Its defining feature is the 0.014\" (0.35mm) pitch — one of the tightest in a production mezzanine connector — which, combined with the 2-row layout, packs 54 circuits into a narrow footprint for space-constrained PCBs. The header uses outer shroud contacts that self-align during mating, a necessity when the mated stack height is just 0.8mm and there's no room for a separate alignment frame. The 0.025\" (0.63mm) height above board keeps the profile low, letting the connector sit under components on the opposing board. ## 0.35mm Pitch — What It Means for Board Layout At 0.35mm pitch, trace escape from the inner rows requires micro-vias or very fine-line PCB capability — this is not a connector for a standard 4-layer board with 6/6 mil rules. The 0.8mm mated stack height means the opposing board sits close; the designer must account for component keep-outs on both sides of the stack. The mated pair achieves a 0.8mm stacking height — a common dimension for ultra-thin devices like smartphone main boards to sub-battery boards. The outer shroud contacts on the header engage with the receptacle's inner contacts, providing a self-centering action that compensates for minor board misalignment during assembly.","metaTitle":"Hirose BM23PF0.8-54DP-0.35V(51), 54P 0.35mm Pitch SMT Header","metaDescription":"Hirose BM23 series 54-position header, 0.014\" (0.35mm) pitch, 0.8mm mated stack height.
