Does Microchip use the same MSL rating for it’s parts?
For instance part MCP1825ST-1202E/DBTR-ND does have diffrent MSL ratings.
Yes Microchip is using diffrent MSL ratings for the same parts.
Why?:
Microchip MSL Ratings:
Microchip has several different assembly sites for their products and unfortunately different assembly sites sometimes rate the same IC package at different MSL ratings. In these cases, DigiKey adds a receiving note (if one is not already there) to treat parts to the highest MSL rating provided – either on the mfg label or what is listed in our system, no baking required. Please let me know if you have any questions.
