R18-6L Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The R18-6L is a ring terminal connector manufactured by 3M, designed for 18-22 AWG wire applications with a #6 stud circular configuration. This non-insulated crimp terminal features a butted seam construction and tin-plated copper contact material. The product is currently obsolete, making identification of suitable substitutes necessary for ongoing maintenance and repair applications where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

The 3M 94725 is identified as a manufacturer-recommended substitute for the R18-6L. Substitution eligibility is determined by the following critical parameters that must remain consistent:

• Terminal Type: Circular configuration maintained
• Stud/Tab Size: #6 stud specification preserved
• Wire Gauge: 18-22 AWG compatibility maintained
• Termination Method: Crimp connection type preserved
• Contact Material: Copper, ETP maintained
• Contact Finish: Tin plating maintained
• Mounting Type: Free Hanging (In-Line) configuration preserved

The 94725 substitute differs in insulation status (insulated versus non-insulated), overall length, and product status (active versus obsolete), but maintains all core electrical and mechanical compatibility parameters for the 18-22 AWG #6 stud ring terminal application.

Parameter Comparison

Engineering Selection Recommendations

The 3M 94725 is the manufacturer-recommended substitute for the obsolete R18-6L. Both components maintain identical electrical and mechanical specifications for 18-22 AWG #6 stud ring terminal applications, including contact material, finish, and crimp termination method.

The primary distinction is that the 94725 is an insulated variant with vinyl insulation and red color coding, whereas the R18-6L is non-insulated. The 94725 also features a slightly longer overall length (0.800" versus 0.600") and is currently in active production status with RoHS compliance certification.

Selection between these components should be based on application requirements regarding insulation necessity and available space constraints. Both components satisfy REACH and EAR99 compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 94725 directly replace the R18-6L in all applications?

A: The 94725 maintains all critical electrical and mechanical parameters for 18-22 AWG #6 stud ring terminal connections. However, the addition of vinyl insulation and increased overall length (0.800" versus 0.600") may affect fit in space-constrained applications. Verify mounting clearance and insulation requirements for your specific application.

Q: What is the significance of the insulation difference between these parts?

A: The R18-6L is non-insulated, while the 94725 includes vinyl insulation with red color coding. Insulation provides electrical isolation and environmental protection. Application requirements determine whether insulation is necessary or acceptable.

Q: Why is the R18-6L listed as obsolete?

A: The R18-6L has been discontinued by the manufacturer. The 94725 represents the current active production alternative within the Highland™ series for this terminal configuration and wire gauge specification.

Q: Are there any compliance differences between these components?

A: Both components are REACH Unaffected and classified as EAR99. The 94725 carries RoHS Compliant certification, while the R18-6L does not list this certification. Verify compliance requirements for your application.

Q: What packaging options are available?

A: The R18-6L was supplied in standard packaging. The 94725 is available in bulk packaging with a minimum order unit of 1 piece.
