Overview

The LM2903DR is a comparator made by ROHM Semiconductor in a SOIC-8 package with 8 pins. -40℃~+125℃ 1.3us 1.3us 2 25nA 2V~36V 2mV 36V 5nA 800uA Open Collector TTL、CMOS、MOS 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. JLCPCB lists it (part C5443916).

Questions

Is there a KiCad symbol and footprint for the LM2903DR?

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 LM2903DR?

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

Where is the LM2903DR datasheet?

ROHM Semiconductor publishes it: the Datasheet link on this page opens it.

Where can I order the LM2903DR?

JLCPCB lists it as part C5443916, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM2903DR?

Parts like it in the library: the LM393D by onsemi, the LM393BID by Texas Instruments, the LM393DT by STMicroelectronics and the LM2903BID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
