Engineering Selection Recommendations

PIC16C711-04E/SS is the primary substitute for PIC16C711T-04E/SS. Both parts share identical electrical specifications, memory configuration, I/O count, and package format. The substitute maintains active product status with Microchip Technology, ensuring ongoing availability and support. ROHS3 compliance and MSL rating are equivalent, confirming environmental and handling compatibility.

PIC16C711-04I/SS is a secondary substitute with full electrical and mechanical equivalence. This part differs only in operating temperature range (-40°C ~ 85°C versus -40°C ~ 125°C) and packaging format (Tube). Selection of this variant is appropriate when the reduced temperature specification meets application requirements and tube packaging is acceptable for procurement and assembly workflows.

Both substitute parts are verified as programmable through DiGi-Electronics, confirming functional compatibility with existing development and programming infrastructure.

Frequently Asked Questions (FAQ)

Q: Can PIC16C711-04E/SS directly replace PIC16C711T-04E/SS?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 8-bit PIC core, 4MHz speed, 1.75KB OTP memory, 68 x 8 RAM, 13 I/O pins, 4V ~ 6V supply, and 20-SSOP package. The substitute is active in production, addressing the obsolete status of the original part.

Q: What is the difference between PIC16C711-04E/SS and PIC16C711-04I/SS?

A: The primary difference is operating temperature range. PIC16C711-04E/SS operates from -40°C to 125°C, while PIC16C711-04I/SS operates from -40°C to 85°C. Secondary difference is packaging: PIC16C711-04E/SS uses standard packaging, while PIC16C711-04I/SS is supplied in Tube format. All other electrical and mechanical specifications are identical.

Q: Are these substitutes suitable for high-temperature applications?

A: PIC16C711-04E/SS supports operation to 125°C and is suitable for extended temperature applications. PIC16C711-04I/SS is limited to 85°C maximum and should be selected only when application temperature requirements do not exceed this limit.

Q: Do the substitute parts maintain RoHS and REACH compliance?

A: Yes. Both PIC16C711-04E/SS and PIC16C711-04I/SS are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original PIC16C711T-04E/SS.

Q: What is the significance of MSL rating for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These parts can be stored indefinitely without special moisture control measures, simplifying inventory management and reducing handling complexity.

Q: Are these parts programmable through standard development tools?

A: Both substitute parts are verified as programmable through DiGi-Electronics infrastructure, confirming compatibility with existing PIC development and programming systems.
