R5F10BMGCLFB#15 Equivalent & Substitute Parts

Part Overview

The R5F10BMGCLFB#15 is a 16-bit embedded microcontroller from Renesas Electronics Corporation, part of the RL78/F13 series. This device integrates 128KB of FLASH program memory, 8KB of RAM, and 4KB of EEPROM, operating at 32MHz with a supply voltage range of 2.7V to 5.5V. The microcontroller features integrated connectivity options including CANbus, CSI, I2C, LINbus, SPI, and UART/USART interfaces, along with peripheral functions such as low-voltage detection (LVD), power-on reset (POR), pulse-width modulation (PWM), and watchdog timer (WDT). The device is housed in an 80-LFQFP surface-mount package and is qualified for automotive applications under AEC-Q100 standards.

Substitute parts become necessary when the primary part number experiences extended lead times, inventory constraints, or supply chain disruptions. Alternative part numbers within the same series and with identical electrical and mechanical specifications provide continuity for production and design implementation.

Substitute Part Grouping Explanation

Substitution of the R5F10BMGCLFB#15 is based on strict parametric equivalence within the RL78/F13 microcontroller series. The substitute part R5F10BMGCLFB#35 maintains identical electrical specifications across all critical parameters that determine functional compatibility:

Core Substitution Criteria:

The substitute part shares the same base product number (R5F10), series designation (RL78/F13), core processor architecture (RL78), and bit width (16-Bit). Both devices operate at identical clock speeds (32MHz) and feature the same memory configuration: 128KB FLASH program memory, 8KB RAM, and 4KB EEPROM. The supply voltage range (2.7V ~ 5.5V), I/O pin count (68), and data converter specifications (A/D 22x10b SAR) are identical.

Connectivity and Peripheral Equivalence:

Both the main part and substitute provide identical communication interfaces (CANbus, CSI, I2C, LINbus, SPI, UART/USART) and peripheral functions (LVD, POR, PWM, WDT). The operating temperature range (-40°C ~ 105°C) and automotive qualification (AEC-Q100) are maintained across both part numbers.

Package and Compliance Equivalence:

Both devices utilize the same 80-LFQFP (12x12) surface-mount package, ensuring mechanical and electrical pin compatibility. RoHS3 compliance, MSL rating (3), and REACH status are identical, confirming environmental and regulatory equivalence.

The difference between R5F10BMGCLFB#15 and R5F10BMGCLFB#35 reflects packaging or distribution variants (indicated by the suffix designations #15 and #35) rather than functional or electrical differences.

Parameter Comparison

Engineering Selection Recommendations

The R5F10BMGCLFB#35 is a direct parametric equivalent to the R5F10BMGCLFB#15 and is suitable for substitution in applications requiring the RL78/F13 microcontroller platform. Both devices maintain active product status with Renesas Electronics Corporation and carry identical automotive-grade qualifications under AEC-Q100 standards.

Selection between these part numbers should be based on availability and supply chain considerations. The R5F10BMGCLFB#35 currently maintains higher inventory levels (106,100 pieces) compared to the R5F10BMGCLFB#15 (3,304 pieces), making it the preferred choice for production continuity when supply constraints are a factor.

Both parts comply with ROHS3 environmental standards and maintain identical moisture sensitivity levels (MSL 3), ensuring equivalent handling and storage requirements. The identical operating temperature range (-40°C ~ 105°C) and supply voltage specifications (2.7V ~ 5.5V) confirm suitability for automotive applications across the full specified environmental envelope.

No design modifications, firmware adjustments, or PCB layout changes are required when substituting between these part numbers, as all electrical, mechanical, and functional parameters are identical.
