Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PIC16F72T-E/SO are identified based on matching the following critical parameters: core processor type (PIC), core size (8-Bit), program memory configuration (4.6KB FLASH), RAM capacity (128 x 8), I/O count (22 pins), supply voltage range (4V ~ 5.5V), connectivity options (I2C, SPI), peripheral set (Brown-out Detect/Reset, POR, PWM, WDT), and package type (28-SOIC). All substitute parts share the same base product number (PIC16F72) and maintain electrical and mechanical compatibility with the original design.

The identified substitutes are PIC16F72-E/SO and PIC16F72-I/SO, which differ primarily in product status and operating temperature range specifications.

Parameter Comparison

Engineering Selection Recommendations

Both PIC16F72-E/SO and PIC16F72-I/SO are active product alternatives to the obsolete PIC16F72T-E/SO. The PIC16F72-E/SO maintains the full operating temperature range of -40°C to 125°C, matching the original part's thermal specifications. The PIC16F72-I/SO operates within a narrower temperature range of -40°C to 85°C, suitable for applications not requiring extended high-temperature operation.

All three parts maintain ROHS3 compliance, REACH unaffected status, and identical electrical and mechanical specifications. Selection between the active substitutes depends on application temperature requirements and availability. Both substitutes are verified as programmable through DiGi-Electronics and are supplied in tube packaging.

Frequently Asked Questions (FAQ)

Q: Can PIC16F72-E/SO and PIC16F72-I/SO be used interchangeably with PIC16F72T-E/SO?

A: Yes, both substitutes are electrically and mechanically compatible. The primary differences are product status (active vs. obsolete) and, for PIC16F72-I/SO, the operating temperature range. Select based on your application's temperature requirements.

Q: What is the difference between PIC16F72-E/SO and PIC16F72-I/SO?

A: Both parts share identical electrical specifications and 28-SOIC packaging. The PIC16F72-E/SO supports the full temperature range (-40°C to 125°C), while PIC16F72-I/SO operates from -40°C to 85°C. Choose PIC16F72-E/SO for applications requiring extended high-temperature operation.

Q: Are all three parts ROHS3 compliant?

A: Yes, PIC16F72T-E/SO, PIC16F72-E/SO, and PIC16F72-I/SO are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Does the 28-SOIC package remain the same across all three parts?

A: Yes, all three parts use the 28-SOIC (0.295", 7.50mm Width) surface mount package with identical pin configuration and mechanical dimensions.

Q: Why is PIC16F72T-E/SO marked as obsolete?

A: The PIC16F72T-E/SO has reached end-of-life status. Active alternatives PIC16F72-E/SO and PIC16F72-I/SO provide continued design support and production availability.
