Questions

Is there a KiCad symbol and footprint for the FDN304P?

Yes. The symbol is Pinmap_Generic:Q_PMOS_1G_2S_3D and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the FDN304P?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the FDN304P datasheet?

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

Where can I order the FDN304P?

JLCPCB lists it as part C241803, with 8,692 in stock; the sellers' links on this page open their listings.

What can replace the FDN304P?

Parts like it in the library: the AO3400 by GOODWORK, the AP2300 by ALLPOWER, the AO3400A by Alpha & Omega Semiconductor and the AO3400A by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the FDN304P?

8 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
