AFD57-8-33PN Equivalent & Substitute Parts

Part Overview

The AFD57-8-33PN is a 3-position circular connector plug with male pins manufactured by TE Connectivity Deutsch Connectors. This component is designed for applications requiring bayonet-lock coupling in aviation, automotive, and military environments. The connector features crimp termination, gold-plated mating contacts, and operates across an extended temperature range of -55°C to 200°C.

The AFD57-8-33PN has been discontinued at DiGi Electronics. Equivalent substitute parts are available from ITT Cannon, LLC, offering compatible mechanical and electrical interfaces for applications requiring replacement or redesign of existing assemblies.

Engineering Selection Recommendations

The AFD57-8-33PN has been discontinued at DiGi Electronics. Both PV76L8-33PL and PV76W8-33PL are active products from ITT Cannon, LLC, with current inventory availability.

PV76L8-33PL features an electroless nickel shell finish with silver housing color.

PV76W8-33PL features a chromate over cadmium shell finish with olive drab housing color.

Both substitute parts maintain identical mechanical compatibility, position configuration, shell sizing, and operating temperature specifications. The primary differences between the two substitutes are shell finish and housing color, which are determined by application-specific environmental and aesthetic requirements.

All three parts carry RoHS non-compliant status and MSL rating of 1 (Unlimited). The AFD57-8-33PN is shielded, while both substitute parts are unshielded. Selection between PV76L8-33PL and PV76W8-33PL should be based on finish and color requirements specific to the application environment and system integration needs.

Frequently Asked Questions (FAQ)

Q: Can PV76L8-33PL and PV76W8-33PL directly replace the AFD57-8-33PN?

A: Both ITT Cannon parts share identical mechanical interfaces, position counts, shell sizes, bayonet-lock fastening, and operating temperature ranges. The primary difference is that the AFD57-8-33PN is a complete plug assembly with male pins, while PV76L8-33PL and PV76W8-33PL are plug housings designed for male pins. Contacts are not included with the substitute parts.

Q: What is the difference between PV76L8-33PL and PV76W8-33PL?

A: Both parts are mechanically and electrically identical 3-position plug housings with 8-33 shell sizing. The differences are: PV76L8-33PL has electroless nickel finish with silver housing color; PV76W8-33PL has chromate over cadmium finish with olive drab housing color. Selection depends on environmental corrosion resistance requirements and system color specifications.

Q: Are the substitute parts shielded like the original AFD57-8-33PN?

A: No. The AFD57-8-33PN is shielded, while both PV76L8-33PL and PV76W8-33PL are unshielded. Applications requiring electromagnetic shielding must account for this difference.

Q: What is the contact size for the substitute parts?

A: Both PV76L8-33PL and PV76W8-33PL accommodate contact size 20 with crimp termination.

Q: Are all three parts RoHS compliant?

A: No. The AFD57-8-33PN, PV76L8-33PL, and PV76W8-33PL are all RoHS non-compliant. All three parts carry MSL rating of 1 (Unlimited).

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

A: The current rating for the AFD57-8-33PN is specified as 7.5A. Current rating information is not provided for PV76L8-33PL and PV76W8-33PL in the available technical data.
