Substitute Part Grouping Explanation

Substitution of the R7F100GLF2DFB#HA0 is determined by strict equivalence across core functional and electrical parameters. The substitute part R7F100GLF2DFA#HA0 qualifies as a parametric equivalent based on the following criteria:

Identical Core Parameters:

• Manufacturer: Renesas Electronics Corporation
• Series: RL78/G23
• Core Processor: RL78 (16-Bit)
• Operating Speed: 32MHz
• Program Memory: 96KB FLASH (96K x 8)
• EEPROM: 8K x 8
• RAM: 12K x 8
• Supply Voltage Range: 1.6V ~ 5.5V
• Number of I/O: 54
• Connectivity Interfaces: CSI, I2C, LINbus, SPI, UART/USART
• Peripheral Set: Capacitive Touch, LVD, POR, PWM, WDT
• Data Converters: A/D 12x10b, 8x12b; D/A 2x8b
• Oscillator Type: Internal
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Permitted Variation:

• Package Form Factor: 64-LQFP (10x10) versus 64-LQFP (12x12)

Both parts share identical electrical functionality and pin configuration within the 64-LQFP package family. The dimensional difference in package size (10x10mm versus 12x12mm) represents a physical form factor variation that does not affect electrical performance or functional compatibility when PCB layout accommodates the larger footprint.

Parameter Comparison

Engineering Selection Recommendations

The R7F100GLF2DFA#HA0 serves as a direct parametric equivalent to the R7F100GLF2DFB#HA0 for applications where the package form factor change from 64-LFQFP (10x10mm) to 64-LQFP (12x12mm) is accommodated by PCB layout design. Both parts maintain identical electrical specifications, functional capabilities, and compliance certifications.

Selection Criteria:

1. Functional Compatibility: Both parts deliver identical core processor architecture, memory configuration, peripheral integration, and communication interface support. No firmware or software modifications are required for functional substitution.

2. Compliance and Certification: Both parts carry ROHS3 compliance and identical moisture sensitivity ratings (MSL 3, 168 Hours), ensuring equivalent environmental and regulatory compliance for manufacturing and field deployment.

3. Product Status: Both parts maintain active production status with Renesas Electronics Corporation, ensuring long-term availability and supply chain stability.

4. Physical Integration: The substitute part requires PCB layout accommodation for the larger 12x12mm package footprint compared to the original 10x10mm footprint. Pin configuration and electrical characteristics remain unchanged, permitting direct functional substitution when physical space permits.

5. Inventory Availability: Selection between these parts may be driven by supply chain availability, with the R7F100GLF2DFA#HA0 currently showing higher inventory levels (1757 pcs) compared to the R7F100GLF2DFB#HA0 (951 pcs).

Frequently Asked Questions (FAQ)

Q1: Are the R7F100GLF2DFB#HA0 and R7F100GLF2DFA#HA0 electrically identical?

A: Yes. Both parts are electrically identical with respect to all functional parameters including processor architecture, memory capacity, operating speed, supply voltage range, I/O count, connectivity interfaces, and peripheral functionality. The only difference is the physical package form factor.

Q2: What is the difference between the 64-LFQFP (10x10) and 64-LQFP (12x12) packages?

A: Both are 64-pin LQFP packages with identical pin configuration and electrical characteristics. The primary difference is physical dimensions: the 10x10mm package is more compact, while the 12x12mm package is larger. Pin pitch and electrical performance are equivalent. PCB layout must accommodate the larger footprint of the 12x12mm variant.

Q3: Can I substitute R7F100GLF2DFA#HA0 for R7F100GLF2DFB#HA0 without firmware changes?

A: Yes. No firmware or software modifications are required. The substitute part provides identical processor instruction set, memory organization, and peripheral interface specifications. Existing firmware compiled for the original part operates without modification on the substitute part.

Q4: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status and moisture sensitivity level (MSL 3, 168 Hours). Regulatory and environmental compliance certifications are equivalent.

Q5: What factors should determine which part to select?

A: Selection should be based on: (1) PCB layout capability to accommodate the package form factor, (2) current supply chain availability, and (3) inventory levels. When PCB design permits the larger 12x12mm footprint, the R7F100GLF2DFA#HA0 may be selected based on superior availability.

Q6: Is the operating temperature range identical for both parts?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C (TA), ensuring equivalent thermal performance characteristics.
