Overview

The LM2903BID is a comparator made by Texas Instruments in a SOIC-8 package with 8 pins. -40℃~+125℃ 0.5nA 1us 1us 2 2V~36V 3.5nA 36V 370uV 400uA ESD protection Open-drain TTL、CMOS SOIC-8 Comparators ROHS.

PCBKit's library has its KiCad symbol (Comparator:LM2903, from KiCad's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 145,352 are in stock at JLCPCB (part C2869804).

Questions

Is there a KiCad symbol and footprint for the LM2903BID?

Yes. The symbol is Comparator:LM2903 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2903BID?

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

Where is the LM2903BID datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM2903BID?

JLCPCB lists it as part C2869804, with 145,352 in stock; the sellers' links on this page open their listings.

What can replace the LM2903BID?

Parts like it in the library: the LM393D by onsemi, the LM393BID by Texas Instruments, the LM393DT by STMicroelectronics and the LM293D by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
