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

Part Overview

The A-CCS 052-Z-T is a 52-position PLCC (Plastic Leaded Chip Carrier) socket manufactured by Assmann WSW Components. This through-hole mounted socket is designed for IC and transistor applications requiring a closed-frame PLCC interface. The part is currently active in production with 783 units in stock. Alternative equivalent parts may be required due to supply chain considerations, inventory availability, or specific application requirements where substitute specifications remain within acceptable electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A-CCS 052-Z-T is permissible with parts meeting the following criteria:

Critical Parameters (Must Match Exactly):

• Type: PLCC
• Number of Positions: 52 (4 x 13)
• Pitch - Mating: 0.050" (1.27mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Contact Material: Phosphor Bronze
• Contact Finish: Tin (both mating and post)

Allowable Variations:

• Contact Finish Thickness - Mating: 80.0µin (2.03µm) to 160.0µin (4.06µm)
• Contact Finish Thickness - Post: 80.0µin (2.03µm) to 160.0µin (4.06µm)
• Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
• Contact Resistance: Up to 30mOhm
• Termination Post Length: 0.126" (3.20mm) to 0.132" (3.35mm)
• Housing Material: PBT or PBT with glass fill
• Current Rating: 1 A minimum
• Flammability Rating: UL94 V-0
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected

The PLCC-52-AT from Adam Tech qualifies as an equivalent substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the A-CCS 052-Z-T and PLCC-52-AT are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for current and future applications. The PLCC-52-AT offers an extended operating temperature range (-55°C to 105°C versus -40°C to 105°C), providing additional thermal margin for demanding environments. The contact resistance specification of the PLCC-52-AT (30mOhm) remains within acceptable limits for standard PLCC socket applications. Both parts maintain identical mechanical interfaces, electrical ratings, and safety certifications. Selection between these parts should be based on availability, lead time, and specific application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the PLCC-52-AT be used as a direct replacement for the A-CCS 052-Z-T?

A: Yes. Both parts share identical PLCC socket specifications including 52-position configuration, 0.050" mating pitch, 0.100" post pitch, through-hole mounting, phosphor bronze contacts with tin finish, and UL94 V-0 flammability rating. The mechanical and electrical interfaces are fully compatible.

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

A: The A-CCS 052-Z-T specifies 160.0µin (4.06µm) tin finish thickness while the PLCC-52-AT specifies 80.0µin (2.03µm). Both thicknesses provide adequate corrosion protection and electrical conductivity for PLCC socket applications. The thinner finish on the PLCC-52-AT does not compromise performance within the specified current rating of 1 A.

Q: Does the glass-filled PBT housing material in the PLCC-52-AT affect compatibility?

A: No. Glass-filled PBT provides equivalent mechanical and thermal properties to standard PBT for socket applications. The glass fill enhances dimensional stability and does not alter the socket's interface characteristics or mounting footprint.

Q: Why does the PLCC-52-AT have a lower contact resistance specification?

A: The PLCC-52-AT specifies 30mOhm contact resistance compared to 15mOhm for the A-CCS 052-Z-T. Both values are acceptable for PLCC socket applications at the 1 A current rating. The higher specification on the substitute part reflects different manufacturing tolerances and does not indicate reduced performance.

Q: Are there any temperature-related considerations when substituting these parts?

A: The PLCC-52-AT operates across -55°C to 105°C, exceeding the A-CCS 052-Z-T range of -40°C to 105°C. For applications operating below -40°C, the PLCC-52-AT provides additional thermal margin. For standard applications within -40°C to 105°C, both parts perform identically.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the A-CCS 052-Z-T and PLCC-52-AT are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.
