Overview
The TF3402 is a MOSFET made by TF in a SOT-23 package with 3 pins. 1 N-channel 1.25W 1.6V 105mΩ@2.5V 30V 4A SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2S_3D, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 2,800 are in stock at JLCPCB (part C436866).

Questions
Is there a KiCad symbol and footprint for the TF3402?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2S_3D and 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 TF3402?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the TF3402 datasheet?
TF publishes it: the Datasheet link on this page opens it.
Where can I order the TF3402?
JLCPCB lists it as part C436866, with 2,800 in stock; the sellers' links on this page open their listings.
What can replace the TF3402?
Parts like it in the library: the SI2318 by GOODWORK, the 6P03 by GOODWORK, the AO3400AL by TECH PUBLIC and the AP3401BI by A Power microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
