Renesas Electronics R5F100JLDFA#V0 RL78/G13 Microcontroller Equivalent & Substitute Parts

Part Overview

The R5F100JLDFA#V0 is a 16-bit RL78/G13 microcontroller manufactured by Renesas Electronics Corporation, featuring 512KB FLASH memory, 32KB RAM, and 8KB EEPROM in a 52-LQFP package. This device is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and production continuity. Direct substitutes are available from the same RL78/G13 product line with identical electrical and mechanical specifications but different packaging configurations and active product status.

Substitute Part Grouping Explanation

Substitution of the R5F100JLDFA#V0 is determined by strict equivalence across the following critical parameters:

• Core Architecture & Performance: RL78 core processor, 16-bit, 32MHz operation
• Memory Configuration: 512KB FLASH, 32KB RAM, 8KB EEPROM
• Electrical Specifications: 1.6V ~ 5.5V supply voltage range, identical I/O count (38), matching data converter specifications
• Peripheral Set: Identical connectivity (CSI, I2C, LINbus, UART/USART) and peripheral features (DMA, LVD, POR, PWM, WDT)
• Package & Thermal: 52-LQFP (10x10) surface mount package, -40°C ~ 85°C operating range
• Compliance: ROHS3 compliance and MSL 3 rating

The substitute parts R5F100JLDFA#30, R5F100JLAFA#10, and R5F100JLAFA#30 meet all these criteria. Differences exist only in packaging configuration (tray vs. tube) and product status (active vs. obsolete), which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Priority: R5F100JLDFA#30 is the primary substitute for R5F100JLDFA#V0. Both share identical part number prefixes and differ only in packaging configuration (tray packaging vs. tube packaging) and product status. This part maintains active manufacturing status with Renesas Electronics, ensuring long-term availability and supply chain continuity.

Secondary Substitutes: R5F100JLAFA#10 and R5F100JLAFA#30 are parametric equivalents with identical electrical and mechanical specifications. The suffix variation (JLAFA vs. JLDFA) indicates packaging differences only. Both parts carry active product status and ROHS3 compliance certification.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and identical MSL 3 ratings, ensuring compatibility with standard manufacturing and storage protocols. REACH compliance is documented for R5F100JLDFA#30, R5F100JLAFA#10, and R5F100JLAFA#30, providing regulatory assurance for applications subject to REACH requirements.

Inventory Availability: R5F100JLAFA#30 offers the highest current inventory (1526 units), followed by R5F100JLAFA#10 (999 units) and R5F100JLDFA#30 (909 units), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can R5F100JLDFA#30 be used as a direct replacement for R5F100JLDFA#V0?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging configuration and product status. R5F100JLDFA#30 is actively manufactured, while R5F100JLDFA#V0 is obsolete. No design modifications are required for substitution.

Q: What is the difference between R5F100JLDFA and R5F100JLAFA variants?

A: The suffix variation indicates packaging configuration only. Both variants contain identical RL78/G13 microcontroller cores with 512KB FLASH, 32KB RAM, and 8KB EEPROM. Electrical performance and pin configuration are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. R5F100JLDFA#30, R5F100JLAFA#10, and R5F100JLAFA#30 all carry ROHS3 compliance certification. The original R5F100JLDFA#V0 is also ROHS3 compliant.

Q: What does the "#V0", "#30", and "#10" suffix indicate?

A: These suffixes denote packaging configuration and tape/reel specifications. They do not affect electrical specifications, memory configuration, or performance characteristics. Selection should be based on procurement and assembly requirements.

Q: Is REACH compliance documentation available for all substitutes?

A: REACH compliance is documented for R5F100JLDFA#30, R5F100JLAFA#10, and R5F100JLAFA#30. The original R5F100JLDFA#V0 does not have documented REACH status due to its obsolete classification.

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

A: Yes. All substitute parts use the identical 52-LQFP (10x10) package with 38 I/O pins in the same configuration. No PCB layout modifications are required for substitution.

Q: What is the MSL rating and why does it matter?

A: All parts carry MSL 3 rating with 168-hour floor life. This specifies moisture sensitivity and storage requirements. Parts must be stored in controlled humidity environments and baked before reflow soldering if floor life is exceeded.
