Key Parameters

Substitute Part Grouping Explanation

Substitution of the EMC6D103-CZC requires matching of critical functional and electrical parameters. The primary substitution criteria are:

Mandatory Matching Parameters:

• Supply voltage range: 3V ~ 3.6V
• Communication interface: SMBus protocol
• Temperature sensing capability: Local and/or remote sensor support
• Operating temperature range compatibility: Minimum -40°C ~ 125°C support
• RoHS3 compliance status
• Surface mount technology

The EMC6D103-CZC combines temperature sensing and fan control functions. Substitute parts are grouped based on their primary function and ability to fulfill the system requirements through either single integrated solutions or complementary component pairs.

Group 1: Temperature Sensor Focus EMC1413-A-AIZL-TR provides digital temperature sensing with SMBus interface, local and remote capability, and extended accuracy specifications. This substitute addresses the temperature monitoring aspect of the original device.

Group 2: Motor/Fan Control Focus EMC2303-1-KP-TR provides PWM-based fan control with SMBus interface compatibility. This substitute addresses the fan control output aspect of the original device.

Parameter Comparison

Engineering Selection Recommendations

For Direct Single-Device Replacement: No single substitute part provides complete functional equivalence to the EMC6D103-CZC. The original device integrates both temperature monitoring and fan control in a single 24-SSOP package. Substitute selection depends on system architecture requirements.

EMC1413-A-AIZL-TR Selection Criteria:

• Primary application: Temperature monitoring and thermal management
• Advantages: Active product status, improved accuracy (±1°C to ±2°C vs. ±3°C to ±5°C), extended MSL rating (2 vs. 3), smaller package footprint (10-MSOP vs. 24-SSOP)
• Limitation: Does not provide integrated fan control output; requires external PWM driver or separate fan control IC
• Compliance: ROHS3 compliant, REACH unaffected, EAR99 classification

EMC2303-1-KP-TR Selection Criteria:

• Primary application: Fan control and PWM output management
• Advantages: Active product status, PWM interface for direct motor/fan control, compact QFN package (12-QFN 4x4)
• Limitation: Does not provide temperature sensing; requires external temperature sensor or separate temperature monitoring IC
• Compliance: ROHS3 compliant, REACH unaffected, EAR99 classification

Dual-Component Architecture: System designs requiring both temperature monitoring and fan control should implement EMC1413-A-AIZL-TR paired with EMC2303-1-KP-TR. This approach provides:

• Full functional coverage of the original EMC6D103-CZC capabilities
• Active product status for both components
• Improved thermal accuracy and MSL ratings
• Reduced overall package footprint compared to the original 24-SSOP device

All substitute parts maintain 3V ~ 3.6V supply voltage compatibility and support extended operating temperature ranges (-40°C ~ 125°C), ensuring thermal performance across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can EMC1413-A-AIZL-TR directly replace EMC6D103-CZC? A: No. EMC1413-A-AIZL-TR provides temperature sensing and SMBus communication but does not include fan control output. It addresses only the temperature monitoring function of the original device. Fan control functionality requires a separate component.

Q: Can EMC2303-1-KP-TR directly replace EMC6D103-CZC? A: No. EMC2303-1-KP-TR provides PWM-based fan control but does not include temperature sensing capability. It addresses only the fan control function of the original device. Temperature monitoring requires a separate component.

Q: What is the recommended approach for replacing EMC6D103-CZC in production designs? A: Implement a dual-component solution using EMC1413-A-AIZL-TR for temperature monitoring and EMC2303-1-KP-TR for fan control. Both components are active products with ROHS3 compliance and operate within the same 3V ~ 3.6V supply voltage range as the original device.

Q: Are the substitute parts compatible with SMBus protocol? A: Yes. EMC1413-A-AIZL-TR provides native SMBus interface. EMC2303-1-KP-TR supports PWM control and is compatible with SMBus-based system architectures for integrated thermal management systems.

Q: What are the package differences between the main part and substitutes? A: EMC6D103-CZC uses 24-SSOP (0.154", 3.90mm width). EMC1413-A-AIZL-TR uses 10-MSOP (0.118", 3.00mm width). EMC2303-1-KP-TR uses 12-QFN (4x4). The substitute parts have smaller footprints, reducing PCB area requirements.

Q: Do the substitute parts have better accuracy specifications? A: EMC1413-A-AIZL-TR provides improved temperature accuracy of ±1°C to ±2°C compared to the original device's ±3°C to ±5°C specification. This represents enhanced thermal measurement precision for temperature-critical applications.

Q: What is the MSL (Moisture Sensitivity Level) difference? A: EMC6D103-CZC has MSL 3 (168 hours). EMC1413-A-AIZL-TR has MSL 2 (1 year), providing superior moisture resistance and extended shelf life. EMC2303-1-KP-TR maintains MSL 3 (168 hours) equivalent to the original device.

Q: Are all substitute parts ROHS3 compliant? A: Yes. EMC1413-A-AIZL-TR and EMC2303-1-KP-TR are both ROHS3 compliant, matching the compliance status of the obsolete EMC6D103-CZC.

Q: What is the operating temperature range of the substitute parts? A: Both EMC1413-A-AIZL-TR and EMC2303-1-KP-TR support -40°C ~ 125°C operating temperature range, exceeding the original device's 0°C ~ 70°C specification and enabling broader application deployment.
