Is there a KiCad symbol and footprint for the 2SC4618?
Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2E_3C and the footprint Package_TO_SOT_SMD:SOT-523, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 2SC4618?
SOT-523, with 3 pins. Its footprint is drawn on this page.
Where is the 2SC4618 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the 2SC4618?
JLCPCB lists it as part C19269056, with 1,478 in stock; the sellers' links on this page open their listings.
What can replace the 2SC4618?
Parts like it in the library: the 2SC4617TLR by ROHM Semiconductor, the 2SC4617R by Shikues, the DTC114EE by Shikues and the MMBT5401T by CBI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
