Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JR21WCC-6(71) is determined by strict equivalence across the following critical parameters:

• Shell Size - Insert: 21
• Thread Size: M24x0.75
• Cable Opening: 0.236" (6.00mm)
• Cable Exit: 180°
• Ingress Protection: IP67
• Series Compatibility: JR-W Series Plug

The JR21WCC-6(31) meets all substitution criteria. Both parts share identical mechanical interfaces, electrical performance characteristics, and environmental ratings. The primary distinction is product status: JR21WCC-6(71) is obsolete, while JR21WCC-6(31) maintains active production status with current availability.

Parameter Comparison

Engineering Selection Recommendations

The JR21WCC-6(31) is the direct functional equivalent for the obsolete JR21WCC-6(71). Selection of JR21WCC-6(31) is supported by:

• Identical mechanical interface specifications (M24x0.75 thread, 21 shell size, 6.00mm cable opening)
• Matching environmental performance (IP67 ingress protection)
• Active production status with confirmed inventory availability (899 pcs in stock)
• RoHS compliance certification on the substitute part
• Consistent material composition and plating specifications

For applications currently using JR21WCC-6(71), direct substitution with JR21WCC-6(31) requires no design modification or system reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can JR21WCC-6(31) be used as a direct replacement for JR21WCC-6(71)?

A: Yes. Both parts share identical specifications for shell size, thread size, cable opening, cable exit angle, and ingress protection rating. No mechanical or electrical modifications are required.

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

A: The primary difference is product status. JR21WCC-6(71) is obsolete, while JR21WCC-6(31) is in active production. JR21WCC-6(31) includes RoHS compliance certification. Material composition differs slightly: JR21WCC-6(71) uses Aluminum Alloy, Brass, and Zinc Alloy, while JR21WCC-6(31) uses Brass. Both maintain equivalent functional performance.

Q: Are there packaging differences between these parts?

A: JR21WCC-6(71) packaging is not specified. JR21WCC-6(31) is supplied in bulk packaging. Both include identical component sets: 1 cable clamp, 1 gasket, 2 screws, and 1 washer per unit.

Q: What is the cable opening specification?

A: Both parts accommodate a 6.00mm (0.236") cable opening with M24x0.75 threaded connection and 180° cable exit configuration.

Q: Is RoHS compliance required for my application?

A: JR21WCC-6(31) is RoHS compliant. JR21WCC-6(71) RoHS status is not specified. If RoHS compliance is a system requirement, JR21WCC-6(31) is the appropriate selection.
