Substitute Part Grouping Explanation

Substitute parts for the R5F104FEDFP#50 are identified based on strict equivalence of the following critical parameters:

• Core Architecture & Speed: RL78 core processor operating at 32MHz
• Memory Configuration: 64KB FLASH program memory, 5.5KB RAM, 4KB EEPROM
• Peripheral Set: Identical connectivity (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LVD, POR, PWM, WDT)
• Electrical Specifications: Supply voltage range 1.6V ~ 5.5V, operating temperature -40°C ~ 85°C
• Package Format: 44-LQFP (10x10) surface mount package
• I/O Count: 31 I/O pins
• Data Conversion: A/D 10x8/10b

The R5F104FEAFP#50 meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is the packaging format: the R5F104FEDFP#50 is supplied in standard packaging, while the R5F104FEAFP#50 is supplied in Tape & Reel (TR) format. This difference affects only the delivery and handling method, not the electrical or functional characteristics of the device.

Parameter Comparison

Engineering Selection Recommendations

Both the R5F104FEDFP#50 and R5F104FEAFP#50 are active production devices manufactured by Renesas Electronics Corporation and carry ROHS3 compliance certification. The devices are electrically and functionally identical, with all core specifications, memory configurations, peripheral sets, and operating parameters matching exactly.

The selection between these two parts should be based on procurement and assembly requirements:

• R5F104FEDFP#50: Standard packaging format, suitable for lower-volume applications or when individual component handling is required.
• R5F104FEAFP#50: Tape & Reel (TR) packaging format, optimized for high-volume automated assembly processes and surface mount technology (SMT) production lines.

Both parts meet identical compliance requirements (ROHS3, REACH Unaffected) and carry the same moisture sensitivity level (MSL 3, 168 Hours). The choice between them does not affect system performance, reliability, or regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the R5F104FEDFP#50 and R5F104FEAFP#50 functionally identical?

A: Yes. Both devices are parametric equivalents with identical electrical specifications, memory configuration, peripheral set, operating temperature range, and supply voltage specifications. All functional characteristics are equivalent.

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

A: The primary difference is the packaging format. The R5F104FEDFP#50 uses standard packaging, while the R5F104FEAFP#50 uses Tape & Reel (TR) format. This affects only the delivery method and handling during assembly, not the device functionality or performance.

Q: Can I substitute R5F104FEAFP#50 for R5F104FEDFP#50 in my design?
