Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5460A-BSZ is determined by strict equivalence across the following critical parameters:

• Meter Type: Single Phase (identical functional requirement)
• Package / Case: 24-SSOP (0.209", 5.30mm Width) (identical footprint and pin count)
• Input Impedance: 30kOhm (identical measurement interface)
• Measurement Error: 0.1% (identical accuracy specification)
• Operating Temperature: -40°C ~ 85°C (identical thermal range)
• Mounting Type: Surface Mount (identical assembly method)
• RoHS Status: ROHS3 Compliant (identical environmental compliance)
• Moisture Sensitivity Level: 3 (168 Hours) (identical handling requirements)

The CS5460AK-BSZ meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete CS5460A-BSZ.

Parameter Comparison

Engineering Selection Recommendations

The CS5460AK-BSZ is the direct substitute for the obsolete CS5460A-BSZ. Both devices share identical functional specifications for single-phase energy metering, package geometry, and measurement accuracy. The CS5460AK-BSZ maintains active product status with Cirrus Logic Inc., ensuring continued availability and technical support.

The CS5460AK-BSZ features an expanded supply voltage range (3.3 V ~ 5 V) compared to the CS5460A-BSZ (4.75 V ~ 5.25 V), providing greater design flexibility for systems operating at lower supply voltages while maintaining full backward compatibility for existing 5V designs.

Both devices carry identical environmental compliance certifications (ROHS3, REACH Unaffected, EAR99) and moisture sensitivity specifications, eliminating any compliance or handling requirement changes during substitution.

Frequently Asked Questions (FAQ)

Q: Can the CS5460AK-BSZ directly replace the CS5460A-BSZ in existing designs?

A: Yes. Both devices share identical package geometry (24-SSOP), pin count, functional specifications, and operating parameters. No PCB redesign or layout modifications are required.

Q: What is the difference in supply voltage range between these parts?

A: The CS5460A-BSZ operates at 4.75 V ~ 5.25 V, while the CS5460AK-BSZ operates at 3.3 V ~ 5 V. The CS5460AK-BSZ supports a wider lower voltage range, making it suitable for systems with variable or lower supply voltages. Both are compatible with standard 5V supply designs.

Q: Are there any differences in measurement accuracy or performance?

A: No. Both devices specify 0.1% measurement error, 30kOhm input impedance, 2.9mA supply current, and identical operating temperature ranges (-40°C ~ 85°C).

Q: What is the packaging difference between these parts?

A: The CS5460A-BSZ packaging is not specified in the available data. The CS5460AK-BSZ is supplied in Tube packaging. Both use identical 24-SSOP case geometry for surface mount assembly.

Q: Are there any compliance or certification differences?

A: No. Both devices are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity levels are identical at MSL 3 (168 Hours).

Q: Why is the CS5460A-BSZ classified as obsolete?

A: The CS5460A-BSZ has reached end-of-life status with the manufacturer. The CS5460AK-BSZ is the active equivalent product and is the recommended selection for new designs and ongoing procurement.
