Board-to-Board Stacking Header for Tight Pitch Designs
The 10164228-0341A1RLF: The 0.016" (0.40mm) pitch packs 34 circuits into a dual-row SMT footprint, making it a fit for compact handheld devices, portable instrumentation, and dense mezzanine interconnects. 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.
