Headers, Male Pins Procurement Notes

Verify the specific suffix '5504BN' against official Molex documentation to confirm environmental sealing or special coating requirements. Confirm RoHS status and lead times directly with the manufacturer, as this part may be subject to factory special order constraints. Ensure compatibility with mating receptacles within the same R Series family before procurement.

Headers, Male Pins Selection Notes

Select this component when a right-angle, board-mount solution with mounting ears is required for 40-position interconnects. The 1.91 mm pitch dictates footprint constraints on the PCB layout. Verify that the through-hole termination method aligns with the assembly process capabilities and that the PPS material properties meet the thermal profile of the application.

Headers, Male Pins Part Context

This connector belongs to the AirBorn R Series, designed for rectangular MIL-Spec applications. It is part of the broader Molex portfolio, leveraging AirBorn's heritage in rugged connectivity. The series is characterized by high-density pin configurations and robust mechanical retention suitable for vibration-prone environments.

Headers, Male Pins Replacement Considerations

Cross-reference with standard MIL-DTL-55302 equivalents. Check for compatible mating parts within the R Series lineup. Verify dimensional tolerances and contact geometry against existing designs to ensure interchangeability without PCB rework.
