DF37C-16DP-0.4V(75) from Hirose Electric Co Ltd is a fine-pitch rectangular board-to-board connector header designed for compact electronic assemblies where height, density, and connection reliability are critical. As part of the DF37 series, this 16-position, 0.40 mm pitch surface-mount connector is well suited for portable devices, industrial control modules, medical electronics, and other space-constrained embedded systems that require mezzanine board stacking. Engineers typically select this part when designing low-profile interconnect architectures that need consistent signal transfer in tightly packed PCB layouts. The gold contact finish and tape-and-reel packaging also support automated assembly and dependable mating performance in volume production. Based on the provided specifications, the product status is Active, which is favorable for ongoing procurement planning; however, lifecycle verification should still be confirmed through Hirose or current authorized channel data. RoHS compliance information is not explicitly provided in the input specifications, so compliance status should be treated as information not available pending manufacturer documentation or an official datasheet review.
