Questions
Is there a KiCad symbol and footprint for the L9857-LF?
Yes. The symbol is EasyEDA_Cloud:L9857-TR-LF 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 L9857-LF?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where can I order the L9857-LF?
JLCPCB lists it as part C2677119, with 0 in stock; the sellers' links on this page open their listings.
What can replace the L9857-LF?
Parts like it in the library: the 3520DESA/T by VP, the 2EDN7534FXTMA1 by Infineon Technologies, the IR2184SPBF by Infineon Technologies and the IRS2005SPBF by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
