Board-to-Board Mezzanine Receptacle, 11 Positions, 1.00mm Pitch
It uses a 0.039" (1.00mm) pitch dual-row layout with outer shroud contacts, and mates to a matching DF9 series header to achieve a 4.3mm mated stack height. The tin-plated contacts and surface-mount termination suit it for high-density internal board interconnects where the stack height is fixed by the enclosure design.
Position Count and Series Fit
At 11 positions, this is an odd-count member of the DF9A family. The same 0.130" (3.30mm) height above board and 1.00mm pitch carry across the series, so the footprint and stack height are consistent whether you need 9 circuits (DF9A-9S-1V(22)), 31 circuits (DF9A-31S-1V(22)), or 41 circuits (DF9A-41S-1V(22)). The 11-position variant fills the gap between the 9- and 31-position options — useful when the signal count lands on an odd number and you want to avoid wasting a row.
