WGA122SAD9J

Overview

The WGA122SAD9J 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 a Polyphenylene Sulfide (PPS) shell. Designed for PCB mount installation, it employs solder cup termination. The component supports a current rating of 5 A, operates between -65 C and +125 C, and offers an insulation resistance of 5 GOhms.

Feature Summary

• High-density interconnect capability with 122 positions in a compact three-row configuration
• Robust construction using Polyphenylene Sulfide housing and gold-plated copper alloy contacts
• Compliance with MIL-DTL-55302 standards for military-grade reliability

Applications

• Military avionics systems requiring high pin count interconnects
• Radar and electronic warfare equipment interfaces
• Ground-based communication infrastructure

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact termination geometry and mounting variations. Ensure compatibility with mating plugs regarding keying options and contact arrangements. Confirm RoHS status and environmental certifications required for the target deployment environment before finalizing procurement.

Selection Notes

Select this part for applications demanding high signal density within strict form factors. The 2.54 mm pitch allows for standard board layouts while maintaining MIL-spec durability. Evaluate thermal management needs given the 125 C maximum operating temperature and verify that the solder cup termination method aligns with the assembly process capabilities.
