3M 14-38-W Ring Terminal Connector - Equivalent & Substitute Parts

Part Overview

The 3M 14-38-W is a non-insulated ring terminal connector designed for 8 AWG wire applications with a 3/8 inch stud connection. This circular terminal features a brazed seam construction and tin-plated copper contact material, suitable for free-hanging in-line mounting configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current procurement and deployment in electrical assembly applications where ring terminal connectors are specified.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across wire gauge, stud size, termination method, and contact material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 14-38-W is determined by strict equivalence across the following critical parameters:

• Wire Gauge: 8 AWG (fixed requirement)
• Stud Size: 3/8 inch (fixed requirement)
• Terminal Type: Circular ring configuration (fixed requirement)
• Termination Method: Crimp connection (fixed requirement)
• Contact Material: Copper with tin finish (fixed requirement)
• Insulation Type: Non-insulated (fixed requirement)
• Mounting Configuration: Free hanging in-line (fixed requirement)

The Panduit Corp P8-38R-Q meets all critical substitution criteria. Dimensional variations in thickness (0.040" vs. 0.050") and overall length (1.250" vs. 1.060") remain within acceptable tolerance ranges for equivalent functional performance in standard 8 AWG ring terminal applications. Both parts maintain identical wire gauge, stud size, contact material, and termination specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 14-38-W and Panduit P8-38R-Q maintain Active product status and ROHS3 compliance, confirming current manufacturing availability and regulatory alignment for new designs and production applications.

The Panduit P8-38R-Q is designated as the manufacturer-recommended substitute. Selection between these parts should be based on:

• Inventory availability: 3M 14-38-W (738 pcs) vs. Panduit P8-38R-Q (943 pcs)
• Dimensional fit: The Panduit part exhibits reduced thickness (0.040" vs. 0.050") and increased overall length (1.250" vs. 1.060"), which may affect fit in space-constrained applications or specific mounting configurations
• Supply chain continuity: Either part provides equivalent electrical performance for 8 AWG crimp ring terminal applications with 3/8 inch stud connections

Both parts are suitable for direct substitution in standard electrical assembly applications where the dimensional variations do not conflict with mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the Panduit P8-38R-Q replace the 3M 14-38-W in all applications?

A: The Panduit P8-38R-Q meets all critical electrical and mechanical substitution criteria for 8 AWG ring terminal applications with 3/8 inch studs. However, dimensional differences (thickness and length) must be verified against specific mounting or space constraints in your application before implementation.

Q: What are the key differences between these two parts?

A: Both parts are functionally equivalent for 8 AWG crimp ring terminal connections. The primary differences are manufacturer (3M vs. Panduit), thickness (0.050" vs. 0.040"), overall length (1.060" vs. 1.250"), and series designation (Pan-Term® for Panduit). Electrical performance and contact material specifications are equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both the 3M 14-38-W and Panduit P8-38R-Q are ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: What wire gauge do these terminals support?

A: Both terminals are designed for 8 AWG wire applications exclusively. Wire gauge is a fixed substitution criterion and cannot vary between equivalent parts.

Q: What is the stud size for these ring terminals?

A: Both terminals feature a 3/8 inch stud connection. Stud size is a critical fixed parameter for substitution eligibility.

Q: Can these non-insulated terminals be used interchangeably with insulated ring terminals?

A: No. These are non-insulated terminals and cannot be substituted with insulated variants. Insulation type is a fixed substitution criterion determined by application requirements.
