972-015-01S-031 D-Sub Backshell Connector Equivalent & Substitute Parts
Part Overview
The 972-015-01S-031 is a 15-position hinged backshell connector manufactured by NorComp Inc., designed for D-Sub applications with 180° cable exit orientation. This component is classified as an accessory backshell for D-Sub connectors and is currently listed as obsolete. Due to its obsolete status, identifying functionally equivalent active production alternatives is necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation
Substitution eligibility for the 972-015-01S-031 is determined by the following critical parameters:
- Accessory Type: Must be Hinged Backshell
- Number of Positions: Must be 15
- Compatible Shell Size: Must be A
- Compatible D-Sub Size: Must support 15pos and HD26pos
- Cable Exit Angle: Must be 180°
- Shielding Configuration: Must be Unshielded
- Hardware: Must include Assembly Hardware and Strain Relief
- Mating Screws: Must be 4-40
The substitute part 972-015-01SR031 meets all these criteria. The primary difference is the material composition (Polyamide PA66/Nylon 6/6 versus ABS) and the product status transition from obsolete to active production, along with improved RoHS compliance.

Engineering Selection Recommendations
The 972-015-01SR031 is the direct substitute for the obsolete 972-015-01S-031. Both components share identical functional specifications for D-Sub backshell applications, including position count, shell size compatibility, cable exit orientation, and hardware configuration.
The 972-015-01SR031 offers the following advantages:
- Active Production Status: Currently manufactured and available in production quantities (1058 Pcs in stock versus 956 Pcs for the obsolete part)
- Enhanced Compliance: ROHS3 compliant, addressing regulatory requirements for new designs and procurement
- Material Upgrade: Polyamide PA66/Nylon 6/6 provides improved mechanical properties and environmental resistance compared to ABS
- Standardized Packaging: Available in bulk packaging format
For applications requiring the 972-015-01S-031, the 972-015-01SR031 provides direct functional equivalence with improved compliance and availability characteristics.
Frequently Asked Questions (FAQ)
Q: Can the 972-015-01SR031 be used as a direct replacement for the 972-015-01S-031?
A: Yes. Both components are 15-position hinged backshells with identical mechanical and electrical specifications, including shell size A compatibility, 180° cable exit, unshielded configuration, and 4-40 mating screws. The substitute part is actively manufactured and available.
Q: What is the material difference between these two parts?
A: The 972-015-01S-031 uses Acrylonitrile Butadiene Styrene (ABS), while the 972-015-01SR031 uses Polyamide PA66/Nylon 6/6. Both materials are plastic-based and provide the required mechanical properties for backshell applications. The PA66/Nylon 6/6 material in the substitute part offers enhanced environmental resistance.
Q: Are there any compatibility concerns when switching from the obsolete to the active part?
A: No compatibility concerns exist. Both parts maintain identical dimensional and functional specifications for D-Sub 15-position and HD26-position connector compatibility. The cable exit angle, shielding configuration, and hardware specifications are identical.
Q: What is the significance of the RoHS compliance difference?
A: The 972-015-01S-031 is RoHS non-compliant, while the 972-015-01SR031 is ROHS3 compliant. For new designs and procurement in regulated markets, the ROHS3-compliant substitute part is required to meet environmental and regulatory standards.
Q: Are both parts available in the same packaging format?
A: The 972-015-01S-031 packaging information is not specified. The 972-015-01SR031 is available in bulk packaging. Confirm packaging requirements with your procurement specifications.
Q: Do both parts have the same export classification?
A: Yes. Both components are classified under ECCN EAR99 and HTSUS 8538.90.8180, indicating identical export control and tariff classification.
