Questions

Is there a KiCad symbol and footprint for the TM1621?

Yes. The symbol is EasyEDA_Cloud:TM1621_C41326 and the footprint EasyEDA_Cloud:SSOP-48_L16.0-W7.6-P0.64-LS10.7-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM1621?

SSOP-48-300mil, with 48 pins. Its footprint is drawn on this page.

Where is the TM1621 datasheet?

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

Where can I order the TM1621?

JLCPCB lists it as part C95857, with 330 in stock; the sellers' links on this page open their listings.

What can replace the TM1621?

Parts like it in the library: the HT1621BM/TR by HGSEMI and the FM1906 by Shenzhen Fuman Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
