Substitute Part Grouping Explanation

Substitute parts for the R7F100GLK3CFB#BA0 are identified based on strict parametric equivalence within the RL78/G23 microcontroller family. The substitution logic is determined by the following critical parameters:

Core Electrical Specifications (Must Match):

• RL78 core processor architecture
• 16-bit core size
• 32MHz operating frequency
• 384KB FLASH program memory capacity
• 32KB RAM capacity
• 8KB EEPROM capacity
• 1.8V to 5.5V supply voltage range
• 54 I/O pins
• Identical peripheral feature set (CSI, I2C, LINbus, SPI, UART/USART, capacitive touch, LVD, POR, PWM, WDT)
• A/D converters: 12x10-bit, 8x12-bit
• D/A converters: 2x8-bit

Mechanical Compatibility (Package Variants Allowed):

• 64-LQFP package family
• Surface mount mounting type
• Variations in physical dimensions (10x10mm vs. 12x12mm) are permitted as both are 64-LQFP configurations

Compliance & Certification (Must Match):

• ROHS3 compliance
• Moisture Sensitivity Level 3 (168 Hours)
• Active product status

Parts meeting all electrical and compliance criteria are classified as parametric equivalents regardless of minor package footprint differences within the 64-LQFP family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—R7F100GLK3CFB#BA0, R7F100GLK3CFA#AA0, and R7F100GLK3CFB#AA0—are parametric equivalents within the RL78/G23 microcontroller family and share identical electrical specifications, memory configurations, and peripheral functionality. Selection between these parts is determined by packaging and availability considerations rather than functional differences.

R7F100GLK3CFB#BA0 (Main Part): 64-LQFP (10x10mm) package. Inventory: 1021 units. Suitable for applications with space constraints or existing PCB designs optimized for 10x10mm footprint.

R7F100GLK3CFA#AA0 (Substitute): 64-LQFP (12x12mm) package. Inventory: 1157 units. Larger footprint may be preferred in applications where thermal dissipation or mechanical robustness is prioritized. Requires PCB layout modification from the main part.

R7F100GLK3CFB#AA0 (Substitute): 64-LQFP (10x10mm) package. Inventory: 1554 units. Identical footprint to main part with highest inventory availability. Direct pin-compatible replacement with no PCB redesign required.

All parts maintain ROHS3 compliance and active product status, ensuring long-term supply continuity and regulatory compliance for industrial and embedded applications. Selection should prioritize R7F100GLK3CFB#AA0 when inventory and footprint compatibility are primary considerations.

Frequently Asked Questions (FAQ)

Q1: Can R7F100GLK3CFA#AA0 be used as a direct replacement for R7F100GLK3CFB#BA0 on an existing PCB?

A: R7F100GLK3CFA#AA0 is electrically equivalent but has a different package footprint (12x12mm vs. 10x10mm). Direct PCB replacement is not possible without layout modification. The part is suitable only for new designs or redesigned PCBs accommodating the larger footprint.

Q2: What is the difference between R7F100GLK3CFB#BA0 and R7F100GLK3CFB#AA0?

A: Both parts share identical electrical specifications, memory configuration, and 10x10mm package dimensions. The difference lies in the suffix designation (#BA0 vs. #AA0), which typically indicates manufacturing batch or packaging variant. Both are pin-compatible and functionally interchangeable on existing PCBs.

Q3: Are all three substitute parts functionally identical in terms of firmware compatibility?

A: Yes. All three parts use the same RL78 core processor, operate at 32MHz, and feature identical memory sizes (384KB FLASH, 32KB RAM, 8KB EEPROM) and peripheral configurations. Firmware compiled for one part executes identically on all three without modification.

Q4: Which substitute part should be selected for new product designs?

A: R7F100GLK3CFB#AA0 is recommended for new designs due to highest inventory availability (1554 units) and identical 10x10mm footprint to the main part, ensuring design consistency across product variants.

Q5: Do package dimension differences affect thermal performance?

A: The 12x12mm package (R7F100GLK3CFA#AA0) provides marginally larger surface area for thermal dissipation compared to the 10x10mm packages. For applications with stringent thermal requirements, the larger footprint may offer minor thermal advantages, though all parts operate within the same -40°C to 105°C temperature range.

Q6: Are there any supply voltage or operating temperature differences between the substitute parts?

A: No. All three parts operate across the identical supply voltage range (1.8V to 5.5V) and temperature range (-40°C to 105°C). Electrical operating characteristics are fully equivalent.

Q7: What does the MSL 3 (168 Hours) rating mean for component handling?

A: Moisture Sensitivity Level 3 indicates the component requires controlled storage conditions and has a floor life of 168 hours after moisture exposure. All three parts share this rating and require identical handling and storage protocols.

Q8: Are all substitute parts ROHS3 compliant?

A: Yes. All three parts—R7F100GLK3CFB#BA0, R7F100GLK3CFA#AA0, and R7F100GLK3CFB#AA0—are ROHS3 compliant and suitable for applications requiring environmental and regulatory compliance.
