Procurement Notes

Verify the specific suffix against official datasheets to confirm exact contact orientation and mounting hardware variations. Ensure compatibility with mating receptacles within the same W Series family. Confirm RoHS compliance status via manufacturer certificates prior to integration into regulated assemblies.

Selection Notes

Select this part for applications requiring high pin count density in a compact footprint. The right-angle design facilitates specific PCB layout constraints. Verify that the 5 A rating per contact meets circuit requirements. Ensure the operating environment stays within the specified thermal limits for PPS material stability.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various row counts and contact configurations. The WGA variant specifically denotes a plug with pin contacts and right-angle orientation, distinct from straight or socket variants.

Replacement Considerations

M55302/61B122 is a confirmed cross-reference part number for this component type. Verify mechanical dimensions and contact plating specifications before substitution.
