AFD57-14-4PN Equivalent & Substitute Parts

Part Overview

The AFD57-14-4PN is a 4-position circular connector plug manufactured by TE Connectivity Deutsch Connectors, designed for applications requiring MIL-DTL-26482 G Series II compliance. This male pin connector features crimp termination, bayonet lock fastening, and gold-plated mating contacts suitable for aviation, automotive, and military environments.

The AFD57-14-4PN is discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain supply chain continuity for applications requiring compatible 4-position circular connectors with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD57-14-4PN is based on the following critical parameters that must align between the main part and substitute candidates:

Mandatory Matching Parameters:

• Number of Positions: 4
• Shell Size - Insert: 14-4
• Fastening Type: Bayonet Lock
• Mounting Type: Free Hanging (In-Line)
• Orientation: N (Normal)
• Operating Temperature Range: -55°C ~ 200°C
• Termination Method: Crimp
• Ingress Protection: Environment Resistant

The substitute part PV76W14-4PL meets all mandatory matching parameters. However, this part is classified as a plug housing for male pins rather than a complete male pin connector assembly. The substitute includes a coupling nut and requires separate contact procurement, whereas the AFD57-14-4PN is a complete plug assembly with integrated male pins.

Parameter Comparison

Engineering Selection Recommendations

AFD57-14-4PN (Main Part): The AFD57-14-4PN is discontinued at DiGi Electronics. Current inventory of 754 pieces is available as new original stock. This part is RoHS non-compliant and carries EAR99 export classification. The connector is shielded with gold-plated mating contacts and nickel shell finish.

PV76W14-4PL (Substitute): The PV76W14-4PL is an active product with 812 pieces in new original stock inventory. This part is also RoHS non-compliant with EAR99 export classification. The substitute is an unshielded plug housing designed for male pins and includes a coupling nut. Contacts are not included with this part and must be procured separately.

Key Differences: The PV76W14-4PL differs from the AFD57-14-4PN in three significant aspects: (1) it is a housing-only component requiring separate contact assembly, (2) it is unshielded whereas the main part is shielded, and (3) the shell finish is chromate over cadmium rather than nickel. These differences require evaluation against specific application requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can PV76W14-4PL directly replace AFD57-14-4PN in existing assemblies?

A: Direct replacement is not possible without additional assembly work. The PV76W14-4PL is a plug housing only and does not include male pins. The AFD57-14-4PN is a complete plug assembly with integrated male pins. Substitution requires procurement of compatible crimp contacts and assembly into the PV76W14-4PL housing.

Q: What are the critical matching parameters for 4-position circular connector substitution?

A: The following parameters must match for substitution compatibility: number of positions (4), shell size-insert (14-4), fastening type (bayonet lock), mounting type (free hanging in-line), orientation (N/normal), operating temperature range (-55°C to 200°C), termination method (crimp), and ingress protection (environment resistant).

Q: Does the PV76W14-4PL provide equivalent shielding performance?

A: No. The PV76W14-4PL is unshielded, whereas the AFD57-14-4PN is shielded. Applications requiring electromagnetic interference protection or shielding performance must account for this difference.

Q: Are both parts RoHS compliant?

A: No. Both the AFD57-14-4PN and PV76W14-4PL are RoHS non-compliant. Both parts carry EAR99 export classification.

Q: What is the contact finish difference between these parts?

A: The AFD57-14-4PN specifies gold-plated mating contacts. The PV76W14-4PL contact finish is not specified in the available data, as this part is a housing-only component without integrated contacts.

Q: What is the difference in shell finish between these connectors?

A: The AFD57-14-4PN has a nickel shell finish. The PV76W14-4PL has a chromate over cadmium shell finish. These finishes provide different corrosion resistance and environmental protection characteristics.

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

A: The AFD57-14-4PN is explicitly rated for aviation, automotive, and military applications. The PV76W14-4PL application suitability is not specified in the available data.
