Engineering Selection Recommendations

Both substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the A-CCS32-Z-R.

The A-CCS 032-Z-T is the primary substitute from the original manufacturer Assmann WSW Components. This part maintains the same PLCC 32-position configuration and is currently in active production status with ROHS3 compliance certification. The contact resistance is improved at 15mOhm compared to the original 30mOhm specification. The operating temperature range is -40°C to 105°C, which covers the upper operating point of the original part. Post length is marginally longer at 0.132" versus 0.130", which is within acceptable PCB design tolerances for through-hole mounting.

The 8432-11B1-RK-TP from 3M (Series 8400) is an alternative substitute with significantly higher inventory availability. This part meets all critical substitution parameters and carries ROHS3 compliance. The contact material differs as copper alloy rather than phosphor bronze, but both materials are standard for PLCC socket applications and provide equivalent electrical performance at the specified 1 A current rating. Post length and termination specifications are identical to the Assmann substitute.

Both substitutes are suitable for applications requiring the original A-CCS32-Z-R specifications. Selection between them should be based on supply chain preferences, inventory requirements, and any existing qualification history with either manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the A-CCS 032-Z-T and 8432-11B1-RK-TP be used interchangeably with the A-CCS32-Z-R?

A: Both parts are electrically and mechanically equivalent for the specified application. They share identical PLCC 32-position configuration, 0.050" mating pitch, 0.100" post pitch, 1 A current rating, and UL94 V-0 flammability rating. Both are suitable for direct substitution in through-hole PCB designs.

Q: What is the significance of the contact material difference between phosphor bronze and copper alloy?

A: Both phosphor bronze and copper alloy are standard contact materials for PLCC sockets. The contact resistance and electrical performance are equivalent at the 1 A current rating specified for this application. The choice between materials does not affect functional compatibility.

Q: Does the post length difference of 0.002" (0.05mm) between the original and substitute parts affect PCB design?

A: The post length variation from 0.130" to 0.132" is within standard PCB design tolerances for through-hole components. This minor difference does not require PCB layout modifications and does not affect solder joint quality or mechanical reliability.

Q: Are the substitute parts RoHS compliant?

A: Both the A-CCS 032-Z-T and 8432-11B1-RK-TP are ROHS3 compliant. The original A-CCS32-Z-R RoHS status is not specified in the available documentation.

Q: What is the difference in operating temperature range between the original and substitute parts?

A: The original A-CCS32-Z-R operates from -55°C to 105°C. Both substitute parts operate from -40°C to 105°C. The lower temperature limit is 15°C higher in the substitutes. For applications requiring operation below -40°C, the original part specifications must be verified for availability or alternative solutions considered.

Q: Which substitute part should be selected for new designs?

A: Both substitutes are suitable for new designs. The A-CCS 032-Z-T maintains the original manufacturer relationship with Assmann WSW Components. The 8432-11B1-RK-TP offers significantly higher inventory availability through 3M. Selection should align with supply chain strategy and existing component qualification requirements.
