Substitute Part Grouping Explanation

Substitute parts for the R5F104AEASP#X0 are identified based on strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Core Electrical Parameters (Must Match):

• RL78/G14 series microcontroller architecture
• 16-bit core processor
• 32MHz operating speed
• 64KB FLASH program memory
• 4K x 8 EEPROM
• 5.5K x 8 RAM
• 1.6V ~ 5.5V supply voltage range
• A/D 8x8/10b data converter configuration
• 21 I/O pins
• Identical connectivity: CSI, I2C, LINbus, UART/USART
• Identical peripherals: DMA, LVD, POR, PWM, WDT

Mechanical Parameters (Must Match):

• 30-LSSOP surface mount package
• 0.240" width, 6.10mm package dimensions

Compliance Parameters (Must Match):

• ROHS3 compliance
• MSL 3 (168 Hours) moisture sensitivity
• ECCN 3A991A2
• HTSUS 8542.31.0001

Variations in packaging format (tube vs. tape & reel) and product status (obsolete vs. active) do not affect functional or electrical equivalence.

Engineering Selection Recommendations

R5F104AEASP#50 (Direct Substitute - Recommended for New Procurement)

This part is the primary substitute for the obsolete R5F104AEASP#X0. It maintains complete electrical and mechanical equivalence while offering active product status from Renesas Electronics Corporation. The only difference is packaging format (Tape & Reel vs. tube), which does not affect functional performance or circuit compatibility. This part is suitable for immediate replacement in production environments.

R5F104AEDSP#50 (Parametric Equivalent - Alternative Option)

This part provides complete parametric equivalence to the main part across all electrical specifications and operating characteristics. It maintains active product status and ROHS3 compliance. The packaging format remains tube-based, matching the original part's delivery method. This part serves as an alternative when tape & reel packaging is not required.

Both substitute parts carry identical compliance certifications (ROHS3, MSL 3, ECCN 3A991A2, HTSUS 8542.31.0001) and are suitable for direct replacement in applications originally designed for the R5F104AEASP#X0.

Frequently Asked Questions (FAQ)

Q: Can R5F104AEASP#50 be used as a direct replacement for R5F104AEASP#X0?

A: Yes. R5F104AEASP#50 is electrically and mechanically equivalent to R5F104AEASP#X0. The only difference is packaging format (Tape & Reel vs. tube). Both parts are identical in electrical performance, pin configuration, memory specifications, and operating characteristics.

Q: What is the difference between R5F104AEASP#50 and R5F104AEDSP#50?

A: Both parts are parametrically equivalent with identical electrical specifications. The difference lies in the part number suffix: AEASP vs. AEDSP. Both maintain 30-LSSOP packaging, 64KB FLASH memory, and all connectivity features. R5F104AEASP#50 is supplied in Tape & Reel format, while R5F104AEDSP#50 is supplied in tube format.

Q: Are there any pin configuration differences between these parts?

A: No. All three parts use the 30-LSSOP package with identical pin assignments, I/O configuration (21 pins), and electrical characteristics. They are pin-for-pin compatible.

Q: Do these substitute parts require any circuit modifications?

A: No circuit modifications are required. All substitute parts maintain identical voltage supply ranges (1.6V ~ 5.5V), operating temperature ranges (-40°C ~ 85°C), and peripheral configurations (DMA, LVD, POR, PWM, WDT).

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates ongoing manufacturing and support from Renesas Electronics Corporation. This ensures long-term availability, consistent quality, and continued technical support. Obsolete parts may face supply constraints and limited manufacturer support.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All parts carry MSL 3 (168 Hours) rating, indicating identical moisture handling and storage requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All three parts are functionally equivalent and can be used interchangeably without design modifications. Packaging format selection (Tape & Reel vs. tube) depends on assembly process requirements, not functional compatibility.
