3M 94737 Ring Terminal Connector - Equivalent & Substitute Parts

Part Overview

The 3M 94737 is an insulated ring terminal connector designed for 14-16 AWG wire gauges with a #6 stud connection. This circular terminal features crimp termination and is constructed from copper with tin finish. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for ring terminal applications requiring 6-stud circular connections in the 14-16 AWG range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 94737 is determined by strict equivalence across the following critical parameters:

• Terminal Type: Circular
• Stud/Tab Size: 6 Stud
• Wire Gauge Range: 14-16 AWG
• Termination Method: Crimp
• Insulation: Insulated
• Contact Material: Copper-based
• Contact Finish: Tin

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications requiring ring terminal connectors with #6 stud connections for 14-16 AWG wire.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as active products, providing continuity for applications currently using the obsolete 3M 94737.

The 3M 94736 maintains the same manufacturer lineage and series designation (Highland™), with identical electrical specifications and thickness. The primary difference is insulation material composition (vinyl versus nylon) and outer dimensional variations. This part carries RoHS Compliant certification.

The Panduit PN14-6RN-C (Pan-Term® series) provides an alternative from a different manufacturer with equivalent core specifications. This part is ROHS3 Compliant and maintains nylon insulation material consistent with the original 3M 94737. Dimensional variations exist in overall length and insulation diameter range.

Selection between substitutes should be based on application-specific requirements regarding insulation material compatibility, dimensional constraints, and compliance certifications applicable to the end-use environment.

Frequently Asked Questions (FAQ)

Q: Can the 3M 94736 directly replace the 3M 94737 in all applications?

A: Both parts share identical wire gauge (14-16 AWG), stud size (#6), termination method (crimp), and contact specifications (copper with tin finish). The insulation material differs (vinyl versus nylon), which may affect performance in specific environmental conditions. Verify insulation material compatibility with your application requirements.

Q: What are the dimensional differences between substitute parts?

A: The 3M 94736 has a width of 0.330" (8.38mm) and length of 0.900" (22.86mm). The Panduit PN14-6RN-C has a width of 0.250" (6.35mm) and length of 0.760" (19.30mm). The original 3M 94737 measures 0.250" (6.35mm) width and 0.810" (20.57mm) length. Verify dimensional compatibility with your mounting and assembly requirements.

Q: Are there compliance differences between the substitute parts?

A: The 3M 94736 is RoHS Compliant. The Panduit PN14-6RN-C is ROHS3 Compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes. Confirm compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the difference in insulation diameter specifications?

A: The 3M 94737 and 94736 specify 0.170" (4.32mm) insulation diameter. The Panduit PN14-6RN-C provides a range of 0.080" to 0.162" (2.03mm to 4.11mm). Verify wire insulation dimensions match the terminal specifications for your application.

Q: Can I use these parts interchangeably in existing assemblies?

A: All three parts maintain the same wire gauge range (14-16 AWG), stud size (#6), and crimp termination. Dimensional and insulation material variations require verification against your specific assembly and environmental requirements before substitution.
