Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD57-12-3PN is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Shell size designation (12-3) must match exactly
• Mounting type must be Free Hanging (In-Line)
• Fastening type must be Bayonet Lock
• Orientation must be Normal (N)

Electrical Compatibility:

• Number of positions must be 3
• Current rating must support 13A minimum
• Operating temperature range must encompass -55°C to 200°C
• Contact material must be copper alloy or equivalent

Environmental & Compliance:

• Ingress protection classification must be Environment Resistant
• RoHS status alignment for regulatory requirements
• Moisture sensitivity level (MSL) must be 1 or lower

The substitute part PV76W12-3PL meets these criteria as a plug housing assembly for 3-position male pin connectors with identical shell size, mounting configuration, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The AFD57-12-3PN is discontinued at DiGi Electronics. The PV76W12-3PL is listed as Active, providing ongoing availability for new procurement and long-term supply chain stability.

Compliance Alignment: Both parts are RoHS non-compliant and carry identical MSL ratings (1), ensuring regulatory consistency in applications where legacy compliance requirements apply. Both are classified under EAR99 for export control purposes.

Structural Compatibility: The PV76W12-3PL is a plug housing assembly designed specifically for 3-position male pin connectors. When paired with appropriate male pin contacts, it provides mechanical and electrical equivalence to the AFD57-12-3PN. The identical shell size (12-3), bayonet lock fastening, and free-hanging in-line mounting ensure direct mechanical interchangeability.

Environmental Performance: Both connectors operate across the full -55°C to 200°C temperature range and provide environment-resistant ingress protection, supporting deployment in aviation, automotive, and military applications.

Frequently Asked Questions (FAQ)

Q: Can the PV76W12-3PL directly replace the AFD57-12-3PN in existing assemblies?

A: The PV76W12-3PL is a plug housing assembly, whereas the AFD57-12-3PN is a complete plug with male pins. Direct substitution requires that the PV76W12-3PL be populated with appropriate male pin contacts. The housing itself is mechanically and electrically compatible due to matching shell size (12-3), bayonet lock fastening, and mounting configuration.

Q: What is the difference between the shell finishes (Nickel vs. Chromate over Cadmium)?

A: The AFD57-12-3PN features a nickel shell finish, while the PV76W12-3PL uses chromate over cadmium. Both finishes provide corrosion resistance suitable for environment-resistant applications. Selection between them depends on specific environmental exposure requirements and existing system specifications.

Q: Are the contact materials compatible?

A: Both parts use copper alloy contacts, ensuring electrical compatibility. The AFD57-12-3PN specifies gold plating on mating contacts, while the PV76W12-3PL contact specifications are determined by the individual male pin contacts installed in the housing.

Q: What is the significance of the "Contacts Not Included" note for the PV76W12-3PL?

A: The PV76W12-3PL is supplied as a housing assembly only. Male pin contacts must be sourced separately and crimped into the housing. This modular approach allows flexibility in contact selection while maintaining housing compatibility.

Q: Do both parts support the same current rating?

A: The AFD57-12-3PN is rated for 13A. The PV76W12-3PL current rating is determined by the male pin contacts installed in the housing. Ensure selected contacts support the required 13A current specification.

Q: Are there any packaging differences between the two parts?

A: The AFD57-12-3PN is packaged in standard format with 790 pieces in stock. The PV76W12-3PL is supplied in bulk packaging with 915 pieces available. Both are new original stock.

Q: Which part should be selected for new designs?

A: The PV76W12-3PL is recommended for new designs due to its Active product status, ensuring long-term availability and supply chain continuity. The AFD57-12-3PN, being discontinued, is suitable only for legacy system maintenance or replacement applications.
