AFD57-20-41SN Equivalent & Substitute Parts

Part Overview

The AFD57-20-41SN is a 41-position circular connector plug with female sockets manufactured by TE Connectivity Deutsch Connectors. This connector features crimp termination, bayonet lock fastening, and operates across the temperature range of -55°C to 200°C. The part is designed for applications in aviation, automotive, and military environments with shielded construction and gold-plated mating contacts.

The AFD57-20-41SN is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from ITT Cannon, LLC in the PV series, which maintain compatibility with the core electrical and mechanical specifications required for direct replacement in existing assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the AFD57-20-41SN is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Functional Equivalence Parameters:

• Connector Type: Plug Housing for Female Sockets
• Shell Material: Aluminum Alloy
• Contact Type: Crimp, Contact Size 20
• Contact Shape: Circular

The substitute parts from ITT Cannon, LLC (PV series) maintain these core specifications. Variations in shell finish (Electroless Nickel versus Chromate over Cadmium) and shielding configuration (Shielded versus Unshielded) represent design alternatives within the same mechanical and electrical envelope. The PV series connectors are available in active production status, ensuring long-term supply availability compared to the discontinued AFD57-20-41SN.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes for Shielded Applications:

PV75L20-41SL and PV75W20-41SL are direct functional equivalents for applications requiring shielded construction. Both maintain the shielded configuration of the original AFD57-20-41SN. PV75L20-41SL features Electroless Nickel finish with silver housing, while PV75W20-41SL features Chromate over Cadmium finish with olive drab housing. Selection between these two depends on environmental exposure and finish compatibility with existing system specifications.

Alternative Substitutes for Unshielded Applications:

PV76L20-41SL and PV76W20-41SL provide unshielded alternatives with identical mechanical and electrical specifications. These parts are suitable for applications where EMI shielding is not required. PV76L20-41SL offers Electroless Nickel finish with silver housing, while PV76W20-41SL provides Chromate over Cadmium finish with olive drab housing.

Product Status Consideration:

All substitute parts from ITT Cannon, LLC maintain active production status, ensuring availability for new designs and replacement requirements. The AFD57-20-41SN discontinuation status necessitates transition to one of these active alternatives for long-term supply chain continuity.

Compliance and Certification:

All listed parts, including the original AFD57-20-41SN and all substitutes, carry RoHS non-compliant status and MSL Rating 1 (Unlimited). ECCN classification is EAR99 for all parts. These compliance parameters remain consistent across all substitution options.

Frequently Asked Questions (FAQ)

Q: Can PV76L20-41SL or PV76W20-41SL be used as direct replacements for AFD57-20-41SN in shielded applications?

A: No. The PV76 series connectors are unshielded, while the AFD57-20-41SN is shielded. For applications requiring shielded construction, use PV75L20-41SL or PV75W20-41SL instead.

Q: What is the difference between PV75L20-41SL and PV75W20-41SL?

A: Both are shielded 41-position connectors with identical mechanical and electrical specifications. The primary differences are shell finish (Electroless Nickel versus Chromate over Cadmium) and housing color (Silver versus Olive Drab). Selection depends on environmental exposure requirements and system finish specifications.

Q: Do the PV series connectors include contacts?

A: No. The PV series substitute parts are plug housings supplied without contacts. Contacts must be procured separately and crimped into the housing. The original AFD57-20-41SN specification should be consulted for compatible contact part numbers.

Q: Are all substitute parts available in the same quantities as the discontinued AFD57-20-41SN?

A: Current inventory levels vary. PV76L20-41SL has 1023 pieces in stock, PV75W20-41SL has 1004 pieces, PV75L20-41SL has 927 pieces, and PV76W20-41SL has 866 pieces. Inventory status should be confirmed at time of procurement.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across -55°C to 200°C, matching the original AFD57-20-41SN specification.

Q: Are there any differences in the bayonet lock fastening mechanism between the original and substitute parts?

A: No. All substitute parts use bayonet lock fastening identical to the AFD57-20-41SN, ensuring mechanical compatibility with mating connectors.

Q: Can I mix shielded and unshielded connectors in the same assembly?

A: This depends on system design requirements. Shielded connectors (PV75 series) provide EMI protection, while unshielded connectors (PV76 series) do not. System specifications should determine whether uniform shielding is required throughout the assembly.
