The PN4033 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The 2SC3438 (SOT-89), BSP43 (SOT-223), BSR43 (SOT-89), FMMTA06 (SOT-23), KST06 (SOT-23), MMBTA06 (SOT-23), PMBTA06 (SOT-23), PZTA06 (SOT-223) and SMBTA06 (SOT-23) is the SMD version of the PN4033 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the PN4033 with the BC538, ZTX454 or ZTX455.
