Questions

Is there a KiCad symbol and footprint for the HT7737?

Yes. The symbol is EasyEDA_Cloud:HT7733_C259880 and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT7737?

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

Where can I order the HT7737?

JLCPCB lists it as part C191570, with 0 in stock; the sellers' links on this page open their listings.

What can replace the HT7737?

Parts like it in the library: the XC9140A371MR-G by Torex Semiconductor, the XC9140A372MR-G by Torex Semiconductor, the XC9140C372MR-G by Torex Semiconductor and the XC9141A37CMR-G by Torex Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
