The 0.80 mm pitch on the mating face sets the PCB trace fan-out density; at this pitch the per-contact current is limited more by the pin spacing than by the contact itself. Four mated stack heights are supported — 9 mm, 10 mm, 11 mm, and 12 mm — giving flexibility for mezzanine card spacing in a single board layout. ## Detent lock and surface-mount retention Board guide, pick-and-place pad, and solder retention features are built into the housing — the pick-and-place surface aids automated assembly, and the solder retention anchors the part during reflow. ## Peer comparison: 14-position sibling vs. this 40-position The closest functional sibling is 10159559-410221RLF — same series, same 0.80 mm pitch, same stack heights, same gold plating, but 14 positions (10 signal + 4 power) instead of 40 (30 + 10). The 40-position version is the higher-density choice for boards needing more signal and power circuits in the same footprint.","metaTitle":"10159559-A30221RLF ComboStak 40-Position Receptacle","metaDescription":"Amphenol ICC (FCI) ComboStak receptacle, 40 positions (30+10 power), 0.80mm pitch, SMT, detent lock.
