A-CCS84-G PLCC 84-Position Socket - Equivalent & Substitute Parts

Part Overview

The A-CCS84-G is a 84-position PLCC (Plastic Leaded Chip Carrier) socket manufactured by Assmann WSW Components, designed for through-hole mounting applications. This component features gold-plated contacts and phosphor bronze materials for reliable electrical performance in IC and transistor socket applications. The A-CCS84-G is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A-CCS84-G is determined by strict equivalence across the following critical parameters:

• Pin Configuration: 84 positions in 4 x 21 grid arrangement
• Mating Pitch: 0.050" (1.27mm) - determines physical fit with PLCC components
• Post Pitch: 0.100" (2.54mm) - determines PCB hole spacing compatibility
• Contact Material & Finish: Gold-plated phosphor bronze for both mating and post surfaces
• Mounting Type: Through-hole solder termination
• Housing Material: Polybutylene Terephthalate (PBT)
• Electrical Performance: 1 A current rating, contact resistance specifications
• Environmental Compliance: UL94 V-0 flammability rating, REACH and ECCN classifications

The substitute part A-CCS 084-G-T maintains these critical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The A-CCS 084-G-T is a direct functional equivalent to the obsolete A-CCS84-G. Selection of the substitute part is supported by the following factors:

Electrical Equivalence: Both parts maintain identical pin configuration, pitch specifications, contact materials, and current ratings. The substitute part demonstrates superior contact resistance (15mOhm versus 30mOhm), indicating improved electrical performance.

Mechanical Compatibility: Pin grid arrangement, mounting type, and post pitch are identical. Termination post length variation (0.002") is within manufacturing tolerance and does not affect PCB assembly compatibility.

Environmental & Compliance Alignment: Both parts carry UL94 V-0 flammability certification and identical REACH and ECCN classifications. The substitute part includes RoHS3 compliance documentation.

Product Status Advantage: The A-CCS 084-G-T is actively manufactured by Assmann WSW Components, ensuring long-term availability and supply chain reliability compared to the obsolete A-CCS84-G.

Temperature Range Consideration: The substitute part operates across -40°C to 105°C, which is 15°C narrower at the lower temperature limit. Applications requiring operation below -40°C must evaluate this specification against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the A-CCS 084-G-T be used as a direct replacement for the A-CCS84-G in existing designs?

A: Yes. The substitute part maintains identical pin configuration, pitch specifications, contact materials, and electrical ratings. The 0.002" difference in termination post length is within standard manufacturing tolerance and does not affect PCB hole compatibility or assembly processes.

Q: What is the significance of the contact resistance difference between the two parts?

A: The A-CCS 084-G-T exhibits lower contact resistance (15mOhm versus 30mOhm), which represents improved electrical performance and reduced voltage drop across the socket contacts. This is a beneficial characteristic for applications sensitive to contact resistance.

Q: Does the operating temperature range difference affect substitution suitability?

A: The A-CCS 084-G-T operates from -40°C to 105°C, compared to the A-CCS84-G range of -55°C to 105°C. Applications requiring operation below -40°C must confirm that the substitute part meets system temperature requirements. For applications within the -40°C to 105°C range, the substitute is fully suitable.

Q: What is the difference between the housing materials specified for each part?

A: The A-CCS84-G specifies PBT with glass filler, while the A-CCS 084-G-T specifies PBT without explicit glass filler notation. Both materials are polybutylene terephthalate with UL94 V-0 certification. This material variation does not affect electrical or mechanical compatibility for standard through-hole socket applications.

Q: Is the tube packaging of the A-CCS 084-G-T compatible with existing assembly processes?

A: Tube packaging is standard for component distribution and is compatible with automated and manual assembly processes. Verify that receiving and component handling procedures accommodate tube packaging if the original A-CCS84-G was supplied in alternative packaging.

Q: Are both parts RoHS compliant?

A: The A-CCS 084-G-T is explicitly documented as RoHS3 compliant. The A-CCS84-G does not include RoHS compliance documentation in the provided specifications. For applications requiring RoHS compliance certification, the A-CCS 084-G-T provides documented compliance.
