Questions
Is there a KiCad symbol and footprint for the STCH03?
Yes. The symbol is EasyEDA_Cloud:STCH03TR 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 STCH03?
SO-8, with 8 pins. Its footprint is drawn on this page.
Where is the STCH03 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STCH03?
JLCPCB lists it as part C2970185, with 44 in stock; the sellers' links on this page open their listings.
What can replace the STCH03?
Parts like it in the library: the UC2843BD1013 by STMicroelectronics, the UC2844BD1013 by STMicroelectronics, the UC2845BD1013 by STMicroelectronics and the UC3843BD1 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
