Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on electrical, mechanical, and compliance parameters. For the embedded microcontroller category, allowable substitutes must match in core architecture, memory size, speed, connectivity, peripherals, supply voltage, package type, and regulatory compliance (RoHS, REACH, MSL). Only components where these parameters are explicitly identical are designated as substitutes.
