Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-108-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 8 positions
• Pitch & Spacing: 0.100" (2.54mm) mating pitch, single row
• Contact Specifications: 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
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, operating range -55°C ~ 125°C
• Material Composition: Liquid Crystal Polymer insulation with phosphor bronze contacts

The substitute part SSW-108-01-G-S meets all these criteria and is classified within the same SSW series base product family (SSW-108).

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-108-21-G-S and SSW-108-01-G-S are active production parts manufactured by Samtec Inc. with identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on:

• Inventory Availability: SSW-108-01-G-S maintains higher stock levels (3359 units vs. 976 units), providing greater supply security for high-volume applications.
• Compliance Status: Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting equivalent regulatory requirements.
• Functional Equivalence: Complete parameter alignment ensures direct substitution without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can SSW-108-01-G-S be used as a direct replacement for SSW-108-21-G-S?

A: Yes. Both parts are functionally equivalent across all specified electrical, mechanical, and environmental parameters. No circuit or PCB layout modifications are required.

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

A: No. Both parts feature identical gold mating contact finish (20.0µin thickness), phosphor bronze contact material, and liquid crystal polymer insulation.

Q: What is the difference between the two part numbers?

A: The part numbers differ in their suffix designation (21-G-S vs. 01-G-S), which reflects internal Samtec product line segmentation. This does not affect electrical or mechanical performance.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection may be based on inventory availability, lead time, or supplier preference, as both are active production parts with equivalent specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification.
