WTDXA20SAJTB

Overview

The WTDXA20SAJTB is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a cable mount receptacle with 20 positions arranged in two rows. The component utilizes crimp termination for 22 AWG wire and features gold-plated copper alloy socket contacts. Constructed with a Polyphenylene Sulfide (PPS) housing, it operates within a temperature range of -65°C to +125°C. Electrical specifications include a 5 A current rating, 1 kV voltage rating, and 5 GOhms insulation resistance at a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 standards for military-grade reliability
• Features removable crimp contacts for simplified assembly and maintenance
• Utilizes high-performance PPS housing material for thermal stability

Applications

• Avionics interconnection systems
• Military communication equipment
• Radar system signal routing

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact contact orientation and housing variations. Ensure compatibility with mating plugs regarding locking mechanisms and mounting hardware. Confirm RoHS compliance status through manufacturer certificates prior to integration into regulated assemblies.

Selection Notes

Select this model for applications requiring straight cable termination with a 2.54 mm pitch. Verify that the 22 AWG wire gauge matches the design requirements. Ensure the operating environment stays within the specified -65°C to +125°C range and that the 5 A current capacity meets circuit demands.

Part Context

This component belongs to the AirBorn W Series, designed for high-density interconnects in demanding environments. The series offers various position counts and termination styles. The WTDXA20SAJTB specifically addresses needs for robust, shielded, or unshielded cable-to-cable connections in aerospace and defense sectors.

Replacement Considerations

Check for direct equivalents within the same W Series family with different position counts if pinout flexibility is required. Verify cross-compatibility with other manufacturers' MIL-DTL-55302 connectors only if mechanical dimensions and electrical ratings are identical.
