Overview

The BFU550R is a bipolar made by NXP Semiconductors in a SOT-143-4 package with 4 pins. -40℃~+150℃ 1 NPN 11GHz 12V 1nA 2V 450mW 50mA 95 NPN SOT-143-4 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1C_2B_3E_4E, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-143, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2687856).

Questions

Is there a KiCad symbol and footprint for the BFU550R?

Yes. The symbol is Pinmap_Generic:Q_NPN_1C_2B_3E_4E and the footprint Package_TO_SOT_SMD:SOT-143, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BFU550R?

SOT-143-4, with 4 pins. Its footprint is drawn on this page.

Where is the BFU550R datasheet?

NXP Semiconductors publishes it: the Datasheet link on this page opens it.

Where can I order the BFU550R?

JLCPCB lists it as part C2687856, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BFU550R?

Parts like it in the library: the BFP 193 E6327 by Infineon Technologies, the BFU550XAR by NXP Semiconductors, the BFU550XR215 by NXP Semiconductors and the BFP196E6327HTSA1 by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
