Q: What do the different IDT suffixes mean? A: "G" = Green. These parts exceed the RoHS requirements and eliminate halogens "LF" = Lead Free. These parts are RoHS compliant "8" = Reel. These are on a reel. If there is no "8" it will be tray or tube as listed on the IDT website "I" = Industrial temp rating. No "I" would call out commercial "M"= Military temp rating Other suffixes, for example SA, PH, Y, etc. call out package type i.e. SOIC, DIP, TSSOP, etc. See IDT website for more specific information
