Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-142-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts must be 42-position receptacles
• Pitch & Mating Interface: 0.100" (2.54mm) pitch maintained for mechanical compatibility
• Contact Configuration: Forked contact type with gold mating finish
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Electrical Performance: 4.7A per contact current rating and -55°C ~ 125°C operating temperature range
• Material & Compliance: Liquid Crystal Polymer insulation, UL94 V-0 flammability rating, and ROHS3 compliance

The substitute part SSW-142-01-G-S meets all these criteria, differing only in internal design designation (01 vs. 21) while maintaining identical functional and electrical specifications within the SSW series.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-142-21-G-S and SSW-142-01-G-S are active production parts with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability: SSW-142-21-G-S has higher inventory (1,002 units) compared to SSW-142-01-G-S (747 units)
• Supply Chain Requirements: Either part satisfies equivalent design requirements for 42-position, 0.100" pitch receptacle applications
• Regulatory Compliance: Both parts meet UL94 V-0 flammability and ROHS3 requirements for regulated applications

No additional testing or qualification is required when substituting between these parts within the same design application, provided the connector footprint and mating interface remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can SSW-142-01-G-S be used as a direct replacement for SSW-142-21-G-S?

A: Yes. Both parts are 42-position receptacles with identical pitch (0.100"), contact configuration, current rating (4.7A per contact), operating temperature range (-55°C ~ 125°C), and material specifications. The internal designation difference (01 vs. 21) does not affect functional compatibility.

Q: Are there any mechanical differences between these connectors?

A: No. Both connectors share identical mechanical dimensions, including insulation height (0.335"), contact length (0.104"), and contact finish specifications. PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-142-21-G-S and SSW-142-01-G-S are ROHS3 compliant, UL94 V-0 rated, and classified under the same ECCN (EAR99) and HTSUS codes.

Q: What is the current rating per contact for these connectors?

A: Both connectors are rated for 4.7A per contact, supporting equivalent electrical loads in board-to-board and cable applications.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts operate across the -55°C ~ 125°C temperature range, making them suitable for industrial and automotive environments within this specification.

Q: What is the mating pitch for these connectors?

A: Both connectors use a 0.100" (2.54mm) mating pitch, the standard spacing for this connector family.
