Substitute Part Grouping Explanation
Substitution is strictly based on matching the following key electrical and mechanical parameters: core processor, core size, speed, connectivity, peripheral set, number of I/O, program memory size and type, EEPROM size, RAM size, supply voltage range, data converters, oscillator type, operating temperature range, mounting type, and physical package. Regulatory status is also considered, including RoHS and REACH compliance. Only parts with identical parameters across these fields are suitable as substitutes.
