R5F10NPJDFB#10 Equivalent & Substitute Parts

Part Overview

The R5F10NPJDFB#10 is a 16-bit embedded microcontroller from Renesas Electronics Corporation, part of the RL78/I1C series. This device integrates 256KB of FLASH program memory, 16KB of RAM, and 2KB of EEPROM within a 100-LFQFP surface mount package. The microcontroller operates at 24MHz and supports multiple communication interfaces including CSI, I2C, IrDA, LINbus, and UART/USART, with integrated peripherals for LCD control, low voltage detection, power-on reset, PWM, and watchdog timer functions.

The R5F10NPJDFB#10 carries a product status of "Not For New Designs," indicating that Renesas has transitioned this part to end-of-life status. For new development projects, equivalent substitute parts with active product status are available within the same RL78/I1C series, offering identical electrical and mechanical specifications while maintaining full design compatibility.

Substitute Part Grouping Explanation

Substitute parts for the R5F10NPJDFB#10 are determined by strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Core Electrical Parameters:

• Identical 16-bit RL78 core processor architecture
• Matching 24MHz operating frequency
• Identical 256KB FLASH program memory capacity
• Identical 16KB RAM and 2KB EEPROM configuration
• Identical supply voltage range (1.7V ~ 5.5V)
• Identical data converter specifications (A/D 6x10b, 4x24b Sigma-Delta)

Connectivity & Peripherals:

• Identical communication interfaces (CSI, I2C, IrDA, LINbus, UART/USART)
• Identical peripheral set (LCD, LVD, POR, PWM, WDT)
• Identical I/O count (60 pins)

Mechanical & Environmental Parameters:

• Identical 100-LFQFP (14x14) package configuration
• Identical surface mount mounting type
• Identical operating temperature range (-40°C ~ 85°C)
• Identical RoHS3 compliance and REACH status
• Identical Moisture Sensitivity Level (MSL 3, 168 Hours)

The substitute parts R5F10NPJDFB#15 and R5F10NPJDFB#35 differ only in packaging tape configuration (indicated by the suffix designation), not in functional or electrical specifications. Both substitutes maintain active product status with Renesas Electronics Corporation.

Parameter Comparison

Engineering Selection Recommendations

The R5F10NPJDFB#10 is designated as "Not For New Designs" by Renesas Electronics Corporation. For new product development, R5F10NPJDFB#15 or R5F10NPJDFB#35 are the recommended selections, as both maintain active product status with full long-term availability and support.

Both substitute parts provide complete electrical and functional equivalence to the R5F10NPJDFB#10. The differences between the three part numbers are limited to packaging tape configuration, which affects supply chain logistics and automated assembly processes but does not alter device functionality, performance, or electrical characteristics.

For existing designs currently using R5F10NPJDFB#10, direct substitution with either R5F10NPJDFB#15 or R5F10NPJDFB#35 requires no circuit modifications, firmware changes, or PCB layout adjustments. The 100-LFQFP package footprint, pinout, and electrical specifications remain identical across all three variants.

Both substitute parts maintain identical compliance certifications: ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 3 (168 Hours). Supply voltage requirements, operating temperature range, and all peripheral functionality are preserved.
