Questions

Is there a KiCad symbol and footprint for the MF-R020?

Yes. The symbol is Device:Polyfuse and the footprint EasyEDA_Cloud:FUSE-TH_L7.1-W3.8-P5.10-D0.8, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MF-R020?

插件,P=5.1mm, with 2 pins. Its footprint is drawn on this page.

Where is the MF-R020 datasheet?

Bourns publishes it: the Datasheet link on this page opens it.

Where can I order the MF-R020?

JLCPCB lists it as part C208470, with 2,235 in stock; the sellers' links on this page open their listings.

What can replace the MF-R020?

Parts like it in the library: the JK250-040U by Jinrui Electronic Materials Co., the JK250-080U by Jinrui Electronic Materials Co., the A250-120 by Shenzhen JDT Fuse and the JK250-090U by Jinrui Electronic Materials Co.. Check their datasheets: a part that fits the footprint may still differ in its ratings.
