Engineering Selection Recommendations

PIC16C712-04E/SS is the primary substitute for the obsolete PIC16C712T-04E/SS. Both parts are manufactured by Microchip Technology with identical electrical and mechanical specifications, including the full operating temperature range of -40°C to 125°C. The PIC16C712-04E/SS carries active product status and verified programmability, ensuring long-term availability and support.

PIC16C712-04I/SS is an alternative substitute with active product status. This part maintains all core electrical specifications and package compatibility. The operating temperature range is limited to -40°C to 85°C, which restricts its use to applications not requiring the extended high-temperature performance of the main part. Selection of this part requires confirmation that the application's thermal environment does not exceed 85°C.

Both substitute parts are ROHS3 compliant and carry MSL Level 1 ratings, meeting modern environmental and handling standards.

Frequently Asked Questions (FAQ)

Q: Can PIC16C712-04E/SS and PIC16C712-04I/SS be used interchangeably with PIC16C712T-04E/SS?

A: Both parts are electrically and mechanically compatible with the main part. PIC16C712-04E/SS is a direct replacement with identical specifications. PIC16C712-04I/SS is compatible for applications operating within -40°C to 85°C; applications requiring operation above 85°C must use PIC16C712-04E/SS.

Q: What is the difference between the temperature ratings?

A: PIC16C712T-04E/SS and PIC16C712-04E/SS both support -40°C to 125°C operation. PIC16C712-04I/SS is rated for -40°C to 85°C. Select based on your application's maximum operating temperature requirement.

Q: Are all three parts in the same package?

A: Yes. All three parts use the 20-SSOP surface mount package with 0.209" width (5.30mm), ensuring identical PCB footprint and assembly compatibility.

Q: What is the significance of "Active" vs. "Obsolete" product status?

A: Obsolete parts (PIC16C712T-04E/SS) are no longer manufactured and have limited availability. Active parts (PIC16C712-04E/SS and PIC16C712-04I/SS) are currently produced by Microchip Technology, ensuring ongoing supply and support.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry MSL Level 1 ratings, meeting current environmental and handling standards.
