P4-38RHT6-E Equivalent & Substitute Parts

Part Overview

The P4-38RHT6-E is a ring terminal connector manufactured by Panduit Corp, classified as a D-shaped terminal designed for 4 AWG wire with a 3/8 inch stud connection. This component is rated as obsolete, indicating discontinuation from active production. The terminal features a brazed seam construction with copper contact material and nickel finish, suitable for non-insulated crimp applications in free-hanging inline mounting configurations.

Due to the obsolete status of the P4-38RHT6-E, identification of equivalent substitute components is necessary to maintain design continuity and ensure procurement availability for new builds and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4-38RHT6-E is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Wire Gauge: 4 AWG
• Stud/Tab Size: 3/8 Stud
• Termination Type: Crimp
• Mounting Type: Free Hanging (In-Line)
• Insulation: Non-Insulated
• Thickness: 0.050" (1.27mm)
• Contact Material: Copper
• Features: Brazed Seam

The primary distinction between the main part and its substitute lies in the terminal geometry. The P4-38RHT6-E features a D-shaped terminal profile, while the substitute part P4-38R-E utilizes a circular terminal profile. Both configurations maintain identical electrical and mechanical specifications for wire gauge, stud size, crimp termination, and mounting characteristics. The geometric difference does not affect functional compatibility when stud hole diameter and spacing requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The P4-38R-E serves as the direct substitute for the obsolete P4-38RHT6-E based on the following engineering criteria:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for applications subject to these standards. Both are classified under identical HTSUS and ECCN codes, confirming their functional classification parity.

Electrical and Mechanical Compatibility: The substitute part maintains all critical electrical and mechanical parameters: 4 AWG wire gauge capacity, 3/8 inch stud connection, 0.050 inch thickness, copper contact material, and brazed seam construction. These specifications ensure direct functional replacement in circuits and assemblies designed for the original component.

Product Status Advantage: The P4-38R-E holds active product status with documented inventory availability (883 pieces), whereas the P4-38RHT6-E is obsolete. Selection of the active substitute ensures long-term procurement reliability and supply chain continuity.

Contact Finish Variation: The substitute incorporates tin contact finish compared to the nickel finish of the original part. Both finishes are compatible with standard copper wire termination and provide equivalent corrosion resistance in non-insulated applications.

Geometric Consideration: The circular terminal profile of the P4-38R-E replaces the D-shaped profile of the P4-38RHT6-E. This geometric change does not affect electrical performance or mechanical mounting when stud hole diameter accommodates the 0.680 inch outer edge width common to both parts.

Frequently Asked Questions (FAQ)

Q: Can the P4-38R-E directly replace the P4-38RHT6-E in existing designs?

A: Yes. The P4-38R-E maintains all critical electrical and mechanical specifications: 4 AWG wire gauge, 3/8 inch stud size, crimp termination, and 0.050 inch thickness. The primary difference is terminal geometry (circular versus D-shaped). Substitution is valid when the mounting hole accommodates the 0.680 inch outer edge width.

Q: What is the significance of the terminal shape difference?

A: The D-shaped profile of the P4-38RHT6-E and the circular profile of the P4-38R-E represent geometric variations that do not affect electrical performance or crimp connection integrity. Both shapes accommodate the same stud size and wire gauge. Selection between profiles depends on mechanical fit within the specific assembly or mounting configuration.

Q: Does the contact finish change from nickel to tin affect performance?

A: Both nickel and tin finishes provide equivalent corrosion resistance and electrical conductivity for non-insulated copper wire terminations. The tin finish of the P4-38R-E is fully compatible with standard 4 AWG wire applications and does not compromise electrical or mechanical performance.

Q: Why is the P4-38RHT6-E listed as obsolete?

A: Obsolete status indicates the component has been discontinued from active production by Panduit Corp. The P4-38R-E represents the active equivalent within the Pan-Term® series, ensuring continued availability and supply chain support.

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

A: The P4-38RHT6-E packaging specification is not provided in available documentation. The P4-38R-E is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the P4-38RHT6-E and P4-38R-E are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.90.4000) codes, confirming regulatory equivalence.

Q: What is the length difference between the two parts?

A: The P4-38RHT6-E has an overall length of 1.400 inches (35.56mm), while the P4-38R-E measures 1.460 inches (37.08mm). This 0.060 inch difference results from the geometric profile variation and does not affect functional compatibility in standard mounting applications.
