Is there a KiCad symbol and footprint for the FDS8449?
Yes. The symbol is EasyEDA_Cloud:AO4447A and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FDS8449?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the FDS8449 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FDS8449?
JLCPCB lists it as part C188510, with 0 in stock; the sellers' links on this page open their listings.
What can replace the FDS8449?
Parts like it in the library: the AO4485 by Alpha & Omega Semiconductor, the AO4264E by Alpha & Omega Semiconductor, the AO4480 by Alpha & Omega Semiconductor and the SI4401FDY by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the FDS8449?
