Substitute Part Grouping Explanation

Substitution eligibility for the R5F101LEAFB#V0 is determined by strict equivalence across the following critical parameters:

• Manufacturer & Series: Must be Renesas Electronics Corporation RL78/G13 series
• Core Architecture: 16-bit RL78 processor at 32MHz
• Memory Configuration: 64KB FLASH and 4KB RAM
• I/O Count: 48 pins minimum
• Package Type: 64-LQFP form factor
• Electrical Specifications: 1.6V ~ 5.5V supply voltage range
• Environmental Compliance: ROHS3 compliant, MSL 3 rating

The R5F101LEAFB#30 qualifies as a direct substitute based on identical electrical, functional, and mechanical specifications. The primary distinction is packaging format (Tray vs. standard packaging) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The R5F101LEAFB#30 is the direct equivalent substitute for the R5F101LEAFB#V0. Both parts share identical electrical specifications, memory configuration, I/O architecture, and compliance certifications (ROHS3, REACH Unaffected). The R5F101LEAFB#30 maintains Active product status with higher inventory availability (2514 Pcs vs. 913 Pcs), making it the preferred selection for new designs and production continuity.

The distinction between these part numbers reflects packaging format differences only. The R5F101LEAFB#30 is supplied in Tray packaging, while the R5F101LEAFB#V0 uses standard packaging. Both are surface-mount 64-LQFP devices with identical pin configurations, thermal characteristics, and functional performance.
