Is there a KiCad symbol and footprint for the DOS18N03?
Yes. 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 DOS18N03?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where can I order the DOS18N03?
JLCPCB lists it as part C42386219, with 3,311 in stock; the sellers' links on this page open their listings.
What can replace the DOS18N03?
Parts like it in the library: the DOS30N03 by DOINGTER, the TSM150P04LCS RLG by Taiwan Semiconductor, the AO4409 by GOODWORK and the XR20P04S by XNRUSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
