Engineering Selection Recommendations

All substitute parts listed—R5F100LEAFA#10, R5F100LEAFA#30, and R5F100LEAFB#30—are functionally equivalent to the R5F100LEAFB#10 across all electrical specifications and operating parameters. Each part maintains Active product status from Renesas Electronics Corporation and carries identical ROHS3 compliance and REACH unaffected certifications.

Selection Criteria Based on Provided Parameters:

The primary differentiation among substitute parts is the supplier device package designation. The R5F100LEAFB#10 and R5F100LEAFB#30 utilize the 64-LFQFP (10x10) footprint, while R5F100LEAFA#10 and R5F100LEAFA#30 utilize the 64-LQFP (12x12) footprint. Both package types are classified as 64-LQFP case style and are electrically interchangeable.

The suffix designation (#10 or #30) indicates packaging quantity or tape/reel configuration and does not affect electrical or functional characteristics. Selection between these variants depends on inventory availability and PCB layout requirements specific to the application.

All parts are suitable for direct substitution where electrical equivalence and compliance requirements are met. No additional validation is required beyond standard component procurement procedures.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the R5F100LEAFB#10?

A: Yes. All substitute parts—R5F100LEAFA#10, R5F100LEAFA#30, and R5F100LEAFB#30—share identical electrical specifications including core processor (RL78), core size (16-Bit), operating frequency (32MHz), memory configuration (64KB FLASH, 4KB EEPROM, 4KB RAM), I/O count (48), voltage supply range (1.6V ~ 5.5V), connectivity options (CSI, I2C, LINbus, UART/USART), and peripheral features (DMA, LVD, POR, PWM, WDT).

Q: What is the difference between the 64-LFQFP (10x10) and 64-LQFP (12x12) packages?

A: The primary difference is physical footprint size. The 64-LFQFP (10x10) package has a smaller footprint (10mm x 10mm) compared to the 64-LQFP (12x12) package (12mm x 12mm). Both are surface mount packages with 64 pins and are electrically equivalent. Package selection depends on PCB layout constraints and available board space.

Q: What do the suffix designations (#10 and #30) indicate?

A: The suffix designations (#10 and #30) refer to packaging quantity or tape/reel configuration supplied by Renesas Electronics Corporation. These designations do not affect electrical performance, functionality, or compatibility. Selection is based on procurement requirements and inventory availability.

Q: Can I substitute R5F100LEAFA#10 for R5F100LEAFB#10 on an existing PCB?

A: Substitution is possible if the PCB layout accommodates the 64-LQFP (12x12) footprint. The R5F100LEAFA#10 uses a larger package (12x12) compared to the R5F100LEAFB#10 (10x10). Verify PCB pad layout and clearance requirements before substitution. Electrical functionality remains identical.

Q: Are all substitute parts ROHS3 compliant and REACH unaffected?

A: Yes. All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the compliance profile of the R5F100LEAFB#10.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the main part and substitutes, have an MSL rating of 3 with a floor life of 168 hours. This indicates standard moisture sensitivity handling requirements for surface mount components.

Q: Can I use R5F100LEAFB#30 as a direct replacement for R5F100LEAFB#10?

A: Yes. Both parts use the identical 64-LFQFP (10x10) package and share all electrical specifications. The only difference is the packaging quantity designation (#10 versus #30). Direct PCB substitution is supported without layout modifications.
