Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-124-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 24 positions
• Pitch & Mounting: 0.100" (2.54mm) mating pitch with through-hole PCB mounting
• Contact Specifications: Forked contact type with gold plating on mating surfaces
• Electrical Performance: 4.7A per contact current rating
• Thermal & Compliance: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating, ROHS3 compliance

The identified substitute part SSW-124-01-G-S meets all these criteria, differing only in internal design designation (01 vs. 21 suffix) while maintaining identical functional and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-124-21-G-S and SSW-124-01-G-S are active production parts with full ROHS3 compliance and identical electrical, mechanical, and thermal specifications. Selection between these parts should be based on:

• Inventory Availability: SSW-124-01-G-S has higher stock levels (717 units vs. 612 units)
• Supply Chain Requirements: Both parts are manufactured by Samtec Inc. and carry the same ECCN and HTSUS classifications
• Design Documentation: Verify that design schematics and PCB layouts reference the SSW-124 base product number, which accommodates both variants

No functional or performance differences exist between these parts. Direct substitution is permissible in applications where the SSW-124-21-G-S is specified.

Frequently Asked Questions (FAQ)

Q: Can SSW-124-01-G-S be used as a direct replacement for SSW-124-21-G-S?

A: Yes. Both parts are functionally equivalent across all electrical, mechanical, and thermal parameters. The suffix designation (01 vs. 21) reflects internal design variants within the SSW-124 base product family but does not affect connector performance, mating compatibility, or PCB footprint.

Q: Are there any differences in contact plating or material composition?

A: No. Both parts use identical phosphor bronze contacts with 20.0µin (0.51µm) gold plating on mating surfaces and 3.00µin (0.076µm) gold plating on post terminations. Insulation material, color, and dimensions are identical.

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

A: Both parts are rated for 4.7A per contact, supporting the same electrical load capacity in board-to-board and cable applications.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-124-21-G-S and SSW-124-01-G-S are ROHS3 compliant and carry EAR99 export classification.

Q: What is the operating temperature range?

A: Both parts operate across -55°C to 125°C, with UL94 V-0 flammability rating for the liquid crystal polymer insulation material.

Q: Do these connectors require any special handling or storage conditions?

A: Moisture sensitivity level is not applicable for these parts. Standard ESD precautions are recommended during handling and assembly.
