Key Parameters

Substitute Part Grouping Explanation

The MCP9600-I/MX and MCP9600-E/MX are direct substitutes within the MCP9600 base product family. Substitution eligibility is determined by the following critical parameters:

• Identical thermocouple input interface and I2C output protocol
• Matching supply current specification (300 µA)
• Identical package configuration (20-VQFN Exposed Pad, 20-MQFN 5x5)
• Identical RoHS3 compliance and MSL rating
• Identical REACH status and ECCN classification

The MCP9600-E/MX extends the operating temperature range to -40°C ~ 125°C compared to the MCP9600-I/MX range of -40°C ~ 85°C, providing broader thermal operating capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MCP9600-E/MX is the appropriate selection for applications currently using or specifying the MCP9600-I/MX. The substitute part maintains full functional and electrical compatibility across all critical parameters including thermocouple input interface, I2C output protocol, supply current, package configuration, and regulatory compliance certifications.

The MCP9600-E/MX carries active product status, ensuring ongoing manufacturer support and availability. Both parts maintain identical RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity.

The extended operating temperature range of the MCP9600-E/MX (-40°C ~ 125°C versus -40°C ~ 85°C) provides additional thermal margin for applications operating at elevated ambient temperatures or requiring broader operational envelope.

Frequently Asked Questions (FAQ)

Q: Are the MCP9600-I/MX and MCP9600-E/MX pin-compatible?

A: Yes. Both devices utilize the identical 20-VQFN Exposed Pad package configuration (20-MQFN 5x5), ensuring direct pin-for-pin compatibility in PCB layouts and socket applications.

Q: What is the primary difference between these two parts?

A: The MCP9600-E/MX extends the operating temperature range to -40°C ~ 125°C compared to the MCP9600-I/MX range of -40°C ~ 85°C. The MCP9600-E/MX also carries active product status, while the MCP9600-I/MX is obsolete.

Q: Can the MCP9600-E/MX be used as a direct replacement in existing designs?

A: Yes. The MCP9600-E/MX is a direct substitute for the MCP9600-I/MX. All electrical specifications, package dimensions, and interface protocols remain identical. The extended temperature range of the substitute part does not introduce incompatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 3 (168 Hours). Regulatory and environmental certifications are equivalent.

Q: What supply current should be expected from either part?

A: Both the MCP9600-I/MX and MCP9600-E/MX operate at 300 µA supply current, ensuring identical power consumption characteristics in system designs.

Q: Is the MCP9600-E/MX available in the same packaging options?
