Is there a KiCad symbol and footprint for the 90N03?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-251_L6.6-W2.4-P2.30-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 90N03?
TO-251, with 3 pins. Its footprint is drawn on this page.
Where is the 90N03 datasheet?
TF publishes it: the Datasheet link on this page opens it.
Where can I order the 90N03?
JLCPCB lists it as part C845400, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 90N03?
Parts like it in the library: the AUIRLU3114Z by Infineon Technologies, the STD95NH02L-VB by VBsemi Elec, the SIF4N65F/TO-251T by SI and the SIF5N65F by SI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
