Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-125-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 25 positions
• Pitch & Mounting: 0.100" (2.54mm) mating pitch with through-hole PCB mounting
• Contact & Termination: Forked gold-plated contacts with solder termination
• Electrical Performance: 4.7A per contact current rating and -55°C ~ 125°C operating temperature range
• Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The identified substitute part SSW-125-01-G-S maintains all critical electrical and mechanical parameters, differing only in internal configuration designation within the SSW-125 series. Both parts are manufactured by Samtec Inc. and share identical functional specifications for receptacle connectivity applications.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-125-21-G-S and SSW-125-01-G-S are active production parts manufactured by Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on availability and inventory status. The SSW-125-21-G-S currently maintains 791 units in stock, while the SSW-125-01-G-S has 911 units available. Both parts meet identical electrical performance requirements and environmental operating specifications, making them functionally interchangeable for 25-position receptacle connector applications requiring 0.100" pitch through-hole mounting with gold-plated solder termination.

Frequently Asked Questions (FAQ)

Q: Can SSW-125-01-G-S replace SSW-125-21-G-S in existing designs?

A: Yes. Both parts are functionally equivalent receptacle connectors with identical electrical ratings, contact configurations, and mechanical dimensions. The difference in part number designation reflects internal series variation within the SSW-125 platform, not functional capability.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: 25-position receptacle configuration, 0.100" (2.54mm) mating pitch, through-hole solder termination, forked gold-plated contacts, 4.7A per contact current rating, and -55°C ~ 125°C operating temperature range.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status and UL94 V-0 flammability rating. No additional testing or qualification is required when substituting between these parts.

Q: What should be verified when switching between these connector models?

A: PCB footprint compatibility and mating connector specifications should be confirmed. Both parts use identical 0.100" pitch through-hole mounting and gold contact finish, ensuring compatibility with standard SSW series mating plugs and receptacles.
