AFD57-18-8PN Equivalent & Substitute Parts

Part Overview

The AFD57-18-8PN is an 8-position circular connector plug with male pins manufactured by TE Connectivity Deutsch Connectors. This connector features crimp termination, bayonet lock fastening, and is designed for free-hanging in-line mounting applications. The part conforms to MIL-DTL-26482 G Series II specifications and is rated for 23A current with an operating temperature range of -55°C to 200°C. The AFD57-18-8PN is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain functional and mechanical compatibility for aviation, automotive, and military applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFD57-18-8PN are identified based on strict alignment with the following critical parameters:

Mechanical Compatibility Parameters:

• Number of Positions: 8
• Shell Size - Insert: 18-8
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Orientation: N (Normal)

Electrical Compatibility Parameters:

• Termination: Crimp
• Operating Temperature: -55°C ~ 200°C
• Shielding: Shielded (for primary substitutes)

Material & Environmental Parameters:

• Shell Material: Aluminum Alloy
• Insert Material: Plastic
• Ingress Protection: Environment Resistant

The substitute parts listed are ITT Cannon, LLC PV series connector plug housings. These components maintain identical mechanical interfaces, position count, shell sizing, and mounting characteristics. The PV75L18-8PL and PV75W18-8PL variants provide shielded configurations matching the AFD57-18-8PN shielding specification. The PV76L18-8PL and PV76W18-8PL variants provide unshielded alternatives for applications where shielding is not required. All substitute parts operate within the same temperature range and utilize crimp contact termination with bayonet lock fastening.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Shielded Configuration):

The PV75L18-8PL and PV75W18-8PL are the primary substitute options for the AFD57-18-8PN. Both maintain shielded connector architecture matching the original part specification. The PV75L18-8PL features electroless nickel finish with silver housing color, while the PV75W18-8PL features chromate over cadmium finish with olive drab housing color. Selection between these two variants depends on application-specific finish and color requirements. Both parts are currently active products with substantial inventory availability (751 and 997 units respectively).

Secondary Substitutes (Unshielded Configuration):

The PV76L18-8PL and PV76W18-8PL provide unshielded alternatives for applications where electromagnetic shielding is not a functional requirement. These parts maintain all other mechanical and electrical compatibility parameters with the AFD57-18-8PN. The PV76L18-8PL offers electroless nickel finish with silver housing, while the PV76W18-8PL offers chromate over cadmium finish with olive drab housing. Both unshielded variants are active products with high inventory availability (943 and 920 units respectively).

Compliance Considerations:

All substitute parts maintain RoHS non-compliant status consistent with the original AFD57-18-8PN. All substitute parts carry EAR99 ECCN classification and are suitable for the same application domains (aviation, automotive, military). The transition from discontinued AFD57-18-8PN to active ITT Cannon PV series components ensures continued supply chain availability for replacement and new production requirements.

Frequently Asked Questions (FAQ)

Q: Can PV75L18-8PL or PV75W18-8PL be used as direct replacements for AFD57-18-8PN?

A: Yes, both PV75L18-8PL and PV75W18-8PL maintain mechanical and electrical compatibility with AFD57-18-8PN. Both preserve the shielded connector configuration, 8-position layout, 18-8 shell size, bayonet lock fastening, and -55°C to 200°C operating temperature range. The primary differences are manufacturer (ITT Cannon versus TE Connectivity Deutsch), shell finish (electroless nickel or chromate over cadmium versus nickel), and housing color (silver or olive drab versus silver).

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

A: The PV75 series (PV75L18-8PL and PV75W18-8PL) provides shielded connector housings, matching the shielded specification of the AFD57-18-8PN. The PV76 series (PV76L18-8PL and PV76W18-8PL) provides unshielded connector housings. Selection between these series depends on whether electromagnetic shielding is required for the application. All other parameters remain identical.

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

A: The "L" designation indicates electroless nickel shell finish with silver housing color. The "W" designation indicates chromate over cadmium shell finish with olive drab housing color. Both finishes provide corrosion resistance suitable for aviation, automotive, and military applications. Selection depends on application-specific finish and color requirements.

Q: Are contacts included with the PV series substitute parts?

A: No. The PV75L18-8PL, PV75W18-8PL, PV76L18-8PL, and PV76W18-8PL are connector plug housings supplied without contacts. Contacts must be sourced separately and crimped into the housing. The AFD57-18-8PN specification indicates crimp termination with contact size 12 for the PV series housings.

Q: Do all substitute parts operate within the same temperature range as AFD57-18-8PN?

A: Yes. All four substitute parts (PV75L18-8PL, PV75W18-8PL, PV76L18-8PL, and PV76W18-8PL) operate within the identical temperature range of -55°C to 200°C as the AFD57-18-8PN.

Q: What is the inventory status of substitute parts?

A: All four substitute parts are currently active products with substantial inventory availability. PV75L18-8PL has 751 units in stock, PV75W18-8PL has 997 units, PV76L18-8PL has 943 units, and PV76W18-8PL has 920 units. The AFD57-18-8PN is discontinued at DiGi Electronics with 1053 units remaining in stock.

Q: Are the substitute parts suitable for aviation, automotive, and military applications?

A: Yes. All PV series substitute parts are designated for aviation, automotive, and military applications, consistent with the AFD57-18-8PN application profile. All parts maintain RoHS non-compliant status and EAR99 ECCN classification appropriate for these application domains.
