Engineering Selection Recommendations

The R5F101FDAFP#30 is the direct functional equivalent for the obsolete R5F101FDAFP#V0. Both devices share identical electrical specifications, core architecture, memory configuration, I/O pin count, and package format. Selection between these parts should be based on the following criteria:

For New Designs and Ongoing Production: The R5F101FDAFP#30 is the appropriate choice, as it maintains Active product status with Renesas Electronics Corporation. This part carries ROHS3 and REACH compliance certifications identical to the original specification.

Packaging and Storage Considerations: The R5F101FDAFP#30 is supplied in Tray packaging with Moisture Sensitivity Level (MSL) 3, requiring storage within 168 hours of exposure to ambient conditions exceeding 30°C and 85% relative humidity. The original R5F101FDAFP#V0 carries MSL 1 (Unlimited), indicating less stringent moisture handling requirements. Procurement and storage protocols must account for this difference.

Compliance and Regulatory Status: Both parts maintain identical ROHS3 Compliant and REACH Unaffected certifications, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Are R5F101FDAFP#V0 and R5F101FDAFP#30 pin-for-pin compatible?

A: Yes. Both devices feature identical 44-LQFP (10x10) package specifications with 31 I/O pins in the same physical configuration. No PCB layout modifications are required for substitution.

Q: What is the functional difference between these two part numbers?

A: There is no functional difference. Both parts implement the RL78/G13 16-bit microcontroller architecture with identical core speed (32MHz), memory capacity (48KB FLASH, 3KB RAM), peripheral set, and connectivity protocols. The difference is product lifecycle status and packaging format.

Q: Why does the R5F101FDAFP#30 have a higher Moisture Sensitivity Level (MSL)?

A: MSL 3 (168 hours) versus MSL 1 (Unlimited) reflects different manufacturing or packaging processes. The R5F101FDAFP#30 requires adherence to moisture control protocols during storage and handling. Devices must be stored in dry conditions and used within 168 hours of exposure to environments exceeding 30°C and 85% relative humidity.

Q: Can I use R5F101FDAFP#30 in existing designs originally specified for R5F101FDAFP#V0?

A: Yes. Electrical and mechanical specifications are identical. Existing firmware, PCB layouts, and system designs require no modification. Moisture handling procedures during component storage and assembly must follow the MSL 3 specification.

Q: What is the inventory status for these parts?

A: R5F101FDAFP#V0 inventory is 2052 pieces. R5F101FDAFP#30 inventory is 2324 pieces, both listed as New
