Questions

Is there a KiCad symbol and footprint for the FSDL321?

Yes. The symbol is Regulator_Switching:FSDL321 and the footprint Package_DIP:DIP-8_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the FSDL321?

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

Where is the FSDL321 datasheet?

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

Where can I order the FSDL321?

JLCPCB lists it as part C3094681, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FSDL321?

Parts like it in the library: the FSBH0F70WANY by onsemi, the VIPER22ADIP-E by STMicroelectronics, the NCP1203P60 by onsemi and the NCP1200P40 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
