Substitute Part Grouping Explanation

Substitution of the R5F104FDDFP#50 is determined by strict equivalence across the following critical parameters:

• Microcontroller Series & Core: RL78/G14 series with RL78 core processor
• Memory Configuration: 48KB FLASH program memory, 5.5KB RAM, 4KB EEPROM
• Processing Speed: 32MHz operation
• Electrical Specifications: 1.6V to 5.5V supply voltage range
• Peripheral Set: CSI, I2C, LINbus, UART/USART connectivity; DMA, LVD, POR, PWM, WDT peripherals
• I/O Count: 31 I/O pins
• Package: 44-LQFP (10x10) surface mount
• Environmental Compliance: ROHS3 compliance, REACH unaffected status

The R5F104FDDFP#50 differs from its substitute only in packaging configuration. The primary substitute maintains identical electrical, functional, and memory specifications while offering alternative packaging for procurement flexibility.

Parameter Comparison

Engineering Selection Recommendations

Both the R5F104FDDFP#50 and R5F104FDAFP#50 are active products from Renesas Electronics Corporation with identical electrical and functional specifications. Selection between these parts should be based on packaging requirements and supply chain availability. The R5F104FDAFP#50 is supplied in Tape & Reel (TR) packaging, which is standard for high-volume manufacturing and automated assembly processes. The R5F104FDDFP#50 may be supplied in alternative packaging configurations. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets. Moisture sensitivity level (MSL 3, 168 hours) applies uniformly to both parts, requiring identical handling and storage protocols. For applications requiring high-volume production with automated pick-and-place assembly, the Tape & Reel packaged variant (R5F104FDAFP#50) is the standard selection. For lower-volume or prototype applications, either part may be selected based on immediate availability and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Are R5F104FDDFP#50 and R5F104FDAFP#50 functionally identical?

A: Yes. Both parts are RL78/G14 series microcontrollers with identical core processor architecture, memory configuration (48KB FLASH, 5.5KB RAM, 4KB EEPROM), processing speed (32MHz), I/O count (31 pins), connectivity interfaces (CSI, I2C, LINbus, UART/USART), and peripheral set (DMA, LVD, POR, PWM, WDT). The difference is limited to packaging configuration.

Q: What is the primary difference between these substitute parts?

A: The R5F104FDAFP#50 is supplied in Tape & Reel (TR) packaging, while the R5F104FDDFP#50 may use alternative packaging. Both are housed in 44-LQFP (10x10) surface mount packages with identical pin configurations and electrical characteristics.
