Substitute Part Grouping Explanation
Substitution of the SPC5646BCF0VLU8R is determined by strict equivalence across all electrical and mechanical parameters. The substitute part SPC5646BCF0VLU1R maintains identical specifications across the following critical parameters:
- Core processor architecture (e200z4d)
- Memory configuration (3MB FLASH, 64K EEPROM, 192K RAM)
- Operating frequency (120MHz)
- Supply voltage range (3V ~ 5.5V)
- I/O count (147 pins)
- Connectivity interfaces (CANbus, I2C, LINbus, SCI, SPI)
- Peripheral feature set (DMA, POR, PWM, WDT)
- Data converter specifications (A/D 27x10b, 5x12b)
- Package form factor (176-LQFP 24x24)
- Temperature operating range (-40°C ~ 105°C)
- Compliance certifications (ROHS3, REACH Unaffected)
The difference between these parts lies in packaging tape configuration and inventory source, not functional or electrical characteristics.
