Key Parameters

Substitute Part Grouping Explanation

Substitution of the R5F11TLGDFB#30 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitution:

Critical Substitution Parameters:

• Core processor architecture (RL78)
• Core size (16-Bit)
• Operating speed (24MHz)
• Program memory capacity and type (128KB FLASH)
• EEPROM capacity (2K x 8)
• RAM capacity (8K x 8)
• Number of I/O pins (27)
• Supply voltage range (1.7V ~ 5.5V)
• Data converter specifications (A/D 4x10/24b Sigma-Delta)
• Connectivity interfaces (CSI, I2C, IrDA, LINbus, UART/USART)
• Peripheral set (LCD, LVD, POR, PWM, WDT)
• Package type (64-LFQFP 10x10)
• Mounting type (Surface Mount)
• Operating temperature range (-40°C ~ 85°C)
• Compliance certifications (ROHS3, MSL 3)

All identified substitute parts maintain identical specifications across these parameters. Variations in product status, ECCN classification, and inventory levels do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The R5F11TLGDFB#30 is designated "Not For New Designs" by Renesas Electronics, indicating end-of-life status for this specific variant. All four substitute parts listed—R5F11TLGDFB#15, R5F11TLGDFB#35, R5F10NLGDFB#15, and R5F10NLGDFB#35—carry "Active" product status and are suitable for new design implementations.

From a compliance perspective, all substitute parts maintain ROHS3 compliance and MSL 3 (168 Hours) ratings, ensuring equivalent environmental and moisture handling requirements. The R5F11TLGDFB#15 and R5F11TLGDFB#35 variants retain the same ECCN classification (3A991A2) as the original part, while R5F10NLGDFB#15 and R5F10NLGDFB#35 are classified as EAR99. This distinction may affect export compliance requirements depending on destination jurisdiction.

All substitute parts are electrically and mechanically identical to the R5F11TLGDFB#30, supporting direct replacement in existing PCB designs without layout modifications or firmware changes. Selection among the four substitutes should be based on availability, supply chain considerations, and export compliance requirements specific to the application's geographic deployment.

Frequently Asked Questions (FAQ)

Q: Can R5F11TLGDFB#15, R5F11TLGDFB#35, R5F10NLGDFB#15, or R5F10NLGDFB#35 be used as direct replacements for R5F11TLGDFB#30?

A: Yes. All four substitute parts are electrically and mechanically equivalent to the R5F11TLGDFB#30. They share identical core processor architecture, memory configuration, I/O count, operating speed, supply voltage range, peripheral set, and package specifications. Direct PCB substitution is supported without design modifications.

Q: What is the difference between the R5F11 and R5F10 base product numbers?

A: The base product number designates the product line within the RL78/I1C series. Both R5F11 and R5F10 variants maintain identical electrical and mechanical specifications for the parameters listed in this reference. The difference is reflected in ECCN classification: R5F11 variants are classified as 3A991A2, while R5F10 variants are classified as EAR99.

Q: Are there differences in the suffix designations (#30, #15, #35)?

A: The suffix designations represent packaging or distribution variants within the same electrical specification. All variants maintain identical core functionality, memory capacity, operating characteristics, and pin configuration. Selection among suffix variants should be based on availability and supply chain requirements.

Q: Is the 64-LFQFP package compatible with standard PCB assembly processes?

A: Yes. The 64-LFQFP (10x10) package is a standard surface-mount package compatible with conventional reflow soldering and automated assembly equipment. All substitute parts use the identical package type and footprint.

Q: What are the compliance and certification implications of selecting substitute parts?

A: All substitute parts maintain ROHS3 compliance and MSL 3 (168 Hours) ratings. Export control classification differs between R5F11 variants (ECCN 3A991A2) and R5F10 variants (ECCN EAR99).
