Substitute Part Grouping Explanation

Substitution of the CS5463-IS is determined by strict equivalence across the following critical parameters:

• Meter Type: Single Phase (required match)
• Package / Case: 24-SSOP form factor (required match for PCB compatibility)
• Mounting Type: Surface Mount (required match)
• Input Impedance: 30kOhm (required match)
• Measurement Error: 0.1% (required match for measurement accuracy)
• Voltage - Supply: 4.75 V ~ 5.25 V (required match)
• Current - Supply: 2.9mA (required match)
• Voltage - I/O High / Low: 0.8V / 0.2V (required match for signal compatibility)
• Operating Temperature: -40°C ~ 85°C (required match)

The CS5463-ISZ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Both parts share the same base product number (CS5463) and are manufactured by Cirrus Logic Inc.

Parameter Comparison

Engineering Selection Recommendations

The CS5463-ISZ is a direct functional equivalent to the CS5463-IS. Both components meet identical electrical and mechanical specifications required for single-phase energy metering applications.

The primary distinction between these parts is regulatory compliance status. The CS5463-ISZ carries ROHS3 compliance, whereas the CS5463-IS is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the CS5463-ISZ is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging differs between the two parts: CS5463-IS packaging is unspecified, while CS5463-ISZ is supplied in Tube packaging. This distinction affects handling, storage, and assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can CS5463-ISZ replace CS5463-IS in existing designs?

A: Yes. The CS5463-ISZ is electrically and mechanically equivalent to the CS5463-IS. All critical parameters—meter type, package form factor, supply voltage, measurement accuracy, and operating temperature range—are identical. Direct substitution is possible without circuit modification.

Q: What is the significance of the RoHS compliance difference?

A: The CS5463-ISZ is ROHS3 compliant while the CS5463-IS is RoHS non-compliant. This distinction is relevant only if your application or market region requires RoHS compliance. From a functional standpoint, both parts perform identically.

Q: Are there any package compatibility concerns?

A: Both parts use the 24-SSOP surface mount package with identical dimensions (0.209", 5.30mm Width). PCB footprints and assembly processes are compatible. The difference in packaging format (Tube for CS5463-ISZ versus unspecified for CS5463-IS) affects logistics and handling only, not electrical or mechanical compatibility.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the CS5463-IS and CS5463-ISZ operate from -40°C to 85°C, ensuring equivalent thermal performance in the same application environment.

Q: What is the measurement accuracy of these parts?

A: Both parts deliver 0.1% measurement error, meeting identical accuracy specifications for energy metering applications.
