Is there a KiCad symbol and footprint for the 3DD303C?
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 3DD303C?
TO-3, with 4 pins. Its footprint is drawn on this page.
Where is the 3DD303C datasheet?
SPTECH publishes it: the Datasheet link on this page opens it.
Where can I order the 3DD303C?
JLCPCB lists it as part C2907845, with 25 in stock; the sellers' links on this page open their listings.
What can replace the 3DD303C?
Parts like it in the library: the 2N3773 by SPTECH, the 2SC2246 by SPTECH, the BD142 by SPTECH and the MJ15015 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
