Series footprint and position ladder
Within the AMPMODU Mod II 87230 series the 1-87230-3's 26 positions sit between the 20-position 1-87230-1 and the 30-position 1-87230-4 — the 0.100" pitch, dual-row layout, and unshrouded profile are shared across the series, so match the position count to circuit count.
