PV8-56RX-Q Equivalent & Substitute Parts

Part Overview

The PV8-56RX-Q is an insulated ring terminal connector manufactured by Panduit Corp, designed for 8 AWG wire termination on a 5/16 stud. This flat-sided ring terminal features a brazed seam construction with tin-plated copper contact material and red vinyl insulation. The product is classified as obsolete, necessitating identification of active equivalent components that maintain functional compatibility for applications requiring 8 AWG crimp ring terminals with 5/16 stud mounting.

Key Parameters

Parameter	Value
Wire Gauge	8 AWG
Stud/Tab Size	5/16 Stud
Termination Type	Crimp

Thickness	0.040" (1.02mm)
Mounting Type	Free Hanging (In-Line)

Substitute Part Grouping Explanation

Substitution of the PV8-56RX-Q is determined by strict equivalence across the following critical parameters:

Wire Gauge: 8 AWG (electrical current capacity requirement)
Stud/Tab Size: 5/16 Stud (mechanical mounting compatibility)
Termination Method: Crimp (assembly process compatibility)
Contact Material and Finish: Copper with Tin plating (electrical conductivity and corrosion resistance)
Insulation Specifications: Insulated construction with 0.360" insulation diameter (electrical safety and dimensional fit)
Thickness: 0.040" (1.02mm) (mechanical fit within assembly constraints)
Mounting Configuration: Free Hanging (In-Line) (installation method compatibility)

The substitute part TE Connectivity AMP Connectors 52291-4 satisfies all critical substitution parameters. The primary difference is terminal geometry (circular versus flat-sided) and insulation material composition (PVC versus vinyl), neither of which affects functional compatibility for the specified electrical and mechanical requirements.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 52291-4 is the direct functional substitute for the obsolete PV8-56RX-Q. Selection of this substitute is supported by the following engineering factors:

Electrical Equivalence: Both components are rated for 8 AWG wire termination with identical copper-tin contact specifications, ensuring equivalent electrical performance and current-carrying capacity.

Mechanical Compatibility: Identical stud size (5/16), thickness (0.040"), and insulation diameter (0.360") confirm mechanical fit within existing assemblies and mounting structures.

Compliance Status: The 52291-4 is ROHS3 compliant and carries active product status, providing long-term supply availability and regulatory alignment for new designs and production runs.

Termination Process: Both components utilize crimp termination methodology, allowing use of existing crimping tools and assembly procedures without process modification.

Geometric Variation: The circular terminal geometry of the 52291-4 versus the flat-sided design of the PV8-56RX-Q does not impact functional performance for applications where stud mounting is the primary mechanical interface.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 52291-4 be used as a direct replacement for the Panduit PV8-56RX-Q in existing assemblies?

A: Yes. The 52291-4 meets all critical electrical and mechanical parameters: 8 AWG wire gauge, 5/16 stud size, 0.040" thickness, 0.360" insulation diameter, and crimp termination. The circular terminal geometry does not affect stud mounting compatibility.

Q: What is the difference between the flat-sided and circular terminal designs?

A: The flat-sided design of the PV8-56RX-Q and the circular design of the 52291-4 represent different terminal geometries. Both designs accommodate the same 5/16 stud and deliver equivalent electrical performance. Terminal geometry selection is typically driven by assembly tooling and aesthetic preferences rather than electrical function.

Q: Are the insulation materials interchangeable?

A: The PV8-56RX-Q uses vinyl insulation while the 52291-4 uses PVC (Poly-Vinyl Chloride). Both materials provide equivalent electrical insulation properties and environmental protection for 8 AWG applications. PVC is a subset classification of vinyl polymers and delivers the same functional performance.

Q: Does the ROHS3 compliance of the 52291-4 affect compatibility with existing designs?

A: No. ROHS3 compliance indicates the 52291-4 meets current regulatory requirements for hazardous substance restrictions. This compliance status does not alter electrical or mechanical performance and makes the 52291-4 suitable for both legacy and new design implementations.

Q: What is the packaging format for the substitute part?

A: The 52291-4 is supplied in Cut Tape (CT) packaging format, which is standard for high-volume component distribution and automated assembly processes.

Q: Are crimping tools compatible between the two part numbers?

A: Yes. Both the PV8-56RX-Q and 52291-4 utilize crimp termination methodology for 8 AWG wire. Existing crimping tools and dies specified for 8 AWG ring terminals are compatible with both components.
