Substitute Part Grouping Explanation

Substitution eligibility for the 970-015-020-121 is determined by strict equivalence across the following critical parameters:

• Number of Positions: 15
• Compatible Shell Size: A
• Compatible D-Sub Size: 15pos and HD26pos
• Cable Exit Angle: 180°
• Shielding Configuration: Shielded
• Accessory Type: Two Piece Backshell
• Cable Type: Round
• Plating Specification: Nickel over Copper
• Mating Hardware: 4-40 Screws

The substitute part 970-015-020R121 maintains complete electrical and mechanical equivalence across all specified parameters, with the primary distinction being active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The 970-015-020R121 serves as the direct active equivalent to the obsolete 970-015-020-121. Selection of the substitute part is supported by:

• Complete mechanical and electrical parameter equivalence across all specified dimensions and configurations
• Active product status ensuring ongoing availability and supply chain continuity
• RoHS3 compliance, meeting current environmental and regulatory requirements
• Identical plating, material composition, and hardware specifications
• Same series designation (970) with ARMOR variant designation indicating enhanced specification compliance

For applications requiring the 970-015-020-121, transition to 970-015-020R121 maintains full functional compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Are the 970-015-020-121 and 970-015-020R121 mechanically interchangeable?

A: Yes. Both parts maintain identical specifications for shell size, position count, cable exit angle, shielding configuration, and mating hardware. Direct substitution is supported without mechanical redesign.

Q: What is the significance of the "R" designation in 970-015-020R121?

A: The "R" suffix indicates a revised specification version within the NorComp 970 series. This revision includes RoHS3 compliance and active product status, distinguishing it from the obsolete original part number.

Q: Does the RoHS3 compliance of 970-015-020R121 affect compatibility with existing designs?

A: No. RoHS3 compliance represents an improvement in environmental and regulatory adherence. The part maintains full electrical and mechanical compatibility with applications designed for the original 970-015-020-121.

Q: Are there packaging differences between these parts?

A: The 970-015-020-121 packaging is not specified in available documentation. The 970-015-020R121 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: What is the cable type compatibility for both parts?

A: Both parts are specified for round cable type with 180° exit angle. This configuration applies uniformly across the 970-015-020-121 and 970-015-020R121 variants.

Q: Can these backshells be used with both 15-position and HD26-position D-Sub connectors?

A: Yes. Both parts specify compatibility with 15pos and HD26pos D-Sub sizes, providing flexibility across multiple connector configurations within the compatible shell size A specification.
