Questions
Is there a KiCad symbol and footprint for the IRFD321?
Yes. the footprint Package_DIP:DIP-4_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the IRFD321?
DIP-4, with 4 pins. Its footprint is drawn on this page.
Where is the IRFD321 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the IRFD321?
JLCPCB lists it as part C3288353, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IRFD321?
Parts like it in the library: the IRFD1Z3 by Texas Instruments, the IRFD310 by Texas Instruments, the IRFD111 by Texas Instruments and the IRFD121 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
