Key Parameters

Substitute Part Grouping Explanation

Substitution of the R5F104BGAFP is determined by strict equivalence across the following critical parameters:

• Processor Architecture: RL78 core with identical instruction set compatibility
• Memory Configuration: 128KB FLASH, 8KB EEPROM, 16KB RAM (exact match required)
• Clock Speed: 32MHz operation
• Package Type: 32-LQFP (7x7) surface mount form factor
• Electrical Specifications: 1.6V ~ 5.5V supply voltage range
• I/O Count: 22 I/O pins
• Connectivity Interfaces: CSI, I2C, LINbus, UART/USART
• Compliance: ROHS3 Compliant, REACH Unaffected

The only allowable variation between the main part and substitutes is the packaging configuration (Bulk versus Tray), which does not affect electrical or functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both R5F104BGAFP#50 and R5F104BGAFP#30 are functionally and electrically identical, with Active product status from Renesas Electronics Corporation. Selection between these parts should be based on:

• Packaging Requirements: Choose Bulk (R5F104BGAFP#50) for direct component use or Tray (R5F104BGAFP#30) for automated assembly line integration
• Inventory Availability: R5F104BGAFP#30 (Tray) currently maintains higher stock levels (2576 Pcs) compared to R5F104BGAFP#50 (Bulk, 700 Pcs)
• Compliance Verification: Both parts meet ROHS3 and REACH requirements, suitable for regulated applications
• Supply Chain Continuity: Either part provides equivalent functionality for design implementations

Frequently Asked Questions (FAQ)

Q: Can R5F104BGAFP#30 be used as a direct replacement for R5F104BGAFP#50?

A: Yes. Both parts are electrically and functionally identical. The only difference is packaging configuration (Tray versus Bulk). The microcontroller die, memory configuration, clock speed, I/O count, and all electrical specifications are identical.

Q: What does the packaging designation (#50 and #30) indicate?

A: The suffix indicates the packaging format. #50 denotes Bulk packaging, while #30 denotes Tray packaging. This affects handling and assembly processes but does not impact component performance or compatibility.

Q: Are there any pin compatibility concerns between these parts?

A: No. Both parts use the identical 32-LQFP (7x7) package with 22 I/O pins in the same configuration. PCB layouts and pin assignments are fully compatible.

Q: Do both parts support the same operating temperature range?

A: Yes. Both R5F104BGAFP#50 and R5F104BGAFP#30 operate across -40°C to 85°C (TA), making them suitable for industrial and consumer applications with identical thermal specifications.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 Compliance and REACH Unaffected status, with MSL Rating 3 (168 Hours). They are suitable for the same regulated applications and manufacturing environments.
