CS5467-ISZR Equivalent & Substitute Parts

Part Overview

The CS5467-ISZR is a single-phase energy metering IC manufactured by Cirrus Logic Inc., designed for power management applications requiring accurate energy measurement. This Surface Mount device operates within a 4.75V to 5.25V supply range and delivers 0.1% measurement accuracy. The part is currently Active in product status with 1346 units available in inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory depletion, or when alternative packaging formats better suit manufacturing requirements. The CS5467K-ISZR represents the primary equivalent option, though it carries a Discontinued at DiGi Electronics status and requires verification of electrical parameter compatibility within your specific application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS5467-ISZR is determined by strict alignment across the following critical parameters:

Meter functionality (Single Phase operation), package form factor (28-SSOP with identical 5.30mm width), mounting technology (Surface Mount), measurement accuracy (0.1%), input impedance (30kOhm), operating temperature range (-40°C to 85°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification).

The CS5467K-ISZR qualifies as an equivalent substitute based on these core parameters. However, this part differs in packaging format (Cut Tape versus Tape & Reel) and exhibits variations in I/O voltage thresholds and supply voltage range, which must be evaluated within your circuit design constraints.

Parameter Comparison

Engineering Selection Recommendations

The CS5467-ISZR remains the preferred selection for new designs and production runs due to its Active product status and established inventory availability (1346 units). This part meets all ROHS3 compliance requirements and carries standard Moisture Sensitivity Level 3 handling specifications.

The CS5467K-ISZR may be considered as a substitute only when the primary part becomes unavailable. Critical evaluation must address the I/O voltage threshold differences (Voltage - I/O High: 0.8V versus 4V, and Voltage - I/O Low: 0.2V versus 0.4V) within your specific signal conditioning and interface circuits. The substitute's extended lower supply voltage range (3.135V minimum) may provide operational flexibility in certain power-constrained applications, though this requires circuit-level validation.

The Discontinued at DiGi Electronics status of the CS5467K-ISZR indicates limited future availability through standard distribution channels. Procurement planning should prioritize the active CS5467-ISZR part for supply chain continuity.

Frequently Asked Questions (FAQ)

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

A: Both parts share identical 28-SSOP package dimensions and pinout. However, the I/O voltage threshold differences require circuit evaluation before substitution. The CS5467K-ISZR exhibits significantly higher I/O High voltage (4V versus 0.8V) and higher I/O Low voltage (0.4V versus 0.2V), which may affect signal interpretation in your interface circuits.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging provides components on cut segments of carrier tape, typically used for lower-volume orders or manual assembly. Both formats contain identical components; the difference is in supply and handling format only.

Q: Is the CS5467K-ISZR still available for purchase?

A: The CS5467K-ISZR carries a Discontinued at DiGi Electronics status, indicating limited availability through major distribution channels. Availability through alternative suppliers should be verified before committing to this part for production use.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the CS5467-ISZR and CS5467K-ISZR are ROHS3 Compliant, REACH Unaffected, and classified under EAR99 export control. Both carry identical HTSUS tariff classification (8542.39.0001) and Moisture Sensitivity Level 3 specifications.

Q: What supply voltage range should I design for?

A: The CS5467-ISZR operates within 4.75V to 5.25V. The CS5467K-ISZR extends the lower range to 3.135V. If substitution is considered, design margins must accommodate the specific part's supply voltage range to ensure stable operation across production tolerances and environmental conditions.
