Substitute Part Grouping Explanation

Substitute parts for the SSW-115-21-S-S are identified within the Samtec SSW series based on matching the following critical parameters:

15-position receptacle configuration
0.100" (2.54mm) mating pitch
Forked contact type
Through-hole solder termination
Gold mating contact finish with 30.0µin thickness
Tin post finish
4.7A per contact current rating

Engineering Selection Recommendations

All three parts—SSW-115-21-S-S, SSW-115-01-S-S, and SSW-115-01-SM-S—are active production components with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Inventory availability: SSW-115-01-SM-S offers the highest stock level at 1090 units, followed by SSW-115-21-S-S at 1054 units, and SSW-115-01-S-S at 784 units.
Design compatibility: All parts share identical electrical and mechanical parameters and are functionally interchangeable in applications requiring 15-position, 0.100" pitch receptacle connectors with gold mating contacts and 4.7A per contact rating.
Supply chain considerations: Multiple active sources within the SSW series provide redundancy for production continuity.

Frequently Asked Questions (FAQ)

Q: Are SSW-115-01-S-S and SSW-115-01-SM-S direct substitutes for SSW-115-21-S-S?

A: Yes. All three parts maintain identical electrical specifications (4.7A per contact, -55°C to 125°C operating range), mechanical configuration (15 positions, 0.100" pitch, through-hole solder termination), contact finishes (gold mating, tin post), and compliance certifications (ROHS3, UL94 V-0). They are functionally equivalent for standard board-to-board and cable applications.

Q: What determines substitutability between these connector models?

A: Substitutability is determined by matching: connector type (receptacle), position count (15), mating pitch (0.100"), contact type (forked), mounting method (through-hole), termination type (solder), contact finish specifications, current rating, temperature range, insulation material, and flammability rating. All three parts match on these parameters.

Q: Can I use these connectors interchangeably in my PCB design?

A: Yes, provided your design accommodates the through-hole mounting footprint and solder termination. The identical pitch, position count, and contact specifications ensure mechanical and electrical compatibility across all three part numbers.

Q: What is the difference between SSW-115-21-S-S and SSW-115-01-S-S?

A: Both parts are functionally identical in electrical and mechanical performance. The designation difference reflects internal design variations within the SSW series that do not affect application compatibility.

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

A: No. All three parts carry identical certifications: ROHS3 compliance and UL94 V-0 flammability rating. They meet the same regulatory and safety standards.
