Direct answer: Eagle lists the E555 Diamond board for the Eagle 2000 family, but the exact replacement board must match the operator revision.
#ad Check the E555 listing and revision note
The currently sold E555 SKU I found is explicitly described for pre-January-2016 non-UL operators. Treat “E555 fits Eagle 2000” as a family-level starting point, not enough information to order a board.
