The Hirose BM15FR0.8-24DP-0.35V(53) is a 24-position plug with center strip contacts from the BM15FR series, designed for parallel board-to-board mezzanine stacking at a fixed 0.8mm mated height. The 0.014" (0.35mm) pitch packs 24 signal contacts into a compact dual-row footprint, suited for dense PCB layouts in portable electronics, handheld devices, and camera modules where board z-height is tight. Gold-plated contacts with a 2.00µin finish handle the mating cycles typical of a factory-assembled permanent connection — not a field-service disconnect.
What the 0.8mm Stack Height Means for Board Spacing
The 0.8mm mated stacking height is the defining dimension for this connector — it sets the gap between two parallel PCBs when the plug mates with its matching receptacle. The 0.024" (0.61mm) height above board on the plug side tells the layout engineer how much the component protrudes from the PCB surface before mating.
For the pick-and-place line, the tape-and-reel packaging feeds the part directly into the nozzle — no tray handling required.
The BM15FR series offers the same 0.35mm pitch, 0.8mm stack height, and gold plating across multiple position counts. The 24-position BM15FR0.8-24DP-0.35V(53) sits between the 22-position BM15FR0.8-22DP-0.35V(53) and the 30-position BM15FR0.8-30DP-0.35V(53). All share identical board footprint dimensions except for the length of the contact row — so swapping position counts requires a layout change to the pad pattern, not a re-spin of the stack height or keep-out zone.
