The 1-640387-8: The friction lock provides a positive retention between header and receptacle without a secondary latch — enough for moderate vibration in general-purpose and industrial equipment, but not for high-shock automotive environments.
Confirm that your PCB edge clearance and mating receptacle width accommodate this. For higher current, consider the same series with gold plating or a larger pitch system.
This header mates with MTA-156 receptacle housings that accept crimp or IDC terminals. Pin 1 is typically marked by a chamfer or notch on the housing; watch it every press. The single-wall shrouding offers some protection against bent pins during handling, but not full enclosure — take care during board handling and mating.
Because this is an active, standard-series part, lead times are typically short, but we confirm availability per your quantity before committing.
