WTKVA44PSY

Overview

The WTKVA44PSY is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features 44 positions in a 2-row configuration with male pin contacts. Designed for cable mounting, it utilizes crimp termination and gold-plated copper alloy contacts. The housing is constructed from Polyphenylene Sulfide (PPS), supporting a current rating of 5 A and an insulation resistance of 5 GOhms. Operating temperatures range from -65 C to +125 C with a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 standards for rugged military applications
• Gold-plated contacts ensure reliable signal transmission in harsh environments
• Polyphenylene Sulfide housing provides high thermal stability and durability

Applications

• Military avionics systems requiring robust interconnects
• Ruggedized ground-based communication equipment
• Aerospace electronic assemblies demanding high reliability

Procurement Notes

Verify the specific suffix code against official Molex/AirBorn documentation to confirm exact contact plating thickness and environmental sealing requirements. Confirm that the crimp tooling matches the specified wire gauge for proper termination integrity. Ensure compatibility with mating receptacles within the same W Series family before finalizing procurement orders.

Selection Notes

Select this component when a straight, cable-mounted plug with 44 positions is required. Verify that the 5 A current rating aligns with circuit load requirements. Ensure the PCB or panel layout accommodates the 2.54 mm pitch and straight orientation constraints defined by the series specifications.

Part Context

This part belongs to the AirBorn W Series, a line of high-reliability connectors designed for severe environments. The series offers various configurations including plugs and receptacles with different row counts and termination styles, widely used in defense and aerospace sectors where vibration and temperature extremes are prevalent.

Replacement Considerations

Direct substitutes include parts sharing the MIL-DTL-55302 designation and identical 44-position, 2-row geometry. Cross-reference mating counterparts within the W Series to ensure mechanical fit and electrical continuity without modifying existing harness designs.
