Overview

The LM2903VD is an analog Comparator made by onsemi in a SOIC-8 package with 8 pins. -18V~-1V、1V~18V -40℃~+125℃ 1.5us 2 20nA 2V~36V 2mV 300ns 36V 400uA 5nA ESD protection 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. 11,338 are in stock at JLCPCB (part C91736).

Questions

Is there a KiCad symbol and footprint for the LM2903VD?

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 LM2903VD?

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

Where is the LM2903VD datasheet?

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

Where can I order the LM2903VD?

JLCPCB lists it as part C91736, with 11,338 in stock; the sellers' links on this page open their listings.

What can replace the LM2903VD?

Parts like it in the library: the LM2903MX by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
