Substitute Part Grouping Explanation

Substitution eligibility for the R7F7010303AFP#AA4 is determined by strict equivalence across the following critical parameters:

Core Substitution Criteria:

• Identical RH850G3K core processor and RH850/F1L series designation
• Matching 32-bit single-core architecture and 80MHz clock speed
• Identical program memory capacity of 1.5MB FLASH
• Matching EEPROM (32K x 8) and RAM (160K x 8) configurations
• Identical voltage supply range (3V ~ 5.5V)
• Identical I/O count (120 pins)
• Matching data converter specifications (A/D 24x10b, 24x12b)
• Identical operating temperature range (-40°C ~ 105°C)
• Identical package specification (144-LQFP / 144-LFQFP 20x20)
• Surface mount mounting type consistency

Connectivity and Peripheral Compatibility:

• All substitute parts maintain CANbus, CSI, I2C, LINbus, SPI, and UART/USART connectivity
• Peripheral variations (additional I2S, LCD, LVD, POR support) do not disqualify substitution as these represent functional enhancements

Compliance and Certification:

• ROHS3 compliance maintained across all substitute parts
• MSL rating of 3 (168 Hours) consistent
• REACH unaffected status maintained

Parameter Comparison

Engineering Selection Recommendations

R7F7010303AFP-C#AA4 (Direct Substitute)

This part is classified as a direct manufacturer substitute with active product status. It maintains identical electrical and mechanical specifications to the main part across all critical parameters. The R7F7010303AFP-C#AA4 includes additional peripheral support (I2S, LCD, LVD, POR) that does not conflict with existing designs. ROHS3 compliance and MSL rating are maintained. This part is recommended as the primary replacement for obsolete inventory management and new production applications.

R7F7010303AFE#KA4 (Parametric Equivalent)

This part meets all parametric equivalence criteria with identical core processor, memory configuration, I/O count, voltage supply range, and operating temperature specifications. The R7F7010303AFE#KA4 maintains the same peripheral set as the main part (DMA, PWM, WDT) and is classified as active product status. ROHS3 compliance and MSL rating are consistent. This part is suitable for applications where the specific part number variant is not a design constraint.

Both substitute parts are ROHS3 compliant and maintain REACH unaffected status, ensuring regulatory compliance for industrial and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can R7F7010303AFP-C#AA4 be used as a direct replacement for R7F7010303AFP#AA4?

A: Yes. The R7F7010303AFP-C#AA4 is a direct manufacturer substitute with identical core processor (RH850G3K), memory configuration (1.5MB FLASH, 32K EEPROM, 160K RAM), I/O count (120), voltage supply range (3V ~ 5.5V), operating temperature range (-40°C ~ 105°C), and 144-LQFP package specification. The additional peripherals (I2S, LCD, LVD, POR) represent functional enhancements that do not affect compatibility.

Q: What is the difference between a direct substitute and a parametric equivalent?

A: A direct substitute (R7F7010303AFP-C#AA4) is designated by the manufacturer as an alternative part number with identical specifications. A parametric equivalent (R7F7010303AFE#KA4) meets all critical electrical and mechanical parameters but uses a different part number variant. Both are functionally interchangeable within the design constraints of this product category.

Q: Are all substitute parts available in the same package?

A: Yes. All parts listed—R7F7010303AFP#AA4, R7F7010303AFP-C#AA4, and R7F7010303AFE#KA4—use identical 144-LQFP / 144-LFQFP (20x20) surface mount packaging. PCB layout and footprint compatibility are maintained across all substitutes.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, carry MSL rating 3 (168 Hours), and maintain REACH unaffected status. Regulatory compliance is consistent across the main part and all substitutes.

Q: Why is the main part R7F7010303AFP#AA4 classified as obsolete?

A: The R7F7010303AFP#AA4 is marked as obsolete by Renesas Electronics Corporation. The substitute parts R7F7010303AFP-C#AA4 and R7F7010303AFE#KA4 are active products and are recommended for new designs and production continuity.

Q: Can I use R7F7010303AFE#KA4 if my design specifically requires R7F7010303AFP-C#AA4?

A: Both parts meet identical parametric specifications for core processor, memory, I/O, voltage, temperature, and package. Selection between them depends on design-specific requirements regarding part number designation and peripheral feature utilization. Consult design documentation to determine if the part number variant is a constraint.
