The 0.80mm mated height is the defining mechanical constraint: the opposing board must sit exactly 0.80mm above the host board, with no room for taller components on the facing surfaces. Gold contact finish at 2.00µin thickness is a flash coating — adequate for the limited mating cycles typical of a mezzanine connector that is assembled once and rarely unmated. For applications requiring frequent reconnection, a thicker gold layer would be preferred, but for a fixed board stack this is sufficient. No direct replacement or second-source is listed; the mating half is a Hirose BM10 series header with the same 0.40mm pitch and 0.80mm stack height.","metaTitle":"Hirose BM10NB(0.8)-34DS-0.4V(51) 34-Pos 0.40mm Receptacle","metaDescription":"Hirose BM10 series receptacle, 34 positions, 0.40mm pitch, 0.80mm stack height, gold contacts, SMT.
