WTDXA20SJ

Overview

The WTDXA20SJ is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features a 20-position, 2-row configuration with female socket contacts. The component utilizes a crimp termination method and is designed for PCB mount installation in a straight orientation. Contacts are gold-plated copper alloy, while the housing is constructed from Polyphenylene Sulfide (PPS). Key electrical ratings include a 5 A current capacity, 1 kV voltage rating, and 5 GOhms insulation resistance. It operates within a temperature range of -65 C to +125 C, supports 22 AWG wire, and maintains a 2.54 mm pitch.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for rugged performance
• Features gold-plated copper alloy contacts for reliable signal transmission
• Constructed with Polyphenylene Sulfide housing for thermal stability

Applications

• Military aerospace electronic systems
• Ruggedized industrial control interfaces
• High-reliability communication equipment

Procurement Notes

Verify the complete part number suffix against official Molex documentation, as variations such as WTDXA20SJTB or WTDXA20SJTB-C45 indicate specific packaging or certification differences. Confirm RoHS compliance status and availability through authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required crimp termination and PCB mounting style for your design.

Selection Notes

Select this component when a 20-position, 2-row receptacle is required for board-level interconnects. Ensure the design accommodates the 2.54 mm pitch and 22 AWG wire gauge constraints. Verify that the straight PCB mount style aligns with the enclosure layout. Consider the 125 C maximum operating temperature for high-heat environments.

Part Context

This connector belongs to the AirBorn W Series, a line of rectangular MIL-Spec connectors known for durability. The series offers various position counts and termination styles, all sharing common electrical ratings and material properties. The WTDXA20SJ specifically addresses applications needing robust, high-density connections in demanding environments.

Replacement Considerations

Check for equivalents under MIL-DTL-55302. Cross-reference with other W Series variants if position count differs. Verify pinout compatibility before substituting.
