Is there a KiCad symbol and footprint for the BU9873FVT-GE2?
Yes. The symbol is EasyEDA_Cloud:BU9873FVM-GTTR and the footprint Package_SO:TSSOP-8_4.4x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BU9873FVT-GE2?
TSSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the BU9873FVT-GE2 datasheet?
ROHM Semiconductor publishes it: the Datasheet link on this page opens it.
Where can I order the BU9873FVT-GE2?
JLCPCB lists it as part C2669516, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BU9873FVT-GE2?
Parts like it in the library: the MCP7940M-I/ST by Microchip Technology, the MCP79411-I/ST by Microchip Technology, the MC100LVEP11DT by onsemi and the ISL12026IVZ by Renesas Electronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
