Key Parameters

Substitute Part Grouping Explanation

Substitution for the PIC16LC620T-04I/SO is determined by strict equivalence across the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating frequency (4MHz)
• Program memory capacity and type (896B OTP)
• RAM capacity (80 x 8)
• I/O pin count (13)
• Supply voltage range (2.5V ~ 6V)
• Operating temperature range (-40°C ~ 85°C)
• Package type and dimensions (18-SOIC)
• Peripheral feature set (Brown-out Detect/Reset, POR, WDT)

The substitute part PIC16LC620-04I/SO meets all these criteria and maintains full functional and electrical compatibility. The primary distinction is product status: the main part is obsolete, while the substitute is active, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC620-04I/SO is the direct substitute for the obsolete PIC16LC620T-04I/SO. Both parts are manufactured by Microchip Technology and share identical electrical, functional, and mechanical specifications. The substitute part carries active product status, ensuring ongoing manufacturing support, availability, and compliance with current regulatory requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory standards for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, suitable for standard storage and handling conditions.

Selection of the PIC16LC620-04I/SO is appropriate for new designs, production continuity, and replacement applications where the obsolete PIC16LC620T-04I/SO was previously specified.

Frequently Asked Questions (FAQ)
