Well, I searched, hard, with all the tricks I know, but came up with nothing. I am sure you have checked the part number, but maybe give it another look.
Clean it well. Then, take a little bit of white heat sink grease, or medical zinc cream, and wipe it over the numbers. Sometimes, that helps them to stand out. Use good light, a magnifying glass and younger eyes, if available;-)
I will follow, this thread, to continue to try to help. One option is to identify what the part does and try to find a part that will meet the requirements.
