Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS8416-CSZ is determined by the following critical parameters:

• Package compatibility: 28-SOIC form factor with identical 0.295" (7.50mm) width
• Interface protocol support: I2C and SPI communication interfaces
• Operating temperature range: -10°C to 70°C
• Supply voltage compatibility: overlapping or compatible voltage ranges
• RoHS and environmental compliance: ROHS3 compliance and MSL rating
• Audio receiver function classification

The CS8416K-CSZ is identified as a manufacturer-recommended substitute. While this part maintains identical package specifications, interface protocols, operating temperature range, and compliance certifications, it differs in channel configuration (1 channel versus 8 channels) and supply voltage range (3.13V ~ 3.46V versus 3.3V ~ 5V). These differences require evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

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

Selection of the CS8416K-CSZ as a replacement requires evaluation of the following design-specific factors:

• Channel requirement compatibility: The substitute provides 1-channel functionality versus the original 8-channel configuration
• Supply voltage range: The substitute operates within 3.13V to 3.46V, a narrower range than the original 3.3V to 5V specification
• Active product status: The CS8416K-CSZ maintains active production status, ensuring ongoing availability and supply chain support

Frequently Asked Questions (FAQ)

Q: Can the CS8416K-CSZ directly replace the CS8416-CSZ in existing designs?

A: Physical package compatibility is confirmed (28-SOIC form factor). However, functional differences in channel count (1 versus 8) and supply voltage range (3.13V ~ 3.46V versus 3.3V ~ 5V) require design-level evaluation. Direct substitution is not applicable for multi-channel audio reception applications.

Q: Are the interface protocols identical between these parts?

A: Both components support I2C and SPI communication interfaces. Interface protocol compatibility is confirmed.

Q: What is the significance of the product status difference?

A: The CS8416-CSZ is classified as obsolete, indicating discontinued manufacturing. The CS8416K-CSZ maintains active product status, ensuring continued availability, manufacturing support, and compliance updates.

Q: Are environmental compliance certifications equivalent?

A: Both components are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours). Environmental compliance certifications are equivalent.

Q: What are the critical parameters for substitution evaluation?

A: Package form factor, interface protocol support, operating temperature range, supply voltage compatibility, and environmental compliance certifications are the primary parameters determining substitution feasibility.
