Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The R5F104FEAFP#30 is a direct parametric equivalent to the R5F104FEAFP#10. Both devices share identical electrical specifications, memory configurations, peripheral sets, and package specifications. The difference between these part numbers reflects packaging or distribution variants from Renesas Electronics Corporation.

Selection Criteria:

Both parts maintain Active product status, ensuring continued availability and manufacturer support. Both carry ROHS3 compliance certification and REACH Unaffected status, meeting environmental and regulatory requirements for industrial and commercial applications.

The identical 44-LQFP (10x10) surface mount package, MSL 3 moisture sensitivity rating, and all electrical parameters ensure that either part can be used as a direct replacement in existing PCB designs without modification to layout, routing, or component footprints.

Selection between R5F104FEAFP#10 and R5F104FEAFP#30 should be based on inventory availability, lead time, and supply chain considerations rather than technical performance differences.
