Questions

Is there a KiCad symbol and footprint for the TM1628?

Yes. The symbol is EasyEDA_Cloud:TM1628 and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM1628?

SOIC-28-300mil, with 28 pins. Its footprint is drawn on this page.

Where is the TM1628 datasheet?

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

Where can I order the TM1628?

JLCPCB lists it as part C37175, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TM1628?

Parts like it in the library: the TM1638 by TM, the TM1640(TA2103) by TM, the TM1628A by TM and the GN1638 by GN Semic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
