WRDDXA122SSY

Overview

The WRDDXA122SSY is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features a free-hanging panel mount receptacle configuration with 122 positions arranged in four rows. The unit utilizes crimp termination for 22 AWG wires and gold-plated copper alloy sockets. Constructed with Polyphenylene Sulfide (PPS) housing, it operates between -65°C and +125°C with a 5A current rating and 5 GOhm insulation resistance.

Feature Summary

• MIL-DTL-55302 qualified military-grade construction
• Free-hanging panel mount receptacle design
• Gold-plated contacts for reliable signal transmission

Applications

• Military avionics systems
• Ruggedized industrial control panels
• Defense communication equipment

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact contact orientation and plating thickness. Ensure compatibility with mating plugs within the same W-Series family. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component for applications requiring high-density I/O in constrained panel spaces. The 2.54mm pitch supports standard wiring harnesses. Evaluate thermal requirements against the specified operating range. Ensure mechanical clearance accommodates the free-hanging form factor during installation.

Part Context

This part belongs to the AirBorn W Series, designed for harsh environments. It complements other W-Series components like WRDDXA122SJTB, differing primarily in mounting style and termination method. The series provides standardized interfaces for critical defense and aerospace interconnect needs.

Replacement Considerations

Direct substitutes include WRDDXA122SJTB for PCB mount variants or WRDDXA122SJTL-A53 for cable mount versions. Verify pinout consistency before swapping. Cross-reference MIL-DTL-55302 specifications to ensure equivalent environmental sealing and durability ratings.
