Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS8416-CZZ is evaluated based on the following critical parameters that define functional and physical compatibility:

Package Compatibility: Both the main part and substitute must use the 28-TSSOP surface mount package to ensure PCB layout compatibility without redesign.

Interface Compatibility: Both parts must support I2C and SPI interfaces to maintain communication protocol compatibility with existing system designs.

Operating Temperature Range: The substitute must support the same or wider operating temperature range (-10°C ~ 70°C) to ensure thermal performance equivalence.

Supply Voltage Range: The substitute must operate within or be compatible with the 3.3V to 5V supply voltage specification.

Compliance & Certification: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity levels to meet regulatory and manufacturing requirements.

The CS8416K-CZZ is identified as a manufacturer-recommended substitute based on these core compatibility criteria.

Parameter Comparison

Engineering Selection Recommendations

The CS8416K-CZZ is the manufacturer-recommended substitute for the obsolete CS8416-CZZ. Both components share identical package specifications, interface protocols, operating temperature ranges, and compliance certifications (ROHS3, MSL 3).

The primary distinction is product status: the CS8416-CZZ is obsolete, while the CS8416K-CZZ maintains active production status, ensuring ongoing availability and supply chain support.

Both parts maintain equivalent moisture sensitivity levels and regulatory compliance, supporting direct substitution in manufacturing and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the CS8416K-CZZ be used as a direct replacement for the CS8416-CZZ?

A: Yes. Both components share the same 28-TSSOP package, I2C/SPI interface protocols, operating temperature range (-10°C ~ 70°C), and compliance certifications. The CS8416K-CZZ is the manufacturer-recommended substitute.

Q: What is the primary difference between these two parts?

A: The CS8416-CZZ is classified as obsolete, while the CS8416K-CZZ maintains active production status. This ensures continued availability and supply chain reliability for the CS8416K-CZZ.

Q: Are there any voltage supply differences I should consider?

A: The CS8416-CZZ operates at 3.3V ~ 5V, while the CS8416K-CZZ operates at 3.13V ~ 3.46V. System designs must ensure the power supply voltage falls within the CS8416K-CZZ range for proper operation.

Q: Will the CS8416K-CZZ fit the same PCB footprint as the CS8416-CZZ?

A: Yes. Both components use the 28-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width), requiring no PCB layout modifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the CS8416-CZZ and CS8416K-CZZ are ROHS3 compliant and maintain equivalent moisture sensitivity levels (MSL 3, 168 Hours).
