Is there a KiCad symbol and footprint for the IS281K?
Yes. The symbol is EasyEDA_Cloud:MPS2733-1 and the footprint EasyEDA_Cloud:SOP-4_L4.4-W2.8-P1.27-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 IS281K?
SOIC-4-175mil, with 4 pins. Its footprint is drawn on this page.
Where is the IS281K datasheet?
Isocom Components publishes it: the Datasheet link on this page opens it.
Where can I order the IS281K?
JLCPCB lists it as part C6176655, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IS281K?
Parts like it in the library: the HMHA2801AR2 by onsemi, the CTH281GB(T1) by CT Micro International, the PS2801-1-F3 by Renesas Electronics and the PS2801C-1-F3 by Renesas Electronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
