The contacts carry a gold finish at 8.00 µin thickness, which is the standard plating grade for this series and gives enough corrosion protection and cycle life for production-level mating without driving the cost up to a high-cycle gold flash. Mounting is surface-mount with a solder retention feature. ## Obsolete — Sourced to Order, No Official Replacement Because it is obsolete, the supply window may be limited, so if you have a BOM line that calls this out, it is worth securing the quantity sooner rather than later. ## Mating Half and Board Layout This is the header half of a mezzanine pair. It mates with a DF12 series receptacle that has the same 20-position, dual-row, 0.50 mm pitch layout and a 5 mm stacking height specification. The outer shroud contacts on this header mean the mating receptacle will have a corresponding shroud or housing that fits over the header body. Board layout needs to match the 0.50 mm pitch footprint exactly. The solder retention feature adds extra solder pads that should be included in the footprint.","metaTitle":"Hirose DF12B(5.0)-20DP-0.5V(86) 20-Pin 0.50mm Header","metaDescription":"Hirose DF12B(5.0)-20DP-0.5V(86) 0.50mm pitch, 20-position, dual-row SMT header with 5mm stacking height.
