Questions
Is there a KiCad symbol and footprint for the BC33725BU?
Yes. The symbol is Pinmap_Generic:Q_NPN_1C_2B_3E and the footprint EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P1.27-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BC33725BU?
TO-92-3L, with 3 pins. Its footprint is drawn on this page.
Where is the BC33725BU datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BC33725BU?
JLCPCB lists it as part C896666, with 2,213 in stock; the sellers' links on this page open their listings.
What can replace the BC33725BU?
Parts like it in the library: the ZTX455STZ by Diodes Incorporated, the 2SD1857-Q by Foshan Blue Rocket Elec, the KSA928A by Foshan Blue Rocket Elec and the PN2907ATF by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BC33725BU?
