PMNF2-4R-X Ring Terminal Connector M4 Equivalent & Substitute Parts

Part Overview

The PMNF2-4R-X is a circular ring terminal connector manufactured by Panduit Corp, designed for 14-16 AWG wire gauges with M4 stud termination. This insulated crimp terminal features a serrated termination design and tin-plated electrolytic copper contacts. The product is classified as obsolete, necessitating identification of active equivalent components for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PMNF2-4R-X is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal Type: Circular
• Stud/Tab Size: M4 Stud
• Wire Gauge: 14-16 AWG
• Termination Method: Crimp
• Insulation: Insulated
• Contact Finish: Tin
• Mounting Type: Free Hanging (In-Line)
• Features: Serrated Termination

The substitute part 342143-1 (TE Connectivity AMP Connectors, Plasti-Grip series) satisfies all mandatory matching parameters. This part is classified as active product status with current inventory availability, making it suitable for replacement applications where the obsolete PMNF2-4R-X is no longer procurable.

Parameter Comparison

Engineering Selection Recommendations

The 342143-1 (TE Connectivity) serves as the direct substitute for the obsolete PMNF2-4R-X. Selection of this substitute is based on the following engineering factors:

Product Status: The PMNF2-4R-X is classified as obsolete, while 342143-1 maintains active product status with established supply chain availability (32,900 pieces in stock).

Compliance & Certifications: The 342143-1 is ROHS3 compliant and REACH unaffected, providing regulatory compliance for current manufacturing standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Functional Equivalence: All critical electrical and mechanical parameters align between the two components, including terminal geometry, wire gauge compatibility, crimp termination method, and contact finish specifications.

Insulation Material Variance: The substitute employs Poly-Vinyl Chloride (PVC) insulation versus the original Polyamide (PA66) nylon insulation. Both materials are standard for insulated ring terminal applications and provide equivalent electrical isolation properties for the specified wire gauge and voltage class.

Frequently Asked Questions (FAQ)

Q: Can 342143-1 directly replace PMNF2-4R-X in existing assemblies?

A: Yes. The 342143-1 matches all critical parameters: M4 stud size, 14-16 AWG wire gauge, crimp termination, serrated termination feature, tin contact finish, and free-hanging mounting configuration. Physical dimensions are within acceptable tolerance ranges for standard M4 stud applications.

Q: What is the difference in insulation material between these parts?

A: The PMNF2-4R-X uses Polyamide (PA66) nylon insulation, while 342143-1 uses Poly-Vinyl Chloride (PVC) insulation. Both materials provide adequate electrical isolation for 14-16 AWG conductors and are standard in ring terminal connector applications.

Q: Are there packaging differences between the main part and substitute?

A: The PMNF2-4R-X is listed with unspecified packaging, while 342143-1 is supplied in bulk packaging. Bulk packaging is standard for active production components and does not affect functional compatibility.

Q: What compliance certifications apply to the substitute part?

A: The 342143-1 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in EU and international markets.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are similar with minor variations. The 342143-1 has a width of 0.343" (8.71mm) versus 0.310" (7.87mm) for the original, and length of 0.874" (22.20mm) versus 0.860" (21.84mm). These variations are within standard tolerance ranges for M4 stud applications and do not affect functional compatibility.

Q: What is the moisture sensitivity level for the substitute part?

A: The 342143-1 has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
