Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-14-4PN is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Shell size designation (14-4) must match exactly
• Mounting type must be Free Hanging (In-Line)
• Fastening type must be Bayonet Lock
• Orientation must be N (Normal)
• Number of positions must be 4

Electrical Compatibility:

• Termination method must be Crimp
• Current rating must support 23A minimum
• Operating temperature range must encompass -55°C to 200°C

Material & Environmental:

• Shell material must be aluminum or aluminum alloy
• Ingress protection must be Environment Resistant
• Moisture sensitivity level must be 1 (Unlimited)

The substitute part PV76W14-4PL meets all critical parameters for mechanical and electrical interchangeability within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

The PV76W14-4PL manufactured by ITT Cannon, LLC serves as a direct functional substitute for the discontinued AFD56-14-4PN. Both connectors maintain identical shell size, position count, mounting configuration, and operating temperature specifications. The substitute part is currently in active production status with 812 pieces available in inventory, providing supply continuity for applications requiring 4-position circular connectors with bayonet lock fastening.

Both parts carry identical RoHS non-compliance status and moisture sensitivity ratings, ensuring consistent regulatory and environmental handling requirements across component selection. The substitute maintains the same current rating capacity and crimp termination methodology, supporting direct integration into existing harness designs without modification to contact specifications or assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the PV76W14-4PL directly replace the AFD56-14-4PN in existing assemblies?

A: Yes. Both connectors share identical shell size (14-4), position count (4), mounting type (Free Hanging In-Line), fastening mechanism (Bayonet Lock), and operating temperature range (-55°C to 200°C). The crimp termination method and current rating are equivalent, enabling direct substitution without assembly modification.

Q: What is the primary difference between these two connector models?

A: The AFD56-14-4PN is a complete plug assembly with male pins, while the PV76W14-4PL is a plug housing designed to accept male pins. The PV76W14-4PL requires separate contact assembly, whereas the AFD56-14-4PN includes integrated male pins. Both achieve the same functional interface when properly assembled.

Q: Are there any material or finish differences that affect compatibility?

A: The AFD56-14-4PN features nickel-finished aluminum shell with gold-plated mating contacts. The PV76W14-4PL features chromate over cadmium finish on aluminum alloy shell. Both materials provide equivalent environmental resistance and operate across the same temperature range. Contact finish specifications must be verified during contact selection for the PV76W14-4PL housing.

Q: What is the significance of the shell size designation "14-4"?

A: The "14-4" designation indicates a size 14 shell with 4 positions. This is a critical mechanical parameter that determines physical fit and mating compatibility. Both the main part and substitute share this designation, ensuring mechanical interchangeability.

Q: Why is the AFD56-14-4PN listed as discontinued?

A: The AFD56-14-4PN is discontinued at DiGi Electronics, indicating it is no longer available through this distribution channel. The PV76W14-4PL remains in active production, providing an available alternative for new designs and replacement applications.

Q: Are both connectors suitable for aviation, automotive, and military applications?

A: The AFD56-14-4PN is specified for aviation, automotive, and military applications. The PV76W14-4PL, as a housing component within the PV series, is designed for equivalent industrial and military environments. Application suitability must be confirmed against specific system requirements and qualification standards.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Components can be stored and handled without desiccant packaging or time-limited shelf life constraints, simplifying inventory management and logistics.
