Questions

Is there a KiCad symbol and footprint for the HT494ARTZ?

Yes. The symbol is EasyEDA_Cloud:HT494ARTZ and the footprint Package_SO:TSSOP-16_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT494ARTZ?

TSSOP-16, with 16 pins. Its footprint is drawn on this page.

Where is the HT494ARTZ datasheet?

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

Where can I order the HT494ARTZ?

JLCPCB lists it as part C5366659, with 167 in stock; the sellers' links on this page open their listings.

What can replace the HT494ARTZ?

Parts like it in the library: the SG3525MT/TR by HGSEMI, the SG2525MT/TR by HGSEMI, the LM5025CMTCX by Texas Instruments and the LM5026MTX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
