3M 16-14-W Ring Terminal Connector - Equivalent & Substitute Parts

Part Overview

The 3M 16-14-W is an active, ROHS3 compliant ring terminal connector designed for 4 AWG wire gauge applications with a 1/4 inch stud connection. This non-insulated, copper ETP contact terminal features a brazed seam construction and tin finish, suitable for free-hanging in-line mounting configurations. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for this terminal connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 16-14-W is determined by the following critical parameters:

• Wire Gauge: 4 AWG (fixed requirement)
• Terminal Type: Circular ring configuration (fixed requirement)
• Stud/Tab Size: 1/4 inch stud (fixed requirement)
• Termination Method: Crimp connection (fixed requirement)
• Contact Material: Copper composition (fixed requirement)
• Contact Finish: Tin plating (fixed requirement)
• Insulation Type: Non-insulated (fixed requirement)
• Mounting Configuration: Free hanging in-line (fixed requirement)
• RoHS Compliance: ROHS3 compliant (regulatory requirement)

The Panduit Corp P4-14R-E meets all critical substitution criteria. Dimensional variations in thickness, width, and length fall within acceptable mechanical tolerances for this terminal connector category and do not affect functional compatibility in standard 4 AWG 1/4 stud ring terminal applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 16-14-W and Panduit P4-14R-E are active products with ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on:

• Inventory Availability: 3M 16-14-W has 1,306 pieces in stock; Panduit P4-14R-E has 945 pieces in stock
• Regulatory Compliance: Both parts meet ROHS3 requirements and are suitable for applications requiring environmental compliance
• Mechanical Fit: Dimensional differences exist but do not affect electrical performance or functional compatibility in standard 4 AWG 1/4 stud ring terminal applications
• Supply Chain Continuity: Either part may be selected based on procurement lead times and supplier availability

Frequently Asked Questions (FAQ)

Q: Can the Panduit P4-14R-E replace the 3M 16-14-W in my application?

A: Yes. Both parts are circular ring terminals for 4 AWG wire with 1/4 inch stud connections, non-insulated copper tin-plated construction, and crimp termination. Dimensional variations do not affect electrical or mechanical compatibility in standard applications.

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

A: The primary differences are dimensional: the Panduit P4-14R-E is thinner (0.050" vs. 0.075"), narrower (0.550" vs. 0.680"), and slightly longer (1.400" vs. 1.340"). These variations fall within acceptable mechanical tolerances for this terminal category.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3M 16-14-W and Panduit P4-14R-E are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: What wire gauge do these terminals support?

A: Both terminals are designed for 4 AWG wire gauge applications exclusively.

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

A: Both terminals feature a 1/4 inch stud connection point.

Q: Are these terminals insulated?

A: No. Both the 3M 16-14-W and Panduit P4-14R-E are non-insulated terminals with exposed copper contacts.

Q: What termination method is used?

A: Both terminals use crimp termination for wire connection.

Q: What contact material and finish are used?

A: Both terminals feature copper contacts with tin plating for corrosion resistance and electrical conductivity.
