R5F100PJAFB#10 Equivalent & Substitute Parts

Part Overview

The R5F100PJAFB#10 is a 16-bit embedded microcontroller from Renesas Electronics Corporation, part of the RL78/G13 series. This device integrates 256KB of FLASH program memory, 20KB of RAM, and 8KB of EEPROM, operating at 32MHz with a supply voltage range of 1.6V to 5.5V. The microcontroller features multiple connectivity options including CSI, I2C, LINbus, and UART/USART, along with integrated peripherals such as DMA, LVD, POR, PWM, and WDT. The R5F100PJAFB#10 is housed in a 100-LQFP (14x14) surface mount package and maintains Active product status with full RoHS3 compliance.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits the use of functionally identical devices with different packaging or tape-and-reel configurations.

Substitute Part Grouping Explanation

Substitution of the R5F100PJAFB#10 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Manufacturer: Renesas Electronics Corporation
• Series: RL78/G13
• Core Processor: RL78
• Core Size: 16-Bit
• Speed: 32MHz
• Program Memory Size: 256KB (256K x 8)
• Program Memory Type: FLASH
• EEPROM Size: 8K x 8
• RAM Size: 20K x 8
• Voltage Supply (Vcc/Vdd): 1.6V ~ 5.5V
• Number of I/O: 82
• Data Converters: A/D 20x8/10b
• Connectivity: CSI, I2C, LINbus, UART/USART
• Peripherals: DMA, LVD, POR, PWM, WDT
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 100-LQFP
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)
• REACH Status: REACH Unaffected

Variable Parameters (Non-Critical for Substitution):

• Supplier Device Package dimensions (14x14 vs. 14x20)
• Packaging configuration (Tray)
• Tape-and-reel suffix designation (#10, #30)

All three substitute parts maintain identical electrical and functional specifications. Differences exist only in physical package dimensions and distribution packaging formats, which do not affect circuit-level compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—R5F100PJAFA#10, R5F100PJAFA#30, and R5F100PJAFB#30—are functionally equivalent to the R5F100PJAFB#10 at the circuit and system level. Each part maintains Active product status from Renesas Electronics Corporation and carries identical RoHS3 compliance and REACH Unaffected certifications.

Selection Criteria Based on Provided Parameters:

The choice between substitute parts depends on physical package dimensions and distribution format:

• R5F100PJAFB#10 and R5F100PJAFB#30 feature 100-LQFP (14x14) package dimensions, suitable for designs with space constraints or existing PCB layouts optimized for this footprint.

• R5F100PJAFA#10 and R5F100PJAFA#30 feature 100-LQFP (14x20) package dimensions, providing alternative physical geometry for different PCB design requirements.

• The suffix designation (#10 vs. #30) indicates tape-and-reel packaging configuration and does not affect electrical performance or compatibility.

All parts operate across the identical voltage supply range (1.6V ~ 5.5V), temperature range (-40°C ~ 85°C), and maintain the same moisture sensitivity level (MSL 3, 168 Hours). Selection should be based on PCB layout requirements and available inventory of the specific package variant.

Frequently Asked Questions (FAQ)

Q: Can R5F100PJAFA#10 be used as a direct replacement for R5F100PJAFB#10?

A: R5F100PJAFA#10 is electrically and functionally equivalent to R5F100PJAFB#10. The primary difference is the package dimension: R5F100PJAFA#10 uses 100-LQFP (14x20) while R5F100PJAFB#10 uses 100-LQFP (14x14). Direct PCB substitution requires verification that the PCB footprint accommodates the 14x20 dimension.

Q: What is the difference between the #10 and #30 suffix designations?

A: The #10 and #30 suffixes indicate different tape-and-reel packaging configurations used for automated assembly. Both configurations contain identical microcontroller dies and deliver the same electrical and functional performance. Selection depends on manufacturing equipment compatibility and inventory management practices.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. R5F100PJAFB#10, R5F100PJAFA#10, R5F100PJAFA#30, and R5F100PJAFB#30 are all ROHS3 Compliant and REACH Unaffected, meeting identical environmental and regulatory standards.

Q: Do the substitute parts have the same pin count and I/O configuration?

A: Yes. All substitute parts feature 100 pins in LQFP package format with 82 I/O lines. Pin assignments and functional I/O configuration are identical across all variants.

Q: What is the moisture sensitivity level for these microcontrollers?

A: All parts carry Moisture Sensitivity Level (MSL) 3 with a 168-hour floor life rating. Handling and storage procedures must comply with IPC-A-610 standards for MSL 3 components.

Q: Can R5F100PJAFB#30 replace R5F100PJAFB#10 on an existing PCB?

A: Yes. R5F100PJAFB#30 is identical to R5F100PJAFB#10 in all electrical, functional, and physical parameters. The only difference is the tape-and-reel packaging format, which does not affect PCB-level compatibility or performance.

Q: Are there any connectivity or peripheral differences between the substitute parts?

A: No. All substitute parts provide identical connectivity options (CSI, I2C, LINbus, UART/USART) and peripheral features (DMA, LVD, POR, PWM, WDT). Functional capabilities are fully equivalent across all variants.
