Do all Pb Free RoHS compatible parts have a “Z” at the end of the part number?
No. Certain parts have already been introduced to the market as Pb Free RoHS compatible only, i.e. we do not offer a standard SnPb or SnPbAg finish on these parts. These part numbers do not carry a “Z” suffix, nonetheless these part numbers clearly state the finish on the data sheet and web product pages, and the branding on the parts will clearly indicate that the part is Pb Free RoHS compatible. (See question 7 below). The reasons we are not changing these parts numbers to include the Z are (a) the parts are already introduced and to change the naming would cause problems with customers and with current backlog, and (b) ultimately we hope to convert all parts to a Pb Free RoHS compatible only terminal finish and thus, in the end state, the Z will be a redundant character.
