Headers, Male Pins Procurement Notes

Verify the specific manufacturer part number against official Molex/AirBorn documentation to ensure compatibility with system requirements. Confirm that the ordering suffix matches the required polarization and guide set specifications. Check for RoHS compliance status if restricted substances are prohibited in the target application environment.

Headers, Male Pins Selection Notes

Select this component when a high-density, right-angle interconnect is required for harsh environments. The dual-row layout maximizes circuit density on the board. Ensure the PCB layout accommodates the 1.91 mm pitch and through-hole tail length. Verify that the PPS material properties align with the thermal management needs of the assembly.

Headers, Male Pins Part Context

This connector belongs to the AirBorn R Series, a line of rectangular connectors designed for demanding applications.
