Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JR16RK-7S is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle with female sockets in 7-position configuration
• Shell Size: Must maintain 16 shell size - insert specification for mechanical compatibility
• Mounting Configuration: Must support panel mount with flange and threaded fastening
• Termination Method: Must utilize solder cup termination
• Keyed Orientation: Must maintain keyed orientation for polarization
• Current & Voltage Ratings: Must support minimum 10A current rating
• Operating Temperature Range: Must maintain -25°C ~ 85°C operational envelope
• Material & Finish Compatibility: Must use copper alloy contacts with appropriate finish specifications

The JR16WR-7S(31) meets these substitution criteria as an active production alternative within the Hirose JR series family.

• Compliance Alignment: Both parts maintain UL94 V-0 flammability rating and meet RoHS requirements. The substitute achieves ROHS3 compliance, representing current regulatory standards.
• Mechanical & Electrical Compatibility: The substitute maintains identical connector type, position count, shell size, mounting configuration, termination method, and current rating specifications.
• Enhanced Environmental Protection: The JR16WR-7S(31) provides IP67/IP68 ingress protection rating, offering superior environmental sealing compared to the main part.
• Operational Equivalence: Both parts support identical operating temperature range and contact specifications, ensuring functional interchangeability in solder cup termination applications.

Frequently Asked Questions (FAQ)

Q: Can JR16WR-7S(31) be used as a direct replacement for JR16RK-7S in existing designs?

A: Yes. Both connectors share identical connector type, position count, shell size, mounting configuration, termination method, fastening type, and orientation. The substitute maintains equivalent current rating, operating temperature range, and contact specifications. The primary design difference is the enhanced ingress protection rating of the substitute part.

Q: What are the differences in shell finish between these parts?

A: The JR16RK-7S features nickel finish with silver color. The JR16WR-7S(31) features black chromium finish with black color. Both finishes provide corrosion resistance appropriate for their respective applications.

Q: Are there voltage rating differences between the main part and substitute?

A: Yes. The JR16RK-7S is rated for 250VAC and 350VDC. The JR16WR-7S(31) is rated for 100VAC and 140VDC. Applications requiring the higher voltage specifications of the main part must verify substitute compatibility with circuit requirements.

Q: What is the significance of the IP67/IP68 rating on the substitute part?

A: The JR16WR-7S(31) provides dust-tight and waterproof environmental sealing. This enhanced ingress protection is suitable for automotive, industrial, and telecommunications applications where environmental exposure is a design consideration.

Q: How do the RoHS compliance levels differ?

A: The JR16RK-7S meets RoHS Compliant specification. The JR16WR-7S(31) meets ROHS3 Compliant specification, representing current regulatory requirements. Both parts are compliant with applicable RoHS directives.

Q: Is the cable opening specification identical between parts?

A: The JR16RK-7S specifies cable opening as 0.783" (19.90mm). The JR16WR-7S(31) does not provide a cable opening specification in the available data. Cable opening compatibility must be verified for specific backshell or cable assembly applications.
