Questions

Is there a KiCad symbol and footprint for the ASH18E2U?

Yes. the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ASH18E2U?

SOT-23, with 5 pins. Its footprint is drawn on this page.

Where is the ASH18E2U datasheet?

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

Where can I order the ASH18E2U?

JLCPCB lists it as part C7419248, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ASH18E2U?

Parts like it in the library: the SM18C by MDD, the SESMC18 by SEMIWARE, the SM18 by Wild Goose and the BST23C182V by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
