Engineering Selection Recommendations

PIC16C716-20E/SS is the primary substitute for the obsolete PIC16C716T-20E/SS. This part maintains identical electrical and thermal specifications across the full -40°C to 125°C operating range, with active product status ensuring long-term availability and supply chain continuity. ROHS3 compliance and verified programmability confirm compatibility with current manufacturing standards.

PIC16C716-20I/SS serves as an alternative substitute with identical core functionality and electrical parameters. The operating temperature range is limited to -40°C to 85°C, making this part suitable for applications not requiring the extended upper temperature specification. Active product status and verified programmability support production deployment. Packaging is specified as Tube format.

Selection between PIC16C716-20E/SS and PIC16C716-20I/SS depends on application temperature requirements and packaging preferences. Both parts are electrically and functionally equivalent within their respective operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can PIC16C716-20E/SS directly replace PIC16C716T-20E/SS?

A: Yes. Both parts share identical core processor architecture, memory configuration, I/O count, voltage supply range, and 20-SSOP package. The main difference is product status: PIC16C716T-20E/SS is obsolete while PIC16C716-20E/SS is active. Electrical and functional compatibility is complete.

Q: What is the difference between PIC16C716-20E/SS and PIC16C716-20I/SS?

A: The primary difference is operating temperature range. PIC16C716-20E/SS operates from -40°C to 125°C, while PIC16C716-20I/SS operates from -40°C to 85°C. All other electrical specifications, memory, I/O, and peripherals are identical. Packaging format also differs: PIC16C716-20I/SS is supplied in Tube format.

Q: Are these parts pin-compatible?

A: Yes. All three parts use the 20-SSOP package with identical pinout and electrical characteristics, ensuring direct board-level compatibility.

Q: Do these substitutes maintain RoHS compliance?
