Substitute Part Grouping Explanation

Substitution eligibility for the Z8F0123PB005SC is determined by strict equivalence across the following critical parameters:

• Processor Architecture: eZ8 core processor
• Memory Configuration: 1KB FLASH program memory, 256 x 8 RAM
• Operating Frequency: 5MHz
• Supply Voltage Range: 2.7V ~ 3.6V
• Peripheral Set: IrDA, UART/USART connectivity; Brown-out Detect/Reset, LED, POR, PWM, WDT
• I/O Count: 6 pins
• Package Type: 8-DIP (0.300", 7.62mm)
• Data Conversion: A/D 4x10b

The Z8F0123PB005SG meets all substitution criteria as a direct equivalent, with identical electrical and mechanical specifications. The primary distinction is product status and packaging format.
