Key Parameters

Substitute Part Grouping Explanation

The 970-037-030R121 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters: 37-position configuration, shell size C, 180° cable exit angle, shielded construction, identical material composition (metal with zinc), nickel over copper plating, and 4-40 mating screws. Both parts are manufactured by NorComp Inc. and maintain compatibility with 37pos and HD62pos D-Sub sizes. The substitution is valid across all mechanical and electrical interfaces.

Parameter Comparison

Engineering Selection Recommendations

The 970-037-030R121 is the appropriate selection for new designs and ongoing procurement. This part maintains full mechanical and electrical compatibility with the obsolete 970-037-030-121 while offering active product status and ROHS3 compliance. The substitute part is manufactured by the same supplier and carries identical electrical specifications, material composition, and mechanical interfaces. For applications subject to RoHS requirements, the 970-037-030R121 satisfies regulatory compliance where the original part does not.

Frequently Asked Questions (FAQ)

Q: Are the 970-037-030-121 and 970-037-030R121 mechanically interchangeable?
