Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R5F104PLAFB#10 are identified based on strict parametric equivalence within the RL78/G14 microcontroller family. The substitution logic is governed by the following key parameters:

Core Electrical Parameters (Must Match):

• Manufacturer: Renesas Electronics Corporation
• Series: RL78/G14
• Core Processor: RL78
• Core Size: 16-Bit
• Operating Speed: 32MHz
• Program Memory: 512KB (512K x 8) FLASH
• EEPROM Size: 8K x 8
• RAM Size: 48K x 8
• Supply Voltage: 1.6V ~ 5.5V
• Number of I/O: 82
• Connectivity: CSI, I2C, LINbus, UART/USART
• Peripherals: DMA, LVD, POR, PWM, WDT
• Data Converters: A/D 20x8/10b; D/A 2x8b
• Operating Temperature: -40°C ~ 85°C (TA)

Mechanical Parameters (Package Variations Allowed):

• Package Type: 100-LQFP (physical dimensions may vary: 14x14 or 14x20)
• Mounting Type: Surface Mount
• Packaging: Tray

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)
• REACH Status: REACH Unaffected

The identified substitute parts R5F104PLAFB#30 and R5F104PLAFA#30 maintain identical electrical specifications and compliance certifications. Variations in package dimensions (14x14 versus 14x20) represent mechanical differences that do not affect functional equivalence when PCB layout accommodates the physical footprint.

Parameter Comparison

Engineering Selection Recommendations

All three parts—R5F104PLAFB#10, R5F104PLAFB#30, and R5F104PLAFA#30—are manufactured by Renesas Electronics Corporation and maintain Active product status. Each part holds ROHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory requirements for embedded microcontroller applications.

Selection Criteria Based on Provided Parameters:

The R5F104PLAFB#10 and R5F104PLAFB#30 share identical package dimensions (100-LQFP 14x14) and are directly interchangeable at the PCB level. Both parts provide equivalent electrical performance and compliance certifications.

The R5F104PLAFA#30 features a 100-LQFP package with dimensions of 14x20, representing a different physical footprint. This part maintains full electrical equivalence but requires PCB layout accommodation for the modified package dimensions.

Selection between these parts is determined by:

1. PCB layout constraints and available footprint space
2. Inventory availability and supply chain requirements
3. Packaging format preference (Tray packaging applies to all three parts)

All three parts are suitable for applications requiring 16-bit RL78 microcontroller functionality with 512KB FLASH memory, 48KB RAM, and comprehensive peripheral integration within the specified operating temperature and voltage ranges.

Frequently Asked Questions (FAQ)

Q: Are R5F104PLAFB#10, R5F104PLAFB#30, and R5F104PLAFA#30 electrically identical?

A: Yes. All three parts share identical electrical specifications including core processor (RL78), operating speed (32MHz), memory configuration (512KB FLASH, 48KB RAM, 8KB EEPROM), I/O count (82 pins), connectivity interfaces, and peripheral features. They operate within the same voltage range (1.6V ~ 5.5V) and temperature range (-40°C ~ 85°C).

Q: What is the difference between these substitute parts?

A: The primary difference is package dimensions. R5F104PLAFB#10 and R5F104PLAFB#30 use 100-LQFP packages with 14x14mm dimensions. R5F104PLAFA#30 uses a 100-LQFP package with 14x20mm dimensions. These dimensional variations affect PCB footprint requirements but do not impact electrical functionality.

Q: Can I substitute R5F104PLAFA#30 for R5F104PLAFB#10 on an existing PCB?

A: Substitution requires PCB layout verification. The different package dimensions (14x20 versus 14x14) mean the physical footprint differs. If the PCB layout accommodates the larger 14x20 footprint, substitution is electrically and functionally valid. If the PCB is designed for the 14x14 footprint, physical placement conflicts will occur.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 3 (168 Hours) certification. Compliance certifications are identical across all substitute parts.

Q: Which part should I select for new designs?

A: Selection depends on PCB layout requirements and supply chain availability. For designs with space constraints favoring the smaller 14x14 footprint, R5F104PLAFB#10 or R5F104PLAFB#30 are appropriate. For designs with available space or existing layouts supporting the 14x20 footprint, R5F104PLAFA#30 is suitable. All three parts deliver identical embedded microcontroller functionality.

Q: Are there any performance differences between the substitute parts?

A: No. All three parts operate at 32MHz, provide identical memory capacity, feature the same peripheral set, and support the same connectivity interfaces. Performance characteristics are equivalent across all substitute parts.

Q: What is the significance of the "#10" and "#30" designations?

A: These designations indicate different packaging or tape reel configurations within the same electrical specification. The core microcontroller functionality remains identical; the suffix reflects supply chain or packaging format variations.
