Key Parameters

Substitute Part Grouping Explanation

Substitute parts PV74L14-4PL and PV74W14-4PL are classified as equivalent alternatives based on the following critical parameters:

Matching Electrical and Mechanical Specifications:

• 4-position circular connector configuration
• Shell size 14-4 (identical insert dimensions)
• Panel mount with bulkhead front side nut mounting feature
• Bayonet lock fastening mechanism
• Crimp contact termination with contact size 12
• Operating temperature range -55°C to 200°C
• Environment resistant ingress protection
• Aluminum alloy shell material
• Plastic insert material
• Unshielded design
• Normal (N) orientation

Substitution Basis: The PV74L and PV74W series receptacle housings are designed to accept the same contact size and pin configuration as the AFD54-14-4PN. Both substitute parts are receptacle housings for male pins, maintaining mechanical and electrical compatibility within the MIL-DTL-26482 circular connector family. The primary differences are shell finish specifications and housing color, which do not affect functional compatibility in applications where the connector interfaces with standard male plug assemblies.

Parameter Comparison

Engineering Selection Recommendations

PV74L14-4PL Selection: The PV74L14-4PL is an active product from ITT Cannon, LLC with electroless nickel shell finish and silver housing color. This substitute maintains full mechanical and electrical compatibility with the AFD54-14-4PN across all critical parameters. The electroless nickel finish provides corrosion resistance suitable for aviation and automotive applications. This part is recommended for applications where the original AFD54-14-4PN specification can be satisfied by equivalent housing and contact configuration.

PV74W14-4PL Selection: The PV74W14-4PL is an active product from ITT Cannon, LLC with chromate over cadmium shell finish and olive drab housing color. This substitute is functionally equivalent to the AFD54-14-4PN and is specifically suited for military applications where olive drab color coding and chromate over cadmium finish are specified. The chromate over cadmium finish provides enhanced corrosion protection in harsh military environments.

Compliance Considerations: Both substitute parts maintain RoHS non-compliant status consistent with the original AFD54-14-4PN, ensuring regulatory alignment for applications where RoHS exemptions apply. Both substitutes carry ECCN EAR99 classification, matching the export control status of the original part.

Inventory Availability: PV74L14-4PL: 1127 pieces in stock PV74W14-4PL: 987 pieces in stock

Both substitutes are available in active production status, ensuring long-term supply continuity compared to the discontinued AFD54-14-4PN.

Frequently Asked Questions (FAQ)

Q: Are PV74L14-4PL and PV74W14-4PL fully compatible with AFD54-14-4PN?

A: Yes. Both substitute parts are compatible based on matching shell size (14-4), position count (4), mounting configuration (panel mount bulkhead), fastening type (bayonet lock), termination method (crimp), and operating temperature range (-55°C to 200°C). The receptacle housings accept the same contact size and pin configuration.

Q: What is the difference between PV74L14-4PL and PV74W14-4PL?

A: The primary differences are shell finish and housing color. PV74L14-4PL features electroless nickel finish with silver housing, while PV74W14-4PL features chromate over cadmium finish with olive drab housing. Both provide equivalent electrical and mechanical performance. Selection depends on application requirements for corrosion resistance and color coding specifications.

Q: Why do the substitute parts specify "Contacts Not Included"?

A: PV74L14-4PL and PV74W14-4PL are receptacle housings supplied without pre-installed contacts. Contacts must be procured separately and crimped into the housing. The AFD54-14-4PN specification indicates a complete assembly with male pins and gold-plated crimp contacts. Ensure compatible contact specifications are selected for the substitute housing.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Mechanical interchangeability is confirmed for panel mount applications with bayonet lock mating. Electrical interchangeability depends on contact specifications. If the original AFD54-14-4PN assembly includes specific contact types or plating specifications, equivalent contacts must be selected for the substitute housing to maintain electrical performance.

Q: Are there temperature or environmental limitations for these substitutes?

A: All three parts operate across -55°C to 200°C and provide environment resistant ingress protection. No additional environmental limitations apply to the substitute parts compared to the original AFD54-14-4PN.

Q: What is the significance of the shell finish differences?

A: Electroless nickel (PV74L14-4PL) provides uniform corrosion resistance and is suitable for general aviation and automotive applications. Chromate over cadmium (PV74W14-4PL) provides enhanced corrosion protection and is specified for military applications. Selection depends on environmental exposure and application specifications.

Q: Are these parts RoHS compliant?

A: No. All three parts, including the original AFD54-14-4PN and both substitutes, are RoHS non-compliant. This status is consistent across all options and does not affect substitution eligibility for applications where RoHS exemptions apply.
