What this connector does in the stack
The DF12D(5.0)-50DP-0.5V(81): On a 0.50 mm pitch, the 50 circuits pack into a footprint roughly 12.5 mm long, demanding tight routing discipline on the PCB. Gold contact finish suits repeated mating cycles typical in test or modular assemblies where the board pair is disconnected and reconnected during service.
Obsolete — sourcing the last-time-buy window
Hirose has marked this part as Obsolete, meaning no further production runs are planned. Sourcing is limited to existing distributor or broker inventory; we can search our multi-source network for stock and quote against your BOM quantity on request.
Mechanical fit and footprint check
The connector mounts via Surface Mount technology and includes a Board Guide feature to align the mating receptacle during assembly. Mated stacking height is fixed at 5 mm — confirm your board-to-board gap matches this dimension before committing the design.
