Questions
Is there a KiCad symbol and footprint for the IRFR321?
Yes. the footprint EasyEDA_Cloud:TO-252-2_L6.6-W6.1-P4.57-LS9.9-BR-CW, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the IRFR321?
TO-252(DPAK), with 3 pins. Its footprint is drawn on this page.
Where is the IRFR321 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the IRFR321?
JLCPCB lists it as part C3290883, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IRFR321?
Parts like it in the library: the NTD360N80S3Z by onsemi, the BRD7N65 by Foshan Blue Rocket Elec, the MOT5N50D by MOT and the OSG65R380DEF by ORIENTAL SEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
