Key Parameters

Substitute Part Grouping Explanation

Substitution of the JR21WP-10PC(71) is determined by strict equivalence across the following critical parameters:

• Series and Base Product Number: Both parts belong to the JR-W series with base product number JR21WP
• Connector Configuration: 10-position plug housing for male pins
• Shell Specifications: Shell size 21, aluminum alloy construction with chrome finish, black housing color
• Electrical and Mechanical Interface: Crimp contact type, 1.6mm contact size, keyed orientation, threaded fastening
• Environmental Rating: IP67 ingress protection, UL94 V-0 flammability rating
• Mounting and Features: Free-hanging inline mounting with backshell and coupling nut
• Operating Conditions: -25°C to 85°C temperature range

The substitute part JR21WP-10PC(31) maintains full equivalence across all these parameters, with the primary distinction being product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The JR21WP-10PC(31) is the direct active equivalent for the obsolete JR21WP-10PC(71). Both parts share identical electrical and mechanical specifications across all critical interface parameters. The JR21WP-10PC(31) offers the additional advantage of active product status, ensuring continued manufacturer support and supply availability.

The JR21WP-10PC(31) provides enhanced ingress protection rating of IP67/IP68 compared to the IP67 specification of the original part, representing an improvement in environmental sealing capability. The active part is RoHS compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

For new designs and field replacements, the JR21WP-10PC(31) is the appropriate selection. Existing installations using JR21WP-10PC(71) can transition to JR21WP-10PC(31) without modification to mating connectors or cable assemblies, as all mechanical and electrical interfaces remain unchanged.

Frequently Asked Questions (FAQ)

Q: Are JR21WP-10PC(71) and JR21WP-10PC(31) mechanically interchangeable?

A: Yes. Both parts maintain identical shell size (21), mounting configuration (free-hanging inline), fastening method (threaded coupling), and keyed orientation. Mating connectors and cable assemblies designed for JR21WP-10PC(71) are fully compatible with JR21WP-10PC(31).

Q: What is the difference between IP67 and IP67/IP68 ingress protection ratings?

A: The JR21WP-10PC(31) specifies IP67/IP68 rating, indicating compliance with both standards. IP67 provides dust-tight and waterproof protection under temporary immersion. IP68 extends protection to continuous immersion under specified pressure conditions. The enhanced rating does not affect mechanical or electrical compatibility.

Q: Can I use JR21WP-10PC(31) in applications originally designed for JR21WP-10PC(71)?

A: Yes. The JR21WP-10PC(31) maintains full electrical and mechanical equivalence across all specified parameters. The transition from obsolete to active status and the addition of RoHS compliance do not introduce any compatibility issues.

Q: What is the significance of RoHS compliance on the JR21WP-10PC(31)?

A: RoHS compliance indicates the part meets restrictions on hazardous substances in electrical and electronic equipment. This certification is required for distribution in many markets and reflects current manufacturing standards. The JR21WP-10PC(71) does not specify RoHS status.

Q: Are there any differences in contact specifications between these parts?

A: No. Both parts use identical crimp contact type, 1.6mm contact size, and circular contact shape. Contact specifications determine compatibility with mating pin sets and cable terminations.

Q: What packaging options are available?

A: The JR21WP-10PC(71) packaging is not specified in available documentation. The JR21WP-10PC(31) is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
