Substitute Part Grouping Explanation

Substitution eligibility for the R5F100GLAFB#X0 is determined by strict equivalence across the following critical parameters: core processor architecture (RL78), core size (16-Bit), clock speed (32MHz), program memory capacity (512KB FLASH), RAM capacity (32K x 8), EEPROM capacity (8K x 8), supply voltage range (1.6V ~ 5.5V), I/O count (34 pins), package type (48-LQFP), and mounting method (Surface Mount). All substitute parts must maintain identical electrical and mechanical specifications to ensure functional compatibility within existing designs.

The substitute parts are grouped into two categories:

Direct Equivalent: Parts with identical part number suffix variations and packaging configurations that maintain 100% functional compatibility.

Parametric Equivalent: Parts from the same RL78/G13 series with matching core specifications but different series designations (RL78/G13A) that provide equivalent performance characteristics.
