Substitute Part Grouping Explanation

Substitution of the R5F104FEGFP#10 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part R5F104FEGFP#30 qualifies as a direct parametric equivalent based on the following criteria:

Core Processor Architecture: Both parts utilize the identical RL78 core processor at 16-bit configuration with 32MHz operating frequency.

Memory Configuration: Both devices provide identical program memory (64KB FLASH), EEPROM (4K x 8), and RAM (5.5K x 8) specifications.

I/O and Peripheral Set: Both parts feature 31 I/O pins with identical connectivity options (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LVD, POR, PWM, WDT).

Electrical Specifications: Both parts operate within the same voltage supply range (2.4V ~ 5.5V) and feature identical analog-to-digital converter specifications (A/D 10x8/10b).

Package and Environmental Compliance: Both parts are housed in 44-LQFP (10x10) surface mount packages with identical operating temperature range (-40°C ~ 105°C), RoHS3 compliance, and MSL rating (3, 168 Hours).

The difference between R5F104FEGFP#10 and R5F104FEGFP#30 relates to packaging tray designation only, which does not affect functional or electrical equivalence.
