Product details

0.40mm pitch mezzanine receptacle, 10 positions, 0.80mm stack

The Hirose BM20B(0.8)-10DS-0.4V(53) is a 10-position receptacle with center strip contacts from the BM20 series, designed for board-to-board mezzanine stacking at a 0.80mm mated height. The 0.016" (0.40mm) pitch drives the PCB footprint — tight enough for dense routing but requires a matching BM20 series header on the opposite board. Gold contact finish handles the mating cycles typical of internal mezzanine connections in portable electronics and compact modules.

SMT with solder retention — holds position through reflow

Surface mount termination with solder retention features means the connector stays put during reflow without secondary clips. Two rows of contacts at 0.40mm pitch give 10 total positions — confirm your circuit count matches before committing the BOM line.

Frequently asked questions

What is the mated stacking height of BM20B(0.8)-10DS-0.4V(53)?

The mated stacking height is 0.8mm, matching the 0.031" (0.80mm) height above board spec. This defines the z-axis clearance between the two PCBs in a mezzanine stack.

Is BM20B(0.8)-10DS-0.4V(53) compatible with standard BM20 series plugs?

Yes, this receptacle mates with the matching BM20 series header (outer shroud contacts), such as the BM20B(0.8)-10DP-0.4V(53). Both share the same 0.40mm pitch and 10-position count — confirm the header's mated height matches your stack-up.

Where can I buy BM20B(0.8)-10DS-0.4V(53) and what is the lead time?
