Position count ladder: 28, 32, and 40 circuits
Within the ICA series the 40-position ICA-640-STT sits above the 28-position ICA-628-SGT and the 32-position ICA-632-STT — all share the 0.100" pitch, 0.6" row spacing, tin mating contacts, and through-hole termination, so the footprint and board layout are consistent across the three counts.
