Alternative Part for Altera P/N: 5M40ZE64C5N?

Does anyone know of a substitute part for Altera P/N: 5M40ZE64C5N, Digi-Key P/N: 544-2717-ND ? The lead time is 45 weeks which is unacceptable for my schedule. I do realize there is a IC shortage. Thanks!

Hello MiBeJo:

I’m sorry to say we do not have a stocking cross for 5M40ZE64C5N. Unfortunately, we don’t have any substitute to offer for this part.
