Product details

Board-to-Board Mezzanine Fit

The Hirose DF40TC(3.5)-20DS-0.4V(58) is a 20-position receptacle from the DF40T series, designed for parallel board stacking at a 3.5mm mated stack height. The 0.40mm pitch means the board footprint is dense — expect fine-trace routing and micro-via or HDI layer transitions to escape the outer rows. The 3.5mm stack height is the dimension that decides enclosure fit; confirm the gap between the two PCBs before specifying. Solder retention features and a pick-and-place vacuum area support automated assembly on a standard SMT line.

RoHS compliant per the listing. No official second-source cross-reference exists within the DF40T family for this exact stack height and position count.
