Substitute Part Grouping Explanation

Substitute parts for the R5F104ACGSP#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 Architecture & Performance: The substitute part must utilize the same RL78 core processor architecture, maintain 16-bit core size, and operate at 32MHz processing speed.

Memory Configuration: Program memory must be 32KB FLASH (32K x 8), EEPROM must be 4K x 8, and RAM must be 4K x 8. Any deviation in memory size or type disqualifies a part from substitution.

Electrical Specifications: Supply voltage range must be 2.4V to 5.5V, and operating temperature range must be -40°C to 105°C.

Peripheral & Interface Set: The substitute must include identical connectivity interfaces (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LVD, POR, PWM, WDT). The analog-to-digital converter specification must be A/D 8x8/10b with 21 I/O pins.

Package & Physical Specifications: The package must be 30-LSSOP with 0.240" width (6.10mm), surface mount configuration, and identical moisture sensitivity level of 3 (168 Hours).

Compliance & Status: The substitute part must maintain active product status, ROHS3 compliance, and identical REACH and ECCN classifications.
