Substitute Part Grouping Explanation

Substitution eligibility for the R7F7010303AFP#KA3 is determined by strict equivalence across the following critical parameters:

Core Electrical Specifications: Identical RH850G3K processor, 32-bit single-core architecture, and 80MHz operating frequency are mandatory. Memory configuration must match exactly: 1.5MB FLASH, 32KB EEPROM, and 160KB RAM.

Package & Physical Form Factor: The 144-LFQFP (20x20) surface mount package is non-negotiable for direct PCB compatibility without layout redesign.

Voltage & Environmental Ratings: Supply voltage range (3V ~ 5.5V) and operating temperature range (-40°C ~ 105°C) must be identical or exceed the original specification.

Connectivity & Peripherals: All interface protocols (CANbus, CSI, I2C, LINbus, SPI, UART/USART) and peripheral functions (DMA, PWM, WDT) must be present and functionally equivalent.

Compliance & Certifications: RoHS3 compliance and MSL rating (3, 168 Hours) establish baseline environmental and manufacturing standards.

Parts meeting all these criteria are classified as direct substitutes. Deviations in any parameter disqualify a part from this category.
