Obsolete — sourcing path for this DF12 header
The DF12D(3.5)50DP0.5V80: We source this part per RFQ against the BOM quantity.
3.5 mm stack height, 50 signals, dual-row
The mated stacking height is 3.5 mm — a tight mezzanine gap that suits compact line-card or instrumentation boards.
Board guide and surface-mount fit
A board guide feature is integrated into the housing, which helps align the two PCBs during assembly and reduces shear stress on the solder joints. Surface mount termination means the header reflows with the board — no through-hole solder tails. The 0.50 mm pitch demands a controlled solder-paste stencil and a reflow profile matched to the gold-plated contacts.
