R5F100SLDFB#X0 Equivalent & Substitute Parts

Part Overview

The R5F100SLDFB#X0 is a 16-bit RL78/G13 microcontroller manufactured by Renesas Electronics Corporation, featuring 512KB FLASH memory, 32KB RAM, and 8KB EEPROM. This device integrates 110 I/O pins, multiple communication interfaces (CSI, I2C, LINbus, UART/USART), and comprehensive peripheral support including DMA, PWM, and watchdog timer functionality in a 128-LFQFP package.

The R5F100SLDFB#X0 carries an obsolete product status. Equivalent substitute parts with active product status are available to ensure design continuity and supply chain reliability for applications requiring RL78/G13 microcontroller functionality.

Substitute Part Grouping Explanation

Substitute parts for the R5F100SLDFB#X0 are identified based on strict electrical and mechanical parameter equivalence within the RL78/G13 microcontroller family. The substitution criteria are:

Core Equivalence Parameters:

• Identical processor architecture (RL78 core)
• Matching memory configuration (512KB FLASH, 32KB RAM, 8KB EEPROM)
• Identical clock speed (32MHz)
• Same I/O count (110 pins)
• Identical peripheral set (CSI, I2C, LINbus, UART/USART, DMA, LVD, POR, PWM, WDT)
• Matching voltage supply range (1.6V ~ 5.5V)
• Identical operating temperature range (-40°C ~ 85°C)
• Same package footprint (128-LFQFP / 128-LQFP)

Packaging Variation: The main part (R5F100SLDFB#X0) differs from substitute parts only in packaging format. The main part uses standard packaging, while substitute parts R5F100SLDFB#50 and R5F100SLAFB#50 are supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both R5F100SLDFB#50 and R5F100SLAFB#50 are direct functional equivalents to the obsolete R5F100SLDFB#X0. Selection between substitute parts should be based on the following criteria:

Product Status: R5F100SLDFB#50 and R5F100SLAFB#50 maintain active product status with Renesas Electronics Corporation, ensuring continued availability and technical support. The original R5F100SLDFB#X0 is obsolete and should be replaced in new designs.

Compliance & Certifications: All three parts maintain ROHS3 compliance and identical MSL ratings (3, 168 Hours). Substitute parts R5F100SLDFB#50 and R5F100SLAFB#50 include REACH Unaffected status and ECCN/HTSUS classifications, providing additional regulatory documentation for international applications.

Packaging Consideration: The substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume production environments. If standard packaging is required, consult with Renesas Electronics Corporation regarding alternative packaging availability for active RL78/G13 variants.

Frequently Asked Questions (FAQ)

Q: Can R5F100SLDFB#50 or R5F100SLAFB#50 be used as direct replacements for R5F100SLDFB#X0?

A: Yes. Both substitute parts are electrically and functionally identical to the main part. They feature the same processor core, memory configuration, clock speed, I/O count, peripheral set, voltage supply range, and operating temperature range. The only difference is packaging format (Tape & Reel vs. standard packaging) and product status (Active vs. Obsolete).

Q: What is the difference between R5F100SLDFB#50 and R5F100SLAFB#50?

A: Both parts are parametric equivalents within the RL78/G13 family with identical electrical specifications and memory configurations. The difference lies in internal device variants designated by the suffix characters (SLD vs. SLA). Both are functionally equivalent for applications requiring RL78/G13 microcontroller functionality.

Q: Are there any compatibility concerns when switching from R5F100SLDFB#X0 to the substitute parts?

A: No compatibility concerns exist at the electrical or functional level. Both substitute parts maintain identical pin configurations, memory organization, peripheral interfaces, and voltage specifications. PCB layout and firmware remain unchanged. The Tape & Reel packaging format is compatible with standard automated assembly equipment.

Q: What is the MSL rating and why is it important?

A: The MSL (Moisture Sensitivity Level) rating of 3 indicates the device can be exposed to moisture for up to 168 hours before soldering. All three parts share this rating. Proper storage in dry conditions and adherence to IPC-A-610 handling procedures is required to maintain device reliability.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant, meeting the Restriction of Hazardous Substances directive requirements for lead-free manufacturing and hazardous substance restrictions.
