Is there a KiCad symbol and footprint for the EL357B?
Yes. The symbol is EasyEDA_Cloud:BL3H7B and the footprint EasyEDA_Cloud:SMD-4_L4.6-W3.7-P2.54-LS7.0-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the EL357B?
SOP-4, with 4 pins. Its footprint is drawn on this page.
Where is the EL357B datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the EL357B?
JLCPCB lists it as part C17702877, with 7,277 in stock; the sellers' links on this page open their listings.
What can replace the EL357B?
Parts like it in the library: the EL357C by GOODWORK, the EL357C by HXY MOSFET, the PC357C by GOODWORK and the PS2701-1-L by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
