It sits in the 2291316 base series, which covers fine-pitch SMT receptacles for parallel PCB interconnect. The 0.024" (0.60mm) pitch and dual-row layout pack 74 circuits into a compact footprint — the tight pitch demands a controlled board layout with fine-line traces and matching via keep-outs. Surface-mount termination with board guide and pick-and-place features targets automated assembly lines, not hand-solder rework.
74 circuits at 0.60 mm pitch — footprint fit is everything
The 0.024" (0.60mm) pitch is the tightest selection parameter on this part. It drives the board footprint — standard 0.062" FR4 with 0.008" traces and 0.010" spaces will route 74 signals through two rows, but the via fanout under the receptacle needs a controlled impedance stack-up if signals run above a few hundred MHz. The 0.537" (13.65mm) height above board sets the mezzanine gap between the two PCBs; the mating header must match that stack height exactly or the contacts won't engage fully. Gold contact finish is standard for this pitch class — tin would gall after a few mating cycles at 0.60 mm.
SMT assembly — pick-and-place ready
The pick-and-place feature means the part is vacuum-pickup compatible for automated placement — no hand-soldering this pitch. Tape & Reel packaging feeds directly into a standard SMT line; the reel quantity should match the board run volume to avoid mid-run reel changes.
