Board-fit and mating interface
The 9-146261-0-12: The 0.230" (5.84mm) mating pin length engages with a typical IDC socket or crimp receptacle, and the 0.090" (2.29mm) post sits flush through a 1.6mm board for wave solder.
Peer comparison: shrouded vs unshrouded
The closest functional second-source from the same manufacturer is 1-1871673-2 — a 4-position, 0.098" (2.50mm) pitch shrouded header with a detent lock and board lock, tin-plated contacts. That part is a different pitch and position count, so a direct swap requires a board spin. For a drop-in replacement within the AMPMODU Mod II family, stick with the same base product number 146261 and select the desired position count.
