972-037-01S-031 D-Sub Backshell Connector Equivalent & Substitute Parts

Part Overview

The 972-037-01S-031 is a 37-position hinged backshell connector manufactured by NorComp Inc., designed for D-Sub applications with a 180° cable exit configuration. This component is classified as an accessory backshell for 37-position and HD62-position D-Sub connectors, featuring unshielded construction with gray ABS plastic housing.

The 972-037-01S-031 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain supply chain continuity and ensure design compatibility in applications where this connector is currently specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 972-037-01S-031 is determined by the following critical parameters:

• Number of Positions: Must be 37
• Compatible Shell Size: Must be C
• Compatible D-Sub Size: Must support 37pos and HD62pos
• Cable Exit Angle: Must be 180°
• Shielding Configuration: Must be Unshielded
• Color: Must be Gray
• Hardware: Must include Assembly Hardware and Strain Relief with 4-40 Mating Screws
• Accessory Type: Must be Hinged Backshell

The substitute part 972-037-01SR031 meets all critical electrical and mechanical parameters required for direct substitution. While the primary material differs (Polyamide PA66 Nylon 6/6 versus ABS plastic), both materials satisfy the functional requirements for this backshell application and maintain compatibility with all specified D-Sub connector sizes and configurations.

Parameter Comparison

Engineering Selection Recommendations

The 972-037-01SR031 is the direct substitute for the obsolete 972-037-01S-031. Both components share identical electrical and mechanical specifications for D-Sub backshell applications.

The primary distinction between these parts is product status and regulatory compliance. The 972-037-01SR031 maintains active production status and achieves ROHS3 compliance, whereas the 972-037-01S-031 is obsolete and RoHS non-compliant. For new designs or applications requiring regulatory compliance with current environmental standards, the 972-037-01SR031 is the appropriate selection.

The material change from ABS to Polyamide PA66 (Nylon 6/6) in the substitute part does not affect functional compatibility. Both materials provide the mechanical strength and dimensional stability required for hinged backshell operation with 37-position D-Sub connectors.

Frequently Asked Questions (FAQ)

Q: Can the 972-037-01SR031 be used as a direct replacement for the 972-037-01S-031?

A: Yes. Both parts are 37-position hinged backshells with identical cable exit angles (180°), compatible shell sizes (C), and D-Sub compatibility (37pos and HD62pos). All mechanical and electrical parameters match.

Q: What is the difference in material between these two parts?

A: The 972-037-01S-031 uses Acrylonitrile Butadiene Styrene (ABS) plastic, while the 972-037-01SR031 uses Polyamide PA66 (Nylon 6/6). Both materials meet the functional requirements for this backshell application.

Q: Why is the 972-037-01S-031 listed as obsolete?

A: The 972-037-01S-031 has reached end-of-life status. The 972-037-01SR031 is the active production equivalent and should be used for new applications and replenishment orders.

Q: Does the 972-037-01SR031 meet current regulatory requirements?

A: Yes. The 972-037-01SR031 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The 972-037-01S-031 is RoHS non-compliant.

Q: Are there packaging differences between these parts?

A: The 972-037-01S-031 packaging information is not specified. The 972-037-01SR031 is supplied in bulk packaging.

Q: What is the base product number for the 972-037-01SR031?

A: The base product number is 972-037, which identifies the product family for 37-position D-Sub backshells within the NorComp Inc. series 972 connector line.
