Questions

Is there a KiCad symbol and footprint for the CMS1620?

Yes. The symbol is EasyEDA_Cloud:TM1620(TA1323C) and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CMS1620?

SOP-20-300mil, with 20 pins. Its footprint is drawn on this page.

Where is the CMS1620 datasheet?

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

Where can I order the CMS1620?

JLCPCB lists it as part C541892, with 0 in stock; the sellers' links on this page open their listings.

What can replace the CMS1620?

Parts like it in the library: the CMS1616 by Cmsemicon, the CMS1617 by Cmsemicon, the CMS1628 by Cmsemicon and the TA6932 by TM. Check their datasheets: a part that fits the footprint may still differ in its ratings.
