R22-8 Ring Terminal Connector 4 AWG 5/16 Stud - Equivalent & Substitute Parts

Part Overview

The R22-8 is a ring terminal connector manufactured by JST Sales America Inc., designed for 4 AWG wire gauge applications with a 5/16 inch stud connection. This non-insulated, crimp-style terminal features a D-shaped configuration with brazed seam construction. The part is currently listed as obsolete, making identification of active equivalent alternatives essential for procurement and design continuity. Substitute parts must maintain identical electrical and mechanical specifications to ensure proper circuit performance and mechanical reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R22-8 is determined by strict equivalence across the following critical parameters:

• Wire gauge capacity (4 AWG)
• Stud diameter (5/16 inch)
• Terminal geometry (D-shaped configuration)
• Crimp termination compatibility
• Non-insulated construction
• Physical dimensions (thickness, width, length)
• Brazed seam construction method

The substitute part 22-8 meets all these criteria and represents an active product alternative from the same manufacturer, differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 22-8 is the direct active equivalent for the obsolete R22-8 ring terminal connector. Both parts are manufactured by JST Sales America Inc. and maintain identical electrical and mechanical specifications across all critical parameters. The 22-8 is currently in active production status with confirmed inventory availability, making it the appropriate selection for new designs and component replacement applications.

Both parts satisfy RoHS compliance requirements. The 22-8 carries ROHS3 certification, representing current regulatory compliance standards. The negligible difference in overall length (0.01mm) is within standard manufacturing tolerance and does not affect functional performance or mechanical fit.

Packaging differs between the two parts: R22-8 is supplied in standard packaging, while 22-8 is available in bulk packaging. This distinction affects procurement logistics but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 22-8 be used as a direct replacement for the R22-8?

A: Yes. The 22-8 is electrically and mechanically equivalent to the R22-8 across all specified parameters. Both parts accommodate 4 AWG wire, feature identical 5/16 inch stud connections, and employ crimp termination with D-shaped geometry.

Q: What is the significance of the product status difference?

A: The R22-8 is obsolete, indicating it is no longer manufactured. The 22-8 is active and in current production. For new designs and ongoing procurement, the 22-8 should be specified to ensure supply chain continuity.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The R22-8 carries RoHS Compliant certification, while the 22-8 carries ROHS3 Compliant certification. ROHS3 represents the current regulatory standard and is fully backward compatible with RoHS requirements.

Q: Does packaging affect compatibility?

A: Packaging affects procurement and handling but not electrical or mechanical compatibility. The R22-8 standard packaging and 22-8 bulk packaging contain identical components. Selection between packaging options depends on order quantity and inventory management requirements.

Q: What wire gauges are compatible with these terminals?

A: Both the R22-8 and 22-8 are rated for 4 AWG wire gauge only. These terminals are not suitable for other wire gauges.

Q: What is the stud size specification?

A: Both terminals feature a 5/16 inch stud connection. This dimension is critical for proper mechanical fit with mating components and cannot be altered.
