The TO-220-3 through-hole package with a metal tab is the standard for medium-power through-hole switching.
The STP40NS15 is listed as Obsolete by STMicroelectronics. For BOM lines that require this exact order code, procurement goes through the surplus and independent distribution channel. There is no factory lead time to manage, but the supply window depends on broker inventory depth.
For a pin-compatible alternative, look for a 150 V, 40 A N-channel MOSFET in TO-220 with similar Rds(on) and gate charge — but verify the footprint, drive voltage, and switching performance against the application.
