Procurement Notes

Verify the specific suffix 'SYL' or 'SY' against official Molex documentation to confirm exact contact orientation and hardware configuration. Confirm RoHS compliance status directly with the manufacturer as datasheet details may vary. Ensure mating part compatibility within the W Series before procurement.

Selection Notes

Select this model for applications requiring high-density 40-position interconnects in constrained spaces. The straight plug design suits direct PCB mounting where panel access is limited. Verify that the 5 A current rating meets circuit requirements and that the PPS material withstands the operational thermal environment.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding industrial and defense applications. The series offers various contact counts and termination options, providing standardized interfaces for reliable connectivity in aerospace and military sectors.

Replacement Considerations

Cross-reference with M55302/63B40X equivalents. Verify mechanical dimensions and contact gender compatibility with existing receptacles before substitution.
