Substitute Part Grouping Explanation

Substitute parts for the R5F104FCDFP#10 are identified based on strict parametric equivalence within the RL78/G14 microcontroller family. The substitution logic is governed by the following critical parameters that must remain identical:

Core Electrical Parameters:

• Core Processor: RL78
• Core Size: 16-Bit
• Speed: 32MHz
• Program Memory Size: 32KB (32K x 8) FLASH
• EEPROM Size: 4K x 8
• RAM Size: 4K x 8
• Voltage Supply Range: 1.6V ~ 5.5V
• Data Converters: A/D 10x8/10b
• Number of I/O: 31

Connectivity & Peripherals:

• Connectivity: CSI, I2C, LINbus, UART/USART
• Peripherals: DMA, LVD, POR, PWM, WDT
• Oscillator Type: Internal

Physical & Environmental Parameters:

• Mounting Type: Surface Mount
• Package / Case: 44-LQFP (10x10)
• Operating Temperature: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)
• REACH Status: REACH Unaffected

The identified substitutes differ only in packaging designation (suffix #10 versus #30), which reflects tape and reel configuration or quantity per reel specifications. These variations do not affect electrical performance, pin configuration, or functional capability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—R5F104FCDFP#10, R5F104FCAFP#10, and R5F104FCAFP#30—are functionally equivalent microcontrollers within the RL78/G14 series and maintain identical electrical specifications, pin configurations, and performance characteristics.

Compliance & Certification: All substitute parts carry ROHS3 compliance certification and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. Moisture Sensitivity Level 3 (168 Hours) is consistent across all variants, indicating equivalent handling and storage requirements.

Product Status: All parts maintain Active product status from Renesas Electronics Corporation, ensuring continued availability and manufacturer support.

Selection Basis: Component selection between R5F104FCDFP#10, R5F104FCAFP#10, and R5F104FCAFP#30 is determined by packaging and supply chain requirements rather than electrical performance. The suffix designation (#10 versus #30) reflects tape and reel configuration specifications. Inventory availability and procurement lead times are the primary factors influencing part selection among these equivalent options.

Frequently Asked Questions (FAQ)

Q: Are R5F104FCAFP#10 and R5F104FCAFP#30 direct substitutes for R5F104FCDFP#10?
