MN4-14RK Equivalent & Substitute Parts

Part Overview

The MN4-14RK is an insulated ring terminal connector manufactured by 3M, designed for 4 AWG wire termination on 1/4 inch studs. This circular terminal features a crimp connection method and is part of the Scotchlok™ series. The product is currently active and widely used in electrical assembly applications requiring reliable ring terminal connections. Substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements where alternative terminal geometries are acceptable.

Key Parameters

Substitute Part Grouping Explanation

The PV4-14RX-T from Panduit Corp qualifies as a substitute for the MN4-14RK based on the following critical parameters:

• Wire Gauge: Both parts accommodate 4 AWG wire
• Stud/Tab Size: Both parts are designed for 1/4 inch studs
• Termination Method: Both use crimp termination
• Insulation Status: Both are insulated terminals
• Contact Material: Both use copper with tin finish
• Insulation Diameter: Both maintain 0.515" (13.08mm) insulation diameter
• Color: Both are yellow
• Compliance: Both are RoHS compliant and REACH unaffected

The primary difference is terminal geometry: MN4-14RK features a circular terminal design, while PV4-14RX-T features a flat-sided design. This geometric variation does not affect electrical compatibility when both terminals are crimped to 4 AWG wire and mounted on 1/4 inch studs.

Parameter Comparison

Engineering Selection Recommendations

Both MN4-14RK and PV4-14RX-T meet the core electrical and mechanical requirements for 4 AWG ring terminal applications on 1/4 inch studs. Selection between these parts should be based on:

• Mechanical space constraints: The PV4-14RX-T flat-sided design has reduced width (0.550" vs 0.680") and thickness (0.050" vs 0.075"), making it suitable for applications with tighter dimensional tolerances.
• Inventory availability: MN4-14RK has 739 units in stock; PV4-14RX-T has 1184 units in stock.
• Compliance requirements: Both parts are RoHS compliant and REACH unaffected, suitable for regulated applications.
• Series preference: MN4-14RK belongs to the Scotchlok™ series; PV4-14RX-T belongs to the Pan-Term® series. Either series is acceptable based on electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can PV4-14RX-T replace MN4-14RK in existing assemblies?

A: Yes, provided the mechanical envelope permits the dimensional differences. Both terminals crimp to 4 AWG wire and mount on 1/4 inch studs with identical insulation diameter and electrical properties.

Q: What is the significance of the terminal geometry difference (circular vs. flat-sided)?

A: Terminal geometry does not affect electrical performance when both are properly crimped to the same wire gauge and mounted on the same stud size. Geometry selection is driven by mechanical fit and assembly space requirements.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant and REACH unaffected. MN4-14RK is RoHS Compliant; PV4-14RX-T is ROHS3 Compliant. Both meet current regulatory requirements.

Q: What packaging is available for these parts?

A: Both MN4-14RK and PV4-14RX-T are supplied in bulk packaging.

Q: Do these terminals require different crimping tools?

A: Crimping tool compatibility depends on the specific tool design and its acceptance of both circular and flat-sided terminal geometries. Verify tool specifications with the tool manufacturer.
