Overview
The LM321A is an operational Amplifier made by WPMtek in a SOT-23-5 package with 5 pins. SOT-23-5 Operational Amplifier ROHS.
PCBKit's library has its KiCad symbol (Amplifier_Operational:LM321, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23-5, from KiCad's library), ready for a KiCad board. 1,786 are in stock at JLCPCB (part C55336051).

Is there a KiCad symbol and footprint for the LM321A?
Yes. The symbol is Amplifier_Operational:LM321 and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM321A?
SOT-23-5, with 5 pins. Its footprint is drawn on this page.
Where can I order the LM321A?
JLCPCB lists it as part C55336051, with 1,786 in stock; the sellers' links on this page open their listings.
What can replace the LM321A?
Parts like it in the library: the LMV321IDBV by Texas Instruments, the LM321MF011 by GREENMICRO, the LMV321-L by PIELENST and the LMV321AUIDBVR(UMW ) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
