Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'JTB' against the official Molex/AirBorn datasheet to confirm tail length, jackset type, and mounting ear configuration. Ensure compatibility with mating plug series. Check RoHS compliance status directly on the manufacturer's certificate. Confirm availability as distribution status may vary by region.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 70-position dual-row connector is required for MIL-DTL-55302 applications. Verify that the 2.54 mm pitch fits the PCB layout constraints. Ensure the 5 A current rating per contact meets the circuit load requirements. Confirm the operating temperature range of -65 C to +125 C aligns with the environmental conditions of the target application.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. As a Molex company, AirBorn provides specialized interconnect solutions for OEMs globally. The W Series is distinct from the iPowerAmp family, focusing on standard density MIL-spec performance rather than high-current single-row configurations.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 70-position count, 2-row configuration, and MIL-DTL-55302 compliance. Verify identical pinout and mechanical dimensions before substitution. Generic equivalents may lack the specific gold plating or PPS material properties required for certified aerospace use.
