Engineering Selection Recommendations

The substitute part 982-015-020R121 is the appropriate selection for new designs and ongoing system support. This recommendation is based on the following factors:

Product Status: The substitute part maintains active product status, ensuring continued manufacturer support and availability, whereas the main part is classified as obsolete
Regulatory Compliance: The substitute part is ROHS3 compliant, meeting current environmental and regulatory requirements. The main part is RoHS non-compliant and does not meet modern compliance standards
Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters, including connector position count, shell size compatibility, cable exit angles, shielding configuration, and plating specifications
Inventory Availability: Both parts are available in stock, supporting immediate procurement requirements

For applications currently utilizing the 982-015-020-121, direct substitution with 982-015-020R121 is supported without design modification or re-qualification, provided that RoHS compliance requirements are met in the target application.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts are 15-position two-piece backshells with Shell Size A compatibility, supporting 15pos and HD26pos D-Sub configurations. The mechanical envelope, mating interface, and cable exit angles are identical.

Q: What is the primary difference between these parts?

A: The main difference is product status and regulatory compliance. The 982-015-020R121 is an active product with ROHS3 compliance, while the 982-015-020-121 is obsolete and RoHS non-compliant.

Q: Can I use the substitute part in existing assemblies designed for the main part?

A: Yes. The substitute part maintains identical specifications for all critical parameters including connector positions, shell size, cable exit angles, shielding, plating, and mating hardware. Direct substitution is supported without design changes.

Q: Does packaging differ between these parts?

A: The substitute part is supplied in bag packaging, while the main part packaging is not specified. This does not affect functional or mechanical compatibility.

Q: Are there any compliance considerations for substitution?

A: The substitute part is ROHS3 compliant, which may be required for applications subject to environmental regulations. The main part is RoHS non-compliant. Verify compliance requirements for your specific application.

Q: What cable types are supported?

A: Both parts support round cable types with 90° and 180° cable exit options.
