Substitute Part Grouping Explanation

Substitution for the PIC16LC717-E/P is determined by strict alignment of the following electrical and mechanical parameters:

• Core Architecture: PIC 8-bit processor
• Program Memory: 4.6KB OTP
• RAM: 256 x 8 bytes
• I/O Count: 15 pins
• Speed: 20MHz maximum
• Voltage Range: 2.5V ~ 5.5V supply compatibility
• Package: 18-DIP through-hole form factor
• Peripherals: Presence of PWM, WDT, brown-out detection, and POR
• Connectivity: I2C and SPI support

The PIC16LC717-I/P qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is the operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC717-I/P is a direct functional equivalent to the PIC16LC717-E/P with identical electrical and mechanical specifications. The substitute part maintains full compatibility with existing PCB layouts and firmware implementations.

Key selection considerations:

• Product Status: The PIC16LC717-I/P carries Active status, ensuring continued availability and manufacturing support, whereas the main part is classified as Obsolete.
• Operating Temperature Range: The substitute operates within -40°C to 85°C, compared to the main part's -40°C to 125°C range. Applications requiring operation above 85°C require thermal analysis or alternative device selection.
• Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1).
• Inventory: The substitute part is available in production quantities (686 pcs) with verified programmability certification.

Frequently Asked Questions (FAQ)

Q: Can the PIC16LC717-I/P be used as a direct replacement for the PIC16LC717-E/P?

A: Yes, the PIC16LC717-I/P is a direct substitute. Both devices share identical core architecture, memory configuration, I/O count, speed rating, voltage specifications, and 18-DIP package. No PCB modifications or firmware changes are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and operating temperature range. The PIC16LC717-E/P is obsolete with a -40°C to 125°C operating range, while the PIC16LC717-I/P is active with a -40°C to 85°C operating range. The suffix letter (-E vs -I) indicates the temperature grade classification.

Q: Are there any compatibility concerns with the reduced temperature range of the substitute?

A: The PIC16LC717-I/P operates to 85°C maximum ambient temperature. Applications requiring operation above this threshold must evaluate thermal conditions and consider alternative device selection. For standard industrial and commercial temperature ranges, the substitute is fully compatible.

Q: Do both parts use the same package footprint?

A: Yes. Both the PIC16LC717-E/P and PIC16LC717-I/P use the 18-DIP (0.300", 7.62mm) through-hole package with identical pin assignments and mechanical dimensions.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity levels. Regulatory and environmental certifications are equivalent.
