The 1-wall shrouding and friction lock keep the mated pair aligned and resistant to vibration without needing a separate locking clip.
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.
