Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-20-41SN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 41
• Shell Size - Insert: 20-41
• Mounting Type: Free Hanging (In-Line)
• Termination: Crimp
• Fastening Type: Bayonet Lock
• Orientation: N (Normal)
• Operating Temperature Range: -55°C ~ 200°C
• Ingress Protection: Environment Resistant

All substitute parts listed (PV75L20-41SL, PV75W20-41S, PV75W20-41SL, PV76L20-41SL, PV76W20-41SL) meet these core electrical and mechanical parameters. Variations exist in shell finish, housing color, and shielding configuration, which are secondary characteristics that do not affect functional interchangeability for the specified application requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the AFD56-20-41SN based on core electrical and mechanical parameters. Selection among the available substitutes should be based on the following criteria:

Product Status: All substitute parts (PV75L20-41SL, PV75W20-41S, PV75W20-41SL, PV76L20-41SL, PV76W20-41SL) maintain active product status with ITT Cannon, LLC, ensuring ongoing availability and supply chain continuity.

Compliance and Certification: All parts share identical RoHS non-compliance status and MSL rating (1 - Unlimited), maintaining consistency with the original AFD56-20-41SN specification.

Shell Finish Considerations: The AFD56-20-41SN features nickel plating. Substitute parts offer either electroless nickel (PV75L20-41SL, PV76L20-41SL) or chromate over cadmium finishes (PV75W20-41SL, PV76W20-41SL). Selection should align with existing system specifications and environmental exposure requirements.

Shielding Configuration: PV75L20-41SL and PV75W20-41SL provide shielded configurations, while PV76L20-41SL and PV76W20-41SL are unshielded. Shielding selection depends on electromagnetic interference requirements of the application.

Housing Color: Silver-colored housings (PV75L20-41SL, PV76L20-41SL) match the original AFD56-20-41SN. Olive drab variants (PV75W20-41SL, PV76W20-41SL) are available for applications requiring specific color coding or environmental specifications.

Data Completeness: PV75W20-41S contains incomplete technical specifications and should be selected only when full parameter documentation is not required for the application.

Frequently Asked Questions (FAQ)

Q: Can I directly replace an AFD56-20-41SN with any of the listed substitute parts?

A: Yes, all listed substitute parts meet the core electrical and mechanical parameters required for functional equivalence: 41 positions, 20-41 shell size, free-hanging in-line mounting, crimp termination, bayonet lock fastening, and -55°C to 200°C operating temperature range. Selection among substitutes depends on secondary characteristics such as shell finish, housing color, and shielding configuration.

Q: What is the difference between shielded and unshielded variants?

A: PV75L20-41SL and PV75W20-41SL incorporate shielding features, while PV76L20-41SL and PV76W20-41SL are unshielded. Shielding provides electromagnetic interference protection. Selection should be based on the electromagnetic environment and noise immunity requirements of your specific application.

Q: Are there differences in shell finish between the substitute parts?

A: Yes. The AFD56-20-41SN features nickel plating. Substitute parts offer electroless nickel finish (PV75L20-41SL, PV76L20-41SL) or chromate over cadmium finish (PV75W20-41SL, PV76W20-41SL). Finish selection should consider corrosion resistance requirements and compatibility with existing system specifications.

Q: What does "Plug Housing" mean for the substitute parts?

A: The substitute parts are classified as plug housings designed for female sockets. This designation indicates they are compatible with the mating interface requirements of the original AFD56-20-41SN specification.

Q: Why do some substitute parts show incomplete specifications?

A: PV75W20-41S contains limited technical documentation in the available data. This part maintains active product status and meets the core 41-position, 20-41 shell size, and free-hanging in-line mounting requirements. Complete specifications should be obtained directly from ITT Cannon, LLC for detailed design validation.

Q: Are all substitute parts RoHS compliant?

A: No. All substitute parts, including the original AFD56-20-41SN, are RoHS non-compliant. This status is consistent across all options and should be considered in system-level compliance assessments.

Q: What is the MSL rating and why is it important?

A: All parts carry MSL rating 1 (Unlimited), indicating unlimited shelf life without moisture sensitivity concerns. This rating ensures consistent handling and storage requirements across all substitute options.

Q: How do I choose between silver and olive drab housing colors?

A: Silver-colored housings (PV75L20-41SL, PV76L20-41SL) match the original AFD56-20-41SN appearance. Olive drab variants (PV75W20-41SL, PV76W20-41SL) are typically specified for military or specific environmental applications. Selection should align with system documentation and color-coding requirements.

Q: Are contacts included with the substitute parts?

A: No. All substitute parts are supplied as housings without contacts. Contacts must be procured separately and crimped according to the connector specification and application requirements.
