Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFD57-24-19PN are identified based on strict alignment with the following critical parameters:

• Connector Configuration: 19-position circular connector with male pin orientation
• Shell Size Compatibility: 24-19 shell size and insert designation
• Mounting Architecture: Free hanging (in-line) configuration
• Termination Method: Crimp contact termination
• Fastening Mechanism: Bayonet lock coupling
• Environmental Sealing: Shielded design with environment resistant rating
• Operating Range: -55°C to 200°C temperature specification
• Contact Crimp Size: 12 (where specified)

The substitute parts PV75L24-19PL and PV75W24-19PL are ITT Cannon, LLC plug housings that satisfy these core compatibility requirements. Both substitute parts are supplied as connector housings without integrated contacts, requiring separate contact procurement for complete assembly.

Parameter Comparison

Engineering Selection Recommendations

PV75L24-19PL is an active substitute component manufactured by ITT Cannon, LLC with electroless nickel shell finish. This part maintains full mechanical and electrical compatibility with the AFD57-24-19PN across all critical parameters including shell size, position count, mounting configuration, and operating temperature range. The electroless nickel finish provides corrosion resistance suitable for aviation, automotive, and military applications. This substitute is supplied as a plug housing without integrated contacts.

PV75W24-19PL is an active substitute component manufactured by ITT Cannon, LLC with chromate over cadmium shell finish and olive drab housing color. This part satisfies identical mechanical and electrical compatibility requirements as the AFD57-24-19PN. The chromate over cadmium finish is specified for military applications requiring enhanced corrosion protection. This substitute is supplied as a plug housing without integrated contacts.

Both substitute parts are currently in active production status, ensuring long-term availability for system maintenance and new builds. Neither substitute part includes integrated contacts; separate procurement of crimp contacts (contact size 12) is required for complete connector assembly.

Frequently Asked Questions (FAQ)

Q: Can PV75L24-19PL and PV75W24-19PL be used interchangeably with AFD57-24-19PN?

A: Both substitute parts are mechanically and electrically compatible with the AFD57-24-19PN. The primary differences are shell finish (electroless nickel versus chromate over cadmium) and housing color. Selection between substitutes depends on application-specific corrosion resistance requirements and environmental exposure conditions.

Q: What is the difference between PV75L24-19PL and PV75W24-19PL?

A: Both parts share identical mechanical specifications, position count, shell size, and operating temperature range. The distinction lies in shell finish: PV75L24-19PL features electroless nickel finish with silver housing color, while PV75W24-19PL features chromate over cadmium finish with olive drab housing color. The chromate over cadmium finish is typically specified for military applications.

Q: Are contacts included with the substitute parts?

A: No. Both PV75L24-19PL and PV75W24-19PL are supplied as plug housings without integrated contacts. Crimp contacts (contact size 12) must be procured separately and crimped into the housing to complete the connector assembly.

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

A: Contact size 12 is specified for both PV75L24-19PL and PV75W24-19PL. Ensure that replacement contacts match this specification for proper fit and electrical performance.

Q: Are the substitute parts RoHS compliant?

A: No. Both PV75L24-19PL and PV75W24-19PL are RoHS non-compliant, consistent with the original AFD57-24-19PN specification. This is typical for military and aerospace-grade connectors utilizing cadmium and other restricted substances for enhanced performance characteristics.

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

A: The current rating for the original AFD57-24-19PN is 23A. The substitute parts maintain compatibility with this electrical specification through identical shell size, contact configuration, and termination method.

Q: Can the AFD57-24-19PN be mated with PV75L24-19PL or PV75W24-19PL?

A: Yes. The AFD57-24-19PN plug (male pins) is mechanically compatible with both PV75L24-19PL and PV75W24-19PL plug housings (male configuration) through the standardized 24-19 shell size and bayonet lock fastening mechanism.
