Substitute Part Grouping Explanation

The NorComp 983-015-020R121 qualifies as a direct substitute for the 983-015-020-121 based on the following critical parameters:

• Number of Positions: Both parts maintain 15-position configuration
• Accessory Type: Both are two-piece backshell connectors
• Compatible Shell Size: Both support Shell Size A
• Compatible D-Sub Size: Both support 15pos and HD26pos configurations
• Cable Exit Angle: Both feature 180° cable exit
• Shielding Configuration: Both provide shielded designs
• Cable Type: Both accommodate round cable
• Plating Specification: Both use nickel over copper
• Hardware: Both include strain relief with 4-40 mating screws
• Color: Both are silver

The primary distinction is product status: the 983-015-020-121 is obsolete, while the 983-015-020R121 is active. The substitute part shares identical electrical and mechanical parameters, differing only in packaging (bulk) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The NorComp 983-015-020R121 is the appropriate selection for applications currently specified with the 983-015-020-121. Both parts maintain identical electrical and mechanical compatibility across all critical parameters. The 983-015-020R121 offers the additional advantage of active product status, ensuring continued availability and supply chain reliability.

For applications subject to RoHS3 compliance requirements, the 983-015-020R121 is mandatory, as it meets ROHS3 standards while the original part does not. Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Are the 983-015-020-121 and 983-015-020R121 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including shell size A compatibility, 15-position configuration, 180° cable exit, and 4-40 mating screw hardware. Physical installation and mating characteristics are identical.

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

A: The primary differences are product status (obsolete versus active) and RoHS compliance. The 983-015-020R121 is ROHS3 compliant, while the 983-015-020-121 is not. The substitute part is available in bulk packaging.

Q: Can I use the 983-015-020R121 in place of the 983-015-020-121 in existing designs?

A: Yes. The substitute part maintains all electrical and mechanical parameters required for direct substitution. No design modifications are necessary.

Q: Does the packaging difference affect compatibility?

A: No. Packaging format (bulk versus other configurations) does not affect the connector's electrical or mechanical performance. It impacts only procurement and handling procedures.

Q: Are both parts suitable for shielded D-Sub applications?

A: Yes. Both parts provide shielded configurations and are compatible with 15-position and HD26-position D-Sub connectors with Shell Size A.
