Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADE7169ASTZF16 is determined by the following critical parameters:

• Meter Type: Single-phase energy metering functionality
• Measurement Accuracy: 0.1% error specification
• Operating Temperature Range: -40°C to 85°C
• Supply Voltage Compatibility: Overlapping or compatible voltage ranges
• Mounting Type: Surface mount technology
• Manufacturer: Analog Devices Inc. (same product family)

The ADE7953ACPZ qualifies as a substitute based on matching meter type, measurement error specification, operating temperature range, and surface mount configuration. Both components are single-phase energy meter ICs from Analog Devices with identical measurement accuracy and temperature specifications. The substitute part maintains functional equivalence for single-phase metering applications despite differences in package form factor and supply current characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ADE7953ACPZ is an active product substitute for the obsolete ADE7169ASTZF16. Both components meet the core functional requirements for single-phase energy metering with 0.1% measurement accuracy across the -40°C to 85°C operating temperature range.

Key considerations for selection:

• Product Status: The ADE7953ACPZ is active and maintains ongoing manufacturer support, whereas the ADE7169ASTZF16 is obsolete with limited availability.
• Supply Voltage Range: The ADE7953ACPZ operates within 3.0V to 3.6V, which overlaps with the ADE7169ASTZF16 range of 2.4V to 3.7V. Designs operating below 3.0V require verification of compatibility.
• Supply Current: The ADE7953ACPZ draws 7mA compared to 4mA for the ADE7169ASTZF16, representing a 75% increase in current consumption.
• Package Footprint: The ADE7953ACPZ uses a smaller 28-LFCSP-WQ (5x5) package versus the 64-LQFP (10x10) package of the original part, requiring PCB layout redesign.
• Compliance: The ADE7953ACPZ carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ADE7953ACPZ directly replace the ADE7169ASTZF16 without PCB modifications?

A: No. The ADE7953ACPZ uses a 28-LFCSP-WQ (5x5) package compared to the 64-LQFP (10x10) package of the ADE7169ASTZF16. PCB layout redesign is required, including footprint changes and signal routing adjustments.

Q: Are the measurement accuracy specifications identical?

A: Yes. Both the ADE7169ASTZF16 and ADE7953ACPZ deliver 0.1% measurement error, maintaining equivalent metering precision for single-phase energy applications.

Q: What is the impact of increased supply current in the ADE7953ACPZ?

A: The ADE7953ACPZ requires 7mA versus 4mA for the ADE7169ASTZF16. Power supply design must accommodate this 3mA increase. For battery-powered or low-power applications, this difference may affect system runtime or require power supply recalculation.

Q: Is the supply voltage range compatible between these parts?

A: Partial compatibility exists. The ADE7953ACPZ operates from 3.0V to 3.6V, while the ADE7169ASTZF16 operates from 2.4V to 3.7V. Designs requiring operation below 3.0V cannot use the ADE7953ACPZ as a substitute.

Q: What regulatory compliance differences exist?

A: The ADE7953ACPZ is ROHS3 compliant and REACH unaffected. The ADE7169ASTZF16 compliance status is not specified in the provided data. Both parts carry EAR99 ECCN classification and 8542.39.0001 HTSUS code.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both the ADE7169ASTZF16 and ADE7953ACPZ operate across -40°C to 85°C, meeting industrial temperature requirements for single-phase energy metering systems.
