Substitute Part Grouping Explanation

Substitution of the R5F3650RDFB#V2 with the R5F3650RDFB#30 is based on complete parametric equivalence across all electrical and mechanical specifications. Both parts share identical core processor architecture (M16C/60), memory configuration (640KB FLASH, 8KB EEPROM, 47KB RAM), processing speed (32MHz), I/O count (85 pins), connectivity interfaces (EBI/EMI, I2C, SIO, UART/USART), peripheral set (DMA, LVD, POR, PWM, WDT), voltage supply range (2.7V ~ 5.5V), data converter specifications (A/D 26x10b, D/A 2x8b), operating temperature range (-40°C ~ 85°C), and physical packaging (100-LQFP, 14x14mm).

The primary distinction between these parts is product status: the R5F3650RDFB#V2 is obsolete, while the R5F3650RDFB#30 maintains active status. The suffix variation (#V2 versus #30) indicates different manufacturing or qualification batches within the same base product number (R5F3650).
