The housing is natural Liquid Crystal Polymer (LCP) with a phosphor bronze contact spring, gold-plated on the mating surface. ## Solder retention keeps the part planted during reflow This receptacle includes a solder retention feature — metal tabs on the body that reflow into the board pads, holding the connector in place against the shear force of a cable mate or vibration. For a right-angle SMT part, that retention is the difference between a reliable solder joint and a lifted pad on the first cable tug. The 4-position count matches a 4-circuit BOM line. The 0.079\" (2.00mm) pitch is tighter than a 0.100\" header — the footprint is small enough for dense boards but still hand-solderable with a fine tip. Against the 2-position DF59-2S-2V(51) at the same pitch, the decision is purely circuit count: the 4-position version adds two contacts in the same row length increment.","metaTitle":"Hirose DF59-4S-2V(51) Receptacle, 4-Pos, 2.00mm Pitch, 3A","metaDescription":"Hirose DF59-4S-2V(51) 4-position right-angle SMT receptacle, 2.00mm pitch, rated 3A at 230V.
