Headers, Male Pins Procurement Notes

Verify the specific suffix '-27' against official Molex/AirBorn documentation to confirm exact plating thickness or environmental rating variations. Ensure compatibility with mating receptacles such as the WTB120SAD11SY-1 series. Confirm RoHS compliance status directly with the manufacturer, as legacy military parts may have specific regulatory exemptions. Request certified test reports for critical aerospace or defense procurement channels.

Headers, Male Pins Selection Notes

Select this model when a 120-position right-angle male connector is required for MIL-DTL-55302 environments. Compare against straight variants if panel mounting is preferred over board mounting. Verify that the 2.54 mm pitch aligns with existing PCB trace spacing. Ensure the PPS housing material meets thermal requirements for the intended operating environment.
