Substitute Part Grouping Explanation

Substitution of the EP3SL50F780I4L with EP3SL50F780I4LG is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for logic element count, I/O configuration, RAM capacity, voltage supply range, operating temperature range, package type, and RoHS compliance status. The substitution is valid because the devices are functionally and electrically interchangeable at the component level. The primary distinction is product status: the original part is obsolete, while the substitute maintains active status with higher inventory availability.

Key parameters determining substitution validity:

• Logic Elements: 47,500 (identical)
• I/O Count: 488 (identical)
• RAM Bits: 2,184,192 (identical)
• Voltage Supply: 0.86V ~ 1.15V (identical)
• Operating Temperature: -40°C ~ 100°C (identical)
• Package: 780-FBGA (29x29) (identical)
• RoHS Compliance: Yes (identical)
