Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-104-03-S-D-RA is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle, 8-position, 2-row arrangement
• Pitch & Spacing: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Electrical Performance: 4.7A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, -55°C to 125°C operating range
• Contact Materials & Finish: Gold mating surface (30.0µin thickness), tin post finish, phosphor bronze contact material, forked contact type

The substitute part SSW-104-03-SM-D-RA maintains identical specifications across all these parameters, confirming direct substitution capability.

Frequently Asked Questions (FAQ)

Q: Can SSW-104-03-SM-D-RA be used as a direct replacement for SSW-104-03-S-D-RA?

A: Yes. Both parts are identical across all electrical and mechanical parameters, including connector type, position count, pitch, mounting configuration, contact materials, finish specifications, current rating, and operating temperature range. Direct substitution is supported without design modification.

Q: What are the key differences between these part numbers?

A: The part numbers differ only in the third position designator (S versus SM). All functional, electrical, and mechanical specifications remain identical. The difference reflects internal Samtec manufacturing or packaging designation only.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across -55°C to 125°C and carry UL94 V-0 flammability certification, supporting industrial and demanding thermal environments.

Q: Do these connectors support the same current requirements?

A: Yes. Both parts are rated for 4.7A per contact, supporting identical power distribution requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-104-03-S-D-RA and SSW-104-03-SM-D-RA are ROHS3 compliant, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the mating pitch for these connectors?

A: Both parts feature 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing in a 2-row, 8-position configuration.
