MN4-10RK Equivalent & Substitute Parts

Part Overview

The MN4-10RK is an insulated ring terminal connector manufactured by 3M, designed for 4 AWG wire gauge applications with a #10 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 is currently active in production with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the core functional requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MN4-10RK is determined by strict alignment of critical electrical and mechanical parameters. The primary substitution criteria include wire gauge (4 AWG), stud size (#10), termination method (crimp), insulation type (insulated), contact material composition (copper with tin plating), and insulation diameter (0.515"). The PV4-10RX-T from Panduit Corp meets these core functional requirements, with the primary design difference being terminal geometry: the MN4-10RK features a circular terminal type, while the PV4-10RX-T employs a flat-sided terminal configuration. Both maintain equivalent electrical performance and mechanical compatibility at the connection interface.

Parameter Comparison

Engineering Selection Recommendations

Both the MN4-10RK and PV4-10RX-T maintain active production status with current RoHS compliance certifications. The MN4-10RK carries RoHS Compliant status, while the PV4-10RX-T is ROHS3 Compliant. Selection between these parts should be based on specific application requirements regarding terminal geometry and insulation material compatibility. The circular design of the MN4-10RK and the flat-sided configuration of the PV4-10RX-T may present different mechanical fit characteristics in constrained mounting environments. The insulation material difference—nylon for the MN4-10RK versus vinyl for the PV4-10RX-T—may influence performance in temperature-sensitive or chemical exposure applications. Both parts satisfy the core electrical and mechanical requirements for 4 AWG crimp ring terminal connections at #10 stud interfaces.

Frequently Asked Questions (FAQ)

Q: Can the PV4-10RX-T directly replace the MN4-10RK in all applications?

A: The PV4-10RX-T meets the critical electrical and mechanical parameters (wire gauge, stud size, termination method, contact material, and insulation diameter). However, the difference in terminal geometry (circular versus flat-sided) and insulation material (nylon versus vinyl) may affect fit in space-constrained assemblies or applications with specific temperature or chemical exposure requirements. Verification of mechanical fit and environmental compatibility is necessary for specific installations.

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

A: The primary differences are terminal geometry (MN4-10RK is circular; PV4-10RX-T is flat-sided), thickness (0.075" versus 0.050"), width (0.680" versus 0.550"), overall length (1.740" versus 1.870"), and insulation material (nylon versus vinyl). Electrical performance and stud interface compatibility remain equivalent.

Q: Are both parts RoHS compliant?

A: Yes. The MN4-10RK is RoHS Compliant, and the PV4-10RX-T is ROHS3 Compliant. Both meet current regulatory requirements.

Q: What wire gauge and stud size do these terminals support?

A: Both terminals are rated for 4 AWG wire gauge with #10 stud connections, suitable for crimp termination applications.

Q: Does insulation material affect electrical performance?

A: Insulation material does not affect the electrical conductivity or contact resistance at the stud interface. Material selection impacts thermal stability, chemical resistance, and mechanical flexibility characteristics specific to the application environment.
