Substitute Part Grouping Explanation

Substitution of the R5F104GGDNA#U0 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Core Processor: RL78
• Core Size: 16-Bit
• Speed: 32MHz
• Program Memory Size: 128KB (128K x 8)
• Program Memory Type: FLASH
• EEPROM Size: 8K x 8
• RAM Size: 16K x 8
• Number of I/O: 34
• Connectivity: CSI, I2C, LINbus, UART/USART
• Peripherals: DMA, LVD, POR, PWM, WDT
• Data Converters: A/D 10x8/10b; D/A 2x8b
• Mounting Type: Surface Mount
• Package / Case: 48-WFQFN Exposed Pad
• Supplier Device Package: 48-HWQFN (7x7)
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Allowable Variation Parameters:

• Voltage - Supply (Vcc/Vdd): Substitutes must support the original 1.6V ~ 5.5V range or a subset thereof
• Operating Temperature: Substitutes must support the original -40°C ~ 85°C range or an extended range
• Packaging Format: Tray or Tape & Reel acceptable
• Product Status: Active substitutes preferred over obsolete
• Compliance Certifications: RoHS3 compliance and REACH unaffected status preferred

All three identified substitutes maintain complete functional and electrical equivalence to the main part while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

R5F104GGGNA#20 (Direct Manufacturer Substitute)

This part is classified as a direct manufacturer substitute with active product status. It maintains complete functional equivalence across all core parameters. The voltage supply range is narrower (2.4V ~ 5.5V versus 1.6V ~ 5.5V), which is acceptable for applications not requiring ultra-low voltage operation. The extended operating temperature range (-40°C ~ 105°C) provides enhanced thermal margin. RoHS3 compliance and REACH unaffected status satisfy modern regulatory requirements. Packaging in Tray format is suitable for standard manufacturing processes.

R5F104GGGNA#00 (Manufacturer Recommended Substitute)

This part carries manufacturer recommendation status and active product status. It provides identical functional equivalence with the same voltage and temperature limitations as R5F104GGGNA#20. The oscillator type specification includes both external and internal options, providing additional design flexibility. Tape & Reel packaging format is optimized for high-volume automated assembly. RoHS3 compliance and REACH unaffected status are confirmed.

R5F104GGANA#20 (Parametric Equivalent)

This part is classified as a parametric equivalent with active product status. It maintains the original voltage supply range (1.6V ~ 5.5V) and operating temperature range (-40°C ~ 85°C), providing direct parameter matching to the obsolete main part. RoHS3 compliance and REACH unaffected status are confirmed. Tray packaging format is standard for component distribution.

All three substitutes are manufactured by Renesas Electronics Corporation and maintain identical electrical and mechanical specifications within the allowable variation parameters. Selection among these alternatives should be based on specific application voltage requirements, thermal operating conditions, and packaging format preferences for manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can R5F104GGGNA#20 replace R5F104GGDNA#U0 in applications requiring 1.6V operation?

A: No. R5F104GGGNA#20 has a minimum supply voltage of 2.4V, which does not support 1.6V operation. For applications requiring the full 1.6V ~ 5.5V range, use R5F104GGANA#20 instead.

Q: What is the difference between R5F104GGGNA#00 and R5F104GGGNA#20?

A: Both parts are electrically and functionally identical. The primary difference is packaging format: R5F104GGGNA#00 is supplied in Tape & Reel format optimized for automated assembly, while R5F104GGGNA#20 is supplied in Tray format. Both have identical voltage (2.4V ~ 5.5V) and temperature (-40°C ~ 105°C) specifications.

Q: Does R5F104GGANA#20 offer any advantages over the other substitutes?

A: R5F104GGANA#20 maintains the original voltage supply range (1.6V ~ 5.5V) and operating temperature range (-40°C ~ 85°C) of the obsolete R5F104GGDNA#U0. This makes it the direct parameter equivalent. However, R5F104GGGNA#20 and R5F104GGGNA#00 offer extended temperature operation (-40°C ~ 105°C), which may be beneficial for industrial applications.

Q: Are all three substitutes pin-compatible with the original part?

A: Yes. All three substitutes use the identical 48-HWQFN (7x7) package with 48-WFQFN Exposed Pad configuration. Pin-to-pin compatibility is confirmed across all parts.

Q: What is the significance of RoHS3 compliance on the substitute parts?

A: RoHS3 compliance indicates that the substitute parts meet Restriction of Hazardous Substances regulations, restricting the use of specific hazardous materials. This is a regulatory requirement for many markets and applications. The original obsolete part does not specify RoHS status, while all three substitutes confirm RoHS3 compliance.

Q: Can I use these substitutes interchangeably in production?

A: Yes, within the constraints of your application's voltage and temperature requirements. If your design operates within 2.4V ~ 5.5V and -40°C ~ 105°C, all three substitutes are interchangeable. If your design requires 1.6V operation or operates only to 85°C, use R5F104GGANA#20. Verify packaging format compatibility with your manufacturing assembly process.

Q: Why is the original R5F104GGDNA#U0 classified as obsolete?

A: The original part is classified as obsolete by Renesas Electronics Corporation. The three active substitutes provide equivalent or superior functionality with modern compliance certifications and extended product availability. Migration to an active substitute is recommended for new designs and ongoing production.

Q: What is the Moisture Sensitivity Level (MSL) rating, and is it the same across all parts?

A: MSL 3 (168 Hours) indicates the component can be exposed to moisture for up to 168 hours at specified humidity and temperature conditions before soldering. All four parts, including the original and all three substitutes, share identical MSL 3 rating, confirming equivalent moisture handling requirements.
