The 5-534204-9: 20 positions arranged in two rows of 10, with all positions loaded.
Supplied in tube packaging, ROHS3 compliant. The base product number is 534204, which covers the full family of 0.100" pitch AMPMODU Mod II receptacles.
The closest functional sibling is 5-534204-4, which shares the same pitch, row spacing, mounting style, and plating but carries 30 positions instead of 20. If your BOM calls for 30 positions, 5-534204-4 is a direct swap in footprint and mating interface. Other siblings in the same series — 5-532956-1 (12 positions) and 5-532956-7 (40 positions) — share identical pitch, row spacing, and gold plating, differing only in position count. All are active and use the same kinked-pin, right-angle through-hole termination.
