WGA122PR9SYFM

Overview

The WGA122PR9SYFM 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 component utilizes gold-plated beryllium copper pin contacts and a polyphenylene sulfide (PPS) housing. Designed for through-hole mounting at a right angle, it supports a current rating of 5 A and operates within a temperature range of -65 °C to +125 °C.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 standards
• Right-angle board-to-board connectivity via through-hole termination
• High-density signal routing with 122 contact positions

Applications

• Avionics systems requiring high-reliability interconnects
• Radar and electronic warfare equipment
• Military communication subsystems

Procurement Notes

Verify the specific suffix FM against official Molex/AirBorn documentation to confirm tail length and guide pin configurations. Ensure compatibility with mating receptacles such as the WGR series. Confirm RoHS compliance status directly with the manufacturer, as military variants may have specific regulatory requirements distinct from commercial equivalents.

Selection Notes

Select this part for applications demanding right-angle PCB integration with high pin counts. The 2.54 mm pitch ensures standard spacing compatibility. Verify that the 5 A current rating per contact meets system load requirements. Consider the mechanical stability provided by the mounting flange and guide pins for vibration-prone environments typical in defense sectors.

Part Context

This component belongs to the AirBorn W Series, a line of high-performance rectangular connectors designed for harsh environments. The series is characterized by its rugged plastic housing and reliable metal contacts, widely used in aerospace and defense industries where space constraints and signal integrity are critical.

Replacement Considerations

Compatible mating parts include WGR-series receptacles. Verify pin-to-pin alignment and housing dimensions before substitution. Cross-reference with MIL-DTL-55302 specifications to ensure equivalent performance characteristics in critical deployments.
