Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-822473-2 is determined by strict alignment with the following critical parameters:

Core Compatibility Requirements:

• Type: PLCC Socket
• Number of Positions: 28 (4 x 7) grid configuration
• Pitch - Mating: 0.050" (1.27mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Contact Finish: Tin
• Features: Closed Frame
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Both identified substitute parts meet all core compatibility requirements. The substitutes are active products with current manufacturing status, addressing the obsolescence of the original part while maintaining identical mechanical and electrical interface specifications.

Engineering Selection Recommendations

Assmann WSW Components A-CCS 028-Z-T

The Assmann A-CCS 028-Z-T is an active product with ROHS3 compliance and REACH unaffected status. This substitute maintains identical mechanical interface specifications and closed-frame PLCC socket configuration. The part features enhanced contact finish thickness (160.0µin versus 80.0µin on the original), phosphor bronze contact material, and specified operating temperature range of -40°C to 105°C. Current availability is 1660 pieces in stock.

3M 8428-11B1-RK-TP (Series 8400)

The 3M 8428-11B1-RK-TP is an active product with ROHS3 compliance and REACH unaffected status. This substitute provides identical mechanical interface specifications with closed-frame PLCC socket configuration. The part features enhanced contact finish thickness (160.0µin), copper alloy contact material, and specified operating temperature range of -40°C to 105°C. Current availability is 2219 pieces in stock.

Both substitutes are suitable for applications requiring active product status and regulatory compliance. Selection between the two should be based on specific contact material requirements and inventory availability for the application.

Frequently Asked Questions (FAQ)

Q: Can the Assmann A-CCS 028-Z-T or 3M 8428-11B1-RK-TP be used as direct replacements for the TE Connectivity 1-822473-2?

A: Yes. Both substitute parts maintain identical pitch specifications (0.050" mating, 0.100" post), 28-position PLCC configuration, through-hole mounting, closed-frame design, and solder termination. All three parts are UL94 V-0 rated, ROHS3 compliant, and have MSL 1 rating.

Q: What is the difference in contact finish thickness between the original part and the substitutes?

A: The TE Connectivity 1-822473-2 has 80.0µin (2.03µm) contact finish thickness on both mating and post contacts. Both substitute parts provide 160.0µin (4.06µm) contact finish thickness, which is double the original specification.

Q: Are there differences in contact material between the substitutes?

A: The Assmann A-CCS 028-Z-T uses phosphor bronze for both mating and post contacts, matching the original TE Connectivity part. The 3M 8428-11B1-RK-TP uses copper alloy for both mating and post contacts.

Q: What is the housing material difference?

A: The TE Connectivity 1-822473-2 uses thermoplastic housing. The Assmann A-CCS 028-Z-T uses polybutylene terephthalate (PBT). The 3M 8428-11B1-RK-TP uses polybutylene terephthalate (PBT) with glass filling for enhanced mechanical properties.

Q: Do the substitute parts have specified operating temperature ranges?

A: Yes. Both the Assmann A-CCS 028-Z-T and 3M 8428-11B1-RK-TP specify operating temperature ranges of -40°C to 105°C. The original TE Connectivity part does not provide an operating temperature specification.

Q: What is the current rating for these PLCC sockets?

A: The Assmann A-CCS 028-Z-T and 3M 8428-11B1-RK-TP both specify a current rating of 1 A. The original TE Connectivity part does not provide a current rating specification.

Q: Is contact resistance specified for all parts?

A: The Assmann A-CCS 028-Z-T specifies contact resistance of 15mOhm. The TE Connectivity 1-822473-2 and 3M 8428-11B1-RK-TP do not provide contact resistance specifications.

Q: Are all parts compliant with RoHS and REACH regulations?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these components?

A: All three parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions.
