Substitute Part Grouping Explanation

Substitution eligibility for the R7F7010343AFP#AA4 is determined by strict equivalence across the following critical parameters:

• Core processor architecture and model (RH850G3K)
• Series designation (RH850/F1L)
• Core configuration (32-Bit Single-Core)
• Operating frequency (80MHz)
• Memory configuration (1.5MB FLASH, 32KB EEPROM, 160KB RAM)
• Supply voltage range (3V ~ 5.5V)
• I/O pin count (150)
• Package type and pin count (176-LQFP)
• Operating temperature range (-40°C ~ 105°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The R7F7010343AFP-C#AA4 qualifies as a direct substitute based on identical electrical specifications, memory configuration, and package format. The primary distinction is product status: the substitute part is Active, whereas the original part is Obsolete.

Parameter Comparison

Engineering Selection Recommendations
