0.80mm Pitch, 120-Position Mezzanine Plug — BergStak® 0.80mm Series
Its defining dimensions are the 0.031" (0.80mm) pitch and 0.224" (5.70mm) height above board, which together with the mated stacking heights of 6mm, 10mm, and 14mm determine the exact board-to-board spacing.
Stack Height Selection — Which Mated Pair Hits Your Z-Height Budget
This plug mates with the corresponding BergStak® 0.80mm receptacle to produce one of three published mated stacking heights: 6mm, 10mm, or 14mm. The 0.224" (5.70mm) height above board of this plug is fixed; the variation comes from the receptacle half. For a 6mm stack, pair this plug with a 0.30mm-height receptacle; for 10mm, use a 4.30mm receptacle; for 14mm, an 8.30mm receptacle.
Same Pitch, Same Positions — Three Height Variants in the 120-Position Family
Within the 120-position, 0.80mm-pitch BergStak® plug family, three siblings share every spec except height above board and packaging. The 61083-121402LF sits at 0.185" (4.70mm), the 61083-122400LF matches this part's 0.224" (5.70mm) but ships in tube rather than Tape & Reel, and the 61083-124402LF stands at 0.303" (7.70mm) for taller stack targets. The choice between them is purely a board-to-board Z-height decision — the footprint, pinout, and mating receptacle are identical across all three.
