Engineering Selection Recommendations

Both SSM-110-S-DV-BE-A-M and SSM-110-S-DV-BE-A-K are Active products with full ROHS3 compliance and MSL 1 rating, indicating unrestricted moisture handling and storage. Selection between these parts may be based on inventory availability: SSM-110-S-DV-BE-A-M has 1059 pieces in stock, while SSM-110-S-DV-BE-A-K has 845 pieces available. From an engineering perspective, both parts are electrically and mechanically equivalent for board-to-board or cable applications requiring 20-position surface mount receptacle connectors with 0.100" pitch spacing and gold contact finish.

Frequently Asked Questions (FAQ)

Q: Are SSM-110-S-DV-BE-A-M and SSM-110-S-DV-BE-A-K directly interchangeable?

A: Yes. Both parts share identical electrical ratings (5.2A per contact, 405VAC/572VDC), mechanical configuration (20-position, 2-row, 0.100" pitch), contact system (gold-plated female socket), and environmental specifications (-55°C to 125°C operating range, ROHS3 compliance, MSL 1). They are direct substitutes within the Tiger Claw™ SSM series.

Q: What determines substitution eligibility for this connector family?

A: Substitution is based on matching all critical parameters: connector type and entry configuration, position count and row layout, mating pitch and spacing, contact type and finish specifications, current and voltage ratings, operating temperature range, insulation material, and compliance certifications. Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Can these connectors be used in applications requiring different pitch spacing?

A: No. Both SSM-110-S-DV-BE-A-M and SSM-110-S-DV-BE-A-K are fixed at 0.100" (2.54mm) mating pitch and row spacing. Applications requiring different spacing require alternative connector families.

Q: What is the significance of the gold contact finish thickness specification?

A: The 30.0µin (0.76µm) gold plating thickness on mating contacts ensures consistent contact resistance, durability against mating cycles, and corrosion resistance. This specification must match for electrical performance equivalence.

Q: Are there packaging differences between these substitute parts?

A: Both parts are supplied in Tube packaging. No packaging variation exists between SSM-110-S-DV-BE-A-M and SSM-110-S-DV-BE-A-K.
