It carries 50 positions across two rows on a 0.020\" (0.50mm) pitch, with center strip contacts. This plug is designed to mate with the matching receptacle (10156000-051100LF) to create a 3mm mated stack height between parallel PCBs — a common spacing for compact mezzanine card stacks in telecom, networking, and industrial computing assemblies. At this pitch, the escape routing on the PCB needs careful planning, typically using micro-vias or fine-line traces between the pads. The 2.05mm height above board gives the plug a low profile, keeping the z-height budget tight for the overall stack. ## Mating Pair and Stack Height This plug mates specifically with the BergStak 0.50mm Self-Alignment receptacle, order code 10156000-051100LF, which has outer shroud contacts and a 2.65mm height above board. When mated, the pair achieves a 3mm stacking height between the two PCBs — a fixed dimension that cannot be adjusted with different height variants in this series. The self-alignment feature of the BergStak system uses the shroud geometry to guide the plug into the receptacle during mating, reducing the risk of pin stubbing on the fine-pitch contacts. The thin gold layer sits over a nickel underplate; the nickel provides the wear barrier while the gold gives the low-resistance surface. No official cross-reference or second-source beyond the BergStak series itself.","metaTitle":"FCI 10156001-051100LF BergStak Plug, 50 Pos, 0.50mm Pitch","metaDescription":"Amphenol FCI 10156001-051100LF BergStak 0.50mm Self-Alignment plug, 50 positions, 2 rows, 3mm mated stack height.
