Questions

Is there a KiCad symbol and footprint for the BU406?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E and the footprint Package_TO_SOT_THT:TO-220-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BU406?

TO-220-3L, with 3 pins. Its footprint is drawn on this page.

Where is the BU406 datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the BU406?

JLCPCB lists it as part C81221, with 554 in stock; the sellers' links on this page open their listings.

What can replace the BU406?

Parts like it in the library: the TIP42C by STMicroelectronics, the TIP147 by Jiangsu Changjing Electronics Technology (CJ), the MJE13007 by onsemi and the MJE2955 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
