The 0.020\" (0.50mm) pitch packs 50 circuits into a compact dual-row footprint, making it a fit for dense PCB layouts where signal routing space is tight. Gold-plated contacts on the mating interface keep contact resistance low across repeated mate/unmate cycles — typical for modular mezzanine cards in telecom or test equipment that see field service. This shroud protects the contacts during handling and prevents bent pins on first mate. ## 5mm Stack Height — Fixed, Not Adjustable The mated stacking height is 5mm, set by the header's body height above the board at 0.169\" (4.30mm) plus the mating receptacle's own height. This is a fixed parameter — the DF12 series offers multiple stack-height variants (3mm, 4mm, 5mm, 8mm), and the (5.0) in the order code locks this part to the 5mm version. If your board-to-board gap is different, this header will not align with the mating receptacle. The 0.50mm pitch gives enough room between contacts for signal routing on inner layers without forcing microvia fan-out, but the trace escape under the header needs careful planning — two rows at 0.50mm pitch means the inner row pads are staggered relative to the outer row. ## Obsolete — Sourcing Through Surplus Channel This means the part is no longer in factory production, and new stock is not being manufactured. Sourcing is limited to surplus inventory held by independent distributors or broker channels. ## What Replaces DF12(5.0)-50DP-0.5V? Hirose does not list a direct replacement for this order code. Within the DF12 series, the closest pin-compatible alternative would be another 50-position header with the same 0.50mm pitch and 5mm mated stacking height — but the exact order code suffix (DP for header, 0.5V for pitch, (5.0) for stack height) must match the mating receptacle's own stack-height variant. Without an official cross-reference from Hirose, any substitution requires checking the mating half's part number and verifying the board footprint matches. The DF12 series includes headers with different stack heights (3mm, 4mm, 8mm) and different position counts (10 to 60), so a 50-position header at a different stack height will not mate correctly with the same receptacle.","metaTitle":"Hirose DF12(5.0)-50DP-0.5V Header, 50 Pos, 0.5mm Pitch","metaDescription":"Hirose DF12(5.0)-50DP-0.5V 50-position header, 0.5mm pitch, 5mm stacking height.
