Here is the link to my SSR:

So I had this SSR for several months and have printed on it for probability 300+ hours. My replacement is the exact same SSR as I needed on fast to finish a print for a customer. When I find time I am going to look for a better replacement on Digikey or elsewhere. I attempted to look for one with the same specs but cannot find one.
