The DF12-20DS-0.5V(86) is a 20-position, dual-row receptacle from Hirose's DF12 series, pitched at 0.50mm. It's designed for board-to-board mezzanine stacking, with gold-plated center strip contacts and a surface-mount termination.
Stack height options and board fit
The height above board is 2.70mm, which sets the clearance under the component. The 0.50mm pitch and 20 positions in two rows mean the footprint is compact — about 5mm wide by 10mm long, typical for this class.
Hirose has marked the DF12-20DS-0.5V(86) as Obsolete. No official successor is listed in the available records, so the replacement path requires checking the DF12 series for a current pin-compatible variant or contacting Hirose directly. If you're populating a BOM, consider whether a current DF12 series receptacle with the same pitch, position count, and stack height range can substitute.
