Substitute Part Grouping Explanation
Substitution of the R5F100SLAFB#V0 is determined by strict equivalence across all electrical and mechanical parameters. The substitute parts maintain identical specifications in core processor architecture, memory configuration, I/O count, connectivity interfaces, and peripheral functionality. Substitution is valid based on the following criteria:
- Identical RL78/G13 series architecture and 16-bit core processor
- Matching 512KB FLASH, 32KB RAM, and 8KB EEPROM configuration
- Identical 32MHz operating speed and voltage supply range (1.6V ~ 5.5V)
- Same 110 I/O pins with CSI, I2C, LINbus, and UART/USART connectivity
- Equivalent peripheral set: DMA, LVD, POR, PWM, WDT
- Identical 128-LQFP (14x20) surface mount package
- Matching operating temperature range (-40°C ~ 85°C)
- Equivalent compliance certifications (ROHS3, REACH Unaffected, MSL 3)
The suffix designations (#V0, #30, #10) and packaging variations (Tray) represent manufacturing lot codes and packaging configurations that do not affect functional or electrical equivalence.

Engineering Selection Recommendations
For applications currently using the R5F100SLAFB#V0, transition to an active equivalent part is necessary due to obsolete product status. All four substitute parts (R5F100SLAFB#30, R5F100SLAFB#10, R5F100SLDFB#10, R5F100SLDFB#30) maintain full electrical and mechanical compatibility with identical specifications and certifications.
Selection among active substitutes should be based on:
- Packaging configuration requirements (Tray packaging available for all substitutes)
- Current inventory availability and lead times
- Manufacturing lot code preferences (suffix designations #30 or #10)
- Supply chain logistics and supplier relationships
All substitute parts carry ROHS3 compliance, REACH Unaffected status, and equivalent MSL 3 moisture sensitivity ratings, ensuring compliance with environmental and regulatory requirements identical to the original part.
Frequently Asked Questions (FAQ)
Q: Can R5F100SLAFB#30, R5F100SLAFB#10, R5F100SLDFB#10, and R5F100SLDFB#30 be used interchangeably with R5F100SLAFB#V0?
A: Yes. All substitute parts are parametrically equivalent across electrical specifications, memory configuration, I/O count, connectivity interfaces, and peripheral functionality. The suffix designations and packaging variations do not affect functional compatibility.
Q: What do the suffix codes (#V0, #30, #10) represent?
A: The suffix codes represent manufacturing lot designations and packaging configurations. They do not indicate functional or electrical differences between parts. All variants maintain identical core specifications.
Q: Is the 128-LQFP package identical across all parts?
A: Yes. All parts use the 128-LQFP (14x20) surface mount package with identical pin configuration, pitch, and mechanical dimensions.
Q: Are there any compliance or certification differences between the main part and substitutes?
A: No. All parts carry identical ROHS3 compliance, REACH Unaffected status, MSL 3 rating, and equivalent ECCN and HTSUS classifications.
Q: Why is the R5F100SLAFB#V0 listed as obsolete?
A: Obsolete status indicates the part is no longer in active production. Active equivalent alternatives are available with identical specifications and superior availability.
