• Color: Must be Gray
• Hardware Specification: Must include Assembly Hardware and Strain Relief with 4-40 Mating Screws

The substitute part 972-009-01SR031 satisfies all critical substitution parameters. Material composition differences (ABS versus Polyamide PA66) do not affect functional compatibility within the specified electrical and mechanical constraints of this product category.

Parameter Comparison

Engineering Selection Recommendations

The 972-009-01SR031 is the direct substitute for the obsolete 972-009-01S-031. Both parts maintain identical mechanical and electrical compatibility specifications for D-Sub connector applications.

The 972-009-01SR031 offers the following advantages:

• Active Product Status: Currently manufactured and supported by NorComp Inc., ensuring long-term availability and supply chain reliability.
• RoHS3 Compliance: Meets current regulatory requirements for restricted hazardous substances, whereas the original part is non-compliant.
• Improved Availability: 1600 units in stock compared to 950 units for the obsolete variant.
• Moisture Sensitivity Level: Rated MSL 1 (Unlimited), indicating superior environmental stability.

Material composition change from ABS to Polyamide PA66 does not compromise functional performance within the specified mechanical and electrical parameters of this backshell accessory.

Frequently Asked Questions (FAQ)

Q: Can the 972-009-01SR031 be used as a direct replacement for 972-009-01S-031 in existing designs?

A: Yes. Both parts share identical specifications for number of positions, shell size, cable exit angle, shielding configuration, and hardware requirements. The substitute part is mechanically and electrically compatible.

Q: What is the difference between the material compositions?

A: The original part uses Acrylonitrile Butadiene Styrene (ABS), while the substitute uses Polyamide PA66 (Nylon 6/6). Both materials provide the required mechanical properties for backshell applications. The material change does not affect connector compatibility or performance within the specified electrical and mechanical constraints.

Q: Why is the original part marked as obsolete?

A: The 972-009-01S-031 is no longer in active production. The 972-009-01SR031 represents the current active equivalent from NorComp Inc.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified in available data. The substitute part is supplied in Bulk packaging.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and supply chain consideration, not a functional compatibility parameter. The substitute part's ROHS3 compliance ensures compliance with current environmental regulations.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: The substitute part's MSL 1 (Unlimited) rating indicates no moisture sensitivity restrictions during storage or handling, providing superior environmental stability compared to the original part's non-applicable MSL designation.
