Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010533AFP#KA3 | Same RH850/F1KH-D8 family; 3 MB flash, 256 KB SRAM, identical pinout and peripheral set. | Higher memory capacity supports larger AUTOSAR OS stacks and complex diagnostic routines. | Select when >2 MB flash is required for multi-layer software architecture or extended logging. |
| R7F7010293AFP#KA3 | Same package and core; reduced flash (1 MB), no ICUMD crypto module, 3 CAN FD channels instead of 5. | Limited security and communication bandwidth; suitable for cost-sensitive chassis modules with lower safety scope. | Choose for non-ASIL-D applications where crypto acceleration and full CAN FD channel count are not mandatory. |
Compared with R7F7010493AFP#KA3, the R7F7010533AFP#KA3 offers higher memory headroom for AUTOSAR scalability, while the R7F7010293AFP#KA3 trades flash size, crypto capability, and CAN FD count for cost reduction-making it viable only where those features are unused.
