Questions
Is there a KiCad symbol and footprint for the HT1621?
Yes. the footprint Package_QFP:LQFP-44_10x10mm_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT1621?
LQFP-44(10x10), with 44 pins. Its footprint is drawn on this page.
Where can I order the HT1621?
JLCPCB lists it as part C2848090, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HT1621?
Parts like it in the library: the ATMEGA32A-AU by Microchip Technology, the STC89C52RC-40I by STC, the STM8S105S4T6C by STMicroelectronics and the PIC16F1939-I/PT by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
