AK

Overview

The CPAT-181-A1-G-15AK is a Pin Grid Array (PGA) IC socket manufactured by Samtec Inc. It features 181 contact positions arranged in a 15x15 grid configuration with a 2.54 mm terminal pitch and 0.1-inch row spacing. The component utilizes solder termination for board mounting and includes gold plating over nickel on the contacts to ensure reliable electrical connection. Designed specifically for PGA181 devices, this low-profile socket supports high-cycle durability and complies with RoHS standards.

Feature Summary

• Provides secure mechanical retention and electrical connectivity for PGA181 integrated circuits
• Features gold-over-nickel contact plating to enhance corrosion resistance and signal integrity
• Designed with a low-profile body style to minimize vertical space requirements on the PCB

Applications

• Socketing PGA181 microprocessors or memory modules during prototyping
• High-reliability interconnects in industrial control systems
• Testing and burn-in fixtures for electronic components

Procurement Notes

Verify that the specific ordering suffix matches the required pin count and plating thickness. Confirm compliance with current environmental regulations such as RoHS before finalizing procurement. Ensure the selected variant aligns with the target PGA package dimensions and thermal requirements of the application design.

Selection Notes

Select this socket when interfacing with PGA181 packages requiring robust mechanical stability. Consider the low-profile form factor if board height constraints are critical. Verify that the solder termination method is compatible with the assembly process and that the contact material meets the necessary conductivity standards for the intended signal paths.

Part Context

This component belongs to the MPAS/MVAS/MSAS family of Pin Grid Array sockets produced by Samtec. These sockets are engineered to mate with various PGA packages including MPAT, MVAT, MHAT, and MSAT series components. The family offers different insulator materials and contact configurations to suit diverse electronic packaging needs.

Replacement Considerations

Consult official Samtec documentation for direct cross-reference part numbers within the MPAS or MSAS series. Verify that any substitute maintains identical pin counts, pitch specifications, and mating compatibility with the target PGA181 device.
