Engineering Selection Recommendations
All three parts—SSW-111-21-S-S, SSW-111-01-SM-S, and SSW-111-01-S-S—are active products with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences. SSW-111-01-S-S currently has the highest inventory level at 1048 pieces, followed by SSW-111-21-S-S at 897 pieces and SSW-111-01-SM-S at 795 pieces. All parts meet UL94 V-0 flammability requirements and are suitable for applications requiring 4.7A per contact capacity within the -55°C to 125°C operating range.
Frequently Asked Questions (FAQ)
Q: Can SSW-111-01-SM-S and SSW-111-01-S-S be used interchangeably with SSW-111-21-S-S?
A: Yes. All three parts share identical electrical and mechanical parameters, including 11-position configuration, 0.100" pitch, gold-plated mating contacts, tin-plated posts, and 4.7A per contact rating. They are functionally equivalent within the SSW series.
Q: What determines substitutability for SSW series 11-position receptacles?
A: Substitutability is determined by maintaining the following parameters: 11-position count, 0.100" (2.54mm) mating pitch, through-hole solder termination, gold contact finish on mating surfaces, tin finish on posts, Liquid Crystal Polymer insulation, UL94 V-0 rating, and -55°C to 125°C operating temperature range.
Q: Are there any compliance differences between these substitute parts?
A: No. All three parts are ROHS3 compliant, carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications, and share identical material flammability ratings.
Q: How do the part numbers differ if the specifications are identical?
A: Part number variations within the SSW series reflect internal Samtec designations. The differences in the part number suffix do not indicate functional or electrical differences for these three 11-position receptacle connectors.
Q: Which part should be selected for new designs?
A: Any of the three parts is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times, as all parts are active products with equivalent performance characteristics.
