A-CCS52-Z-R PLCC 52-Position Socket Equivalent & Substitute Parts

Part Overview

The A-CCS52-Z-R is a 52-position PLCC socket manufactured by Assmann WSW Components, designed for through-hole mounting applications. This component features a closed frame design with tin-plated phosphor bronze contacts and is rated for 1 A current with a contact resistance of 30 mOhm. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications. Equivalent parts must maintain the same electrical and mechanical specifications to ensure direct compatibility in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-CCS52-Z-R is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Type: PLCC socket
• Number of Positions: 52 (4 x 13) grid configuration
• Pitch - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole
• Contact Finish - Mating: Tin
• Contact Material - Mating: Phosphor Bronze or equivalent copper alloy
• Current Rating: 1 A minimum
• Flammability Rating: UL94 V-0
• Termination: Solder

Allowable Variations:

• Contact Finish Thickness - Mating: 150.0µin to 160.0µin (3.81µm to 4.06µm)
• Operating Temperature Range: Minimum -40°C to maximum 105°C (original specification -55°C to 105°C)
• Pitch - Post: 0.050" (1.27mm) or 0.100" (2.54mm)
• Contact Resistance: Up to 30 mOhm
• Housing Material: PBT with or without glass fill
• Product Status: Active preferred over obsolete

Two substitute parts meet these criteria and are identified below.

Engineering Selection Recommendations

A-CCS 052-Z-T (Assmann WSW Components)

This substitute is the direct manufacturer evolution of the obsolete A-CCS52-Z-R. It maintains identical electrical and mechanical specifications with the exception of operating temperature minimum (-40°C versus -55°C) and improved contact resistance (15 mOhm versus 30 mOhm). The part is currently in active production status with ROHS3 compliance certification. The post pitch remains at 0.100" (2.54mm), matching the original design. This part is suitable for applications where the operating temperature range does not require operation below -40°C.

8452-11B1-RK-TP (3M Series 8400)

This substitute is manufactured by 3M and meets all mandatory electrical and mechanical parameters. It features a different post pitch of 0.050" (1.27mm) compared to the original 0.100" (2.54mm), which requires PCB layout verification before implementation. The part is in active production with ROHS3 compliance. Contact resistance is not specified in available documentation. This part is suitable for applications where PCB footprint accommodates the 0.050" post pitch spacing.

Frequently Asked Questions (FAQ)

Q: Can A-CCS 052-Z-T be used as a direct replacement for A-CCS52-Z-R without PCB modification?

A: Yes, A-CCS 052-Z-T maintains identical post pitch (0.100" / 2.54mm) and all critical electrical specifications. No PCB layout changes are required. The operating temperature minimum is -40°C instead of -55°C; verify this meets application requirements.

Q: What is the key difference between the two substitute parts?

A: The primary difference is post pitch. A-CCS 052-Z-T uses 0.100" (2.54mm) post pitch, matching the original design. The 3M 8452-11B1-RK-TP uses 0.050" (1.27mm) post pitch, requiring PCB footprint verification and potential layout redesign.

Q: Are both substitute parts RoHS compliant?

A: Yes, both A-CCS 052-Z-T and 8452-11B1-RK-TP are ROHS3 compliant. The original A-CCS52-Z-R RoHS status is not specified in available documentation.

Q: What is the significance of the contact resistance difference between A-CCS52-Z-R (30 mOhm) and A-CCS 052-Z-T (15 mOhm)?

A: The lower contact resistance in A-CCS 052-Z-T represents improved electrical performance and reduced signal loss. This is a beneficial characteristic and does not create compatibility issues with the original design.

Q: Can the 3M 8452-11B1-RK-TP be used if my PCB is designed for 0.100" post pitch?

A: No. The 3M part uses 0.050" post pitch, which is incompatible with PCB footprints designed for 0.100" spacing. PCB redesign would be required.

Q: What is the operating temperature limitation when using A-CCS 052-Z-T?

A: A-CCS 052-Z-T operates from -40°C to 105°C, compared to the original -55°C to 105°C. Applications requiring operation below -40°C must use the original part or identify alternative solutions.
