0.40mm pitch, 50 positions — the fine-pitch mezzanine header for tight z-height budgets
The Hirose DF37C-50DP-0.4V(53) is a 50-position header from the DF37 series, designed for board-to-board parallel stacking where vertical space is at a premium. With a 0.016" (0.40mm) pitch and a mated stacking height of 0.98mm, this connector fits into the gap between stacked PCBs in compact consumer electronics — think camera modules, display drivers, or handheld device mainboards.
0.75mm profile — why the height matters for your stack-up
The 0.030" (0.75mm) height above board is the defining dimension for this header. For a 50-position signal interconnect at this pitch, the gold-plated contacts (2.00µin thickness) handle the mating cycles typical of a factory-assembled module that won't be field-serviced.
Sourcing this part for a build
The Tape & Reel packaging (Cut Tape also available) feeds well into a pick-and-place line — the 0.40mm pitch needs a fine-pitch nozzle and vision alignment, but the reel format keeps the feeder stable.
