Tin or flash-gold contacts would fret and oxidise under the same duty; this one is specced for it. ## 40 positions — mid-density in the FH family The same series includes a 60-position variant (5084618-2) and a 120-position variant (5353999-5), all sharing the same 0.80 mm pitch and 30.0 µin gold plating. The choice between them is purely a circuit-count decision — the footprint pitch and stack height are identical, so a board laid out for 40 positions can scale to 60 or 120 only if the connector footprint length is adjusted for the extra positions. ## SMT mounting, Tape & Reel — built for the pick-and-place line Surface-mount termination and Tape & Reel packaging mean this connector is set for automated assembly. The board guide feature helps the pick-and-place nozzle centre the part on the footprint pads, and the shroud protects the contacts during reflow.","metaTitle":"TE 5353999-1 Free Height (FH) Receptacle, 40 Pos","metaDescription":"TE Connectivity 5353999-1 Free Height (FH) receptacle, 40 positions, 0.80mm pitch, 5mm stack height.
