Substitute Part Grouping Explanation

Substitution for the PIC16LC620AT-04I/SO is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 896B OTP program memory, 96 x 8 RAM
• Operating Frequency: 4MHz
• I/O Count: 13 pins
• Supply Voltage Range: 2.5V ~ 5.5V
• Package: 18-SOIC form factor
• Thermal Range: -40°C to 85°C

The identified substitute, PIC16LC620A-04I/SO, maintains identical specifications across all electrical and mechanical parameters. The primary distinction is product status: the original part is obsolete, while the substitute is active, providing continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC620A-04I/SO is the direct functional equivalent for the obsolete PIC16LC620AT-04I/SO. Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The substitute part maintains identical electrical performance, memory configuration, and thermal operating range, ensuring drop-in compatibility in existing circuit designs.

Selection of the active substitute is justified by product lifecycle considerations: the original part's obsolete status creates supply chain risk and limits long-term availability. The PIC16LC620A-04I/SO provides equivalent functionality with assured manufacturing support and continued inventory availability.
