WRDDXA122SJTB

Overview

The WRDDXA122SJTB is a rectangular MIL-Spec receptacle from the AirBorn W Series, manufactured by Molex. It features 122 positions arranged in four rows with a 2.54 mm pitch. The connector utilizes crimp termination for 22 AWG wires and includes gold-plated copper alloy female contacts. Designed for PCB mount installation at a straight angle, it employs Polyphenylene Sulfide (PPS) housing. Electrical specifications include a 5 A current rating, 5 GOhms insulation resistance, and operation between -65 C and +125 C.

Feature Summary

• Four-row configuration providing high-density interconnect capability within a compact footprint.
• Crimp termination method ensures secure wire attachment for reliable signal transmission.
• Gold-plated copper alloy contacts offer corrosion resistance and stable conductivity.
• Polyphenylene Sulfide housing provides thermal stability and mechanical durability.

Applications

• Military aerospace avionics systems
• Ruggedized ground-based communication equipment
• High-reliability industrial control panels

Procurement Notes

Verify the specific datasheet revision to confirm RoHS compliance status and exact material certifications before procurement. Ensure mating plug components are selected from the same W Series family to guarantee proper alignment and contact engagement. Confirm that the 22 AWG wire gauge matches your harness specifications for optimal crimp performance.

Selection Notes

Select this part when a 122-position, four-row receptacle is required for board-mounted applications. Verify that the system environment remains within the specified -65 C to +125 C operating range. Ensure the PCB layout accommodates the straight mounting style and the 2.54 mm pin spacing. Confirm compatibility with standard crimping tools for 22 AWG conductors.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series is known for its robust construction and high contact density. The WRDDXA122SJTB specifically addresses needs for multi-row interconnections in space-constrained military and industrial assemblies.

Replacement Considerations

Direct substitutes must match the 122 position count, four-row layout, and 2.54 mm pitch. Verify that any alternative maintains the same crimp termination type and PCB mount orientation. Cross-reference MIL-DTL-55302 equivalents if strict military specification adherence is required.
