Substitute Part Grouping Explanation

The substitute part 976-009-010R031 qualifies as a direct equivalent based on the following critical parameters:

• Number of Positions: Both parts specify 9 positions
• Compatible Shell Size: Both support Shell Size E
• Compatible D-Sub Size: Both support 9pos and HD15pos configurations
• Cable Exit Angle: Both feature 180° cable exit
• Cable Type: Both accommodate flat cable
• Shielding Configuration: Both are unshielded
• Primary Material: Both use Acrylonitrile Butadiene Styrene (ABS)
• Color: Both are gray
• Hardware Specification: Both include assembly hardware, strain relief, and 4-40 mating screws
• Accessory Type: Both are two-piece backshell connectors

The primary distinction is product status: the original part is obsolete, while the substitute is active in production.

Parameter Comparison

Engineering Selection Recommendations

The 976-009-010R031 is the direct functional equivalent for the obsolete 976-009-010-031. All mechanical and electrical parameters are identical. The substitute part offers the following advantages:

• Active Product Status: The substitute is in active production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The substitute achieves ROHS3 compliance, whereas the original is non-compliant. This is significant for applications subject to RoHS regulations.
• Moisture Handling: The substitute specifies MSL 1 (Unlimited), providing superior moisture tolerance compared to the original's unspecified rating.

Selection of the 976-009-010R031 is appropriate for all applications previously using the 976-009-010-031, with the added benefit of improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the 976-009-010-031 and 976-009-010R031 mechanically interchangeable?

A: Yes. Both parts are 9-position two-piece backshells with identical shell size (E), cable exit angle (180°), material (ABS), and hardware specifications (4-40 mating screws). They mount identically to D-Sub 9-position and HD15-position connectors.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 976-009-010-031 is obsolete and RoHS non-compliant. The 976-009-010R031 is active in production and ROHS3 compliant. All functional parameters are identical.

Q: Can I use the 976-009-010R031 as a direct replacement in existing designs?

A: Yes. The substitute part maintains all electrical and mechanical specifications of the original. The improved RoHS compliance and active production status make it the preferred choice for new procurement and system updates.

Q: What cable types are compatible with these backshells?

A: Both parts are specified for flat cable with 180° exit angle. This configuration is standard for D-Sub 9-position and HD15-position applications.

Q: Are there any packaging differences between these parts?

A: The substitute part is supplied in bulk packaging. Packaging format does not affect mechanical or electrical compatibility.
