Substitute Part Grouping Explanation

Substitution of the EP3SL50F484I4 is based on strict equivalence across the following critical parameters:

• Logic Architecture: Identical number of LABs/CLBs (1,900) and logic elements (47,500)
• I/O Configuration: Matching 296 I/O pin count
• Memory Capacity: Equivalent 2,184,192 total RAM bits
• Electrical Specifications: Identical supply voltage range (0.86V ~ 1.15V) and operating temperature range (-40°C ~ 100°C)
• Physical Package: Same 484-FBGA (23x23) footprint and surface mount configuration
• Compliance: RoHS compliant status maintained; MSL rating consistent at Level 3

The substitute part EP3SL50F484I4G differs only in packaging format (Tray vs. unspecified) and product status (Active vs. Obsolete), with no functional or electrical deviations.
