Is there a KiCad symbol and footprint for the SN03ACPA?
Yes. 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 SN03ACPA?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the SN03ACPA datasheet?
OB publishes it: the Datasheet link on this page opens it.
Where can I order the SN03ACPA?
JLCPCB lists it as part C138873, with 3,388 in stock; the sellers' links on this page open their listings.
What can replace the SN03ACPA?
Parts like it in the library: the SDH8302STR by Hangzhou Silan Microelectronics, the UC3843B by UMW, the UC3843BDTR(XBLW) by XBLW and the UC3845BDTR(XBLW) by XBLW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
