The 2106091-4: At 1.50 mm pitch and 5 circuits in a single row, the board footprint is compact — the 0.059-inch pitch sets the trace channel width and the keep-out zone around the shrouded 4-wall housing.
Where the Mini CT fits alongside the CT series
The Mini CT series runs at 1.50 mm pitch, tighter than the 2.00 mm pitch of the standard CT series (1-292164-1). The 5-circuit count here is a single-row layout; the CT peer offers 11 circuits at a wider pitch but in a through-hole right-angle package — not a direct footprint swap.
