Substitute Part Grouping Explanation

Substitute parts for the PIC16C717T-E/SS are identified based on strict electrical and mechanical compatibility within the PIC® 16C microcontroller family. The substitution logic is determined by the following critical parameters:

• Core Processor & Architecture: PIC processor family
• Core Size: 8-Bit processing capability
• Speed: 20MHz operation
• Program Memory: 4.6KB OTP capacity
• RAM: 256 x 8 byte configuration
• Supply Voltage: 4V ~ 5.5V operating range
• Package: 20-SSOP form factor with identical pin count and spacing
• Peripherals: Presence of I2C, SPI, PWM, WDT, and brown-out detection
• Data Converters: 6-channel 10-bit A/D converter

The identified substitutes—PIC16C717-E/SS and PIC16C717-I/SS—maintain identical electrical specifications and package geometry, ensuring direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

PIC16C717-E/SS is the primary substitute for the obsolete PIC16C717T-E/SS. Both parts share identical electrical and mechanical specifications with full parameter alignment. The PIC16C717-E/SS carries Active product status, ensuring ongoing availability and supply chain support. This part is DiGi-Electronics Programmable Verified and maintains ROHS3 compliance and unlimited moisture sensitivity rating.

PIC16C717-I/SS serves as an alternative substitute with identical core functionality and package compatibility. This part also carries Active product status and is DiGi-Electronics Programmable Verified. The operating temperature range is limited to -40°C ~ 85°C (TA), compared to the -40°C ~ 125°C range of the main part and PIC16C717-E/SS. Selection of PIC16C717-I/SS is appropriate for applications where the reduced upper temperature limit does not conflict with system requirements. Packaging is supplied in Tube format.

Both substitutes maintain full compliance with RoHS3 and REACH regulations, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can PIC16C717-E/SS and PIC16C717-I/SS be used interchangeably with PIC16C717T-E/SS?

A: Yes, both parts are direct electrical and mechanical substitutes. All three devices share identical core processor architecture, memory configuration, I/O count, peripheral set, supply voltage range, and 20-SSOP package geometry. Pin-for-pin compatibility is confirmed.

Q: What is the difference between PIC16C717-E/SS and PIC16C717-I/SS?

A: The primary difference is the operating temperature range. PIC16C717-E/SS operates from -40°C to 125°C, while PIC16C717-I/SS operates from -40°C to 85°C. Additionally, PIC16C717-I/SS is supplied in Tube packaging, whereas PIC16C717-E/SS packaging is not specified. Both parts are electrically and functionally identical in all other parameters.

Q: Why is the original PIC16C717T-E/SS marked as Obsolete?

A: Obsolete status indicates that Microchip Technology has discontinued active production and support for this specific part number variant. The substitute parts PIC16C717-E/SS and PIC16C717-I/SS remain in Active production status, providing continued availability and supply chain stability.

Q: Are there any compliance or certification differences between the three parts?

A: No. All three parts maintain identical RoHS3 compliance, REACH Unaffected status, MSL Level 1 (Unlimited), and equivalent ECCN and HTSUS classifications. Regulatory and environmental compliance is uniform across all three devices.

Q: What should I consider when selecting between the two substitutes?

A: If your application requires operation at temperatures above 85°C, PIC16C717-E/SS is the required choice due to its extended temperature range to 125°C. If your application operates within -40°C to 85°C, either part is suitable. Packaging preference (Tube vs. unspecified) may also influence selection based on procurement and assembly requirements.

Q: Is the 20-SSOP package identical across all three parts?

A: Yes. All three parts use the 20-SSOP package with identical dimensions (0.209" width, 5.30mm). PCB footprints, land patterns, and assembly processes are directly compatible.
