Engineering Selection Recommendations

The TE Connectivity 1-1734531-2 and Sullins NPPN062FJFN-RC are both active-status alternatives to the obsolete 3M 950412-5002-AR. Both substitute parts maintain identical mechanical dimensions, pitch specifications, and thermal operating ranges. Both are UL94 V-0 rated and carry MSL 1 classification.

The TE Connectivity 1-1734531-2 is classified as the manufacturer-recommended substitute, maintaining receptacle connector type configuration. This part is RoHS3 compliant and carries ROHS3 certification status.

The Sullins NPPN062FJFN-RC is a header connector variant with identical mating pitch and row spacing. This part is RoHS3 compliant and carries REACH Unaffected status.

Selection between these alternatives depends on application requirements regarding connector type (receptacle versus header) and compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1734531-2 directly replace the 3M 950412-5002-AR?

A: Yes. Both connectors share identical 12-position, 0.079" (2.00mm) pitch configuration, through-hole right-angle mounting, and operating temperature range. Mechanical and electrical parameters are equivalent.

Q: What is the primary difference between the TE Connectivity and Sullins substitute options?

A: The TE Connectivity 1-1734531-2 is a receptacle connector, matching the original 3M part type. The Sullins NPPN062FJFN-RC is a header connector. Both maintain identical pitch, row spacing, and mounting orientation.
