Parameter Comparison

Engineering Selection Recommendations

R5F10NLEDFB#35: This part is a direct parametric equivalent to the R5F10NLEDFB#15 with identical electrical and mechanical specifications. The part maintains Active product status and ROHS3 compliance. Selection of this substitute is appropriate for applications requiring the same functional performance with higher inventory availability (1482 units in stock versus 737 units for the main part).

R5F11TLEDFB#35: This part is a parametric equivalent with identical electrical and mechanical specifications to the R5F10NLEDFB#15. The part maintains Active product status and ROHS3 compliance. The base product number differs (R5F11 versus R5F10), but all functional parameters remain equivalent. This substitute is suitable for direct replacement in existing designs.

R5F11TLEDFB#30: This part is a parametric equivalent with identical electrical and mechanical specifications to the R5F10NLEDFB#15. However, this part carries a "Not For New Designs" product status designation. While functionally equivalent and ROHS3 compliant, this part is appropriate only for sustaining production of existing designs or legacy system support. The ECCN classification differs (3A991A2 versus EAR99), which may affect export compliance considerations depending on destination and application.

Frequently Asked Questions (FAQ)

Q: Can R5F10NLEDFB#35 be used as a direct replacement for R5F10NLEDFB#15?

A: Yes. R5F10NLEDFB#35 is a parametric equivalent with identical electrical specifications, memory configuration, pin count, package type, and operating characteristics. Both parts are Active status and ROHS3 compliant. The suffix difference (#35 versus #15) does not affect functional compatibility.

Q: What is the difference between R5F10NLEDFB#15 and R5F11TLEDFB#35?

A: The base product numbers differ (R5F10 versus R5F11), but all electrical and mechanical parameters are identical. Both parts feature the same 16-bit RL78 core, 24MHz speed, 64KB FLASH, 6KB RAM, 2KB EEPROM, 27 I/O pins, and 64-LFQFP package. Both maintain Active product status and ROHS3 compliance.

Q: Can R5F11TLEDFB#30 be used in new designs?

A: R5F11TLEDFB#30 carries a "Not For New Designs" product status. This part is functionally equivalent to R5F10NLEDFB#15 in all electrical and mechanical parameters but is designated for sustaining production only. For new design implementations, R5F10NLEDFB#35 or R5F11TLEDFB#35 are recommended as both maintain Active product status.

Q: Are all substitute parts housed in the same package?

A: Yes. All substitute parts use the 64-LFQFP (10x10) surface mount package with 64-LQFP case designation. Pin count, pitch, and physical dimensions are identical across all parts, ensuring direct PCB compatibility.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching core processor (RL78), core size (16-Bit), clock speed (24MHz), program memory (64KB FLASH), EEPROM (2K x 8), RAM (6K x 8), supply voltage range (1.7V ~ 5.5V), I/O count (27), connectivity options (CSI, I2C, IrDA, LINbus, UART/USART), peripheral set (LCD, LVD, POR, PWM, WDT), operating temperature range (-40°C ~ 85°C), and package type (64-LFQFP 10x10). All substitute parts maintain these specifications identically.

Q: Do the substitute parts have the same compliance certifications?

A: All substitute parts are ROHS3 compliant and REACH Unaffected. Moisture Sensitivity Level is 3 (168 Hours) for all parts. ECCN classifications differ between R5F10NLEDFB#15/R5F10NLEDFB#35/R5F11TLEDFB#35 (EAR99) and R5F11TLEDFB#30 (3A991A2), which may affect export compliance requirements based on destination and end-use application.

Q: What inventory levels are available for each substitute part?

A: R5F10NLEDFB#15 has 737 units in stock, R5F10NLEDFB#35 has 1482 units, R5F11TLEDFB#30 has 1131 units, and R5F11TLEDFB#35 has 1958 units. All parts are listed as New Original In Stock.
