Questions

Is there a KiCad symbol and footprint for the AL1791AFE?

Yes. The symbol is EasyEDA_Cloud:AL1792AFE-13 and the footprint EasyEDA_Cloud:U-DFN4030-14_L4.0-W3.0-P0.50-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AL1791AFE?

UDFN-14-EP(4x3), with 15 pins. Its footprint is drawn on this page.

Where is the AL1791AFE datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the AL1791AFE?

JLCPCB lists it as part C156300, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AL1791AFE?

Parts like it in the library: the FAN5333ASX by onsemi, the FAN5333BSX by onsemi, the MP3306EG-LF-P by Monolithic Power Systems and the STI9287B by TMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
