Substitute Part Grouping Explanation

Substitution of the R5F10366ASP#X0 is determined by strict equivalence across the following critical parameters:

• Processor Architecture: RL78 core, 16-bit
• Memory Configuration: 2KB FLASH program memory, 256 bytes RAM
• Operating Frequency: 24MHz
• Supply Voltage Range: 1.8V ~ 5.5V
• Connectivity Interfaces: CSI, I2C, UART/USART
• Peripheral Set: LVD, POR, PWM, WDT
• I/O Count: 14 pins
• Package Format: 20-LSSOP surface mount
• Temperature Range: -40°C ~ 85°C
• Compliance Standards: ROHS3, REACH Unaffected

The R5F10366ASP#55 meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is packaging configuration (tape and reel versus bulk) and product status (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

The R5F10366ASP#55 is a direct functional equivalent to the R5F10366ASP#X0. All electrical, mechanical, and thermal specifications are identical. The R5F10366ASP#55 carries Active product status, ensuring ongoing manufacturer support and availability, whereas the R5F10366ASP#X0 is classified as Obsolete.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The difference in packaging format (tape and reel versus bulk) does not affect electrical or mechanical compatibility and is a procurement consideration only.

For new designs or system updates, the R5F10366ASP#55 is the appropriate selection due to its Active status and continued availability. For legacy system maintenance requiring the exact original part number, the R5F10366ASP#X0 remains functionally interchangeable where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can R5F10366ASP#55 replace R5F10366ASP#X0 in existing designs?

A: Yes. The R5F10366ASP#55 is electrically and mechanically identical to the R5F10366ASP#X0. All functional parameters, pin configurations, memory specifications, and operating characteristics are equivalent. Direct substitution is supported without design modification.

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

A: The primary differences are product status and packaging format. The R5F10366ASP#X0 is Obsolete with tape and reel packaging, while the R5F10366ASP#55 is Active with bulk packaging. Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level (MSL 3, 168 Hours). Regulatory and environmental certifications are equivalent.

Q: What is the 20-LSSOP package specification?

A: The 20-LSSOP is a surface mount package measuring 0.173 inches in width with a 4.40mm body width. Both parts use this identical package format, ensuring PCB footprint compatibility.

Q: Why is the R5F10366ASP#X0 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this specific part number. The R5F10366ASP#55 represents the current Active equivalent, ensuring continued availability and manufacturer support.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C (TA). Thermal specifications and operating characteristics are equivalent.
