Hi everyone! I'm new to the forum but I've been following it for a while. I have a question for all of you knowledgeable folks out there. I have been troubleshooting and repairing a lot of our Cisco power supplies that have went out and I have a few that are a different model that have bad Mosfets part number IXFH12N50. I am having a hard time finding them and would like your help finding a suitable replacement. I can troubleshoot and repair, but when it gets into needing to replace a part like this with a different model, I want to make sure I'm choosing the right thing. It's a To-247 case. I appreciate any help you can give me!
