The 0.197\" (5.00mm) pitch gives each circuit enough room for the IDC slot and a solid latch lock, so the assembly stays put in a harness. Silver contact finish handles moderate mating cycles without the cost of gold — suited for interior equipment where the environment is dry and the connector isn't cycled daily. ## Key Specs That Drive the Fit Three positions in a single row — the BOM line count is the circuit count. IDC termination means you push the discrete wire into the slot with a simple hand press; no crimp die to buy. The latch lock keeps the plug mated to the matching receptacle under light vibration. Silver contacts are rated for the current the wire gauge can carry — the limiting factor is the wire, not the contact. Free-hanging (in-line) mounting, so no board footprint needed.","metaTitle":"TE Mark II 1-2178661-3 Plug, 3 Pos, 0.197\" Pitch, IDC","metaDescription":"TE Connectivity Mark II plug, 3-position, 0.197\" (5.00mm) pitch, IDC termination, silver contacts, ROHS3.
