0.35mm pitch, 58 positions, 0.6mm stack — the BM28 high-density mezzanine receptacle
The Hirose BM28B0.6-58DS/2-0.35V(53) is a 58-position receptacle with center strip contacts from the BM28 series, designed for board-to-board mezzanine stacking at a mated height of 0.6mm. The 0.014" (0.35mm) pitch packs 58 circuits into a dual-row layout that fits ultra-compact handheld and portable device PCBs where z-height is under 1mm.
Active lifecycle and RoHS compliance — no sourcing surprises
The BM28B0.6-58DS/2-0.35V(53) carries an active product status with RoHS compliance confirmed.
Board layout fit — what the 0.35mm pitch and 0.6mm stack mean
The 0.024" (0.61mm) height above board and 0.6mm mated stacking height set the z-axis budget: the mating header must sit on the opposing board at a combined stack that clears any components underneath. Solder retention features add mechanical hold during reflow and resist the shear force from cable or board movement in the final assembly.
