Key Parameters

Substitute Part Grouping Explanation

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

• Connector type (Receptacle)
• Number of positions (8)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Contact finish on mating surface (Gold)
• Current rating per contact (4.7A)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (Liquid Crystal Polymer)
• Flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3)

The SSW-108-01-F-S meets all these criteria and is classified as a direct substitute. Both parts share the same base product number (SSW-108) and series designation, confirming functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-108-21-F-S and SSW-108-01-F-S are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on availability and inventory requirements. The SSW-108-01-F-S offers significantly higher stock availability (6206 units versus 893 units), making it suitable for high-volume applications or extended lead-time mitigation. Both parts are functionally and mechanically equivalent for all electrical and thermal operating conditions. The difference in Moisture Sensitivity Level designation does not affect substitution eligibility, as both are suitable for standard PCB assembly environments.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector type, position count, pitch, mounting method, contact materials, current rating, and operating temperature range. They share the same base product number and series designation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: 8-position receptacle configuration, 0.100" (2.54mm) pitch, through-hole mounting, gold-plated mating contacts, 4.7A per contact rating, -55°C to 125°C operating range, Liquid Crystal Polymer insulation, UL94 V-0 flammability rating, and ROHS3 compliance.

Q: Are there any differences in packaging or handling between these parts?

A: Both parts are supplied in bulk packaging. The Moisture Sensitivity Level differs (Not Applicable for SSW-108-21-F-S versus MSL 1 for SSW-108-01-F-S), but this does not affect compatibility or substitution suitability for standard PCB assembly processes.

Q: Which part should be selected for new designs?

A: Selection should be based on inventory availability and supply chain requirements. The SSW-108-01-F-S provides higher stock levels and is suitable for applications requiring extended availability. Both parts are active production items with identical electrical and mechanical specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-108-21-F-S and SSW-108-01-F-S are ROHS3 compliant and carry EAR99 export classification.
