Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R5F64175DFD#UB is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Core processor architecture (R32C/100)
• Core size (16/32-Bit)
• Operating speed (50MHz)
• Program memory capacity (384KB FLASH)
• RAM capacity (40KB)
• EEPROM capacity (8KB)
• I/O pin count (120)
• Supply voltage range (3V ~ 5.5V)
• Package type and dimensions (144-LQFP 20x20mm)
• Operating temperature range (-40°C ~ 85°C)
• Connectivity interfaces (CANbus, EBI/EMI, I2C, IEBus, UART/USART)
• Peripheral features (DMA, LVD, PWM, WDT)
• Data converter specifications (A/D 34x10b, D/A 2x8b)

Substitute parts are grouped into two categories: manufacturer-recommended direct substitutes (differing only in packaging designation or product status) and parametric equivalents (same electrical and functional specifications but from different series variants).

Parameter Comparison

Engineering Selection Recommendations

R5F64175DFD#2B is the manufacturer-recommended direct substitute for R5F64175DFD#UB. Both parts share identical electrical specifications and functional capabilities within the M16C/R32C/100/117 series. The primary distinction is product status: R5F64175DFD#2B is active and currently available, whereas R5F64175DFD#UB is obsolete. This substitute is preferred for new designs and ongoing production requiring component continuity.

R5F64175DFD#20 is a parametric equivalent within the same M16C/R32C/100/117 series, offering identical core functionality and electrical characteristics. This part is active and available. Selection between R5F64175DFD#2B and R5F64175DFD#20 depends on packaging designation requirements and supplier availability, as both provide equivalent performance.

R5F64185DFD#2B and R5F64185PFD#2B are parametric equivalents from the M16C/R32C/100/118 series variant. These parts maintain all critical electrical and functional parameters identical to the main part, including core processor, memory configuration, I/O count, connectivity, and peripherals. The base product number differs (R5F64185 versus R5F64175), indicating a series variant classification. Both are active and available. Selection of these parts requires confirmation that the series variant designation does not impact application-specific firmware or hardware integration requirements.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can R5F64175DFD#2B be used as a direct replacement for R5F64175DFD#UB?

A: Yes. R5F64175DFD#2B is the manufacturer-recommended substitute with identical electrical specifications, memory configuration, I/O count, connectivity interfaces, and peripheral features.
