Key Parameters

Substitute Part Grouping Explanation

Substitution for the EMC6D103-CZC-TR is determined by the following critical parameters:

Primary Substitution Criteria:

• Function: Fan Control and/or Temperature Monitoring capability
• Output Interface: SMBus communication protocol
• Supply Voltage Compatibility: 3.3V nominal operation
• Sensor Configuration: Internal and/or external temperature sensing
• Package Type: Surface mount configuration suitable for PCB integration
• Compliance: ROHS3 compliance and REACH unaffected status

The substitute parts identified are grouped into two functional categories:

Category 1 - Temperature Sensor Focus (EMC1413-A-AIZL-TR): Provides digital temperature sensing with local/remote capability and SMBus output, addressing the temperature monitoring function of the original part.

Category 2 - Motor/Fan Driver Focus (EMC2303-1-KP-TR): Provides PWM-based fan control functionality with SMBus-compatible interface, addressing the fan control function of the original part.

Both substitutes maintain ROHS3 compliance, operate within compatible voltage ranges (3.0V to 3.6V), and are manufactured by Microchip Technology with Active product status.

Engineering Selection Recommendations

For Direct Temperature Monitoring Replacement:

The EMC1413-A-AIZL-TR is suitable when the primary requirement is temperature sensing with SMBus output. This part maintains ROHS3 compliance and Active product status. The extended operating temperature range (-40°C to 125°C) exceeds the original part's specification. The 10-MSOP package requires PCB layout modification compared to the 24-SSOP original. Accuracy specification (±1°C to ±2°C) is superior to the original part's ±3°C to ±5°C range.

For Fan Control Driver Replacement:

The EMC2303-1-KP-TR addresses the fan control function through PWM interface. This part maintains ROHS3 compliance and Active product status. The 12-QFN package differs from the original 24-SSOP footprint. This substitute requires integration with a separate temperature sensor to replicate the combined monitoring and control functionality of the original EMC6D103-CZC-TR.

Combined System Approach:

Applications requiring both temperature monitoring and fan control may implement the EMC1413-A-AIZL-TR for sensing and the EMC2303-1-KP-TR for drive control, with system-level integration via SMBus and PWM interfaces.

All recommended substitutes are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can the EMC1413-A-AIZL-TR directly replace the EMC6D103-CZC-TR?

A: The EMC1413-A-AIZL-TR provides temperature sensing functionality with SMBus output compatible with the original part. However, it does not include integrated fan control output. Direct replacement is possible for applications requiring temperature monitoring only. Applications requiring fan control output must implement additional driver circuitry or use the EMC2303-1-KP-TR in combination.

Q: What are the package differences between substitute parts and the original?

A: The EMC6D103-CZC-TR uses 24-SSOP packaging. The EMC1413-A-AIZL-TR uses 10-MSOP packaging, and the EMC2303-1-KP-TR uses 12-QFN (4x4) packaging. PCB layout and footprint modifications are required for either substitute. Pin-to-pin compatibility does not exist; functional integration must be redesigned.

Q: Are the substitute parts compatible with the original supply voltage?

A: The EMC6D103-CZC-TR operates at 3.3V. Both substitutes operate across 3.0V to 3.6V ranges, which encompasses the original 3.3V specification. Supply voltage compatibility is maintained.

Q: What is the impact of different Moisture Sensitivity Levels?

A: The original part has MSL 1 (Unlimited shelf life). The EMC1413-A-AIZL-TR has MSL 2 (1 Year shelf life), and the EMC2303-1-KP-TR has MSL 3 (168 Hours shelf life). Lower MSL ratings require stricter moisture control during storage and handling. Component procurement and inventory management procedures may require adjustment.

Q: Do the substitute parts maintain regulatory compliance?

A: Both substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original EMC6D103-CZC-TR.

Q: How do the temperature sensing accuracies compare?

A: The EMC6D103-CZC-TR specifies ±3°C local and ±5°C remote accuracy. The EMC1413-A-AIZL-TR specifies ±1°C to ±2°C accuracy, representing improved precision. The EMC2303-1-KP-TR does not include temperature sensing functionality.
