WTA20PW40JTB

Overview

The WTA20PW40JTB is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features 20 positions arranged in two rows with a 2.54 mm pitch. The plug utilizes male pin contacts made of copper alloy with gold plating. Termination is achieved via solder cup connections designed for 22 AWG wire. The housing is constructed from Polyphenylene Sulfide (PPS). Electrical ratings include a current capacity of 5 A and an insulation resistance of 5 GOhms. It operates within a temperature range of -65 C to +125 C.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 standards
• Gold-plated copper alloy pin contacts for reliable signal transmission
• Polyphenylene Sulfide (PPS) housing material for thermal stability

Applications

• Avionics control systems
• Radar equipment interconnects
• Electronic warfare modules

Procurement Notes

Verify the specific suffix JTB against official Molex/AirBorn documentation to confirm termination style and mounting configuration. Ensure compatibility with mating receptacles within the W Series family. Confirm RoHS compliance status through current manufacturer certificates before integration into regulated assemblies.

Selection Notes

Select this component when a straight, free-hanging or board-mountable plug with solder cup terminations is required. The 20-position density suits applications needing moderate I/O counts. Verify that the 5 A current rating and PPS thermal limits align with the system's operational environment and wiring gauge requirements.

Part Context

This part belongs to the AirBorn W Series, a line of high-reliability connectors widely used in defense and aerospace sectors. The series offers various contact densities and termination options to meet stringent environmental and mechanical stress requirements typical of military platforms.

Replacement Considerations

Cross-reference with M55302 equivalents. Verify physical dimensions and contact alignment with existing mating hardware to ensure interchangeability without modification.
