R5F104FADFP#10 Equivalent & Substitute Parts

Part Overview

The R5F104FADFP#10 is a 16-bit embedded microcontroller from Renesas Electronics Corporation, part of the RL78/G14 series. This device integrates a 32MHz RL78 core processor with 16KB FLASH program memory, 4KB EEPROM, and 2.5KB RAM in a 44-LQFP surface mount package. The microcontroller operates across a wide supply voltage range of 1.6V to 5.5V and includes integrated connectivity interfaces (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LVD, POR, PWM, WDT). The product maintains Active status with full RoHS3 compliance and REACH unaffected classification. Substitute parts are identified based on identical electrical specifications, memory configurations, and package specifications to ensure direct functional replacement in embedded system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R5F104FADFP#10 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Core Processor Architecture: RL78 16-bit core at 32MHz operating frequency

Memory Configuration: 16KB FLASH program memory, 4KB EEPROM, and 2.5KB RAM

Electrical Specifications: Supply voltage range 1.6V to 5.5V, operating temperature -40°C to 85°C

Connectivity & Peripherals: CSI, I2C, LINbus, UART/USART interfaces with DMA, LVD, POR, PWM, and WDT functions

I/O Configuration: 31 I/O pins

Package Specification: 44-LQFP (10x10) surface mount package

Compliance Standards: RoHS3 compliance, REACH unaffected status, MSL 3 rating

The identified substitute parts R5F104FAAFP#10 and R5F104FAAFP#30 maintain identical electrical and functional specifications. The difference between these parts and the main part number lies in packaging format (Tray packaging for substitutes versus the main part's unspecified packaging) and manufacturing lot designations (#10 and #30 suffixes). These variations do not affect electrical performance, memory capacity, or functional capability.

Parameter Comparison

Engineering Selection Recommendations

All three microcontroller variants—R5F104FADFP#10, R5F104FAAFP#10, and R5F104FAAFP#30—are functionally equivalent for embedded system applications requiring RL78/G14 architecture. Selection between these parts is determined by availability, packaging format, and supply chain requirements rather than electrical performance differences.

Product Status Compliance: All parts maintain Active product status with Renesas Electronics Corporation, ensuring continued support and availability for production designs.

Regulatory Compliance: All variants are RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and consumer applications.

Moisture Sensitivity: All parts carry MSL 3 rating with 168-hour floor life, requiring standard moisture control procedures during storage and handling.

Packaging Considerations: The R5F104FAAFP#10 and R5F104FAAFP#30 are supplied in Tray packaging format, which may influence logistics and automated assembly processes compared to the main part number. The suffix designations (#10 and #30) indicate manufacturing lot codes and do not affect functional specifications.

Inventory Availability: Current stock levels are 1149 units for R5F104FADFP#10, 2100 units for R5F104FAAFP#10, and 2226 units for R5F104FAAFP#30, providing multiple sourcing options for production requirements.
