EMC1102-ACZL-TR Equivalent & Substitute Parts

Part Overview

The EMC1102-ACZL-TR is a digital temperature sensor manufactured by Microchip Technology, designed for local and remote temperature measurement applications across the -40°C to 125°C range. This component features an 11-bit resolution output via Simple Serial Transport™ (SST) interface and operates on a 3V to 3.6V supply voltage in an 8-MSOP surface mount package.

The EMC1102-ACZL-TR is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications currently utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EMC1102-ACZL-TR is determined by the following critical parameters:

Temperature Measurement Capability: Both the main part and substitute must support local temperature sensing across the -40°C to 125°C operating range.

Package Compatibility: The 8-MSOP package footprint (0.118", 3.00mm width) is the primary mechanical constraint. Substitute parts must use compatible 8-pin TSSOP or 8-MSOP packages to ensure PCB layout compatibility.

Supply Voltage Range: The main part operates at 3V to 3.6V. Substitute parts with wider supply voltage ranges (such as 3V to 5.5V) remain compatible with the original design voltage specification.

Output Interface and Resolution: The EMC1102-ACZL-TR uses SST output with 11-bit resolution. Substitute parts may employ alternative digital interfaces (I2C/SMBus) provided they deliver equivalent temperature data precision and communication reliability for the application.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH unaffected status to meet current manufacturing and environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The SA56004ADP,118 from NXP USA Inc. is an active product suitable for replacing the obsolete EMC1102-ACZL-TR. Both components meet the same regulatory requirements (ROHS3 compliance and REACH unaffected status) and share identical operating temperature ranges and package dimensions.

The SA56004ADP,118 offers extended supply voltage compatibility (3V to 5.5V versus 3V to 3.6V), providing greater design flexibility for applications with variable power supply conditions. The component maintains equivalent accuracy specifications (±2°C at nominal conditions) and supports local/remote temperature sensing across the full -40°C to 125°C range.

The primary design consideration is the transition from SST output to I2C/SMBus interface. Applications currently using SST protocol must implement firmware or hardware interface adaptation to accommodate the I2C/SMBus communication standard of the substitute part. The 10-bit resolution of the SA56004ADP,118 compared to the 11-bit resolution of the EMC1102-ACZL-TR represents a one-bit reduction in measurement granularity, which may be acceptable depending on application precision requirements.

Frequently Asked Questions (FAQ)

Q: Can the SA56004ADP,118 be used as a direct pin-for-pin replacement?

A: Both components use the 8-MSOP package with identical footprint dimensions (0.118", 3.00mm width), enabling direct PCB placement compatibility. However, the output interface differs: the EMC1102-ACZL-TR uses SST while the SA56004ADP,118 uses I2C/SMBus. Firmware or interface circuitry modifications are required to accommodate this protocol change.

Q: What is the impact of the resolution difference between 11-bit and 10-bit?

A: The EMC1102-ACZL-TR provides 11-bit resolution while the SA56004ADP,118 provides 10-bit resolution. This represents a reduction in measurement granularity of approximately 0.05°C per step. For applications requiring sub-degree precision, this difference should be evaluated against specific accuracy requirements.

Q: Are both parts suitable for the full -40°C to 125°C temperature range?

A: Yes. Both the EMC1102-ACZL-TR and SA56004ADP,118 are rated for operating temperatures from -40°C to 125°C and maintain specified accuracy across this range.

Q: What are the supply voltage considerations for substitution?

A: The EMC1102-ACZL-TR operates at 3V to 3.6V, while the SA56004ADP,118 operates at 3V to 5.5V. The substitute part is compatible with the original supply voltage specification and offers additional flexibility for designs with higher supply voltages.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current manufacturing and environmental regulations.
