Mated stack height is 0.045\" (1.14 mm) above the board — this sets the z-height between parallel PCBs for mezzanine card spacing. Gold-plated contacts (1.97 µin) resist fretting corrosion over repeated mating cycles, suited for field-serviceable assemblies where reconnect duty is moderate. Pick-and-place compatible with solder retention features for automated assembly and reflow stability. ## Mating receptacle and stack height Mates with the DF40T series receptacle. The 0.045\" (1.14 mm) height above board defines the mated stack height — confirm the opposite board's clearance before layout.","metaTitle":"DF40TC-40DP-0.4V(51) 0.40mm Pitch Header, 40 Pos","metaDescription":"Hirose DF40T series header, 40 positions, 0.40mm pitch, 1.14mm stack height.
