Questions

Is there a KiCad symbol and footprint for the FSFM261N?

Yes. The symbol is EasyEDA_Cloud:FSFM261N and the footprint EasyEDA_Cloud:PDIP-8_L9.3-W6.4-P2.54-LS7.9-BL-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the FSFM261N?

MDIP-8, with 8 pins. Its footprint is drawn on this page.

Where is the FSFM261N datasheet?

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

Where can I order the FSFM261N?

JLCPCB lists it as part C3094583, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FSFM261N?

Parts like it in the library: the CS3842BGN8 by onsemi, the FAN7530N by onsemi and the FSDH0165D by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
