Headers, Male Pins Procurement Notes

Verify the specific contact material variant, as datasheets may list both copper and copper alloy options for this series. Confirm RoHS compliance status directly with the manufacturer, as historical production runs vary. Ensure the ordering suffix matches the required termination style and mounting configuration. Cross-reference the MIL-DTL-55302 drawing number to guarantee exact dimensional compatibility with existing chassis designs.

Headers, Male Pins Selection Notes

Select this model for applications demanding right-angle PCB connections with moderate pin counts. The 2.54 mm pitch allows for standard trace spacing while maintaining high density. Verify that the 5 A current rating meets the circuit requirements. Consider the operating temperature range when selecting materials for adjacent components to ensure thermal compatibility during peak load conditions.
