Is there a KiCad symbol and footprint for the FDN327N?
Yes. The symbol is Transistors:N-MOSFET-D 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 FDN327N?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the FDN327N datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FDN327N?
JLCPCB lists it as part C154560, with 5,642 in stock; the sellers' links on this page open their listings.
What can replace the FDN327N?
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.
