Is there a KiCad symbol and footprint for the B3Q090?
Yes. The symbol is EasyEDA_Cloud:B3Q090 and the footprint EasyEDA_Cloud:DIO-DT-SMD_L6.8-W3.5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the B3Q090?
SMD-3P,6.8x3.5mm, with 3 pins. Its footprint is drawn on this page.
Where is the B3Q090 datasheet?
Bencent publishes it: the Datasheet link on this page opens it.
Where can I order the B3Q090?
JLCPCB lists it as part C730028, with 521 in stock; the sellers' links on this page open their listings.
What can replace the B3Q090?
Parts like it in the library: the B3Q090(ES) by ElecSuper, the B3Q420 by Bencent and the 3R090-3SQ-C by RUILON. Check their datasheets: a part that fits the footprint may still differ in its ratings.
