WRDDXA122SJTBMM

Overview

The WRDDXA122SJTBMM is a rectangular MIL Spec connector from the AirBorn W Series, manufactured by Molex. It features 122 positions arranged in four rows with a 2.54 mm pitch. The component utilizes crimp termination for 22 AWG wires and includes gold-plated copper alloy sockets. Designed for free-hanging panel mounting, it operates within a temperature range of -65°C to +125°C. The housing is constructed from Polyphenylene Sulfide (PPS), providing an insulation resistance of 5 GOhms and a current rating of 5 A.

Feature Summary

• MIL-DTL-55302 qualified military-grade construction
• High-density 122-position interconnect capability
• Corrosion-resistant gold contact plating
• Robust PPS housing for thermal stability

Applications

• Military avionics systems
• Ruggedized communication equipment
• Defense ground station interfaces
• Harsh environment data buses

Procurement Notes

Verify the specific suffix MM indicates the free-hanging panel mount configuration distinct from PCB or cable variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure mating connectors match the W Series specifications for proper alignment and electrical continuity in critical applications.

Selection Notes

Select this part for applications requiring high pin counts in constrained spaces with strict environmental durability needs. The straight orientation and panel-mount style suit chassis installations where cable entry is required. Validate that the 5A current rating per contact meets system load requirements under maximum operating temperatures.

Part Context

This component belongs to the AirBorn W Series, a line of high-performance rectangular connectors designed for demanding industrial and defense sectors. The series emphasizes reliability and density, utilizing advanced materials to withstand vibration and extreme temperatures common in aerospace and military deployments.

Replacement Considerations

Direct substitutes must match the 122-position count, 2.54 mm pitch, and MIL-DTL-55302 qualification. Verify mechanical compatibility with existing panel cutouts and mating interface standards before considering alternative manufacturers.
