It uses center strip contacts in a dual-row layout, surface-mounted with solder retention features to hold the part during reflow. Gold-plated contacts (8.00µin thickness) on the mating interface keep contact resistance stable across repeated mating cycles — typical for signal-level mezzanine interconnects where corrosion resistance matters more than current capacity. ## Stack height options cover 3.5mm to 5mm board spacing This receptacle supports three mated stacking heights: 3.5mm, 4mm, and 5mm — the actual height depends on the mating header selected from the DF12 series. The board-to-board gap is set by the header's post height, not the receptacle alone. The 0.50mm pitch and 2.70mm height above board keep the footprint compact for dense PCB layouts where z-axis clearance is tight. ## Obsolete — sourcing per RFQ only Hirose lists the DF12B-20DS-0.5V(86) as Obsolete. No direct successor is named on record. Buyers with an active BOM line should request a quote for remaining stock or evaluate a pin-compatible alternative from the same DF12 series.","metaTitle":"DF12B-20DS-0.5V(86) Hirose Board-to-Board Receptacle, 20 Pos","metaDescription":"Hirose DF12B-20DS-0.5V(86) 20-position, 0.50mm pitch board-to-board receptacle.
