Frequently asked questions
Can 71256SA12PZG replace 71256SA12PZ?
The suffix 'G' typically indicates a lead-free / RoHS-compliant finish. The 71256SA12PZG is functionally identical to the 71256SA12PZ in terms of memory size, organisation, access time, and package, so it is a drop-in replacement for the non-RoHS variant.
