Super ContributorHi,
Thank you for contacting Intel community.
Per ADV2007, the “G” suffix part numbers use the same silicon, product specifications, and are generally form, fit and function equivalent to the “N” suffix part numbers. Hence, there should be no concern on the functional different.
Per ADV1828, selected products will be converted to the leadfree SnAg1.8 solder bumps, replacing the 63/37 Sn-Pb bumps. This is to comply with EU Restriction of Hazardous Substances (RoHS) Directive Exemption 15 scope change. Hence that is the only changes to "G" suffix devices. Same device datasheet can be use.
