WGA122SOR9SY

Overview

The WGA122SOR9SY is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features 122 positions arranged in three rows with a 2.54 mm pitch. The receptacle utilizes gold-plated copper alloy socket contacts and solder cup termination for PCB mounting. Constructed with a Polyphenylene Sulfide (PPS) housing, it operates between -65°C and +125°C, supports 5 A current, and provides 5 GOhms insulation resistance.

Feature Summary

• Compliant with MIL-DTL-55302 standards for military-grade reliability
• Includes guide set and mounting ears for secure alignment and installation
• Utilizes glass-filled PPS housing for thermal stability

Applications

• Avionics systems requiring high-density interconnects
• Radar and communication equipment chassis
• Military ground vehicle electronic control units

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with mating plugs. Confirm RoHS compliance status and lead times directly with authorized distributors or Molex, as availability varies by region. Ensure ordering specifications match the required right-angle orientation and through-hole termination type.

Selection Notes

Select this component when a 122-position, three-row MIL-DTL-55302 receptacle is required. Verify that the mating plug corresponds to the correct pin configuration and row spacing. Consider the straight versus right-angle mounting options based on board layout constraints and cable routing requirements within the enclosure.

Part Context

This part belongs to the AirBorn W Series, designed for high-reliability applications. It serves as a standard interconnect solution within the MIL-DTL-55302 family, offering robust performance in harsh environments. The series supports various contact counts and orientations to meet diverse system integration needs.

Replacement Considerations

Compatible substitutes include WG80SOR9SY or WG50SOR9SY for lower position counts. For equivalent 122-position configurations, verify cross-reference data with Molex AirBorn engineering to ensure mechanical and electrical compatibility.
