Overview

The LM321 is an operational Amplifier made by MSKSEMI in a SOT-23-5 package with 5 pins. -18V~18V 0℃~+70℃ 1 1.2MHz 250nA 3V~36V 500uA 50nA 5mV 80dB Built-in compensation 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. 134,851 are in stock at JLCPCB (part C5252901).

Questions

Is there a KiCad symbol and footprint for the LM321?

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 LM321?

SOT-23-5, with 5 pins. Its footprint is drawn on this page.

Where is the LM321 datasheet?

MSKSEMI publishes it: the Datasheet link on this page opens it.

Where can I order the LM321?

JLCPCB lists it as part C5252901, with 134,851 in stock; the sellers' links on this page open their listings.

What can replace the LM321?

Parts like it in the library: the LMV321IDBVR by UMW, the LM321MF by UMW, the TLV9061IDBV by Texas Instruments and the LM321-TR by Gainsil. Check their datasheets: a part that fits the footprint may still differ in its ratings.
