Is there a KiCad symbol and footprint for the EX3400B?
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 EX3400B?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the EX3400B datasheet?
Existar publishes it: the Datasheet link on this page opens it.
Where can I order the EX3400B?
JLCPCB lists it as part C48581020, with 730 in stock; the sellers' links on this page open their listings.
What can replace the EX3400B?
Parts like it in the library: the AO3400A by UMW, the AO3400 by Guangdong Hottech, the IRLML6344TRPBF-HXY by HXY MOSFET and the MDD3400 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
