The DF12B-50DS-0.5V(86): This is a Hirose DF12 series receptacle with center strip contacts, 0.50 mm pitch, 50 positions across two rows.
No official successor is listed on record. For a BOM that already specifies DF12B-50DS-0.5V(86), sourcing is limited to existing distributor stock or the secondary market. We source this per RFQ — confirm the quantity and we will check availability across our supply network.
Mates with the DF12-50DP-0.5V header from the same series. The receptacle sits 2.70 mm above the board, so the header's mated stack height (3.5 mm, 4 mm, or 5 mm) determines the total board-to-board clearance. Surface-mount termination with solder retention pads. The footprint is standard for the DF12 series; the board layout engineer should confirm the pad pattern from the Hirose drawing before committing the PCB.
