Questions

Is there a KiCad symbol and footprint for the PAM8403DR?

Yes. The symbol is Amplifier_Audio:PAM8403D and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PAM8403DR?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the PAM8403DR datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the PAM8403DR?

JLCPCB lists it as part C4990933, with 0 in stock; the sellers' links on this page open their listings.

What can replace the PAM8403DR?

Parts like it in the library: the PAM8406DR by Diodes Incorporated, the IRS2092STRPBF by Infineon Technologies, the IRS20957STRPBF by Infineon Technologies and the PAM8403 by Slkor. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the PAM8403DR?

53 boards in 42 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
