Substitute Part Grouping Explanation

Substitution eligibility for the PIC16F84T-04I/SO is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 1.75KB FLASH program memory, 64 x 8 EEPROM, 68 x 8 RAM
• Operating Frequency: 4MHz
• I/O Count: 13 pins
• Supply Voltage Range: 4V ~ 6V
• Temperature Range: -40°C ~ 85°C
• Package Format: 18-SOIC surface mount
• Peripheral Set: POR (Power-On Reset), WDT (Watchdog Timer)

The substitute part PIC16F84-04I/SO maintains identical electrical and mechanical specifications across all parameters listed above. The primary distinction is product status: the substitute transitions from obsolete to active production status, with verified programmability and improved inventory availability.
