- Pitch spacing (0.100" / 2.54mm)
- Number of rows (2)
- Row spacing (0.100" / 2.54mm)
- Mounting method (Through Hole)
- Termination type (Solder)
- Contact finish on mating surface (Gold, 30.0µin thickness)
- Current rating (4.7A per contact)
- Operating temperature range (-55°C ~ 125°C)
- Flammability rating (UL94 V-0)
- RoHS compliance (ROHS3)
The identified substitute part SSW-112-02-S-D meets all these criteria, confirming full electrical and mechanical interchangeability within the SSW series.

Engineering Selection Recommendations
Both the SSW-112-22-S-D and SSW-112-02-S-D are active production components from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The substitute part SSW-112-02-S-D provides equivalent performance with no functional or compatibility limitations.
Frequently Asked Questions (FAQ)
Q: Are SSW-112-22-S-D and SSW-112-02-S-D fully interchangeable?
A: Yes. Both connectors share identical electrical and mechanical parameters including connector type, position count, pitch spacing, current rating, operating temperature range, and contact finishes. Direct substitution is supported without design modifications.
Q: What determines substitution eligibility for SSW series connectors?
A: Substitution requires matching connector type (receptacle), position count (24), pitch spacing (0.100"), row configuration (2 rows at 0.100" spacing), mounting method (through hole), termination type (solder), contact finish specifications (gold mating, tin post), current rating (4.7A), operating temperature range (-55°C to 125°C), and compliance certifications (UL94 V-0, ROHS3).
Q: Can these connectors be used in high-temperature applications?
A: Both parts are rated for continuous operation from -55°C to 125°C. Applications requiring operation outside this range require alternative connector selection.
Q: What is the current handling capacity per contact?
A: Each contact is rated for 4.7A maximum current. Total circuit current must account for the number of active contacts in the application.
Q: Are both parts RoHS compliant?
A: Yes. Both SSW-112-22-S-D and SSW-112-02-S-D are ROHS3 compliant and suitable for applications with RoHS requirements.
