Is there a KiCad symbol and footprint for the TM1931?
Yes. The symbol is EasyEDA_Cloud:IS31FL3218-GRLS2-TR and the footprint Package_SO:SOIC-24W_7.5x15.4mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TM1931?
SOP-24, with 24 pins. Its footprint is drawn on this page.
Where is the TM1931 datasheet?
TM publishes it: the Datasheet link on this page opens it.
Where can I order the TM1931?
JLCPCB lists it as part C5174523, with 74 in stock; the sellers' links on this page open their listings.
What can replace the TM1931?
Parts like it in the library: the AIP1624 by Wuxi I-core Elec, the STLED316SM by STMicroelectronics, the TM1639(TA1319) by TM and the STP16CP05M by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
