Questions

Is there a KiCad symbol and footprint for the 2SC4138?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E and the footprint EasyEDA_Cloud:TO-3PN_L15.8-W5.0-P5.45-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 2SC4138?

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

Where is the 2SC4138 datasheet?

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

Where can I order the 2SC4138?

JLCPCB lists it as part C2907803, with 47 in stock; the sellers' links on this page open their listings.

What can replace the 2SC4138?

Parts like it in the library: the TIP35C by SPTECH, the 2SA1941-O(Q) by Toshiba, the MJW0281A by SPTECH and the MJW1302A by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
