Overview
The 2N4918 is a bipolar made by onsemi in a TO-225-3 package with 3 pins. -65℃~+150℃ 1A 30 30W 3MHz 40V 500uA 600mV PNP TO-225-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PNP_1E_2C_3B, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-225-3_L7.6-W2.8-P2.54-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C898326).

Is there a KiCad symbol and footprint for the 2N4918?
Yes. The symbol is Pinmap_Generic:Q_PNP_1E_2C_3B and the footprint EasyEDA_Cloud:TO-225-3_L7.6-W2.8-P2.54-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 2N4918?
TO-225-3, with 3 pins. Its footprint is drawn on this page.
Where is the 2N4918 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the 2N4918?
JLCPCB lists it as part C898326, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 2N4918?
Parts like it in the library: the BD180 by onsemi, the 2N4919 by onsemi, the 2N4922 by onsemi and the 2N4923 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
