What is the meaning of the letter "N" in Altera part number EPF10K30AQI240-3N (in order to understand the differentiation between EPF10K30AQI240-3N to EPF10K30AQI240-3).

Hi SRich3,

Suffix 'N' is for RoHS-Compliant. Check the 'Lead Free Status / RoHS Status' below comparison for two parts from Digi-Key.
