Procurement Notes

Verify the specific suffix against official Molex documentation to confirm exact mating compatibility and environmental sealing requirements. Confirm RoHS status and lead times directly with authorized distributors, as availability varies. Ensure the ordering part number matches the required pin configuration and mounting style precisely.

Selection Notes

Select this model for applications requiring high-density interconnects in harsh environments. The right-angle design facilitates compact board layouts. Verify that the 104-position count and 3-row arrangement fit the target PCB footprint. Ensure the 5 A current rating meets the circuit load requirements.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding industrial and military use. The series is characterized by its compliance with MIL-DTL-55302 standards, offering robust performance in extreme conditions. The WG104 variant specifically provides a high pin count solution for complex signal routing.

Replacement Considerations

Compatible substitutes may include other MIL-DTL-55302 compliant plugs with identical 104-position, 3-row, right-angle configurations. Cross-reference dimensions and contact plating before substitution.
