What he’s saying is he’s purchasing a part with a different pinout configuration than one of the original parts, because he doesn’t want to wait for one with the matching pinout to be in stock. If you get any of the bigger power transistors I linked, same pinout. If you get the C1815 part I linked, same part as originally installed, same pinout. Does that make sense? To be double sure, if you want, post a link to the parts you’re looking to purchase or purchased and I can verify whether or not they are direct drop-in replacements.
