Substitute Part Grouping Explanation
Substitution of the ADE5169ASTZF62 is determined by the following critical parameters:
- Meter Type: Single Phase metering functionality
- Measurement Accuracy: 0.1% measurement error specification
- Supply Voltage Range: Operating within 2.4 V to 3.7 V envelope
- Operating Temperature Range: -40°C to 85°C
- Manufacturer: Analog Devices Inc. (same manufacturer ensures design continuity and firmware compatibility)
- Mounting Type: Surface Mount technology
The ADE7953ACPZ qualifies as a substitute based on matching meter type, measurement error specification, overlapping supply voltage range, identical operating temperature range, and surface mount packaging. However, the package form factor differs (28-LFCSP-WQ versus 64-LQFP), which requires PCB redesign considerations.

Engineering Selection Recommendations
The ADE7953ACPZ is an active product from Analog Devices Inc. and represents the current generation single-phase meter IC. Selection of this substitute is supported by:
- Product Status: Active status ensures ongoing availability, technical support, and supply chain continuity
- Compliance: RoHS3 Compliant and REACH Unaffected certifications meet current regulatory requirements
- Functional Equivalence: Identical meter type, measurement error specification, and operating temperature range
- Supply Voltage Compatibility: The ADE7953ACPZ supply voltage range (3 V ~ 3.6 V) is contained within the ADE5169ASTZF62 range (2.4 V ~ 3.7 V), ensuring compatibility in most applications
Critical Design Consideration: The ADE7953ACPZ uses a 28-pin LFCSP package (5x5 mm) compared to the 64-pin LQFP package (10x10 mm) of the ADE5169ASTZF62. This package change requires PCB layout redesign, including pin reassignment, signal routing, and thermal management modifications. Firmware or application code may require updates to accommodate the different pin configuration and reduced pin count.
Frequently Asked Questions (FAQ)
Q: Can the ADE7953ACPZ be used as a direct pin-for-pin replacement for the ADE5169ASTZF62?
A: No. The ADE7953ACPZ uses a 28-pin LFCSP package while the ADE5169ASTZF62 uses a 64-pin LQFP package. Pin assignments differ significantly. PCB redesign is required.
Q: Are the measurement accuracy specifications identical between these parts?
A: Yes. Both parts specify 0.1% measurement error, meeting the same metering accuracy requirements.
Q: What is the impact of the higher supply current in the ADE7953ACPZ?
A: The ADE7953ACPZ draws 7 mA compared to 4.4 mA for the ADE5169ASTZF62. Power supply design must accommodate this increased current draw. Battery-powered applications may experience reduced operating time.
Q: Are both parts suitable for the same operating temperature range?
A: Yes. Both parts operate across -40°C to 85°C, supporting identical environmental specifications.
Q: What compliance certifications apply to the ADE7953ACPZ?
A: The ADE7953ACPZ is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.
Q: Why is the ADE5169ASTZF62 listed as Obsolete?
A: The ADE5169ASTZF62 has reached end-of-life status. Analog Devices Inc. has transitioned to newer meter IC designs such as the ADE7953ACPZ for active product lines.
Q: Can I use the ADE7953ACPZ in new designs?
A: Yes. The ADE7953ACPZ is an active product with ongoing manufacturer support, making it suitable for new designs and long-term production.
