Questions

Is there a KiCad symbol and footprint for the 2N5551?

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 2N5551?

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

Where is the 2N5551 datasheet?

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

Where can I order the 2N5551?

JLCPCB lists it as part C596306, with 561 in stock; the sellers' links on this page open their listings.

What can replace the 2N5551?

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.
