Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-12-3PN is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Number of positions: 3
• Shell size designation: 12-3
• Mounting configuration: Free Hanging (In-Line)
• Fastening mechanism: Bayonet Lock
• Connector orientation: N (Normal)

Electrical Compatibility:

• Termination method: Crimp
• Current rating: 13A
• Operating temperature range: -55°C ~ 200°C
• Contact material: Copper Alloy

Environmental & Regulatory:

• Ingress protection classification: Environment Resistant
• Material composition: Aluminum shell with appropriate finishes

The substitute part PV76W12-3PL satisfies all mechanical and electrical compatibility requirements. However, differences in shell finish, contact finish, and regulatory compliance status must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Regulatory Compliance

The AFD56-12-3PN is ROHS3 compliant and REACH affected. The substitute part PV76W12-3PL is RoHS non-compliant. Applications subject to RoHS3 or REACH regulatory requirements cannot use PV76W12-3PL as a direct replacement without regulatory review and approval.

Secondary Consideration: Product Availability

The AFD56-12-3PN is discontinued at DiGi Electronics. The PV76W12-3PL maintains active product status with 915 units in stock, providing supply chain continuity for applications where regulatory constraints do not apply.

Material & Finish Differences

The AFD56-12-3PN features nickel shell finish with gold contact finish. The PV76W12-3PL features chromate over cadmium shell finish. These finish differences may affect corrosion resistance and contact performance in specific environmental conditions. Applications requiring specific corrosion resistance profiles must account for these material variations.

Connector Assembly Consideration

The PV76W12-3PL is specified as a plug housing without included contacts. The AFD56-12-3PN is a complete plug assembly with male pins. Substitution requires separate procurement and assembly of appropriate crimp contacts.

Frequently Asked Questions (FAQ)

Q: Can PV76W12-3PL directly replace AFD56-12-3PN in all applications?

A: No. Direct replacement is limited to applications without RoHS3 or REACH compliance requirements. The PV76W12-3PL is RoHS non-compliant, which restricts its use in regulated environments. Additionally, PV76W12-3PL is a housing-only component requiring separate contact procurement and assembly.

Q: What are the critical mechanical compatibility factors?

A: Both connectors share identical mechanical specifications: 3-position configuration, 12-3 shell size, bayonet lock fastening, free hanging in-line mounting, and normal orientation. These parameters ensure physical mating compatibility.

Q: How do the shell finishes affect performance?

A: The AFD56-12-3PN uses nickel finish; the PV76W12-3PL uses chromate over cadmium finish. Nickel provides superior corrosion resistance in most industrial environments. Chromate over cadmium offers different corrosion characteristics and may be restricted in certain applications due to cadmium content regulations.

Q: Are the contact materials equivalent?

A: Both connectors use copper alloy contacts. The AFD56-12-3PN specifies gold mating finish; the PV76W12-3PL contact finish is not specified. Gold finish provides superior electrical conductivity and corrosion resistance compared to unspecified finishes.

Q: What is the significance of the PV76W12-3PL being a housing-only component?

A: The PV76W12-3PL requires separate procurement of crimp contacts and assembly operations. The AFD56-12-3PN is a complete plug assembly ready for installation. Substitution requires additional procurement steps and assembly labor.

Q: Do both connectors support the same current rating?

A: The AFD56-12-3PN is rated for 13A. The PV76W12-3PL current rating is not specified in available documentation. Applications with defined current requirements must verify PV76W12-3PL specifications through the manufacturer.

Q: What temperature range compatibility exists?

A: Both connectors operate across -55°C to 200°C, providing equivalent thermal performance for temperature-dependent applications.
