A-CCS 052-Z-SM PLCC 52-Position Socket Equivalent & Substitute Parts

Part Overview

The A-CCS 052-Z-SM is a 52-position PLCC socket manufactured by Assmann WSW Components, designed for surface mount applications requiring reliable interconnection of PLCC integrated circuits. This component is classified as active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts become necessary when addressing supply chain constraints, lead time requirements, or inventory optimization while maintaining electrical and mechanical compatibility with the original design specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-CCS 052-Z-SM is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Type: PLCC Socket
• Number of Positions: 52 (4 x 13)
• Pitch - Mating: 0.050" (1.27mm)
• Pitch - Post: 0.050" (1.27mm)
• Contact Finish - Mating: Tin
• Contact Finish - Post: Tin
• Contact Finish Thickness: 160.0µin (4.06µm)
• Mounting Type: Surface Mount
• Features: Closed Frame
• Termination: Solder
• Operating Temperature Range: -40°C ~ 105°C
• Current Rating: 1 A
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts 8452-21A1-RK-TP and 8452-21B1-RK-TP (both manufactured by 3M, Series 8400) meet all mandatory matching parameters. Both parts are active product status with identical electrical and mechanical specifications, differing only in contact material composition (Copper Alloy versus Phosphor Bronze) and housing material (PBT Glass Filled versus PA9T Glass Filled), which remain within acceptable substitution boundaries for PLCC socket applications.

Parameter Comparison

Engineering Selection Recommendations

Both 3M substitute parts (8452-21A1-RK-TP and 8452-21B1-RK-TP) are qualified equivalents for the A-CCS 052-Z-SM based on active product status, full RoHS3 compliance, and identical electrical and mechanical specifications across all critical parameters. Selection between the Assmann original and 3M substitutes should be based on availability, lead time, and inventory requirements. Both 3M parts maintain equivalent performance characteristics within the specified operating temperature range and current rating. The difference in contact material composition (Copper Alloy versus Phosphor Bronze) and housing material (PBT versus PA9T) does not affect functional compatibility in standard PLCC socket applications where the specified electrical and thermal parameters are maintained.

Frequently Asked Questions (FAQ)

Q: Can 8452-21A1-RK-TP and 8452-21B1-RK-TP be used interchangeably with A-CCS 052-Z-SM?

A: Yes. Both 3M parts meet all mandatory electrical and mechanical specifications for the A-CCS 052-Z-SM, including pitch, contact finish, operating temperature range, current rating, and compliance certifications. They are direct functional equivalents for PLCC 52-position socket applications.

Q: What is the difference between the two 3M substitute parts?

A: The 8452-21A1-RK-TP and 8452-21B1-RK-TP are both 3M Series 8400 PLCC 52-position sockets with identical electrical and mechanical specifications. Both are functionally equivalent to the A-CCS 052-Z-SM. Differences in contact material composition and housing material do not affect compatibility in standard applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The A-CCS 052-Z-SM, 8452-21A1-RK-TP, and 8452-21B1-RK-TP are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the operating temperature range for these sockets?

A: All three parts operate within the range of -40°C to 105°C, ensuring compatibility across standard industrial and commercial applications.

Q: Is contact resistance specified for all parts?

A: Contact resistance is specified for the A-CCS 052-Z-SM at 15mOhm. Contact resistance values are not provided in the specification data for the 3M substitute parts; however, both maintain the same tin contact finish and thickness specifications.
