MN4-516RK Equivalent & Substitute Parts

Part Overview

The MN4-516RK is an insulated ring terminal connector manufactured by 3M, designed for 4 AWG wire termination on a 5/16 stud. This circular terminal features a brazed seam construction with tin-plated copper contact material and yellow polyamide insulation. The part is actively produced and RoHS compliant, making it suitable for applications requiring reliable electrical connections in industrial and commercial environments. Substitute parts may be required due to inventory availability, lead time considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MN4-516RK is determined by strict adherence to the following critical parameters:

• Wire gauge must be 4 AWG
• Stud size must be 5/16
• Termination method must be crimp
• Insulation diameter must be 0.515" (13.08mm)
• Contact material must be copper-based with tin finish
• Mounting type must be free hanging (in-line)
• Insulation must be present

The PV4-56RX-T qualifies as a substitute based on these parameters. While the terminal type differs (flat sided versus circular), both configurations accommodate the same wire gauge, stud size, and electrical interface requirements. Dimensional variations in thickness and overall length do not affect functional compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the MN4-516RK and PV4-56RX-T meet the core electrical and mechanical requirements for 4 AWG wire termination on 5/16 studs. The MN4-516RK features polyamide insulation with a circular terminal geometry and greater thickness. The PV4-56RX-T provides a flat-sided terminal configuration with vinyl insulation and reduced thickness.

Selection between these parts should be based on:

• Availability and lead time requirements
• Specific application space constraints (the PV4-56RX-T has a longer overall length)
• Insulation material compatibility with the operating environment (polyamide versus vinyl)
• Terminal geometry preference for the mechanical assembly

Both parts are actively produced and maintain current compliance certifications (RoHS and REACH). The MN4-516RK carries MSL Level 1 (unlimited moisture sensitivity), while the PV4-56RX-T is not applicable for MSL classification.

Frequently Asked Questions (FAQ)

Q: Can the PV4-56RX-T replace the MN4-516RK in all applications?

A: The PV4-56RX-T qualifies as a substitute based on wire gauge, stud size, termination method, and insulation diameter. However, differences in terminal geometry (flat sided versus circular), insulation material (vinyl versus polyamide), and overall dimensions may affect fit in space-constrained assemblies. Verify mechanical clearance and insulation material compatibility with your specific application environment.

Q: What is the significance of the terminal type difference (circular versus flat sided)?

A: Both terminal types accommodate the same 4 AWG wire and 5/16 stud interface. The circular design of the MN4-516RK and flat-sided design of the PV4-56RX-T represent different mechanical profiles. The choice depends on assembly requirements and available mounting space.

Q: Are there differences in electrical performance between these substitutes?

A: Both parts feature tin-plated copper contacts and crimp termination, providing equivalent electrical performance for the specified wire gauge and stud size. Contact resistance and current-carrying capacity are determined by these common parameters.

Q: What is the impact of insulation material differences?

A: The MN4-516RK uses polyamide (nylon) insulation, while the PV4-56RX-T uses vinyl. Material selection affects temperature range, chemical resistance, and flexibility. Verify that the substitute's insulation material is compatible with your operating environment and temperature requirements.

Q: Do both parts meet current compliance standards?

A: Yes. The MN4-516RK is RoHS Compliant and REACH Unaffected. The PV4-56RX-T is ROHS3 Compliant and REACH Unaffected. Both parts meet current regulatory requirements for electronic component manufacturing.
