Frequently Asked Questions (FAQ)

Q: Are SSW-125-23-S-D and SSW-125-03-SM-D fully interchangeable?

A: Yes. Both connectors share identical specifications across all critical parameters: 50-position configuration, 0.100" pitch, through-hole solder termination, gold-plated contacts, 4.7A current rating, and -55°C to 125°C operating range. They are direct substitutes within the SSW-125 series.

Q: What determines substitution eligibility for this connector type?

A: Substitution is based on matching connector type (receptacle), position count (50), pitch spacing (0.100"), row configuration (2 rows), mounting method (through-hole), termination type (solder), contact finish (gold at 30.0µin), current rating (4.7A), operating temperature range (-55°C to 125°C), and material certifications (UL94 V-0, ROHS3).

Q: Can I use these connectors in high-temperature applications?

A: Both connectors are rated for -55°C to 125°C operation. Applications requiring operation beyond this range require alternative connector selection.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in bulk packaging. No packaging format differences exist between SSW-125-23-S-D and SSW-125-03-SM-D.

Q: What is the difference between the part numbers SSW-125-23-S-D and SSW-125-03-SM-D?

A: The part numbers reflect internal Samtec designation variants within the SSW-125 base series. All specified electrical and mechanical parameters remain identical, making them functionally equivalent for connector applications.
