WTDXA30SJTA

Overview

The WTDXA30SJTA is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a receptacle with 30 positions arranged in two rows. The component utilizes socket contacts made of copper alloy with gold plating, terminated via crimp connections for 22 AWG wire. Designed for board mounting, it features a straight orientation and a Polyphenylene Sulfide (PPS) housing. Electrical ratings include a current capacity of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -65 C to +125 C, with a contact pitch of 2.54 mm.

Feature Summary

• Compliant with MIL-DTL-55302 standards for military-grade reliability
• Gold-plated copper alloy socket contacts ensure durable signal transmission
• Polyphenylene Sulfide housing provides thermal stability and chemical resistance

Applications

• Military avionics systems requiring high-reliability interconnects
• Ruggedized electronic equipment operating in extreme temperatures
• Board-to-board or cable-to-board connections in defense applications

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to confirm termination type and housing variations. Ensure compatibility with mating plugs within the W Series family. Confirm that the crimp tooling matches the specified 22 AWG wire gauge requirements for proper assembly and performance validation.

Selection Notes

Select this part when a 30-position, dual-row receptacle is required for MIL-DTL-55302 applications. Choose the crimp termination variant if pre-assembled cables are preferred over through-hole soldering. Verify that the 2.54 mm pitch and straight mounting style align with the PCB layout constraints and available panel space.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The series offers various position counts and termination options, maintaining consistent form factors across the family. The WTDXA30SJTA specifically addresses needs for medium-density interconnects with robust mechanical and electrical specifications.

Replacement Considerations

Check for direct equivalents such as M55302/66-30H if cross-referencing legacy designations. Ensure any substitute maintains the same 30-position count, socket contact gender, and crimp termination method to preserve mechanical fit and electrical continuity.
