Substitute Part Grouping Explanation

Substitution of the PIC16C72T-04E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor with identical instruction set compatibility
• Memory Configuration: 4.6KB OTP program memory and 128 bytes RAM
• I/O Count: 22 I/O pins
• Operating Voltage: 4V ~ 6V supply range
• Clock Speed: 4MHz operation
• Peripheral Set: Identical brown-out detect/reset, POR, PWM, and WDT functionality
• Package Format: 28-SSOP surface mount package with matching pinout
• Connectivity Protocols: I2C and SPI support
• Data Conversion: 5-channel 8-bit A/D converter

The substitute part PIC16C72-04I/SS maintains full compatibility across all specified electrical and mechanical parameters, with the primary distinction being the operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C72-04I/SS serves as a direct functional substitute for the PIC16C72T-04E/SS across all core electrical and mechanical specifications. Both devices are ROHS3 compliant and carry unlimited moisture sensitivity ratings, ensuring equivalent environmental performance.

The primary distinction is the operating temperature range: the main part supports -40°C to 125°C, while the substitute operates from -40°C to 85°C. Applications requiring operation above 85°C must retain the original PIC16C72T-04E/SS specification.

The substitute part carries Active product status, providing ongoing availability and manufacturing support compared to the Obsolete classification of the main part. This makes PIC16C72-04I/SS the preferred selection for new designs and production continuity where temperature requirements do not exceed 85°C.

Frequently Asked Questions (FAQ)

Q: Can PIC16C72-04I/SS replace PIC16C72T-04E/SS in all applications?

A: The PIC16C72-04I/SS is functionally equivalent across all electrical and mechanical parameters. However, applications requiring operation above 85°C ambient temperature must use the original PIC16C72T-04E/SS, which is rated to 125°C.

Q: Are the pinouts identical between these parts?

A: Yes. Both devices use the 28-SSOP package with identical pinout, I/O configuration, and peripheral mapping. Direct PCB substitution is possible without layout modifications.

Q: What is the difference between the part number suffixes?

A: The suffix designations (T-04E/SS versus -04I/SS) indicate temperature grade and packaging variations. The T-grade supports extended temperature operation (-40°C to 125°C), while the I-grade operates within -40°C to 85°C.

Q: Are both parts RoHS compliant?

A: Yes. Both PIC16C72T-04E/SS and PIC16C72-04I/SS are ROHS3 compliant with unlimited moisture sensitivity ratings (MSL 1).

Q: Why is the main part classified as Obsolete?

A: The PIC16C72T-04E/SS is an older generation device. The substitute PIC16C72-04I/SS maintains full functional compatibility while offering active product status and ongoing manufacturing support.
