0.40 mm pitch, 34 positions, 0.9 mm stack — the footprint fit
The DF30FB-34DS-0.4V(82): This is a 34-position, 2-row receptacle from the Hirose DF30 series, pitched at 0.016" (0.40mm) and designed for a 0.9mm mated stack height. The outer shroud contacts and gold finish (2.00µin) suit it for dense, low-profile board-to-board interconnects where signal integrity matters more than current — the fine pitch limits per-contact current, but the gold plating handles repeated mating cycles cleanly.
Solder retention and surface-mount assembly
Surface-mount termination and Tape & Reel packaging mean it feeds into standard pick-and-place lines without manual handling.
Obsolete — sourcing path for BOM continuity
Hirose has marked the DF30FB-34DS-0.4V(82) as Obsolete. No official successor is listed in the evidence, so the closest pin-compatible alternative would need to match the 0.40mm pitch, 34 positions, 2-row layout, and 0.9mm stack height — a direct cross-reference is not on record.
