Substitute Part Grouping Explanation

Substitute parts for the R5F564MLDDFB#V1 are identified based on parametric equivalence within the RX600 microcontroller family. The substitution criteria are strictly limited to the following electrical and mechanical parameters:

Core processor architecture (RXv2)
Operating frequency (120MHz)
Program memory capacity (4MB FLASH)
EEPROM and RAM configuration (64K x 8 and 552K x 8 respectively)
I/O pin count (111)
Supply voltage range (2.7V ~ 3.6V)
Package type and pin configuration (144-LQFP, 20x20mm)
Operating temperature range (-40°C ~ 85°C)
Connectivity feature set (CANbus, EBI/EMI, Ethernet, I2C, LINbus, MMC/SD, SCI, SPI, SSI, UART/USART, USB)
Peripheral support (DMA, LVD, POR, PWM, WDT)

The identified substitutes R5F564MLCDFB#31 and R5F564MLHDFB#31 maintain identical electrical specifications and package configuration. The primary distinction is product status: the main part is obsolete while substitutes are active, and packaging format differs (tube versus tray).

Engineering Selection Recommendations

Both R5F564MLCDFB#31 and R5F564MLHDFB#31 are direct parametric equivalents to the R5F564MLDDFB#V1. Selection between these active alternatives should be based on procurement requirements and packaging format preferences. Both parts maintain identical electrical and functional specifications, ROHS3 compliance, and MSL rating.

The transition from the obsolete R5F564MLDDFB#V1 to either active substitute ensures continued design support and supply chain availability. Packaging format (tray) differs from the original tube configuration, which may affect handling and storage procedures but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are R5F564MLCDFB#31 and R5F564MLHDFB#31 pin-for-pin compatible with R5F564MLDDFB#V1?

A: Yes. All three parts share identical 144-LQFP package configuration with 20x20mm dimensions and 111 I/O pins. Pin assignments and electrical characteristics are equivalent.

Q: What is the difference between the substitute parts?

A: R5F564MLCDFB#31 and R5F564MLHDFB#31 are parametrically identical. The distinction lies in packaging format: both are supplied in tray configuration, whereas the original part was supplied in tube format. This affects only handling and storage logistics, not electrical performance.

Q: Can I use these substitutes in existing designs without modification?

A: Yes. The substitute parts maintain identical electrical specifications, memory configuration, connectivity features, and peripheral support. No design modifications are required for functional equivalence.

Q: Why is the original part marked as obsolete?

A: Product status reflects Renesas Electronics Corporation's lifecycle management. The active substitutes provide continued access to equivalent RX600 microcontroller functionality.

Q: Are there any compliance or certification differences?

A: No. All three parts maintain ROHS3 compliance, identical MSL rating of 3 (168 Hours), and equivalent REACH and ECCN classifications.

Q: What is the inventory status of the substitute parts?

A: R5F564MLCDFB#31 has 861 pieces in stock. R5F564MLHDFB#31 has 840 pieces in stock. Both are available as new original components.
