0.80 mm pitch, 14 positions: mixed power and signal layout
The 10159558-410421RLF: This is a ComboStak vertical header from Amphenol ICC (FCI) with a 0.80 mm pitch and 14 total positions — 10 signal contacts and 4 power contacts in a 2-row arrangement. The mixed layout lets a single connector carry both low-current signal lines and higher-current power feeds, reducing the number of separate connectors on the board edge. A detent lock provides audible positive retention once mated.
Stack height range: 8 mm to 20 mm
The mated stacking height is selectable from 8 mm, 12 mm, 16 mm, or 20 mm, depending on the mating receptacle height variant. This range covers typical board-to-board or board-to-cable clearances in compact enclosures where z-height is tight. Compared to the sibling 10159558-A30221RLF, which offers 40 positions (30 signal + 10 power) and stacking heights of 6 mm, 10 mm, 14 mm, and 18 mm, this 14-position version is a lower-density option for designs that need fewer circuits but the same pitch and series compatibility.
