CS5467-ISZ Equivalent & Substitute Parts

Part Overview

The CS5467-ISZ is a single-phase energy metering IC manufactured by Cirrus Logic Inc., designed for power management applications requiring precise energy measurement. This Surface Mount device operates within a 4.75V to 5.25V supply range and delivers 0.1% measurement accuracy, making it suitable for utility metering and power monitoring systems. The part is currently Active in product status with 2900 units available in inventory. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require alternative qualified components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS5467-ISZ is determined by the following critical parameters:

• Meter Type: Must be Single Phase to maintain functional equivalence
• Package / Case: Must be 28-SSOP with identical 0.209" (5.30mm) width for PCB layout compatibility
• Measurement Error: Must be 0.1% or better to preserve metering accuracy specifications
• Voltage - Supply Range: Must encompass or match the 4.75V to 5.25V operating window
• Current - Supply: Must be 4.6mA or lower to maintain power budget compatibility
• Operating Temperature Range: Must cover -40°C to 85°C minimum
• Mounting Type: Must be Surface Mount for assembly process compatibility
• RoHS & Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The CS5467K-ISZ qualifies as a manufacturer-recommended substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The CS5467-ISZ is the primary selection for new designs and active production due to its Active product status and current inventory availability of 2900 units. The CS5467K-ISZ serves as a qualified substitute when the main part becomes unavailable, though it is currently listed as Discontinued at DiGi Electronics. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and equivalent electrical performance within the specified parameters. The CS5467K-ISZ offers a wider supply voltage range (3.135V to 5.25V versus 4.75V to 5.25V), which may provide additional design flexibility in applications with lower supply voltages, provided the circuit design accommodates this extended range. Both parts are suitable for direct substitution in existing designs without PCB layout modifications due to identical 28-SSOP packaging.

Frequently Asked Questions (FAQ)

Q: Can the CS5467K-ISZ be used as a direct replacement for the CS5467-ISZ?

A: Yes. Both parts share identical package geometry (28-SSOP), measurement accuracy (0.1%), supply current (4.6mA), operating temperature range (-40°C to 85°C), and compliance certifications (ROHS3, REACH unaffected). The CS5467K-ISZ operates across a wider supply voltage range (3.135V to 5.25V), making it compatible with the CS5467-ISZ's specified 4.75V to 5.25V window.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: identical Meter Type (Single Phase), matching 28-SSOP package dimensions, equivalent or superior measurement error (0.1%), supply voltage range compatibility, identical supply current (4.6mA), matching operating temperature range (-40°C to 85°C), Surface Mount mounting type, and maintained compliance certifications (ROHS3, REACH unaffected).

Q: Are there any differences in electrical performance between these parts?

A: Both parts deliver identical measurement error (0.1%), supply current (4.6mA), and operating temperature specifications. The CS5467K-ISZ features a lower minimum supply voltage (3.135V versus 4.75V), which expands its operational envelope while remaining fully compatible with the CS5467-ISZ's specified voltage window.

Q: What is the current availability status of each part?

A: The CS5467-ISZ is Active with 2900 units in stock. The CS5467K-ISZ is Discontinued at DiGi Electronics with 1448 units available, making it a secondary option for inventory planning purposes.

Q: Are PCB layout modifications required when substituting these parts?

A: No. Both parts use identical 28-SSOP packaging with 0.209" (5.30mm) width, eliminating the need for PCB redesign or footprint changes.
