Substitute Part Grouping Explanation

Substitution eligibility for the R7F7010243AFP#KA1 is determined by strict equivalence across the following critical parameters:

• Processor Core: RH850G3K (identical architecture and instruction set)
• Memory Configuration: 768KB FLASH, 32KB EEPROM, 96KB RAM (exact match required)
• Operating Frequency: 80MHz (no deviation)
• Package Type: 100-LFQFP (14x14) (identical footprint and pin count)
• Supply Voltage Range: 3V ~ 5.5V (identical operating range)
• Peripheral Set: CANbus, CSI, I2C, LINbus, SPI, UART/USART, DMA, PWM, WDT (complete match)
• I/O Count: 81 pins (exact match)
• Temperature Range: -40°C ~ 105°C (identical specification)

The R7F7010243AFE#KA2 meets all substitution criteria as an active product within the same series with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The R7F7010243AFE#KA2 is the direct equivalent substitute for the obsolete R7F7010243AFP#KA1. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical specifications, memory configuration, peripheral set, and package footprint. The primary distinction is product status: the R7F7010243AFP#KA1 is obsolete, while the R7F7010243AFE#KA2 is active with confirmed inventory availability (3200 units in stock versus 933 units for the obsolete variant).

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The R7F7010243AFE#KA2 includes REACH Unaffected status documentation, providing additional regulatory clarity for new designs. No functional or mechanical modifications are required when transitioning from the main part to the substitute.
