Engineering Selection Recommendations

Direct Substitutes (RL78/G13 Series): R5F100LEDFB#30, R5F100LEAFB#10, R5F100LEAFB#30, and R5F100LEAFA#10, R5F100LEAFA#30 are functionally equivalent to the R5F100LEDFB#V0. All maintain identical electrical specifications, memory configuration, and peripheral functionality. These parts carry Active product status and are ROHS3 compliant with REACH Unaffected certification, providing superior supply chain availability compared to the obsolete main part.

Package Considerations: Parts designated with 64-LFQFP (10x10) package maintain identical physical footprint compatibility with the original R5F100LEDFB#V0. Parts designated with 64-LQFP (12x12) package require PCB layout modification due to different pin pitch and body dimensions.

Cross-Series Substitutes (RL78/F12 Series): R5F109LECJFB#10 and R5F109LECJFB#30 represent parametric equivalents from the RL78/F12 series. These parts maintain all electrical and functional parameters but belong to a different microcontroller series. Selection of cross-series substitutes requires design validation to confirm compatibility with application-specific firmware and peripheral requirements.

Compliance & Certifications: All substitute parts maintain ROHS3 compliance and MSL 3 (168 Hours) moisture sensitivity rating. Active-status parts provide superior long-term availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can R5F100LEAFB#10 directly replace R5F100LEDFB#V0 in existing designs? A: Yes. R5F100LEAFB#10 maintains identical electrical specifications, memory configuration, I/O count, and 64-LFQFP (10x10) package footprint. The part is Active status with ROHS3 compliance and REACH Unaffected certification.

Q: What is the difference between 64-LFQFP (10x10) and 64-LQFP (12x12) packages? A: These packages differ in physical dimensions and pin pitch. The 64-LFQFP (10x10) maintains the original footprint of R5F100LEDFB#V0. The 64-LQFP (12x12) requires PCB layout redesign. Both packages are electrically equivalent.

Q: Are RL78/F12 series parts (R5F109LECJFB) suitable replacements? A: R5F109LECJFB#10 and R5F109LECJFB#30 match all electrical and functional parameters. However, they belong to a different microcontroller series. Design validation is required to confirm firmware and peripheral compatibility before implementation.

Q: What does the suffix (#V0, #30, #10) indicate? A: The suffix denotes packaging and tape/reel configuration. These variations do not affect electrical performance or functional compatibility.

Q: Why is R5F100LEDFB#V0 classified as Obsolete? A: Obsolete status indicates the part is no longer in active production. Active-status equivalents ensure continued availability and supply chain support for new designs and production runs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected certification, meeting current environmental and regulatory requirements.
