Is there a KiCad symbol and footprint for the L9904?
Yes. The symbol is EasyEDA_Cloud:L9904TR and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L9904?
SO-20-300mil, with 20 pins. Its footprint is drawn on this page.
Where is the L9904 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L9904?
JLCPCB lists it as part C2150554, with 10 in stock; the sellers' links on this page open their listings.
What can replace the L9904?
Parts like it in the library: the L297D013 by STMicroelectronics, the DRV8803DW by Texas Instruments, the DRV8805DW by Texas Instruments and the DRV8804DW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
