The 0.50mm pitch and dual-row layout pack 40 circuits into a compact footprint, while the three available mated stacking heights — 6mm, 6.5mm, and 8mm — let you tune the board gap without changing the receptacle. ## Stack Height Selection and Board Layout Fit The mated stacking height range of 6mm, 6.5mm, and 8mm gives the board designer three gap options from a single receptacle part number — the mating header determines the final stack. The 0.50mm pitch keeps the per-row routing density high, which matters when signal traces must escape between pads on inner layers. ## Mounting and Retention for SMT Assembly The board guide also acts as a polarization aid — the mating header must align to the receptacle's guide slots, which prevents off-angle insertion that could bend contacts. Tape & Reel packaging supports automated pick-and-place for volume production.","metaTitle":"Hirose DF17(4.0)-40DS-0.5V(57) Receptacle, 40 Pos","metaDescription":"Hirose DF17 series receptacle, 40 positions, 0.50mm pitch, dual-row, gold contacts, SMT.
