Questions

Is there a KiCad symbol and footprint for the 2N3447?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2E_3C_4C and the footprint EasyEDA_Cloud:TO-3_L39.4-W26.7-P10.92-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 2N3447?

TO-3, with 4 pins. Its footprint is drawn on this page.

Where is the 2N3447 datasheet?

SPTECH publishes it: the Datasheet link on this page opens it.

Where can I order the 2N3447?

JLCPCB lists it as part C2907857, with 10 in stock; the sellers' links on this page open their listings.

What can replace the 2N3447?

Parts like it in the library: the 2N3773 by SPTECH, the BD142 by SPTECH, the MJ15015 by onsemi and the 2N5686 by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
