Questions

Is there a KiCad symbol and footprint for the HT66F30?

Yes. The symbol is EasyEDA_Cloud:HT66F30_C189807 and the footprint Package_SO:SOIC-24W_7.5x15.4mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT66F30?

SOP-24-300mil, with 24 pins. Its footprint is drawn on this page.

Where is the HT66F30 datasheet?

Holtek Semicon publishes it: the Datasheet link on this page opens it.

Where can I order the HT66F30?

JLCPCB lists it as part C189807, with 3 in stock; the sellers' links on this page open their listings.

What can replace the HT66F30?

Parts like it in the library: the HC89F302C-SOP24-T by Shanghai Holychip Elec, the EM78P374NSO24 by ELAN Microelectronics, the HT46F49E-24SOP by Holtek Semicon and the HT48R065B-24SOP by Holtek Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
