Equivalent & Substitute Parts: P73-D

Part Overview

The P73-D is a twist-on wire cap connector manufactured by Panduit Corp, designed for terminating 16-20 AWG wire gauges. This component is classified as a fully insulated terminal with a single wire entry point and is part of the P-Conn Python™ series. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and system support applications where this connector type is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P73-D is determined by the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Terminal Type: Twist On Wire Cap (functional equivalence)
• Termination Method: Twist On (mechanical compatibility)
• Insulation: Fully Insulated (safety and electrical isolation)
• Wire Gauge Range: Must accommodate the 16-20 AWG specification
• Color: Orange (visual identification and industry standard coding)

The substitute part 0191600041 (Molex 19160 series) satisfies these criteria through a wire gauge range of 14-22 AWG, which encompasses the required 16-20 AWG specification. Both parts employ identical twist-on termination methodology and maintain full insulation properties. The orange color designation remains consistent across both components.

Engineering Selection Recommendations

The Molex 0191600041 connector serves as a direct functional substitute for the obsolete Panduit P73-D. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The P73-D is obsolete, while the Molex 0191600041 maintains active product status with confirmed inventory availability (21,503 pieces in stock), ensuring long-term supply chain continuity.

Compliance and Certification: The substitute part carries ROHS3 compliance certification and maintains REACH unaffected status, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8546.90.0000) classifications, confirming equivalent trade and export compliance.

Functional Equivalence: Both connectors employ identical twist-on termination methodology and maintain full insulation properties. The wire gauge range of the substitute (14-22 AWG) fully encompasses the required 16-20 AWG specification of the original part.

Physical and Electrical Characteristics: Orange color designation, single wire entry configuration for the specified gauge range, and fully insulated construction remain consistent between the original and substitute components.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0191600041 directly replace the Panduit P73-D in existing applications?

A: Yes. Both components are twist-on wire cap connectors with fully insulated construction, identical termination methodology, and compatible wire gauge specifications. The Molex part accommodates the 16-20 AWG range required by the original specification.

Q: What is the significance of the wire gauge range difference (16-20 AWG vs. 14-22 AWG)?

A: The substitute part's broader wire gauge range (14-22 AWG) encompasses the original specification (16-20 AWG). This expanded range does not compromise compatibility; it provides additional flexibility for applications within the original gauge specification.

Q: Does the "Varies by Wire Size" entry count for the Molex part affect compatibility?

A: No. This parameter indicates that the number of wire entries adapts based on the wire gauge being terminated. For 16-20 AWG applications, the Molex connector maintains single wire entry configuration, matching the original P73-D specification.

Q: Are there compliance differences between the original and substitute parts?

A: The substitute part (Molex 0191600041) carries ROHS3 compliance certification and REACH unaffected status, representing current regulatory standards. Both parts maintain identical ECCN and HTSUS classifications, confirming equivalent trade compliance.

Q: What packaging format is available for the Molex substitute?

A: The Molex 0191600041 is supplied in bulk packaging, differing from the original part's unspecified packaging format. Bulk packaging is standard for this component category and does not affect functional compatibility.

Q: Is the orange color coding consistent between both parts?

A: Yes. Both the Panduit P73-D and Molex 0191600041 feature orange color designation, maintaining industry-standard wire gauge identification and visual consistency in system installations.
