NO! The 2N5088 and the BC547 are both in TO-92 packages, but they DO NOT have the same pinout: the physical location of the emitter and collector leads are swapped.
(It is intuitively obvious to the casual observer that there are six ways to map a transistor’s three standard connections to the three wire leads of a TO-92 package. The 2N5088 and the BC547 illustrate the two most common mappings - sometimes called “EBC” pinout and “CBE” pinout. Many transistors in the Japanese 2S**** numbering system, like the 2SC1815, use the “ECB” pinout. Transistors intended for RF applications, like the MPSH10, may use the “BEC” pinout. And there are probably parts that use the “CEB” and “BCE” pinouts, but I can’t name them off the top of my head.)
