Questions

Is there a KiCad symbol and footprint for the MMBT4401?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2E_3C and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MMBT4401?

SOT-23-3(TO-236-3), with 3 pins. Its footprint is drawn on this page.

Where is the MMBT4401 datasheet?

DIOTEC publishes it: the Datasheet link on this page opens it.

Where can I order the MMBT4401?

JLCPCB lists it as part C3200110, with 3,360 in stock; the sellers' links on this page open their listings.

What can replace the MMBT4401?

Parts like it in the library: the MMBT4401 by MDD, the ZXTP25020CFHTA by Diodes Incorporated, the BCX 42 E6327 by Infineon Technologies and the BC817-25 by DIOTEC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
