Procurement Notes

Verify the specific suffix against official Molex / AirBorn documentation to confirm exact mechanical variations such as jackset type or mounting ear configurations. Ensure compatibility with mating plugs within the same W Series family. Confirm RoHS status and lead times directly with authorized distributors, as availability may vary by region.

Selection Notes

Select this part for applications requiring high-density 54-position connections in a right-angle form factor. Ensure the design accommodates the 2.54 mm pitch and through-hole soldering process. Verify that the mating environment supports the specified -65 C to +125 C operating range and that the 5 A current rating per contact meets circuit requirements.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The series offers various position counts and orientations, all adhering to MIL-DTL-55302 standards. The WTB54SOR9J specifically addresses needs for high-pin-count, right-angle board-to-board or cable-to-board interfaces in defense and aerospace sectors.

Replacement Considerations

Cross-reference with other manufacturers holding MIL-DTL-55302 qualifications. Verify dimensional compatibility and pinout alignment before substitution. Contact Molex / AirBorn for confirmed equivalent part numbers or updated revisions.
