R5F10NLEDFB#10 Equivalent & Substitute Parts

Part Overview

The R5F10NLEDFB#10 is a 16-bit RL78/I1C microcontroller manufactured by Renesas Electronics Corporation, featuring 64KB FLASH memory, 6KB RAM, and 2KB EEPROM in a 64-LFQFP (10x10) surface mount package. This device integrates multiple communication interfaces including CSI, I2C, IrDA, LINbus, and UART/USART, along with peripheral functions such as LCD driver, low voltage detection, power-on reset, PWM, and watchdog timer.

The R5F10NLEDFB#10 carries a product status designation of "Not For New Designs," indicating that Renesas has discontinued active development for this variant. Equivalent substitute parts are available with active product status, providing continued availability and support for applications requiring RL78/I1C microcontroller functionality with identical electrical and mechanical specifications.

All substitute parts listed maintain identical specifications across these parameters. Variations in product status and ECCN classification do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The R5F10NLEDFB#15, R5F10NLEDFB#35, R5F11TLEDFB#15, and R5F11TLEDFB#35 are designated as Active products by Renesas Electronics Corporation. These parts maintain full electrical and mechanical equivalence to the R5F10NLEDFB#10 and provide continued manufacturing support and availability. Selection among these active variants is based on inventory availability and supply chain requirements.

Secondary Substitutes (Not For New Designs Status):

The R5F11TLEDFB#30 carries a "Not For New Designs" designation identical to the primary part. While electrically and mechanically equivalent, this variant shares the same lifecycle status as the R5F10NLEDFB#10 and does not provide long-term availability advantages.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 3 (168 Hours) moisture sensitivity classification. The R5F10NLEDFB series variants carry ECCN classification EAR99, while R5F11TLEDFB#15 and R5F11TLEDFB#30 carry ECCN 3A991A2, and R5F11TLEDFB#35 carries ECCN EAR99. Export control classifications must be verified against current regulatory requirements for specific applications and destinations.

Recommended Selection Path:

For applications requiring long-term component availability and continued manufacturer support, R5F10NLEDFB#15, R5F10NLEDFB#35, or R5F11TLEDFB#35 are the preferred substitutes. These parts provide identical functionality with active product status from Renesas Electronics Corporation.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the R5F10NLEDFB#10?

A: Yes. All substitute parts maintain identical electrical specifications including core processor (RL78), core size (16-Bit), operating speed (24MHz), memory configuration (64KB FLASH, 6KB RAM, 2KB EEPROM), I/O count (27), voltage supply range (1.7V ~ 5.5V), connectivity interfaces (CSI, I2C, IrDA, LINbus, UART/USART), and peripheral functions (LCD, LVD, POR, PWM, WDT).

Q: What is the difference between R5F10NLEDFB and R5F11TLEDFB variants?

A: The R5F10NLEDFB and R5F11TLEDFB variants are electrically and mechanically equivalent. The primary difference is the base product number designation (R5F10 versus R5F11), which reflects internal Renesas product line organization. Both series are RL78/I1C microcontrollers with identical specifications.

Q: Can I use R5F10NLEDFB#35 as a direct replacement for R5F10NLEDFB#10?

A: Yes. The R5F10NLEDFB#35 is a direct substitute with identical electrical and mechanical specifications. The suffix designation (#35, #15, #10, #30) indicates packaging or supply chain variants and does not affect functional compatibility. Both parts use the same 64-LFQFP (10x10) package.

Q: What does the "Not For New Designs" product status mean?

A: "Not For New Designs" indicates that Renesas Electronics Corporation has discontinued active development for this specific part variant. The component remains available for existing applications but is not recommended for new product development. Active status alternatives provide continued manufacturer support and guaranteed long-term availability.

Q: Are there any differences in compliance or certifications between the substitute parts?

A: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 3 (168 Hours) moisture sensitivity classification. Export control classifications (ECCN) vary between variants: R5F10NLEDFB series carries EAR99, while R5F11TLEDFB#15 and R5F11TLEDFB#30 carry 3A991A2, and R5F11TLEDFB#35 carries EAR99. Verify applicable ECCN classifications for your specific application and destination.

Q: Is the 64-LFQFP (10x10) package identical across all substitute parts?

A: Yes. All substitute parts use the same 64-LQFP package designation with 64-LFQFP (10x10) supplier device package specification. Pin configuration, pitch, and physical dimensions are identical across all listed variants, enabling direct PCB-level substitution.

Q: Which substitute part should I select for new product development?

A: For new product development, select from parts with Active product status: R5F10NLEDFB#15, R5F10NLEDFB#35, R5F11TLEDFB#15, or R5F11TLEDFB#35. These variants provide continued manufacturer support and guaranteed availability. Selection among active variants is based on inventory availability and supply chain logistics.
