The 0.98mm mated stack height is a fixed value for this variant; the header counterpart determines the total height, so verify the header part number in the assembly drawing. The 2.00µin gold is a light flash — adequate for the typical 10 to 30 mating cycles in a consumer or handheld device, but if the design calls for frequent reconnects in a test fixture or modular assembly, the DF37NB-20DS-0.4V(75) with 4.00µin gold is the better call.","metaTitle":"Hirose DF37NB-20DS-0.4V(51), 20-Pos 0.40mm Pitch Receptacle","metaDescription":"Hirose DF37NB-20DS-0.4V(51) receptacle, 20 circuits, 0.40mm pitch, 0.98mm mated height.
