Questions

Is there a KiCad symbol and footprint for the COS129U?

Yes. The symbol is EasyEDA_Cloud:COS620BRZ and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the COS129U?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the COS129U datasheet?

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

Where can I order the COS129U?

JLCPCB lists it as part C5358243, with 40 in stock; the sellers' links on this page open their listings.

What can replace the COS129U?

Parts like it in the library: the TPA1286U-SO1R by 3PEAK, the COS8221ARZ by COSINE, the AD620BRZ-RL-JSM by JSMSEMI and the COS128U by COSINE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
