60-Position 0.50mm Pitch Mezzanine Receptacle — Now Obsolete
The Hirose DF12A-60DS-0.5V(80) is a 60-position receptacle with center strip contacts from the DF12 series, designed for board-to-board mezzanine stacking. At 0.020" (0.50mm) pitch, it packs 60 circuits into a compact 2-row layout — the kind of density that demands careful footprint registration and a clean solder paste stencil. The gold-plated contacts and built-in board guide help keep alignment true during mating, which matters when the mated stack height can be 3.5mm, 4mm, or 5mm depending on the plug header height you pair it with.
Stack Height Flexibility — One Receptacle, Three Gaps
A single DF12A-60DS-0.5V(80) receptacle supports mated stacking heights of 3.5mm, 4mm, and 5mm by pairing it with the corresponding DF12 plug header height. That means the board-to-board gap is set by the plug, not the receptacle — useful when you need to keep the receptacle BOM line constant across multiple board stack-ups in the same assembly. The 0.106" (2.70mm) height above board gives a low profile on the receptacle side, leaving the z-height budget to the plug side.
Board Guide and Contact Finish
The integrated board guide helps self-align the connector during mating — a practical feature at 0.50mm pitch where even a small misalignment can damage contacts or cause intermittent opens. Surface-mount termination keeps the assembly compatible with standard reflow processes.
