Questions

Is there a KiCad symbol and footprint for the SQ9912MST?

Yes. The symbol is EasyEDA_Cloud:AL9910-5S-13 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SQ9912MST?

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

Where is the SQ9912MST datasheet?

Sequoia Microelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the SQ9912MST?

JLCPCB lists it as part C254128, with 242 in stock; the sellers' links on this page open their listings.

What can replace the SQ9912MST?

Parts like it in the library: the AL1692S by Diodes Incorporated, the AL3353S by Diodes Incorporated, the AL8853S by Diodes Incorporated and the KP116SPA by Kiwi Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
