Headers, Male Pins Procurement Notes

Verify the specific manufacturer source, as AirBorn operates under Molex. Confirm that the part number matches the exact suffix requirements for your application, as variations may exist within the W Series. Check for RoHS compliance status if required by your project specifications. Ensure that the right-angle orientation aligns with your mechanical layout before ordering. Validate availability through authorized distributors to avoid counterfeit components.

Headers, Male Pins Selection Notes

Select this component when a 44-position male header is required for MIL-DTL-55302 applications. The 2.54 mm pitch suits standard density PCB layouts. Consider the right-angle form factor for space-constrained designs where vertical clearance is limited. Verify that the 5 A current rating meets the circuit load requirements. Ensure compatibility with corresponding female receptacles in the same series for proper mating.

Headers, Male Pins Part Context

This connector belongs to the AirBorn W Series, a line of rectangular connectors known for durability in harsh environments. The M55302 designation indicates adherence to the MIL-DTL-55302 specification, which defines performance standards for military-grade interconnects. As a product of Molex, it benefits from established manufacturing quality controls while maintaining specialized defense industry certifications.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 44-position count, male pin configuration, 2.54 mm pitch, and right-angle orientation. Cross-reference with other manufacturers offering MIL-DTL-55302 compliant headers. Verify that alternative parts support the same -65 C to +125 C temperature range and 5 A current rating. Ensure housing material and contact plating specifications are equivalent to maintain interface integrity.
