ContributorHi Michael,
Thank you for contacting Intel Community. For your information, the common part number with the ‘N’ suffix at the last character represented the RoHS compliance (RoHS 6/6) part. For example, EPM7192SQC160-10N which ends with the ‘N’ suffix indicated it is RoHS compliant whereas without the ‘N’ suffix would be RoHS's non-compliant part. For further details, please click on the RoHS Compliant link for further details: https://www.intel.com/content/www/us/en/products/programmable/temperature.html
For EPM7192SQC160-10N, it is a lead-free product that contains Sn-3-4% silver(Ag)-0.5% Cu solder balls according to this white paper below:

Thank you

New ContributorI had previously read that paper but it did not provide a definitive answer regarding the specific lead finish used on the EPM7192SQC160-10N. The information that I have indicates that the EPM7192SQC160-10N is in a leaded package (not in a BGA package). The paper indicates that "the industry has accepted the use of eutectic Sn-Ag-Cu for solder balls and either matte Sn or Sn-2%Cu for lead finishes". Given that the information I have indicates that this is a leaded package the paper indicates the use of "either matte Sn or Sn-2%Cu for lead finishes". I had previously read this paper and was wanting to know if the EPM7192SQC160-10N used a matte Sn lead finish, or a Sn-2%Cu lead finish, or both (or either) lead finishes depending upon the manufacturing run.
