Through-hole mounting with a 0.092\" (2.34mm) post length — the solder tails sit through the board and are wave-soldered. Insulation height is 0.322\" (8.18mm) above the board surface, so plan for that z-height clearance under the mating receptacle or above adjacent components. ## How this compares to the 2- and 4-position siblings The 1718561003 (3 positions) is the middle option between the 2-position 1718561002 and the 4-position 1718561004. If your BOM needs exactly three circuits, this is the one; if you need two or four, those siblings are drop-in replacements on the same footprint pattern.","metaTitle":"Molex 1718561003 KK254 Header, 3-Pos, 2.54mm, Friction Lock","metaDescription":"Molex 1718561003 KK254 vertical header, 3 circuits, 0.100\" (2.54mm) pitch, gold mating finish, friction lock.
