That saves a BOM line and a pick-and-place step in manual assembly, and it eliminates the risk of a cracked washer or uneven thermal paste application. The trade-off is higher thermal resistance to the case compared to a standard TO-220 with a mica washer, so the 35 W dissipation ceiling is the practical limit for continuous operation. Mounting torque and flatness matter here — the full-pack body is thicker, and overtightening can crack the epoxy. The STF19NM65N is listed as Obsolete. ST has moved on from this MDmesh II generation, and there is no active last-time-buy window.

For a pin-compatible drop-in, you would need to compare the TO-220FP footprint and key parametrics (650 V Vdss, 15.5 A Id, 270 mΩ Rds(on) at 10 V) against current MDmesh M5 or MDmesh K5 series parts from ST.
