The 0.157" (4.00 mm) pitch gives you enough room between contacts to route traces without crowding, and the 125 V rating means it handles typical board-level power and signal without creepage concerns. Gold-plated contacts on copper alloy keep contact resistance stable across repeated mating cycles, and the LCP housing holds up through reflow soldering without warping.
Mounting and Termination — Right-Angle SMT Edge-Mount
The 1-2213614-1 shares the same 0.157" (4.00 mm) pitch, 6 A current rating, gold-plated contacts, and hermaphroditic blade-and-receptacle design. The key difference: 1-2213614-1 supports both board-to-board and cable-to-board connections and ships in a Box, while 2213616-3 is Tape & Reel for SMT assembly and is specified for board-to-board only. If your line runs pick-and-place, the 2213616-3 feeds the reel; if you need cable mating or a boxed part for hand assembly, the 1-2213614-1 is the one.
