Outer shroud contacts protect the signal pins during mating and guide alignment with the matching receptacle. ## Stack Height Options and Board Layout Fit This header supports mated stacking heights of 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm, giving the board stack-up engineer a range of z-height choices without changing the PCB footprint. The 0.40mm pitch means trace routing between pads requires controlled impedance design — the narrow pitch limits per-circuit current capacity, so this part is best suited for signal-level duty rather than power distribution. The SMT termination suits automated pick-and-place assembly with Tape & Reel packaging. ROHS3 compliance covers EU regulatory requirements for the bill of materials. ## Position Count Comparison Across the Series The 34-position 10164228-0341A1RLF sits between the 40-position 10164228-0401A1RLF and the 70-position 10164228-0701A1RLF in the same BergStak 0.40mm series, all sharing the same 0.016\" (0.40mm) pitch, 0.045\" (1.14mm) height above board, dual-row layout, and gold flash contacts. No other functional difference separates them.","metaTitle":"Amphenol FCI 10164228-0341A1RLF BergStak 0.40mm Header","metaDescription":"Amphenol FCI BergStak 0.40mm header, 34 positions, 0.40mm pitch, gold flash contacts, SMT, ROHS3.
