PMNF1-4R-C Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The PMNF1-4R-C is a ring terminal connector manufactured by Panduit Corp, classified as a circular terminal designed for M4 stud applications. This component is rated for 18-22 AWG wire gauges and features crimp termination with serrated contact surfaces. The part is currently listed as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure procurement availability for new applications and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PMNF1-4R-C is determined by the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Wire gauge range: 18-22 AWG
• Termination method: Crimp
• Terminal type: Circular
• Contact material: Copper
• Contact finish: Tin
• Insulation material: Polyamide (PA), Nylon
• Mounting type: Free Hanging (In-Line)
• Series: Pan-Term®

Stud/Tab Size Consideration: The primary distinction between the main part and its substitute relates to the stud connection point. The PMNF1-4R-C accommodates M4 studs, while the substitute PNF18-8R-C is designed for #8 studs. This represents a mechanical interface change that must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The PNF18-8R-C serves as an active substitute for the obsolete PMNF1-4R-C within the Pan-Term® series. Both components share identical electrical and material specifications for wire gauge, termination method, contact composition, and insulation properties.

The substitute part carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to these requirements. The main part's compliance status was not specified in available documentation.

The critical distinction between these components is the stud interface: M4 versus #8. This mechanical difference requires verification against the specific application's fastening requirements. Both parts maintain identical outer width dimensions (0.310") and comparable overall lengths (0.850" versus 0.870"), supporting similar spatial constraints in most applications.

The PNF18-8R-C is currently in active production with 1403 units in stock, ensuring procurement availability and supply chain continuity compared to the obsolete status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the PNF18-8R-C directly replace the PMNF1-4R-C in all applications?

A: Direct replacement depends on the stud size requirement. The PMNF1-4R-C is designed for M4 studs, while the PNF18-8R-C accommodates #8 studs. If the application uses M4 studs, the substitute requires mechanical interface modification. If the application uses #8 studs, the substitute is compatible.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both components share identical wire gauge ratings (18-22 AWG), termination method (crimp), contact material (copper), contact finish (tin), and insulation material (polyamide nylon). Electrical performance characteristics are equivalent.

Q: What is the significance of the ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates the PNF18-8R-C meets Restriction of Hazardous Substances Directive requirements. This certification is relevant for applications subject to environmental and regulatory compliance mandates. The original part's compliance status was not documented.

Q: Are there dimensional differences that affect installation?

A: The outer width remains identical at 0.310" (7.87mm). The overall length differs slightly: PMNF1-4R-C measures 0.850" (21.59mm) while PNF18-8R-C measures 0.870" (22.10mm). This 0.020" difference is negligible for most applications but should be verified against specific spatial constraints.

Q: What is the insulation diameter specification for the substitute?

A: The PNF18-8R-C specifies an insulation diameter range of 0.080" to 0.136" (2.03mm to 3.45mm), accommodating the 18-22 AWG wire gauge range. The original part specified 0.148" (3.76mm) insulation diameter.

Q: Is the substitute part available in different packaging options?

A: The PNF18-8R-C is available in bulk packaging. The original part's packaging specification was not provided in available documentation.
