Product details

Ultra-fine pitch for tight board stacking

The BM28B0.6-20DS/2-0.35V(53): This is a 0.35mm pitch, 20-position, 2-row receptacle from the Hirose BM28 series — the tightest pitch in the family, built for mezzanine stacking at just 0.6mm mated height. The gold-plated contacts (1.97µin thickness) handle repeated mating in thin-profile designs like wearables or compact handhelds where every tenth-mm of z-height matters.

With a 0.6mm mated stack height and 0.61mm height above board, this receptacle sits nearly flush with the PCB surface. The 0.35mm pitch demands a precise footprint — the pad layout and solder paste stencil aperture directly control the coplanarity after reflow.

Frequently asked questions

What is the mating header for BM28B0.6-20DS/2-0.35V(53)?

The mating half is a BM28 series header with matching 0.35mm pitch and 0.6mm stack height. The exact header part number depends on position count and orientation; check the BM28 series datasheet for the specific header that pairs with this 20-position receptacle.

What is the closest pin-compatible alternative to BM28B0.6-20DS/2-0.35V(53)?

No direct pin-compatible substitute is listed for this exact 0.35mm pitch, 20-position, 0.6mm stack height receptacle. Any alternative would need to match the pitch, position count, row count, and stack height exactly — a different series would require a board layout change.
