The Hirose DF37B-60DP-0.4V(51) is a 60-position header from the DF37 series, designed for board-to-board mezzanine stacking. It uses outer shroud contacts on a 0.40mm pitch, arranged in two rows, and terminates via surface mount.
At 0.40mm pitch, this header demands a precise PCB footprint — the narrow spacing limits routing density on the board and requires careful trace escape. The 60 positions match a 60-conductor BOM line; the two-row layout keeps the connector body compact. Gold contacts with 2.00µin thickness provide adequate corrosion resistance for the typical mating cycle count in a mezzanine application, though the light flash means it is not intended for frequent disconnect-reconnect duty.
Position Count Comparison Within the Series
Against the DF37B-40DP-0.4V(51) which carries 40 positions at the same 0.40mm pitch and 0.75mm board height, the DF37B-60DP-0.4V(51) adds 20 more signal paths in the same footprint width.
