Looks like this product is obsolete. What is the best replacement for this. Original is by STmicroelectronics. I must add that my device has 5 of these wired in parralell. I am replacing only one so I would think it would have to be as close a match as possible. Thank you ---

Hello, @Mitsu! Welcome to the forum. I did some checking and this looks like a near identical alternate: [497-2676-5-ND](https://www.digikey.com/en/products/detail/stmicroelectronics/STP80NF03L-04/603701?s=N4IgTCBcDaICwE4DsBaMA2J6UFYUDkAREAXQF8g) -Please note that this is a more or less temporary solution for sourcing replacements, while this item is still in stock for now, it being discontinued as well. The best active part number I could find was this: [497-13587-5-ND](https://www.digikey.com/en/products/detail/stmicroelectronics/STP105N3LL/3910825?s=N4IgTCBcDaICwE4DsBaAjAZgKwA5VZQDkAREAXQF8g) -However, it needs to be noted that this has a lower power rating than the original, so depending on the application you may need to review before using it. It’s not as exact a replacement as my first recommendation.
