60 Circuits at 0.50mm Pitch — Board-to-Board Mezzanine Interconnect
The Hirose DF12B-60DS-0.5V(86) is a 60-position receptacle from the DF12 series, designed for board-to-board mezzanine stacking. The 0.020" (0.50mm) pitch packs 60 circuits into two rows, which means the board footprint is tight — routing a breakout from every pad at this density typically requires at least two inner layers on the PCB. The 0.106" (2.70mm) height above board is the body height; the actual mated stack height depends on the matching header height, with supported stacking heights of 3.5mm, 4mm, and 5mm from this same receptacle part number.
Stack Height Flexibility from One Receptacle
A single DF12B-60DS-0.5V(86) receptacle accommodates three different mated stacking heights — 3.5mm, 4mm, and 5mm — by pairing it with the corresponding DF12 series header of the appropriate height. This means the same receptacle part number can be used across multiple board-spacing designs in a product family, reducing the number of unique line items on the BOM. The 3.5mm stack height is the tightest option, useful for compact handheld or portable equipment where z-height is at a premium.
