Overview

The LM393QT is a comparator made by STMicroelectronics in a DFN-8(2x2) package with 8 pins. -18V~-1V、1V~18V 0℃~+70℃ 1.3us 1mV 2 20nA 2V~36V 300ns 36V 3nA 450uA DTL、TTL、CMOS、ECL、MOS DFN-8(2x2) Comparators ROHS.

PCBKit's library has its KiCad symbol (Comparator:LM393, from KiCad's library) and its footprint (Package_DFN_QFN:DFN-8_2x2mm_P0.5mm, from KiCad's library), ready for a KiCad board. 2,176 are in stock at JLCPCB (part C2970927).

Questions

Is there a KiCad symbol and footprint for the LM393QT?

Yes. The symbol is Comparator:LM393 and the footprint Package_DFN_QFN:DFN-8_2x2mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM393QT?

DFN-8(2x2), with 8 pins. Its footprint is drawn on this page.

Where is the LM393QT datasheet?

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

Where can I order the LM393QT?

JLCPCB lists it as part C2970927, with 2,176 in stock; the sellers' links on this page open their listings.

What can replace the LM393QT?

Parts like it in the library: the LM2903Q2T by STMicroelectronics, the LM2903YQ3T by STMicroelectronics, the TSX3702IQ2T by STMicroelectronics and the TS883IQ2T by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
