CS5460CK-ISZ Equivalent & Substitute Parts

Part Overview

The CS5460CK-ISZ is a Single Phase Meter IC manufactured by Cirrus Logic Inc., classified as a Power Management (PMIC) component. This device functions as a single-phase power and energy measurement integrated circuit in a 24-SSOP surface mount package. The CS5460CK-ISZ is currently listed with Obsolete product status. Identification of equivalent and substitute parts is necessary due to the obsolete classification, which may result in limited availability and extended lead times. Active alternative models from the same manufacturer provide functionally compatible solutions with enhanced supply chain accessibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CS5460CK-ISZ are determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Meter Type: Single Phase (identical function)
• Input Impedance: 30 kOhm (identical specification)
• Measurement Error: 0.1% (identical accuracy)
• Voltage - I/O High: 4 V (identical logic level)
• Voltage - I/O Low: 0.4 V (identical logic level)
• Current - Supply: 2.9 mA (identical power consumption)
• Operating Temperature Range: -40°C ~ 85°C (identical thermal specification)
• Package / Case: 24-SSOP (identical physical form factor)
• Mounting Type: Surface Mount (identical assembly method)
• RoHS Status: ROHS3 Compliant (identical environmental compliance)
• Moisture Sensitivity Level: 3 (168 Hours) (identical handling requirement)

Allowable Variation:

• Voltage - Supply range may be broader in substitute parts without compromising compatibility, provided the original supply voltage range (4.5 V ~ 5.5 V) falls within the substitute's specified range.
• Packaging format may differ (Tube versus Tape & Reel) without affecting electrical or mechanical compatibility.
• Product Status transition from Obsolete to Active represents supply chain improvement without functional change.

Engineering Selection Recommendations

CS5463K-ISZ and CS5463K-ISZR Selection Basis:

Both CS5463K-ISZ and CS5463K-ISZR are direct functional equivalents to the CS5460CK-ISZ. The substitution is valid based on the following engineering criteria:

1. Electrical Equivalence: All critical electrical parameters—input impedance, measurement error, I/O voltage levels, supply current, and operating temperature range—are identical across all three parts.

2. Physical Compatibility: All three parts utilize the identical 24-SSOP package form factor with 0.209" (5.30 mm) width, ensuring PCB layout and assembly compatibility without modification.

3. Compliance Alignment: All parts maintain ROHS3 compliance, identical MSL rating (3, 168 Hours), REACH Unaffected status, and matching ECCN and HTSUS classifications, ensuring regulatory and supply chain consistency.

4. Supply Voltage Compatibility: The substitute parts feature a broader supply voltage range (3.135 V ~ 5.25 V) compared to the main part (4.5 V ~ 5.5 V). The original specification range is fully contained within the substitute range, confirming electrical compatibility in all existing applications.

5. Product Status Advantage: Both substitute parts carry Active product status, providing superior long-term availability and supply chain reliability compared to the Obsolete classification of the main part.

Packaging Format Selection:

• CS5463K-ISZ (Tube packaging): Suitable for applications requiring manual component handling, prototyping, or low-volume assembly operations.

• CS5463K-ISZR (Tape & Reel packaging): Suitable for high-volume automated assembly operations and production environments utilizing pick-and-place equipment.

Frequently Asked Questions (FAQ)

Q: Are the CS5463K-ISZ and CS5463K-ISZR electrically identical to the CS5460CK-ISZ?

A: Yes. Both substitute parts maintain identical electrical specifications across all critical parameters: meter type, input impedance, measurement error, I/O voltage levels, supply current, and operating temperature range. The parts are direct functional equivalents.

Q: What is the significance of the broader supply voltage range in the substitute parts?

A: The substitute parts specify a supply voltage range of 3.135 V ~ 5.25 V, compared to the main part's 4.5 V ~ 5.5 V. This broader range in the substitutes is fully compatible with the original specification, as the original range is completely contained within the substitute range. No circuit modifications are required.

Q: Can I use CS5463K-ISZR in place of CS5463K-ISZ?

A: Yes. The only difference between these two parts is the packaging format: CS5463K-ISZ is supplied in Tube packaging, while CS5463K-ISZR is supplied in Tape & Reel format. Electrical and mechanical specifications are identical. Selection depends on assembly process requirements.

Q: Will the substitute parts fit the existing PCB layout designed for the CS5460CK-ISZ?

A: Yes. All three parts use the identical 24-SSOP package with 0.209" (5.30 mm) width. No PCB layout modifications are required for substitution.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All three parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification, and matching HTSUS code. Regulatory and supply chain documentation remains consistent.

Q: Why is the CS5460CK-ISZ listed as Obsolete?

A: The CS5460CK-ISZ carries Obsolete product status, indicating that the manufacturer has discontinued active production and support. The CS5463K-ISZ and CS5463K-ISZR are Active alternatives that provide identical functionality with ongoing manufacturer support and improved supply chain availability.

Q: What is the Moisture Sensitivity Level (MSL) rating, and does it differ between parts?

A: All three parts carry an MSL rating of 3 (168 Hours), indicating identical moisture handling requirements. Components must be stored in controlled humidity environments and used within 168 hours of exposure to ambient conditions above specified moisture levels.

Q: Can I mix packaging formats in a single production run?

A: Yes. CS5463K-ISZ (Tube) and CS5463K-ISZR (Tape & Reel) are electrically and mechanically identical. Mixing formats is permissible from a technical standpoint; however, assembly process optimization typically favors consistent packaging format selection for automated production environments.
