Headers, Male Pins Procurement Notes

Verify the specific termination plating configuration against project requirements, as datasheets may list variations such as tin/lead or gold depending on the exact suffix. Confirm RoHS compliance status prior to procurement, as some variants in this series are non-compliant. Ensure the straight mounting style aligns with the mechanical layout constraints of the target printed circuit board assembly.

Headers, Male Pins Selection Notes

Select this component when a low-profile, multi-row interconnect solution is required for space-constrained military applications. The 1.91 mm pitch allows for moderate circuit density while maintaining robust mechanical stability. Consider the straight orientation for direct board insertion and verify that the 3 A current rating meets the thermal management needs of the specific signal lines.

Headers, Male Pins Part Context
