AFD56-12-8SN Equivalent & Substitute Parts

Part Overview

The AFD56-12-8SN is an 8-position circular connector plug with female sockets manufactured by TE Connectivity Deutsch Connectors. This connector is designed for free-hanging (in-line) applications and features crimp termination with bayonet lock fastening. The part is compliant with MIL-DTL-26482 G Series II specifications and is rated for 7.5A continuous current operation across an extended temperature range of -55°C to 200°C.

The AFD56-12-8SN is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent substitute components. Equivalent parts must maintain compatibility across critical electrical and mechanical parameters including connector type, position count, shell size, termination method, and operating environment specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-12-8SN is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Plug with Female Sockets)
• Number of positions (8)
• Shell size designation (12-8)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Bayonet Lock)
• Orientation (Normal)

Electrical Compatibility:

• Termination method (Crimp)
• Current rating (7.5A minimum)
• Operating temperature range (-55°C to 200°C minimum)
• Contact finish (Gold mating surface)

Environmental Compliance:

• Ingress protection classification (Environment Resistant)
• Material specifications (Aluminum shell with Nickel finish)

The substitute part PV76L12-8SL meets all mechanical and environmental parameters. However, this substitute is classified as a plug housing component and does not include contacts, requiring separate procurement of compatible crimp contacts for complete assembly.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PV76L12-8SL

The PV76L12-8SL from ITT Cannon, LLC is the identified equivalent substitute for the discontinued AFD56-12-8SN. This substitute maintains full mechanical and environmental compatibility across all critical parameters including connector type, position count, shell size, mounting configuration, and operating temperature specifications.

Product Status Advantage: The PV76L12-8SL is currently active in production and inventory, with 776 pieces available in stock, providing immediate procurement availability compared to the discontinued AFD56-12-8SN.

Compliance Consideration: The AFD56-12-8SN is ROHS3 compliant, while the PV76L12-8SL is classified as RoHS non-compliant. Applications subject to RoHS regulatory requirements must evaluate this compliance difference against project specifications.

Component Assembly Requirement: The PV76L12-8SL is supplied as a plug housing without integrated contacts. Crimp contacts must be procured separately and assembled into the housing. The substitute specifies contact size 20, which must be verified against the contact specifications of the original AFD56-12-8SN assembly.

Environmental and Electrical Performance: Both components are rated for identical operating temperature ranges (-55°C to 200°C) and provide environment-resistant ingress protection suitable for aviation, automotive, and military applications. The 7.5A current rating of the main part is maintained through the substitute's mechanical design.

Frequently Asked Questions (FAQ)

Q: Can the PV76L12-8SL directly replace the AFD56-12-8SN in existing assemblies?

A: The PV76L12-8SL housing is mechanically and electrically compatible with the AFD56-12-8SN. However, the substitute is supplied without contacts. If the original assembly includes pre-installed contacts, those contacts must be transferred or equivalent contacts (size 20) must be procured and installed in the substitute housing.

Q: What is the difference between the AFD56-12-8SN and PV76L12-8SL connector types?

A: The AFD56-12-8SN is a complete plug assembly with integrated female sockets. The PV76L12-8SL is a plug housing designed to accept separate crimp contacts. Both function as 8-position plugs with identical shell sizes and mounting configurations.

Q: Are the operating temperature ranges identical?

A: Yes. Both the AFD56-12-8SN and PV76L12-8SL are rated for -55°C to 200°C continuous operation, making them suitable for identical thermal environments.

Q: What is the significance of the contact size specification (20) for the PV76L12-8SL?

A: Contact size 20 specifies the physical dimensions and current-carrying capacity of the crimp contacts that must be installed in the PV76L12-8SL housing. This specification must be matched when procuring replacement or additional contacts.

Q: Does the RoHS compliance difference affect electrical performance?

A: RoHS compliance is a regulatory and material composition specification, not an electrical performance parameter. The RoHS non-compliance of the PV76L12-8SL does not affect its electrical characteristics. Applications subject to RoHS requirements must evaluate regulatory compliance separately from electrical compatibility.

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

A: Yes. Both the AFD56-12-8SN and PV76L12-8SL are specified for aviation, automotive, and military applications with environment-resistant ingress protection and extended temperature operation.

Q: What is the difference between Nickel and Electroless Nickel shell finishes?

A: Both finishes provide corrosion resistance and environmental protection. Electroless nickel is an alternative plating process that achieves equivalent protective characteristics. Both finishes are suitable for the specified operating environments.

Q: Can the PV76L12-8SL be used in applications requiring ROHS3 compliance?

A: No. The PV76L12-8SL is RoHS non-compliant. Applications with mandatory ROHS3 compliance requirements cannot use this substitute. Alternative compliant components must be identified for such applications.
