Is there a KiCad symbol and footprint for the KXT331LHS?
Yes. The symbol is EasyEDA_Cloud:SPEH110100 and the footprint EasyEDA_Cloud:SW-SMD_L3.0-W2.0-LS3.5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the KXT331LHS?
SMD,3x2mm, with 2 pins. Its footprint is drawn on this page.
Where is the KXT331LHS datasheet?
C&K publishes it: the Datasheet link on this page opens it.
Where can I order the KXT331LHS?
JLCPCB lists it as part C221822, with 7,670 in stock; the sellers' links on this page open their listings.
What can replace the KXT331LHS?
Parts like it in the library: the R-667995 by Mitsumi Electric, the EVP-AWCD2A by Panasonic, the KXT321LHS by C&K and the KXT311LHS by C&K. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the KXT331LHS?
2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
