Substitute Part Grouping Explanation

Substitution of the R5F104AAASP#V0 is determined by strict equivalence across the following critical parameters:

Processor Architecture: RL78 core with 16-bit instruction set
Memory Configuration: 16KB FLASH, 4KB EEPROM, 2.5KB RAM
Operating Frequency: 32MHz maximum clock speed
Electrical Specifications: 1.6V to 5.5V supply voltage range
Peripheral Set: Identical connectivity (CSI, I2C, LINbus, UART/USART) and peripherals (DMA, LVD, POR, PWM, WDT)
Package Format: 30-LSSOP surface mount package with 0.240" width, 6.10mm pitch
Compliance Standards: ROHS3 compliance and REACH unaffected status

The substitute parts R5F104AAASP#30 and R5F104AAASP#10 maintain full electrical and mechanical compatibility with the main part number. Differences exist only in packaging configuration (tray vs. tube) and moisture sensitivity level (MSL), which do not affect functional performance or circuit integration.

Engineering Selection Recommendations

The R5F104AAASP#30 and R5F104AAASP#10 are direct functional equivalents of the obsolete R5F104AAASP#V0. Both substitute parts maintain identical electrical performance, memory configuration, and peripheral functionality. Selection between these two options should be based on packaging and supply chain requirements:

R5F104AAASP#30 is supplied in tray packaging and carries MSL 3 (168 hours) moisture sensitivity rating.

R5F104AAASP#10 is supplied in tray packaging and carries MSL 3 (168 hours) moisture sensitivity rating.

Both parts are active products with current manufacturing status, ensuring long-term availability and supply continuity. ROHS3 compliance and REACH unaffected status are maintained across all variants. The primary distinction between the main part and substitutes is product lifecycle status; the obsolete R5F104AAASP#V0 should be replaced with either active equivalent for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can R5F104AAASP#30 and R5F104AAASP#10 be used interchangeably with R5F104AAASP#V0?

A: Yes. All three part numbers are electrically and mechanically identical. They share the same RL78 processor core, 16KB FLASH memory, 4KB EEPROM, 2.5KB RAM, 32MHz clock speed, 30-LSSOP package format, and peripheral configuration. The substitutes are active products, whereas the main part is obsolete.

Q: What is the difference between the packaging configurations?

A: The R5F104AAASP#V0 is supplied in tube packaging. Both R5F104AAASP#30 and R5F104AAASP#10 are supplied in tray packaging. Packaging configuration does not affect component functionality or electrical performance; it impacts only handling, storage, and supply chain logistics.

Q: Does the MSL rating difference affect circuit performance?

A: No. Moisture Sensitivity Level (MSL) is a storage and handling specification, not a functional parameter. MSL 1 (unlimited) on the main part and MSL 3 (168 hours) on the substitutes indicate different moisture exposure tolerances during storage and assembly. Both ratings are suitable for standard manufacturing processes.

Q: Are the substitute parts suitable for new product designs?

A: Yes. R5F104AAASP#30 and R5F104AAASP#10 are active products with current manufacturing status. They are appropriate for new designs, production builds, and system maintenance. The obsolete R5F104AAASP#V0 should not be used for new designs.

Q: Do all three parts meet the same compliance standards?

A: Yes. All variants are ROHS3 compliant and REACH unaffected. Compliance certifications are identical across the main part and both substitutes.
