Substitute Part Grouping Explanation

Substitute parts for the R5F100FEAFP#X0 are identified based on strict electrical and mechanical parameter matching within the RL78/G13 microcontroller family. Substitution eligibility is determined by the following criteria:

• Identical core processor architecture (RL78)
• Matching core size (16-Bit)
• Identical clock speed (32MHz)
• Identical program memory capacity (64KB FLASH)
• Identical EEPROM size (4K x 8)
• Identical RAM size (4K x 8)
• Identical voltage supply range (1.6V ~ 5.5V)
• Identical data converter specifications (A/D 10x8/10b)
• Identical I/O count (31)
• Identical connectivity interfaces (CSI, I2C, LINbus, UART/USART)
• Identical peripheral set (DMA, LVD, POR, PWM, WDT)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package type (44-LQFP 10x10)
• Identical compliance certifications (ROHS3, REACH Unaffected)

Substitutes are grouped into two categories: direct manufacturer equivalents (differing only in packaging configuration) and parametric equivalents (identical electrical and mechanical specifications with potential internal variant differences).

Parameter Comparison

Engineering Selection Recommendations

The R5F100FEAFP#X0 is classified as obsolete. Both substitute parts—R5F100FEAFP#50 and R5F100FEDFP#50—are active products with identical electrical and mechanical specifications. Selection between substitutes should be based on the following factors:

R5F100FEAFP#50 is a direct manufacturer equivalent differing only in packaging configuration (Cut Tape and Digi-Reel). This part maintains the same part number prefix and offers significantly higher inventory availability (105,100 units in stock).

R5F100FEDFP#50 is a parametric equivalent with identical functional specifications. The part number variant (FED vs. FEA) indicates an internal design variant. Inventory availability is lower (960 units in stock).

Both substitutes maintain full compliance with ROHS3 and REACH requirements. Both are rated for identical operating temperature ranges (-40°C to 85°C) and moisture sensitivity levels (MSL 3, 168 hours). Selection should prioritize R5F100FEAFP#50 for applications requiring immediate availability and standard packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can R5F100FEAFP#50 be used as a direct replacement for R5F100FEAFP#X0?

A: Yes. R5F100FEAFP#50 is a direct manufacturer equivalent with identical electrical and mechanical specifications. The difference is packaging configuration (Cut Tape/Digi-Reel vs. standard packaging). Both parts are pin-compatible, functionally equivalent, and suitable for identical applications.

Q: What is the difference between R5F100FEAFP#50 and R5F100FEDFP#50?

A: Both parts are parametric equivalents with identical electrical specifications, memory configuration, I/O count, and package type. The part number variant (FEA vs. FED) indicates an internal design variant. Functional compatibility is maintained for all specified parameters.

Q: Are the substitute parts compatible with existing PCB designs for R5F100FEAFP#X0?

A: Yes. Both substitute parts use the identical 44-LQFP (10x10) package with surface mount configuration. Pin assignments, electrical characteristics, and operating parameters are identical, ensuring full PCB compatibility without design modifications.

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

A: The obsolete status of R5F100FEAFP#X0 indicates discontinued manufacturing. The active status of both substitutes (R5F100FEAFP#50 and R5F100FEDFP#50) confirms ongoing production and long-term availability, supporting design continuity and supply chain reliability.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts maintain identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity levels (MSL 3, 168 hours). Compliance certifications are equivalent across all variants.

Q: Which substitute should be selected for new designs?

A: R5F100FEAFP#50 is recommended for new designs due to higher inventory availability and standard packaging configuration. Both parts are functionally equivalent; selection should be based on supply chain requirements and packaging preferences.
