Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADM1293-2AACPZ is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Supply voltage range: 2.95 V ~ 20 V
• I/O voltage levels: High (1.1V) and Low (0.4V, 0.8V)
• Meter type classification: Single Phase
• Operating temperature range: -40°C ~ 105°C

Mechanical & Package Compatibility Parameters:

• Package type: 16-WQFN Exposed Pad, CSP
• Supplier device package: 16-LFCSP-WQ (4x4)
• Mounting type: Surface Mount

Regulatory & Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level: 3 (168 Hours)

The substitute part ADM1293-1AACPZ shares the same base product number (ADM1293), manufacturer, package footprint, electrical specifications, and regulatory compliance profile. Both components are manufactured by Analog Devices Inc. and function as Single Phase Meter ICs within identical supply voltage and temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The ADM1293-1AACPZ serves as a direct functional substitute for the ADM1293-2AACPZ based on the following engineering criteria:

Compliance & Regulatory Status: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring compatibility with current environmental and regulatory requirements. The substitute part carries Active product status, providing ongoing manufacturer support and availability, whereas the main part is Obsolete.

Electrical & Mechanical Equivalence: The substitute part maintains identical supply voltage specifications (2.95 V ~ 20 V), operating temperature range (-40°C ~ 105°C), I/O voltage levels, and Single Phase meter functionality. Package footprint and mounting specifications are identical, enabling direct PCB-level substitution without layout modifications.

Packaging & Handling: Both components utilize the 16-LFCSP-WQ (4x4) package with identical Moisture Sensitivity Level (MSL 3, 168 Hours), ensuring equivalent handling and storage requirements.

The transition from ADM1293-2AACPZ to ADM1293-1AACPZ is supported by matching electrical performance parameters and identical physical package specifications, with the added benefit of Active product status for the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the ADM1293-1AACPZ directly replace the ADM1293-2AACPZ on existing PCBs?

A: Yes. Both components share identical package specifications (16-LFCSP-WQ 4x4), mounting type (Surface Mount), and electrical operating parameters (supply voltage 2.95 V ~ 20 V, temperature range -40°C ~ 105°C). No PCB layout modifications are required.

Q: What is the primary difference between these two part numbers?

A: The ADM1293-2AACPZ is Obsolete, while the ADM1293-1AACPZ maintains Active product status. The substitute part includes an additional I/O Low voltage threshold option (1.5V) not present in the main part. Both function as Single Phase Meter ICs with identical core electrical specifications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components are ROHS3 Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level (MSL 3, 168 Hours) ratings. Regulatory and environmental compliance profiles are equivalent.

Q: What is the significance of the Voltage - I/O Low parameter difference?

A: The ADM1293-1AACPZ supports three I/O Low voltage thresholds (0.4V, 0.8V, 1.5V), while the ADM1293-2AACPZ supports two (0.8V, 0.4V). This expanded threshold capability in the substitute part provides additional configuration flexibility without affecting core meter functionality or compatibility.

Q: Is the substitute part available in the same packaging format?

A: Yes. Both components are supplied in 16-WQFN Exposed Pad, CSP packages with identical 16-LFCSP-WQ (4x4) supplier device package specifications. Packaging format is fully compatible.

Q: Why should I transition from the obsolete part to the substitute?

A: The ADM1293-2AACPZ is Obsolete, limiting long-term availability and manufacturer support. The ADM1293-1AACPZ maintains Active status, ensuring continued supply, technical support, and compatibility with current production standards while maintaining electrical and mechanical equivalence.
