Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 978-015-010-031 is determined by the following critical parameters that must remain constant:

• Number of Positions: 15 (electrical compatibility)
• Compatible Shell Size: A (mechanical fit)
• Compatible D-Sub Size: 15pos and HD26pos (connector interface compatibility)
• Cable Exit Angle: 180° (installation geometry)
• Cable Type: Round (cable accommodation)
• Shielding: Unshielded (EMI performance class)
• Material: Acrylonitrile Butadiene Styrene (ABS) (environmental resistance)
• Color: Gray (identification and consistency)
• Hardware Configuration: Assembly Hardware, Strain Relief with Mating Screws 4-40 (mechanical assembly)

The substitute part 978-015-010R031 maintains all these parameters while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 978-015-010R031 is the direct equivalent substitute for the obsolete 978-015-010-031. Both parts are manufactured by NorComp Inc. and maintain identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the following advantages:

• Active Product Status: The 978-015-010R031 is currently in active production, ensuring long-term availability and supply chain stability.
• Regulatory Compliance: The substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance status is relevant for applications subject to RoHS directives.
• Inventory Availability: The substitute part has higher inventory levels (1122 Pcs vs. 634 Pcs), supporting immediate procurement requirements.

Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are the 978-015-010-031 and 978-015-010R031 mechanically interchangeable?

A: Yes. Both parts are 15-position two-piece backshells with identical shell size (A), cable exit angle (180°), material composition (ABS), and hardware configuration (Mating Screws 4-40). They are direct mechanical substitutes.

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

A: The primary differences are product status and regulatory compliance. The 978-015-010-031 is obsolete and RoHS non-compliant. The 978-015-010R031 is an active product with ROHS3 compliance. All functional and mechanical parameters are identical.

Q: Can I use the 978-015-010R031 in applications currently using the 978-015-010-031?

A: Yes. The substitute part maintains all electrical and mechanical specifications required for compatibility with 15-position D-Sub connectors (15pos and HD26pos sizes) with 180° cable exit orientation.

Q: Does the packaging difference affect compatibility?

A: No. The packaging difference (unspecified for the original vs. Bulk for the substitute) does not affect the functional or mechanical performance of the backshell connector. Packaging is a logistics consideration only.

Q: Are there any compliance considerations when switching to the 978-015-010R031?

A: The substitute part achieves ROHS3 compliance, which may be beneficial for applications subject to RoHS directives. Both parts maintain identical REACH and ECCN classifications.
