The Hirose DF12-40DS-0.5V(80) is a 40-position receptacle from the DF12 series of board-to-board mezzanine connectors. The receptacle carries gold-plated contacts and surface-mount terminations. The 2.70 mm height above board and mated stacking heights of 3.5 mm, 4 mm, and 5 mm give the board layout engineer flexibility in z-axis spacing between stacked PCBs. ## Key Specs for the Board Fit The 40 positions in 2 rows give 20 contacts per row, a standard count for a 40-circuit mezzanine bus. The 2.70 mm height above board is the receptacle's own profile; the total mated stack height depends on the header chosen. The DF12 series supports multiple header heights to achieve the three listed mated stacking heights — 3.5 mm, 4 mm, and 5 mm — so the same receptacle can pair with different headers to fit the board spacing budget.","metaTitle":"Hirose DF12-40DS-0.5V(80) 40-Position 0.50mm Receptacle","metaDescription":"Hirose DF12-40DS-0.5V(80) 40-position 0.50mm pitch receptacle, center strip contacts, 2.70mm height, 3.5-5mm stack.
