I have found this listed on some cross reference lists (from early 2000's), but when trying to cross reference it today (or, rather, the listed equivs for the 2023) my searches all come back with the CR 2025 which is only 0.2 mm thicker. I don't think it's a typing error as the lists I have that show it are from different sources.
