Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete R5F104GJDNA#U0 is determined by strict equivalence across the following critical parameters:

Core Functional Parameters:

• RL78/G14 series architecture
• 16-bit core processor
• 32MHz operating frequency
• 256KB FLASH program memory
• 24KB RAM and 8KB EEPROM
• 34 I/O pins
• Identical peripheral set (DMA, LVD, POR, PWM, WDT)
• Matching connectivity interfaces (CSI, I2C, LINbus, UART/USART)
• Equivalent data converter configuration (A/D 10x8/10b; D/A 2x8b)

Physical Parameters:

• 48-HWQFN (7x7) package
• Surface mount mounting type
• MSL 3 moisture sensitivity rating

Electrical Parameters:

• Supply voltage range compatibility
• Operating temperature range

The substitute parts maintain identical functional and physical specifications while differing in packaging format (Tray or Tape & Reel) and product status (Active vs. Obsolete). Voltage supply ranges and operating temperature ranges vary among substitutes and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

R5F104GJGNA#20 (Direct Manufacturer Substitute - Tray Packaging)

This part is classified as an active direct substitute with identical functional specifications. It maintains full compatibility with the obsolete R5F104GJDNA#U0 across all core parameters. The primary differences are product status (Active), RoHS3 compliance certification, and packaging format (Tray). The supply voltage range is restricted to 2.4V ~ 5.5V compared to the original 1.6V ~ 5.5V, and the operating temperature range extends to 105°C. Selection of this part is appropriate for applications where the higher minimum supply voltage and extended temperature range do not present constraints.

R5F104GJGNA#00 (Manufacturer Recommended Substitute - Tape & Reel Packaging)

This part represents the manufacturer-recommended alternative, offering identical functional specifications with Active product status and ROHS3 compliance. It provides the additional capability of supporting both external and internal oscillator types, compared to internal-only operation in the main part. The supply voltage range is 2.4V ~ 5.5V, and operating temperature extends to 105°C. This part is supplied in Tape & Reel format, suitable for high-volume automated assembly operations.

R5F104GJANA#20 (Parametric Equivalent - Tray Packaging)

This part maintains full functional equivalence with the original R5F104GJDNA#U0, including identical supply voltage range (1.6V ~ 5.5V) and operating temperature range (-40°C ~ 85°C). It is classified as Active with ROHS3 compliance. The primary distinction is the packaging format (Tray). This part is optimal for applications requiring the original electrical specifications while transitioning from obsolete to active inventory.

All three substitute parts are manufactured by Renesas Electronics Corporation and maintain the RL78/G14 series architecture with identical memory configurations, I/O count, and peripheral integration.

Frequently Asked Questions (FAQ)

Q: Can R5F104GJGNA#20 be used as a direct replacement for R5F104GJDNA#U0?

A: R5F104GJGNA#20 is functionally equivalent across all core parameters including processor architecture, memory configuration, I/O count, and peripheral set. However, the supply voltage minimum is 2.4V compared to 1.6V in the original part. Applications operating below 2.4V require alternative selection. The operating temperature range extends to 105°C, providing broader thermal capability.

Q: What is the difference between R5F104GJGNA#00 and R5F104GJGNA#20?

A: Both parts are functionally identical with identical electrical specifications. The primary difference is packaging format: R5F104GJGNA#00 is supplied in Tape & Reel format for automated assembly, while R5F104GJGNA#20 is supplied in Tray format. R5F104GJGNA#00 additionally supports external oscillator operation, whereas R5F104GJGNA#20 supports internal oscillator only.

Q: Why is R5F104GJANA#20 listed as a substitute if it has the same specifications as the original part?

A: R5F104GJANA#20 maintains identical electrical and functional specifications to the obsolete R5F104GJDNA#U0, including supply voltage range (1.6V ~ 5.5V) and operating temperature range (-40°C ~ 85°C). The distinction is product status: R5F104GJANA#20 is Active with ROHS3 compliance certification, whereas the original is Obsolete. This part is selected when original specifications must be preserved during transition from obsolete inventory.

Q: Are all substitute parts pin-compatible with the original R5F104GJDNA#U0?

A: All substitute parts utilize the identical 48-HWQFN (7x7) package with 34 I/O pins. Pin configuration and functionality are equivalent across all listed substitutes.

Q: What is the significance of the packaging format differences?

A: Packaging format affects procurement and assembly processes. Tape & Reel format (R5F104GJGNA#00) is optimized for high-volume automated pick-and-place assembly. Tray format (R5F104GJGNA#20 and R5F104GJANA#20) is suitable for lower-volume or manual assembly operations. Functional performance is identical regardless of packaging format.

Q: Which substitute should be selected for new designs?

A: Selection depends on specific application requirements. For applications requiring the original 1.6V minimum supply voltage, R5F104GJANA#20 is appropriate. For applications compatible with 2.4V minimum supply voltage and benefiting from extended temperature range to 105°C, R5F104GJGNA#20 or R5F104GJGNA#00 are suitable. R5F104GJGNA#00 is recommended for high-volume production due to Tape & Reel packaging and dual oscillator support.

Q: Are all substitute parts RoHS compliant?

A: All three substitute parts are ROHS3 compliant. The original R5F104GJDNA#U0 RoHS status is not specified in available documentation.
