Product details

0.8mm Mezzanine Header — 20 Positions at 0.40mm Pitch

The Hirose BM14B(0.8)-20DP-0.4V(53) is a 20-position header from the BM14 series, designed for board-to-board mezzanine stacking at a mated height of 0.8mm. Gold-plated contacts with a 2.00µin finish handle the mating cycles typical of a production assembly — enough for the connector's service life inside a sealed device.

What the 0.8mm Stack Height and 0.40mm Pitch Mean for Board Layout

At 0.40mm pitch, the routing channels between pads are narrow; a standard 0.2mm trace with 0.2mm clearance fits between adjacent pads, but the board house needs to hold registration within ±0.05mm to avoid solder bridging.

Active Production and RoHS Compliance

The product status is Active.
