Substitute Part Grouping Explanation

Substitution of the PIC16C62A-20E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: 8-bit PIC processor with identical instruction set compatibility
• Memory Configuration: 4.6KB OTP program memory and 128 x 8 RAM
• Operating Frequency: 20MHz clock speed
• I/O Count: 22 input/output pins
• Supply Voltage Range: 4V to 6V operation
• Package Format: 28-SSOP surface mount package with identical pinout
• Peripheral Set: Identical integration of PWM, watchdog timer, brown-out detection, and power-on reset

The identified substitute part PIC16C62A-20I/SS maintains full compatibility across all electrical and mechanical parameters. The primary distinction between the main part and its substitute relates to operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C62A-20I/SS serves as a direct functional equivalent to the PIC16C62A-20E/SS. Both devices are ROHS3 compliant and carry identical MSL ratings, ensuring compatibility with modern manufacturing and environmental standards.

The primary consideration for selection is the operating temperature specification. The main part supports -40°C to 125°C operation, while the substitute operates within -40°C to 85°C. Applications requiring the extended upper temperature range of 125°C must retain the original PIC16C62A-20E/SS specification. For applications operating within the -40°C to 85°C window, the PIC16C62A-20I/SS is electrically and mechanically interchangeable.

The substitute part carries active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete main part designation.

Frequently Asked Questions (FAQ)

Q: Are the PIC16C62A-20E/SS and PIC16C62A-20I/SS pin-compatible?

A: Yes. Both devices use the 28-SSOP package with identical pinout, dimensions (0.209" × 5.30mm width), and I/O configuration (22 pins). Direct PCB substitution is possible without layout modification.

Q: What is the difference between the -20E and -20I designations?

A: The suffix designates the operating temperature range. The -20E variant supports -40°C to 125°C operation, while the -20I variant operates from -40°C to 85°C. Both maintain identical electrical performance within their respective temperature ranges.

Q: Can I use the PIC16C62A-20I/SS in an application originally designed for the PIC16C62A-20E/SS?

A: Substitution is valid only if your application operates within the -40°C to 85°C temperature range. If your design requires operation above 85°C, the original PIC16C62A-20E/SS specification must be maintained.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, MSL-1 ratings, and REACH unaffected status. Compliance documentation is equivalent for both devices.

Q: Why is the main part listed as obsolete?

A: Microchip Technology has discontinued the PIC16C62A-20E/SS from active production. The PIC16C62A-20I/SS remains in active status, providing a path for design continuity and supply chain management.

Q: Are memory specifications identical between these parts?

A: Yes. Both devices feature 4.6KB OTP program memory (2K × 14 organization) and 128 × 8 bytes of RAM. Code compatibility is maintained across both parts.
