Overview

The 2N4401 is a bipolar made by STMicroelectronics in a TO-92 package with 3 pins. 1 NPN 100 100nA 250MHz 40V 600mA 625mW 6V 750mV NPN TO-92 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1E_2B_3C, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_THT:TO-92L, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C118540).

Questions

Is there a KiCad symbol and footprint for the 2N4401?

Yes. The symbol is Pinmap_Generic:Q_NPN_1E_2B_3C and the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 2N4401?

TO-92, with 3 pins. Its footprint is drawn on this page.

Where is the 2N4401 datasheet?

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

Where can I order the 2N4401?

JLCPCB lists it as part C118540, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 2N4401?

Parts like it in the library: the 2N2222A by Slkor, the 2N2222A-338 by ALJ, the 2N5401H-98 by ALJ and the SS8050D331 by ALJ. Check their datasheets: a part that fits the footprint may still differ in its ratings.
