Questions
Is there a KiCad symbol and footprint for the TF3400B?
Yes. the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TF3400B?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the TF3400B datasheet?
TF publishes it: the Datasheet link on this page opens it.
Where can I order the TF3400B?
JLCPCB lists it as part C3029140, with 1,519 in stock; the sellers' links on this page open their listings.
What can replace the TF3400B?
Parts like it in the library: the TF3400 by TF, the LX3400L by ChipLink Tech, the CMN3400M by Cmos and the FH3415B++ by XIN FEI HONG. Check their datasheets: a part that fits the footprint may still differ in its ratings.
