Procurement Notes

Verify the specific suffix J-L against official AirBorn documentation to confirm terminal type and orientation. Ensure mating parts are selected from the compatible WTB series receptacles or corresponding plugs. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region.

Selection Notes

Select this component when a 70-position, 2-row MIL-DTL-55302 compliant connector is required. It is suitable for applications demanding high reliability and operation up to 125°C. Consider the 2.54 mm pitch and through-hole termination method during PCB layout design to ensure proper footprint compatibility.

Part Context

This part belongs to the AirBorn W Series, designed for mission-critical applications requiring high density and reliability. The series includes various contact counts ranging from 10 to 70 positions. The WTA designation indicates a straight receptacle configuration without mounting ears, distinguishing it from panel-mount variants.

Replacement Considerations

Compatible mating connectors include WTB70SAD9J-B82 and other WTB series receptacles. Verify pin/socket orientation and housing dimensions before substitution to ensure mechanical and electrical compatibility.
