WGA122SACJ

Overview

The WGA122SACJ 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. Designed as a PCB mount receptacle, it utilizes solder cup termination for 22 AWG wires. The housing is constructed from Polyphenylene Sulfide (PPS), and contacts are gold-plated copper alloy sockets rated for 5 A current. It operates between -65 C and +125 C with an insulation resistance of 5 GOhms.

Feature Summary

• High-density interconnect capability provided by a 122-position, three-row configuration within a compact footprint.
• Robust environmental resilience ensured by PPS housing material and wide operational temperature range.
• Secure electrical connection achieved through gold-plated copper alloy socket contacts with solder cup termination.

Applications

• Military avionics control systems
• Aerospace communication equipment
• Ruggedized electronic instrumentation

Procurement Notes

Verify the specific revision level and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the solder cup termination method aligns with your assembly process capabilities. Ensure the straight mounting style fits the mechanical constraints of the target PCB layout. Cross-reference the MIL-DTL-55302 requirements against the component datasheet to validate performance standards for the intended application environment.

Selection Notes

Select this component when high pin count density is required in a rectangular form factor. The three-row design maximizes connectivity within limited board space compared to two-row alternatives. Verify that the 2.54 mm pitch matches existing trace routing patterns. Consider the 5 A current rating per contact to ensure adequate power handling for the circuit loads without exceeding thermal limits during operation.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding military and aerospace applications. The series emphasizes reliability and durability in harsh environments. The WGA122SACJ specifically represents a high-density receptacle variant, offering extensive I/O options for complex electronic systems requiring robust signal integrity and mechanical stability.
