Substitute Part Grouping Explanation

Substitute parts for the R5F524TAADFN#30 are classified based on the following substitution criteria:

Direct Manufacturer Substitutes maintain identical electrical and functional specifications while differing only in packaging format or product status:

Same core processor (RXv2), clock speed (80MHz), and memory configuration (256KB FLASH, 16KB RAM, 8KB EEPROM)
Same I/O count (60 pins), connectivity options (I2C, SCI, SPI), and peripheral set (DMA, LVD, POR, PWM, WDT)
Same voltage supply range (2.7V ~ 5.5V) and operating temperature range (-40°C ~ 85°C)
Differences limited to package variant (80-LFQFP 12x12 vs. 80-LQFP 14x14) or product status (Active vs. Discontinued)

Parametric Equivalents share all critical electrical and functional parameters but may belong to different product series within the RX family:

Identical core specifications, memory, I/O, and peripheral functionality
Same package footprint options available
Different series designation (RX24T vs. RX200) does not affect functional compatibility for applications requiring these specifications

Engineering Selection Recommendations

For PCB Layout Compatibility (Same Footprint Required): Select R5F524TAADFN#11 or R5F524TAADFN#31 when the 80-LFQFP (12x12) package footprint is fixed in your PCB design. Both parts maintain the original package dimensions and pin configuration. R5F524TAADFN#31 remains within the RX200 series, while R5F524TAADFN#11 transitions to the RX24T series; both are functionally equivalent and currently in active production status.

For Design Flexibility (Package Variant Acceptable): R5F524TAADFF#31 provides an alternative using the 80-LQFP (14x14) package format. This part maintains RX200 series continuity and is actively produced. PCB redesign is required to accommodate the larger package footprint and modified pin spacing.

For Maximum Availability: R5F524TAADFF#11 offers the highest current inventory (2840 units) among all substitutes. This RX24T series part uses the 80-LQFP (14x14) package and is in active production status. Selection of this part requires PCB layout modification.

All substitute parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with existing manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I use R5F524TAADFF#31 as a direct replacement for R5F524TAADFN#30 without PCB modifications?

A: No. While R5F524TAADFF#31 is electrically and functionally equivalent, it uses a different package format (80-LQFP 14x14 vs. 80-LFQFP 12x12). The package dimensions and pin spacing differ, requiring PCB layout redesign. If your PCB footprint is fixed to the 80-LFQFP (12x12) format, use R5F524TAADFN#31 or R5F524TAADFN#11 instead.

Q: What is the difference between R5F524TAADFN#11 and R5F524TAADFN#31?

A: Both parts use the identical 80-LFQFP (12x12) package and share all electrical specifications. The primary difference is series designation: R5F524TAADFN#11 belongs to the RX24T series, while R5F524TAADFN#31 belongs to the RX200 series. Both are functionally equivalent and currently in active production.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (R5F524TAADFF#31, R5F524TAADFF#11, R5F524TAADFN#11, and R5F524TAADFN#31) are ROHS3 compliant with identical MSL ratings of 3 (168 Hours), matching the original R5F524TAADFN#30 specifications.

Q: Which substitute part has the best availability?

A: R5F524TAADFF#11 currently has the highest inventory at 2840 units in stock. However, this part requires PCB redesign due to its 80-LQFP (14x14) package format. For same-footprint availability, R5F524TAADFN#31 offers 1426 units with the original 80-LFQFP (12x12) package.

Q: Can I use parts from different series (RX200 vs. RX24T) interchangeably?

A: Yes, for applications requiring the specified electrical and functional parameters. R5F524TAADFF#11 (RX24T series) and R5F524TAADFN#11 (RX24T series) are parametric equivalents to the RX200 series parts. All parts share identical core processor architecture (RXv2), clock speed (80MHz), memory configuration, I/O count, and peripheral functionality. Series designation does not affect functional compatibility when specifications are identical.

Q: What packaging options are available for substitution?

A: Two package formats are available: 80-LFQFP (12x12) and 80-LQFP (14x14). The 80-LFQFP (12x12) format matches the original R5F524TAADFN#30 and is available in R5F524TAADFN#11 and R5F524TAADFN#31. The 80-LQFP (14x14) format is available in R5F524TAADFF#31 and R5F524TAADFF#11 and requires PCB redesign.
