Substitute Part Grouping Explanation

Substitution for the PIC16C72-10E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: 8-bit PIC processor with identical instruction set
• Memory Configuration: 4.6KB OTP program memory and 128 bytes RAM
• Speed Rating: 10MHz operation
• I/O Count: 22 I/O pins
• Package: 28-SSOP surface mount form factor
• Voltage Range: 4V to 6V supply compatibility
• Peripheral Set: I2C, SPI connectivity with PWM, WDT, and brown-out detection

The substitute part PIC16C72-10I/SS maintains identical electrical and functional specifications with the exception of operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C72-10I/SS serves as the direct substitute for the obsolete PIC16C72-10E/SS. Both parts maintain identical core functionality, memory architecture, and electrical specifications. The primary distinction is the operating temperature range: the substitute part is rated to -40°C ~ 85°C versus the original -40°C ~ 125°C specification.

Selection of PIC16C72-10I/SS is appropriate for applications where the reduced upper temperature limit of 85°C is compatible with system thermal requirements. The substitute part carries active product status from Microchip Technology, ensuring ongoing availability and support. Both variants maintain ROHS3 compliance and identical moisture sensitivity ratings, confirming environmental and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can PIC16C72-10I/SS replace PIC16C72-10E/SS in all applications?

A: Substitution is valid when the application's maximum operating temperature does not exceed 85°C. The PIC16C72-10I/SS is rated to 85°C, while the original part supports 125°C. Verify your system's thermal environment before selection.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 28-SSOP package with identical dimensions of 0.209" width and 5.30mm pitch. PCB footprints and mounting requirements are identical.

Q: What is the difference between the part number suffixes -10E and -10I?

A: The suffix indicates the temperature grade and packaging configuration. The -E variant supports extended temperature range (-40°C to 125°C), while the -I variant operates within industrial temperature range (-40°C to 85°C). Both maintain 10MHz speed rating.

Q: Are memory specifications identical?

A: Yes. Both parts feature 4.6KB OTP program memory, 128 bytes of RAM, and identical peripheral configurations including I2C, SPI, PWM, watchdog timer, and brown-out detection.

Q: What is the compliance status of both parts?

A: Both PIC16C72-10E/SS and PIC16C72-10I/SS are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Regulatory and environmental compliance is equivalent.
