Part numbering - Fairchild FDS7066ASN3_NL


What does the suffix NL call out in Fairchild Semiconductor part numbers like FDS7066ASN3_NL?


NL = No lead (RoHS compliant) The NL was used while Fairchild products were transitioning from non-RoHS to RoHS. In most cases it is not used anymore as most of Fairchild’s products are RoHS compliant (so at this point FDS7066ASN3 and FDS7066ASN3_NL are the exact same part).
