Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C57CT-04E/SS is determined by strict equivalence across the following critical parameters:

• Core Processor & Architecture: PIC processor family
• Core Size: 8-Bit
• Program Memory: 3KB (2K x 12) OTP
• RAM: 72 x 8 bytes
• I/O Count: 20 pins
• Supply Voltage: 3V ~ 5.5V range
• Peripherals: POR and WDT functionality
• Package: 28-SSOP form factor
• Mounting: Surface Mount

The substitute part PIC16C57C-04I/SS meets all these core electrical and mechanical parameters, ensuring functional and physical compatibility. Differences in product status, operating temperature range, and packaging format (tube vs. standard) do not affect core substitutability but may influence procurement and application considerations.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C57C-04I/SS is a direct functional substitute for the PIC16C57CT-04E/SS. Both devices share identical core electrical specifications, memory architecture, I/O configuration, and package form factor.

The primary distinction is product status: the main part is Obsolete, while the substitute is Active. This status difference ensures continued availability and supply chain support for the PIC16C57C-04I/SS. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, confirming regulatory and environmental compatibility.

The operating temperature range of the substitute (-40°C ~ 85°C) is narrower than the main part (-40°C ~ 125°C). Applications requiring operation above 85°C must evaluate this limitation against specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can PIC16C57C-04I/SS replace PIC16C57CT-04E/SS in existing designs?

A: Yes. Both devices are electrically and mechanically equivalent across all core parameters: 8-bit architecture, 3KB OTP memory, 72 x 8 RAM, 20 I/O pins, 4MHz speed, 3V–5.5V supply range, and 28-SSOP package. No circuit modifications are required.

Q: What is the significance of the product status difference?

A: The main part (Obsolete) is no longer manufactured or supported by Microchip Technology. The substitute (Active) is currently in production and available through authorized distributors, ensuring reliable procurement for new builds and ongoing production.

Q: Does the narrower operating temperature range of the substitute affect compatibility?

A: The substitute operates from -40°C to 85°C, compared to the main part's -40°C to 125°C. If your application requires operation above 85°C, the substitute may not be suitable. For standard industrial and consumer applications within the -40°C to 85°C range, no impact occurs.

Q: Are both parts RoHS compliant?

A: Yes. Both PIC16C57CT-04E/SS and PIC16C57C-04I/SS are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), confirming equivalent environmental and regulatory status.

Q: What packaging format differences exist?

A: The main part uses standard packaging, while the substitute is supplied in Tube format. Both use the 28-SSOP package form factor. Tube packaging does not affect electrical performance or PCB assembly compatibility.
