Board-to-Board Interconnect for Tight Stack Heights
Sizing the Footprint: Pitch and Position Count
At 0.40mm pitch, the 5033764010 demands a PCB layout with tight trace routing between pads — the narrow spacing limits the current per circuit but keeps the overall connector width under 10 mm for the 40 positions. The 2-row arrangement staggers the contacts, which helps maintain signal integrity by reducing crosstalk between adjacent lines. This is a signal-density play, not a power interconnect; the gold plating and fine pitch suit low-current digital buses and flex-to-board links.
Mounting and Retention Features
The 0.126" (3.20mm) height above board gives a low profile for tight enclosures, but the board guide adds a small footprint extension beyond the contact rows.
