PV4-12RX-E Equivalent & Substitute Parts
Part Overview
The PV4-12RX-E is an insulated ring terminal connector manufactured by Panduit Corp, designed for 4 AWG wire gauge applications with a 1/2 inch stud connection. 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 that maintain electrical and mechanical compatibility for ongoing applications and new designs.

Substitute Part Grouping Explanation
Substitute parts for the PV4-12RX-E are identified based on strict electrical and mechanical compatibility criteria. All substitute parts maintain the following core parameters identical to the main part:
- Wire gauge: 4 AWG
- Terminal type: Flat sided
- Termination method: Crimp
- Insulation material: Vinyl
- Contact material: Copper with tin finish
- Mounting type: Free hanging (in-line)
- Series designation: Pan-Term®
- Thickness: 0.050" (1.27mm)
- RoHS3 compliance status
- REACH unaffected status
The primary variable parameter distinguishing substitute parts is the stud/tab size. Substitute parts are available with 5/16 inch and 3/8 inch stud sizes, accommodating different mounting hole specifications while preserving all other electrical and mechanical characteristics. Selection of the appropriate substitute depends exclusively on the stud size requirement of the target application.

Engineering Selection Recommendations
The PV4-12RX-E is classified as obsolete and should be replaced with an active equivalent for new designs and ongoing procurement. Both substitute parts, PV4-56R-E and PV4-38RX-E, are active products with current manufacturing status and full availability.
Selection between substitute parts is determined by the stud hole size specification in the target application:
- PV4-56R-E is selected for applications requiring a 5/16 inch stud connection
- PV4-38RX-E is selected for applications requiring a 3/8 inch stud connection
Both substitute parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part. The electrical performance characteristics remain identical across all three parts due to matching wire gauge, contact material, contact finish, and termination method specifications.
Frequently Asked Questions (FAQ)
Q: Can PV4-56R-E or PV4-38RX-E be used interchangeably with PV4-12RX-E?
A: Interchangeability depends on the stud hole size in the target application. The substitute parts differ only in stud size (5/16 inch or 3/8 inch versus the original 1/2 inch). All other electrical and mechanical characteristics are identical. The correct substitute must match the mounting hole specification of the application.
Q: What is the primary reason for substituting the PV4-12RX-E?
A: The PV4-12RX-E is classified as obsolete. Both substitute parts, PV4-56R-E and PV4-38RX-E, are active products with current manufacturing and full availability, ensuring long-term supply chain reliability.
Q: Are the substitute parts compliant with the same regulatory standards?
A: Yes. Both PV4-56R-E and PV4-38RX-E maintain ROHS3 compliance and REACH unaffected status, identical to the original PV4-12RX-E.
Q: How do the physical dimensions differ between the main part and substitutes?
A: The width and length dimensions vary slightly due to the different stud sizes. The PV4-56R-E (5/16 inch stud) has a width of 0.680 inches and length of 1.950 inches. The PV4-38RX-E (3/8 inch stud) has a width of 0.680 inches and length of 1.940 inches. The original PV4-12RX-E (1/2 inch stud) has a width of 0.860 inches and length of 2.030 inches. Thickness remains constant at 0.050 inches across all parts.
Q: What wire gauge do the substitute parts support?
A: Both substitute parts support 4 AWG wire gauge, identical to the original PV4-12RX-E.
Q: Are the substitute parts available in the same packaging format?
A: The original PV4-12RX-E was supplied in bulk packaging. Both substitute parts, PV4-56R-E and PV4-38RX-E, are also available in bulk packaging.
