Substitute Part Grouping Explanation

Substitution eligibility for the R5F10RB8AFP#V0 is determined by strict equivalence across the following critical parameters:

Processor Architecture: RL78 core with 16-bit instruction set
Memory Configuration: Exact match of 8KB FLASH, 2KB EEPROM, and 1KB RAM
Clock Speed: 24MHz maximum operating frequency
Package Format: 32-LQFP (7x7mm) surface mount package
Electrical Ratings: Voltage supply range 1.6V ~ 5.5V and operating temperature -40°C ~ 85°C
Peripheral Set: CSI, I2C, LINbus, UART/USART connectivity; DMA, LCD, LVD, POR, PWM, WDT peripherals
I/O Count: 20 input/output pins

The substitute part R5F10RB8AFP#30 meets all these criteria, differing only in packaging format (Tray versus unspecified) and product status (Active versus Obsolete).

Engineering Selection Recommendations

The R5F10RB8AFP#30 is a direct functional equivalent to the R5F10RB8AFP#V0. Both parts share identical electrical specifications, memory architecture, peripheral configuration, and physical packaging. The primary distinction is product lifecycle status: R5F10RB8AFP#V0 is classified as obsolete, while R5F10RB8AFP#30 maintains active status with Renesas Electronics Corporation.

For new designs or production continuity, R5F10RB8AFP#30 is the appropriate selection. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings (MSL 3, 168 hours). No circuit modifications or firmware adjustments are required when transitioning between these parts.

Frequently Asked Questions (FAQ)

Q: Can R5F10RB8AFP#30 replace R5F10RB8AFP#V0 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. No PCB redesign, firmware modification, or circuit reconfiguration is necessary. Direct substitution is supported at the component level.

Q: What is the difference between R5F10RB8AFP#V0 and R5F10RB8AFP#30?

A: The parts differ only in packaging format (unspecified versus Tray) and product lifecycle status (Obsolete versus Active). All functional specifications, memory configuration, electrical ratings, and pin assignments are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, ECCN classification (EAR99), and HTSUS code (8542.31.0001). Moisture sensitivity levels and handling requirements are equivalent.

Q: What is the 32-LQFP (7x7) package specification?

A: This designates a 32-pin Low-Profile Quad Flat Package with 7mm x 7mm body dimensions. Both parts use this identical surface mount package format, ensuring footprint compatibility on PCBs designed for either part number.

Q: Are there other RL78/L12 microcontroller variants available?

A: The provided data confirms only R5F10RB8AFP#30 as a direct substitute for R5F10RB8AFP#V0. Other RL78/L12 variants may exist with different memory configurations or package formats, but they would not qualify as direct equivalents based on the specified parameters.
