Is there a KiCad symbol and footprint for the LLCC68IMLTRT?
Yes. The symbol is EasyEDA_Cloud:LLCC68IMLTRT and the footprint EasyEDA_Cloud:QFN-24_L4.0-W4.0-P0.50-BL-EP2.6, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LLCC68IMLTRT?
QFN-24-EP(4x4), with 25 pins. Its footprint is drawn on this page.
Where is the LLCC68IMLTRT datasheet?
SEMTECH publishes it: the Datasheet link on this page opens it.
Where can I order the LLCC68IMLTRT?
JLCPCB lists it as part C5120261, with 17,221 in stock; the sellers' links on this page open their listings.
What can replace the LLCC68IMLTRT?
Parts like it in the library: the SX1250IMLTRT by SEMTECH and the MXL608-AG-T by MaxLinear. Check their datasheets: a part that fits the footprint may still differ in its ratings.
