Questions

Is there a KiCad symbol and footprint for the LM386?

Yes. The symbol is Amplifier_Audio:LM386 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 LM386?

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

Where is the LM386 datasheet?

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

Where can I order the LM386?

JLCPCB lists it as part C5157706, with 4,264 in stock; the sellers' links on this page open their listings.

What can replace the LM386?

Parts like it in the library: the BCT8002EOA-TR by BROADCHIP, the D2822M SOP8 by Silicore, the HAA8002D by Hynitron and the 8002B by LTKCHIP. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM386?

285 boards in 234 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
