Engineering Selection Recommendations

Primary Substitute: CS5460CK-ISZ is the manufacturer-recommended equivalent for CS5460C-ISZ. Both parts share identical electrical specifications and packaging, with CS5460CK-ISZ offering ROHS3 compliance certification. Both parts are classified as obsolete.

Active Product Alternatives: CS5463K-ISZ and CS5463K-ISZR are active products from Cirrus Logic Inc. that maintain full electrical and mechanical compatibility with the CS5460C-ISZ. These parts feature an expanded voltage supply range (3.135 V ~ 5.25 V) compared to CS5460CK-ISZ (4.5 V ~ 5.5 V), providing greater operational flexibility in low-voltage applications. Both CS5463K variants carry ROHS3 compliance and active product status.

Packaging Consideration: CS5463K-ISZR is supplied in Tape & Reel format, suitable for high-volume automated assembly. CS5463K-ISZ is supplied in Tube format, appropriate for lower-volume or manual assembly operations.

Frequently Asked Questions (FAQ)

Q: Can CS5463K-ISZ replace CS5460C-ISZ in existing designs?

A: Yes. The CS5463K-ISZ maintains identical package geometry (24-SSOP), mounting type (surface mount), supply current (2.9 mA), operating temperature range (-40°C ~ 85°C), input impedance (30 kOhm), and measurement error (0.1%). The expanded voltage supply range (3.135 V ~ 5.25 V) provides additional operational margin.

Q: What is the difference between CS5463K-ISZ and CS5463K-ISZR?

A: Both parts are electrically and mechanically identical. The difference is packaging format: CS5463K-ISZ is supplied in Tube packaging, while CS5463K-ISZR is supplied in Tape & Reel format. Selection depends on assembly process requirements and volume.

Q: Why is CS5460C-ISZ obsolete?

A: Product status is determined by the manufacturer. CS5460CK-ISZ and CS5463K variants are available as active alternatives.

Q: Are all substitute parts RoHS compliant?

A: Yes. CS5460CK-ISZ, CS5463K-ISZ, and CS5463K-ISZR all carry ROHS3 compliance certification. All parts are REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: All parts in this family maintain MSL 3 (168 Hours) rating, indicating identical moisture handling and storage requirements.

Q: Can I use CS5460CK-ISZ as a direct replacement for CS5460C-ISZ?
