Substitute Part Grouping Explanation

Substitute parts for the R5F104BCAFP#10 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Core Substitution Parameters:

• Identical processor architecture (RL78 core)
• Matching memory configuration (32KB FLASH, 4KB EEPROM, 4KB RAM)
• Identical operating frequency (32MHz)
• Identical supply voltage range (1.6V ~ 5.5V)
• Identical peripheral set (DMA, LVD, POR, PWM, WDT)
• Identical connectivity options (CSI, I2C, LINbus, UART/USART)
• Identical I/O count (22 pins)
• Identical package format (32-LQFP, 7x7mm)
• Identical data converter specifications (A/D 8x8/10b)

The R5F104BCAFP#30 qualifies as a parametric equivalent substitute. The difference between these part numbers relates to packaging configuration (tray variant designation) rather than electrical or functional specifications. Both parts maintain identical Active product status and compliance certifications.
