Board-to-board receptacle for tight-pitch mezzanine stacks
The 2314846-6: It is a bottom- or top-entry design, surface-mount terminated, and ships in tube with pick-and-place features for automated assembly. The tin-plated posts (12 µinch) are the solder tail, where corrosion resistance is less critical. The UL94 V-0 liquid crystal polymer housing holds up in equipment that requires a flame-rated enclosure.
At 2.00 mm pitch, the board footprint is denser than the older 2.54 mm standard — you save about 25% board edge per row for the same circuit count. The dual-row layout with 0.079" row spacing means the overall width across the two rows is about 4.00 mm, plus the body width. The SMT termination with pick-and-place cap means the part is reflow-compatible.
