0.35mm Pitch, 18-Position Mezzanine Receptacle
The Hirose BM23FR0.8-18DS-0.35V(895) is an 18-position receptacle with center strip contacts from the BM23 series, designed for board-to-board stacking at a mated height of 0.8mm.
18 Positions vs 10 — Same Footprint, Different Circuit Count
The 18-position BM23FR0.8-18DS-0.35V(895) shares the same 0.35mm pitch, 0.8mm mated height, and gold plating as the 10-position BM23FR0.8-10DS-0.35V(51). The difference is the circuit count — 18 positions against 10 — which changes the board footprint length. If your BOM calls for 18 signal lines, this is the direct match; the 10-position sibling won't cover the extra lanes without a second connector. The mating header is the BM23FR0.8-18DP-0.35V(895), same pitch and position count, outer shroud contacts — confirm both halves before committing the layout.
Solder Retention Pads Hold the Receptacle Through Reflow
The Solder Retention feature adds extra hold-down pads to the SMT footprint, keeping the receptacle aligned during reflow and resisting shear forces from cable strain or board flex after assembly. The Tape & Reel packaging (Cut Tape option available) feeds directly into a pick-and-place line; no hand-loading step.
