Substitute Part Grouping Explanation

Substitution of the PIC16C72T-10E/SS is determined by strict equivalence across the following critical parameters:

• Core Processor & Architecture: PIC processor family
• Core Size & Memory Configuration: 8-Bit core with 4.6KB (2K x 14) OTP program memory and 128 x 8 RAM
• Operating Speed: 10MHz clock frequency
• Voltage Supply Range: 4V ~ 6V operation
• Peripheral Set: Identical I/O count (22), connectivity (I2C, SPI), and integrated functions (PWM, WDT, brown-out detection, POR)
• Data Conversion: A/D converter with 5 channels, 8-bit resolution
• Package & Pinout: 28-SSOP surface mount package with matching physical dimensions
• Compliance & Certifications: ROHS3 compliance and MSL rating

The substitute part PIC16C72-10I/SS maintains full electrical and mechanical compatibility with the main part across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C72-10I/SS is a direct substitute for the PIC16C72T-10E/SS based on electrical and mechanical parameter equivalence. The substitute part carries Active product status, ensuring ongoing availability and supply chain support compared to the Obsolete main part.

A single operational difference exists: the substitute part specifies an operating temperature range of -40°C to 85°C, compared to the main part's -40°C to 125°C range. This narrower temperature specification should be evaluated against application requirements. For applications requiring operation above 85°C, the main part's extended temperature range may be necessary.

Both parts maintain ROHS3 compliance and identical MSL ratings, supporting equivalent environmental and regulatory requirements. The substitute part is verified as programmable through DiGi-Electronics, confirming production readiness and functional validation.

Frequently Asked Questions (FAQ)

Q: What determines if PIC16C72-10I/SS can replace PIC16C72T-10E/SS?

A: Substitution is valid when all electrical parameters (processor architecture, memory configuration, speed, voltage supply, peripherals, I/O count, and data converters) and mechanical parameters (package type, pinout, physical dimensions) are identical. The PIC16C72-10I/SS meets these criteria across all specified parameters.

Q: Does the operating temperature difference affect substitution?

A: The substitute part operates from -40°C to 85°C, while the main part operates to 125°C. For applications requiring sustained operation above 85°C, the main part's extended temperature range is necessary. For applications within the 85°C limit, the substitute part is fully compatible.

Q: Are the 28-SSOP packages physically identical?

A: Both parts use 28-SSOP surface mount packages with identical physical dimensions (0.209" width, 5.30mm). PCB footprints and assembly processes are directly compatible.

Q: What is the significance of Active versus Obsolete product status?

A: The substitute part's Active status indicates ongoing production and supply availability. The main part's Obsolete status indicates discontinued production. Transitioning to the Active substitute part ensures long-term supply chain continuity.

Q: Are compliance certifications equivalent?

A: Both parts carry ROHS3 compliance and MSL 1 (Unlimited) ratings, meeting identical environmental and regulatory requirements for manufacturing and deployment.
