PV4-12R-E Equivalent & Substitute Parts

Part Overview

The PV4-12R-E is an insulated ring terminal connector manufactured by Panduit Corp, designed for 4 AWG wire termination on a 1/2 inch stud. This flat-sided ring terminal features a brazed seam construction with tin-plated copper contact material and yellow vinyl insulation. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PV4-12R-E is determined by the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Wire Gauge: 4 AWG
• Terminal Type: Flat Sided
• Termination Method: Crimp
• Contact Material: Copper
• Contact Finish: Tin
• Insulation Material: Vinyl
• Series: Pan-Term®
• Base Product Number: PV4

Variable Parameters (Allowable Differences):

• Stud/Tab Size: The primary differentiator among PV4 series terminals
• Overall dimensions (Length, Width, Thickness, Insulation Diameter): Scale proportionally with stud size
• Product Status: Active alternatives preferred over obsolete originals
• Packaging configuration

The PV4-56R-E is classified as a substitute because it maintains all fixed parameters while accommodating a different stud size (5/16 inch versus 1/2 inch). This substitution is valid when the application circuit board or equipment mounting point accepts the 5/16 inch stud configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Stud Size Compatibility

The PV4-56R-E substitute is applicable only when the target equipment or circuit board mounting point is designed for a 5/16 inch stud. The 1/2 inch stud of the original PV4-12R-E cannot be directly replaced with the 5/16 inch stud without mechanical modification to the receiving component.

Compliance and Regulatory Status

Both the PV4-12R-E and PV4-56R-E maintain identical compliance certifications:

• ROHS3 Compliant
• REACH Unaffected
• ECCN: EAR99
• HTSUS: 8536.90.4000

Product Status Impact

The PV4-12R-E is classified as obsolete. The PV4-56R-E is active and maintains current manufacturing support. For new designs or long-term procurement strategies, the active PV4-56R-E is the preferred alternative when stud size compatibility exists.

Electrical and Mechanical Equivalence

Both terminals are constructed with identical contact material (copper), contact finish (tin), insulation material (vinyl), and termination method (crimp). The electrical performance characteristics for 4 AWG wire termination are equivalent between the two parts. Dimensional differences are proportional to the stud size reduction and do not affect electrical function.

Frequently Asked Questions (FAQ)

Q: Can the PV4-56R-E directly replace the PV4-12R-E in all applications?

A: No. Direct replacement is only possible if the receiving equipment or circuit board is designed to accept a 5/16 inch stud. The PV4-12R-E uses a 1/2 inch stud. Physical modification to the mounting point would be required for substitution in applications designed for 1/2 inch studs.

Q: What is the primary difference between these two parts?

A: The stud size differs: PV4-12R-E has a 1/2 inch stud, while PV4-56R-E has a 5/16 inch stud. All other electrical and material specifications remain identical.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the PV4-12R-E and PV4-56R-E are ROHS3 compliant and REACH unaffected. Both carry the same ECCN and HTSUS classifications.

Q: Why is the PV4-12R-E listed as obsolete?

A: Product status reflects manufacturing availability. The PV4-56R-E is currently active and available for procurement. For applications requiring a 1/2 inch stud, alternative active ring terminals from the PV4 series or other manufacturers may be necessary.

Q: Are the crimp specifications identical between these parts?

A: Yes. Both terminals are designed for 4 AWG wire crimp termination using identical contact material (copper) and contact finish (tin). Crimp tool specifications and procedures remain consistent.

Q: What is the significance of the brazed seam feature?

A: The brazed seam construction provides structural integrity and electrical continuity at the terminal joint. This feature is present on both the PV4-12R-E and PV4-56R-E.

Q: Can these terminals be used interchangeably in the same batch or assembly?

A: No. The different stud sizes prevent interchangeable use within the same assembly unless the mounting points are specifically designed to accommodate both sizes.
