Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R5F101AEASP#V0 is determined by strict equivalence across the following critical parameters:

• Core processor architecture (RL78)
• Core size (16-Bit)
• Operating frequency (32MHz)
• Program memory capacity (64KB FLASH)
• Package type and pinout (30-LSSOP)
• Voltage supply range (1.6V ~ 5.5V)
• Connectivity interfaces (CSI, I2C, LINbus, UART/USART)
• Peripheral feature set (DMA, LVD, POR, PWM, WDT)
• Operating temperature range (-40°C ~ 85°C)

The substitute part R5F101AEASP#30 maintains electrical and functional equivalence across all critical parameters. Differences in packaging format (tray vs. tube), product status (active vs. obsolete), RAM configuration (2K x 8 vs. 4K x 8), and moisture sensitivity level represent non-functional variations that do not affect core microcontroller operation or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

The R5F101AEASP#30 is the direct substitute for the obsolete R5F101AEASP#V0. Both parts are manufactured by Renesas Electronics Corporation and maintain identical electrical specifications, pin configuration, and functional capabilities within the RL78/G13 microcontroller family.

The R5F101AEASP#30 carries active product status, ensuring ongoing manufacturer support and component availability. Both variants comply with ROHS3 and REACH standards, meeting current environmental and regulatory requirements.

The RAM capacity difference (4K x 8 versus 2K x 8) represents the primary technical distinction. Applications requiring the full 4KB RAM capacity of the original part should evaluate whether the reduced 2KB RAM in the substitute meets firmware requirements. The difference in moisture sensitivity level (MSL 1 versus MSL 3) reflects packaging and storage condition variations that do not affect electrical performance or long-term reliability in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Are R5F101AEASP#V0 and R5F101AEASP#30 pin-compatible?

A: Yes. Both parts use the 30-LSSOP package with identical pinout and electrical specifications. Direct board-level substitution is possible without circuit modification.

Q: What is the significance of the RAM size difference between these parts?

A: The R5F101AEASP#V0 provides 4KB RAM while the R5F101AEASP#30 provides 2KB RAM. Firmware designed for the original part must be evaluated to confirm operation within the reduced memory constraint of the substitute. Applications with minimal RAM requirements will function identically on both variants.

Q: Why does the R5F101AEASP#30 have a higher moisture sensitivity level?

A: MSL rating reflects packaging and storage conditions rather than device performance. MSL 3 (168 hours) requires controlled humidity storage and handling procedures. Standard industrial storage and handling practices accommodate this specification without affecting field reliability.

Q: Can the R5F101AEASP#30 replace the R5F101AEASP#V0 in production designs?

A: Yes. The substitute part maintains full electrical and functional equivalence. The active product status of R5F101AEASP#30 provides superior long-term availability and manufacturer support compared to the obsolete original part.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both R5F101AEASP#V0 and R5F101AEASP#30 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
