Substitute Part Grouping Explanation

Substitution of the R5F101LEDFA#V0 with the R5F101LEDFA#30 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 (64KB FLASH, 4KB RAM)
• I/O count (48 pins)
• Operating frequency (32MHz)
• Supply voltage range (1.6V ~ 5.5V)
• Temperature operating range (-40°C ~ 85°C)
• Package type and dimensions (64-LQFP 12x12)
• Connectivity interfaces (CSI, I2C, LINbus, UART/USART)
• Peripheral set (DMA, LVD, POR, PWM, WDT)
• Data converter specifications (A/D 12x8/10b)
• Moisture sensitivity level (MSL 3)
• RoHS3 compliance

The primary distinction is product status: the original part is obsolete, while the substitute maintains active status with current manufacturing and availability.

Parameter Comparison

Engineering Selection Recommendations

The R5F101LEDFA#30 is the direct functional equivalent for the obsolete R5F101LEDFA#V0. Selection of the active substitute is justified by:

• Identical electrical specifications across all functional parameters
• Matching mechanical package specifications (64-LQFP 12x12)
• Equivalent RoHS3 compliance certification
• Equivalent MSL rating (3, 168 Hours)
• Active product status ensuring continued availability and manufacturing support
• No design modifications required for PCB layout or firmware implementation

The substitute part is suitable for direct replacement in existing designs, new production runs, and maintenance applications where the original part is no longer available.

Frequently Asked Questions (FAQ)
