The 0.016\" (0.40mm) pitch and dual-row layout pack 50 circuits into a narrow footprint, making this part a fit for high-density mezzanine interconnects in portable electronics, handheld instruments, and compact embedded systems where board real estate is tight. ## 50 Positions vs 40 and 60 — Which BergStak Count Fits Your BOM This 50-position receptacle sits between the 40-position 10164227-0401A1RLF and the 60-position 10164227-0601A1RLF at the same 0.016\" (0.40mm) pitch and 1.5mm stack height. The decision is purely a circuit-count match: the 50-way version mates with the corresponding BergStak header carrying 50 contacts. There is no difference in footprint width per row — the extra positions extend the connector length along the board edge, so the PCB land pattern scales linearly with position count. This receptacle mates with a BergStak 0.40mm header of the same position count (50). The header must be sourced separately; there is no cross-reference or second-source listed for the mating half. Gold flash on both the receptacle and header contacts is sufficient for the mating cycles in a typical production board stack, but if your application requires frequent reconnection, consider a thicker gold option in the BergStak family.","metaTitle":"10164227-0501A1RLF BergStak 0.40mm Receptacle, 50 Pos","metaDescription":"Amphenol FCI BergStak 0.40mm receptacle, 50 positions, 0.016\" pitch, 1.5mm mated stack height.
