A-CCS 068-Z-SM PLCC 68-Position IC Socket Equivalent & Substitute Parts

Part Overview

The A-CCS 068-Z-SM is a 68-position PLCC surface mount IC socket manufactured by Assmann WSW Components. This component is classified as an active product and serves as a connection interface for PLCC-packaged integrated circuits in electronic assemblies. The socket features tin-plated phosphor bronze contacts with a closed frame design and is suitable for operating environments ranging from -40°C to 105°C. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and supply chain continuity for applications requiring 68-position PLCC socket functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-CCS 068-Z-SM is determined by strict alignment of the following critical parameters:

• Type: PLCC socket configuration
• Number of Positions: 68 (4 x 17) grid
• Pitch - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Contact Finish - Mating: Tin
• Operating Temperature Range: -40°C ~ 105°C minimum
• Current Rating: 1 A minimum
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in contact material composition (phosphor bronze versus copper alloy), housing material (polyamide versus polybutylene terephthalate), contact finish thickness, and termination post length do not preclude functional equivalence within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with ROHS3 and UL94 V-0 flammability requirements. Selection among equivalent parts should be based on:

3M 8468-21A1-RK-TP and 8468-21B1-RK-TP: These parts are direct functional equivalents with identical electrical and mechanical specifications to the A-CCS 068-Z-SM. Both utilize copper alloy contact material and polybutylene terephthalate housing. The 8468-21B1-RK-TP offers higher inventory availability (2543 pcs) compared to the 8468-21A1-RK-TP (835 pcs).

Adam Tech PLCC-68-AT-SMT: This part provides an extended operating temperature range (-55°C ~ 105°C) compared to the primary part and 3M alternatives. Contact material composition matches the A-CCS 068-Z-SM (phosphor bronze). Contact finish thickness is reduced to 80.0µin (2.03µm), and contact resistance is specified at 30mOhm. This part is suitable for applications requiring the extended lower temperature specification.

Frequently Asked Questions (FAQ)

Q: Can the 3M 8468-21A1-RK-TP and 8468-21B1-RK-TP be used interchangeably with the A-CCS 068-Z-SM?

A: Yes. Both 3M parts meet all critical electrical and mechanical parameters including pin count, pitch, mounting type, contact finish, operating temperature range, current rating, and compliance certifications. The primary difference is contact material composition (copper alloy versus phosphor bronze), which does not affect functional equivalence within the specified parameter envelope.

Q: What is the difference between the Adam Tech PLCC-68-AT-SMT and the other substitute parts?

A: The Adam Tech part provides an extended operating temperature range of -55°C ~ 105°C, compared to -40°C ~ 105°C for the other parts. It also features phosphor bronze contact material matching the A-CCS 068-Z-SM. Contact finish thickness is thinner (80.0µin versus 160.0µin), and contact resistance is higher (30mOhm versus 15mOhm). Selection should be based on specific application temperature requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting regulatory requirements for electronic component applications.

Q: What is the significance of contact finish thickness variation?

A: Contact finish thickness affects durability and wear characteristics. The A-CCS 068-Z-SM and 3M parts specify 160.0µin (4.06µm) tin plating, while the Adam Tech part specifies 80.0µin (2.03µm). Both thicknesses are within acceptable engineering ranges for PLCC socket applications and do not preclude functional substitution.

Q: Can the Adam Tech PLCC-68-AT-SMT be used in applications requiring the lower temperature specification of -40°C?

A: Yes. The Adam Tech part's operating range of -55°C ~ 105°C encompasses the -40°C ~ 105°C requirement of the primary part, making it suitable for such applications.
