Substitute Part Grouping Explanation

Substitution of the R7F701403EAFB-C#KA1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part R7F701423EAFB-C#BA1 qualifies as a parametric equivalent based on the following criteria:

Electrical Equivalence Parameters:

• Identical core processor architecture (RH850G3M)
• Matching core size (32-Bit Single-Core)
• Identical operating frequency (120MHz)
• Identical program memory capacity (4MB FLASH)
• Identical EEPROM capacity (64K x 8)
• Identical RAM capacity (512K x 8)
• Identical I/O count (126 pins)
• Identical voltage supply range (2.7V ~ 5.5V)
• Identical data converter specifications (A/D 16x12b)
• Identical oscillator type (Internal)
• Identical operating temperature range (-40°C ~ 150°C)

Mechanical Equivalence Parameters:

• Identical mounting type (Surface Mount)
• Identical package designation (176-LQFP / 176-LFQFP 24x24)
• Identical connectivity and peripheral feature sets

Compliance Equivalence:

• Both parts maintain active product status
• Both parts are RoHS3 compliant
• Both parts have identical MSL rating (3, 168 Hours)
• Both parts are REACH unaffected

The primary distinction between these parts is the packaging format: the main part R7F701403EAFB-C#KA1 uses standard packaging, while the substitute R7F701423EAFB-C#BA1 is supplied in Tray packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the R7F701403EAFB-C#KA1 and R7F701423EAFB-C#BA1 are suitable for direct substitution in applications requiring RH850/D1L series microcontrollers with 4MB FLASH memory and 120MHz operation. Selection between these parts should be based on the following factors:

Product Status and Compliance: Both parts maintain active product status with Renesas Electronics Corporation, ensuring continued support and availability. Both parts are fully RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and automotive embedded applications.

Packaging Considerations: The R7F701403EAFB-C#KA1 is supplied in standard packaging, while the R7F701423EAFB-C#BA1 is supplied in Tray packaging. Selection should align with assembly line requirements and handling procedures. Tray packaging is typically preferred for automated pick-and-place operations, while standard packaging may be suitable for manual assembly or lower-volume production.

Inventory and Lead Time: The R7F701423EAFB-C#BA1 currently maintains higher inventory availability (1748 Pcs) compared to the R7F701403EAFB-C#KA1 (1010 Pcs). This may influence selection for time-sensitive procurement or high-volume production requirements.

Electrical and Mechanical Compatibility: Complete electrical and mechanical equivalence ensures drop-in replacement capability without circuit redesign or PCB layout modifications. The identical 176-LFQFP (24x24) package footprint, pin configuration, and electrical specifications guarantee functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can R7F701423EAFB-C#BA1 be used as a direct replacement for R7F701403EAFB-C#KA1 in existing designs?

A: Yes. The R7F701423EAFB-C#BA1 is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications or PCB redesign is required for substitution.

Q: What is the difference between these two part numbers?

A: The primary difference is the packaging format. The R7F701403EAFB-C#KA1 uses standard packaging, while the R7F701423EAFB-C#BA1 is supplied in Tray packaging. All electrical, mechanical, and functional specifications are identical.

Q: Are both parts suitable for automotive applications?

A: Both parts are active products from Renesas Electronics Corporation with RoHS3 compliance and identical operating temperature ranges (-40°C ~ 150°C). Suitability for specific automotive applications depends on system-level requirements and qualification procedures, which are outside the scope of component-level equivalence.

Q: What is the significance of the MSL rating for these parts?

A: Both parts have an MSL rating of 3 with a 168-hour floor life. This indicates moisture sensitivity and requires controlled storage conditions and handling procedures during assembly. The identical MSL rating ensures equivalent moisture management requirements.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are electrically and mechanically equivalent with identical package specifications, they can be used interchangeably within the same design. However, packaging format differences (standard vs. Tray) may require separate handling procedures during assembly.

Q: What connectivity options are available on both parts?

A: Both parts provide identical connectivity: CANbus, EBI/EMI, Ethernet, I2C, LINbus, SCI, SPI, SSI, UART/USART, and USB. Peripheral support includes DMA, I2S, LCD, LVD, POR, PWM, and WDT.

Q: Are there any differences in memory specifications?

A: No. Both parts feature identical memory configurations: 4MB FLASH program memory, 512KB RAM, and 64KB EEPROM. Data converter specifications (A/D 16x12b) are also identical.
