Is there a KiCad symbol and footprint for the LM3402MR?
Yes. The symbol is Celestial_Driver_LED:TI LM3402MR and the footprint EasyEDA_Cloud:SO-8_L4.9-W3.9-P1.27-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM3402MR?
SO-8-EP, with 9 pins. Its footprint is drawn on this page.
Where is the LM3402MR datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM3402MR?
JLCPCB lists it as part C1554393, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM3402MR?
Parts like it in the library: the AL8843SP by Diodes Incorporated, the AL8862SP by Diodes Incorporated, the PAM2808BLBR by Diodes Incorporated and the AL8822SP by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
