Overview

The LM2903DR is a comparator made by UMW in a SOP-8 package with 8 pins. -15V~-1V、1V~15V 0℃~+70℃ 1.3us 1mV 2 25nA 2V~30V 300ns 30V 400uA 5nA SOP-8 Comparators ROHS.

PCBKit's library has its KiCad symbol (Comparator:LM2903, from KiCad's library) and its footprint (Package_SO:SOP-8_3.76x4.96mm_P1.27mm, from KiCad's library), ready for a KiCad board. 155,246 are in stock at JLCPCB (part C668214). 2 open-source boards in 2 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the LM2903DR?

Yes. The symbol is Comparator:LM2903 and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2903DR?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM2903DR datasheet?

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

Where can I order the LM2903DR?

JLCPCB lists it as part C668214, with 155,246 in stock; the sellers' links on this page open their listings.

What can replace the LM2903DR?

Parts like it in the library: the LM393ADR by UMW, the LM393 by MSKSEMI, the LM393DRG by HANSCHIP semiconductor and the LM393 by IDCHIP. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM2903DR?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
