Procurement Notes

Verify the specific suffix '9' against official Molex/AirBorn documentation to confirm polarization or guide set configuration. Ensure compatibility with mating plugs such as the WTB120PR9SY series. Confirm RoHS compliance status via the manufacturer's certificate before integration into regulated assemblies.

Selection Notes

Select this part for high-density interconnects requiring MIL-DTL-55302 certification. The straight through-hole design suits vertical PCB mounting. Verify that the 120-position count matches the circuit requirements and that the 2.54 mm pitch aligns with the target board layout constraints.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors engineered for demanding environments. The series offers various position counts and termination styles while maintaining consistent electrical performance standards defined by the governing military specification.

Replacement Considerations

The part number alias M55302/60-C120Y-3 indicates potential cross-reference availability under the original MIL-DTL-55302 designation. Verify exact mechanical and electrical equivalence with any alternative source.
