Substitute Part Grouping Explanation

Substitution of the R5F101FGDFP#X0 with the R5F101FGDFP#50 is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications in the following key areas:

• Core processor architecture (RL78)
• Memory configuration (128KB FLASH, 12KB RAM)
• Operating frequency (32MHz)
• I/O count (31 pins)
• Supply voltage range (1.6V ~ 5.5V)
• Peripheral set (DMA, LVD, POR, PWM, WDT)
• Connectivity interfaces (CSI, I2C, LINbus, UART/USART)
• Package form factor (44-LQFP 10x10)
• Environmental specifications (Operating temperature -40°C ~ 85°C)
• Compliance certifications (ROHS3, MSL 3)

The primary distinction is product status: the original part is obsolete, while the substitute is active. Both parts are manufactured by Renesas Electronics Corporation and are functionally interchangeable at the system level.

Parameter Comparison

• Equivalent compliance certifications (ROHS3 Compliant, MSL 3)
• Active product status ensuring long-term supply chain availability
• No design modifications required for direct substitution

Both parts carry the same ECCN (3A991A2) and HTSUS (8542.31.0001) classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can R5F101FGDFP#50 be used as a direct replacement for R5F101FGDFP#X0?

A: Yes. Both parts are electrically and mechanically identical. The only difference is product status: the original is obsolete while the substitute is active. No circuit modifications or firmware changes are required.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 44-LQFP (10x10) package form factor with identical pin assignments and mechanical specifications.

Q: Do both parts have the same memory configuration?

A: Yes. Both feature 128KB FLASH program memory and 12KB RAM, with identical access specifications.

Q: Are the operating voltage ranges the same?

A: Yes. Both parts operate across the identical supply voltage range of 1.6V ~ 5.5V.

Q: What is the significance of the product status difference?

A: The substitute part is active, meaning it is currently manufactured and available through distribution channels. The original part is obsolete and subject to limited availability. For new designs or production continuity, the active substitute is the appropriate selection.

Q: Are the connectivity interfaces identical?

A: Yes. Both parts provide identical connectivity: CSI, I2C, LINbus, and UART/USART interfaces.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant with MSL 3 (168 Hours) moisture sensitivity rating.
