It mates to a stacking height of 3mm — the gap between boards is fixed by the connector body, not adjustable. The outer shroud contacts and solder retention features help keep the connector seated during reflow and in service, but the 0.50mm pitch leaves little room for misalignment — the board-to-board float is tight. ## Obsolete — plan for an alternative Hirose has marked this part as Obsolete. For a new design, look at the active DF12 series variants — the pitch and stacking height are the same, but confirm the position count and contact finish. ## Gold finish and surface-mount termination The surface-mount tails suit a standard reflow profile.","metaTitle":"DF12B(3.0)-40DP-0.5V(86) Hirose DF12 Board-to-Board","metaDescription":"Hirose DF12B(3.0)-40DP-0.5V(86) header, 40 positions, 0.50mm pitch, 3mm stacking height, gold contacts.
