Substitute Part Grouping Explanation

Substitute parts for the R5F526TFADFP#10 are determined by strict equivalence across the following critical parameters:

• Series and Core Processor: All substitutes must be RX26T series with RXv3 core processor
• Memory Configuration: Program memory must be 512KB Flash, EEPROM 16K x 8, RAM 64K x 8
• Performance Specifications: Core speed must be 120MHz with 32-bit architecture
• Electrical Characteristics: Supply voltage range 2.7V ~ 5.5V
• I/O Count: 82 I/O pins
• Package: 100-LQFP (14x14mm) surface mount package
• Connectivity and Peripherals: CANbus, I2C, SCI, SPI, UART/USART, DMA, LVD, POR, PWM, WDT
• Data Converters: A/D 22x12b, D/A 2x12b
• Compliance: ROHS3 compliant, REACH unaffected

The identified substitute parts R5F526TFCDFP#30 and R5F526TFDDFP#30 meet all these criteria and are therefore direct parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three parts—R5F526TFADFP#10, R5F526TFCDFP#30, and R5F526TFDDFP#30—are active production parts from Renesas Electronics Corporation with identical electrical, functional, and mechanical specifications. Selection between these parts is based on availability and packaging designation differences reflected in the part number suffix. All parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for embedded microcontroller applications.

Frequently Asked Questions (FAQ)

Q: Are R5F526TFCDFP#30 and R5F526TFDDFP#30 direct substitutes for R5F526TFADFP#10?

A: Yes. All three parts are parametric equivalents with identical core specifications: RXv3 32-bit processor, 120MHz speed, 512KB Flash, 64KB RAM, 16KB EEPROM, 82 I/O pins, and 100-LQFP package. The differences in part number suffixes (#10, #30) indicate packaging or distribution channel variations, not functional differences.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. All three parts share the same 100-LQFP (14x14mm) package footprint, pin configuration, and electrical characteristics. No PCB redesign is required when substituting between these parts.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: RX26T series designation, RXv3 core processor, 120MHz clock speed, 512KB Flash memory, 64KB RAM, 16KB EEPROM, 82 I/O pins, 2.7V–5.5V supply voltage range, identical peripheral set (CANbus, I2C, SCI, SPI, UART/USART, DMA, LVD, POR, PWM, WDT), A/D 22x12b and D/A 2x12b converters, -40°C to 85°C operating temperature, and 100-LQFP surface mount package.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant and REACH unaffected. Compliance status is identical across all substitute options.

Q: What should be considered when selecting between these equivalent parts?

A: Selection should be based on inventory availability, lead time, and packaging designation requirements from your supply chain. From an engineering perspective, all three parts are functionally and electrically identical and will perform identically in your application.
