Is there a KiCad symbol and footprint for the IS181B-AXW?
Yes. the footprint EasyEDA_Cloud:SOP-4_L3.6-W4.4-P2.54-LS7.0-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the IS181B-AXW?
SOP-4, with 4 pins. Its footprint is drawn on this page.
Where is the IS181B-AXW datasheet?
ISOMICRON publishes it: the Datasheet link on this page opens it.
Where can I order the IS181B-AXW?
JLCPCB lists it as part C42432156, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IS181B-AXW?
Parts like it in the library: the PC357C by HXY MOSFET, the MPC354(T1)-GV by miracle, the CT354(T1) by CT Micro International and the CT354(V)(T1) by CT Micro International. Check their datasheets: a part that fits the footprint may still differ in its ratings.
