Substitute Part Grouping Explanation

Substitution for the R5F100FCAFP#V0 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria define valid substitutes:

Identical core processor architecture (RL78)
Identical core size (16-Bit)
Identical operating frequency (32MHz)
Identical memory configuration (32KB FLASH, 4KB EEPROM, 2KB RAM)
Identical I/O count (31 pins)
Identical package type and pinout (44-LQFP 10x10)
Identical voltage supply range (1.6V ~ 5.5V)
Identical connectivity and peripheral set (CSI, I2C, LINbus, UART/USART, DMA, LVD, POR, PWM, WDT)
Identical operating temperature range (-40°C ~ 85°C)
Identical compliance certifications (ROHS3, REACH Unaffected)

Substitute parts differ only in packaging format (tray vs. tube) or internal manufacturing revision codes (suffix designations #V0, #30, #10), which do not affect functional or electrical performance.

Engineering Selection Recommendations

R5F100FCAFP#30 and R5F100FCAFP#10 are direct functional equivalents to R5F100FCAFP#V0, differing only in packaging format and manufacturing revision. Both substitute parts carry active product status from Renesas Electronics, ensuring ongoing availability and support. Both maintain identical ROHS3 compliance and REACH unaffected status.

R5F100FCDFP#30 is a parametric equivalent with identical electrical specifications and package type. This part also carries active product status and equivalent compliance certifications.

For applications requiring the obsolete R5F100FCAFP#V0, selection among active equivalents should prioritize inventory availability and packaging requirements. All three substitute parts are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can R5F100FCAFP#30 replace R5F100FCAFP#V0 in existing designs?

A: Yes. R5F100FCAFP#30 is functionally identical to R5F100FCAFP#V0 across all electrical and mechanical parameters.
