AFD56-20-16PN Equivalent & Substitute Parts

Part Overview

The AFD56-20-16PN is a 16-position circular connector plug with male pins manufactured by TE Connectivity Deutsch Connectors. This connector is designed for crimp termination and features a bayonet lock fastening mechanism, operating across the temperature range of -55°C to 200°C. The part is classified as discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility for ongoing system support and maintenance applications in aviation, automotive, and military environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-20-16PN is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Number of Positions: 16
• Shell Size - Insert: 20-16
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Termination Method: Crimp
• Operating Temperature Range: -55°C ~ 200°C
• Ingress Protection: Environment Resistant

The substitute parts listed are ITT Cannon, LLC PV series connector plug housings (PV75L20-16PL, PV75W20-16PL, PV76L20-16PL, PV76W20-16PL) that satisfy all mandatory compatibility parameters. These substitutes are classified as plug housings for male pins rather than complete plug assemblies. The distinction between shielded (PV75 series) and unshielded (PV76 series) variants, as well as shell finish differences (electroless nickel versus chromate over cadmium), represents secondary design variations that do not affect core mechanical and electrical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (PV75L20-16PL, PV75W20-16PL, PV76L20-16PL, PV76W20-16PL) maintain active product status with ITT Cannon, LLC, providing long-term availability and supply chain continuity compared to the discontinued AFD56-20-16PN. The substitutes are functionally equivalent across all mandatory electrical and mechanical parameters specified for 16-position circular connector plugs with bayonet lock fastening and crimp termination.

Selection between substitute variants is determined by application-specific requirements:

Shielded Variants (PV75 Series): PV75L20-16PL and PV75W20-16PL incorporate shielding features and are selected for applications requiring electromagnetic interference mitigation.

Unshielded Variants (PV76 Series): PV76L20-16PL and PV76W20-16PL are selected for applications where shielding is not required.

Shell Finish Variants: Electroless nickel finish (L designation) and chromate over cadmium finish (W designation) are selected based on corrosion resistance requirements and environmental exposure conditions. Both finishes maintain equivalent mechanical and electrical performance across the specified operating temperature range.

All substitute parts share identical RoHS non-compliance status and MSL rating with the original part, ensuring consistency in compliance documentation and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can PV75L20-16PL, PV75W20-16PL, PV76L20-16PL, and PV76W20-16PL be used interchangeably with AFD56-20-16PN?

A: The substitute parts are mechanically and electrically compatible with the AFD56-20-16PN across all specified parameters including shell size, position count, mounting configuration, and operating temperature range. Selection between variants depends on shielding requirements and shell finish specifications for the intended application.

Q: What is the difference between PV75 and PV76 series substitutes?

A: The primary difference is shielding configuration. PV75 series connectors incorporate shielding, while PV76 series connectors are unshielded. Both series maintain identical mechanical compatibility, position count, shell size, and operating temperature specifications.

Q: What is the difference between L and W designations in the part numbers?

A: The L designation indicates electroless nickel shell finish, while the W designation indicates chromate over cadmium shell finish. Both finishes provide corrosion resistance and are compatible with the -55°C to 200°C operating temperature range. Selection is based on environmental exposure and corrosion resistance requirements.

Q: Are the substitute parts available in the same packaging as the original AFD56-20-16PN?

A: The substitute parts are supplied in bulk packaging. Inventory availability for all four variants is confirmed at 715 to 1018 pieces per part number.

Q: Do the substitute parts require different crimp contacts than the original AFD56-20-16PN?

A: The substitute parts are plug housings specified for male pins with crimp contact type and contact size 16. Compatibility with specific crimp contacts is determined by the contact size and crimp termination specifications common to both the original and substitute parts.

Q: What is the current rating for the substitute parts?

A: The current rating specification is not provided in the substitute part data. Verification of current rating compatibility with system requirements is necessary during component selection.

Q: Are all substitute parts RoHS compliant?

A: No. All substitute parts maintain RoHS non-compliant status consistent with the original AFD56-20-16PN, ensuring alignment with existing compliance documentation and procurement specifications.
