TAS5508PAG Equivalent & Substitute Parts

Part Overview

The TAS5508PAG is an 8-channel audio modulator IC in 64-TQFP surface mount packaging, designed for digital audio interfacing applications. It supports I2C and I2S interfaces with a supply voltage range of 3V to 3.6V and operates across a frequency specification of 32kHz to 192kHz. The TAS5508PAG is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5508PAG is determined by strict equivalence across the following critical parameters:

• Functional equivalence: 8-channel audio modulator with identical modulation capability
• Interface compatibility: I2C and I2S interface support
• Electrical specifications: 3V to 3.6V supply voltage range and 32kHz to 192kHz frequency specification
• Package compatibility: 64-TQFP (10x10) surface mount package
• Operating temperature range: 0°C to 70°C (TA)
• Regulatory compliance: ROHS3 compliance and MSL 4 rating

The TAS5508CPAG meets all these criteria and is classified as an active product, providing a direct functional and electrical substitute for the obsolete TAS5508PAG.

Parameter Comparison

Engineering Selection Recommendations

The TAS5508CPAG is the direct substitute for the TAS5508PAG. Both components are manufactured by Texas Instruments and maintain identical electrical, functional, and package specifications. The primary distinction is product status: the TAS5508PAG is obsolete while the TAS5508CPAG is active and currently in production.

Selection of the TAS5508CPAG is appropriate for:

• Replacement of failed TAS5508PAG components in existing systems
• New designs requiring 8-channel audio modulation with I2C/I2S interface
• Applications requiring ROHS3 compliance and MSL 4 handling

Both parts maintain equivalent regulatory compliance, including ROHS3 status and REACH unaffected classification. The TAS5508CPAG is supplied in Tray packaging with significantly higher inventory availability compared to the obsolete TAS5508PAG.

Frequently Asked Questions (FAQ)

Q: Can the TAS5508CPAG directly replace the TAS5508PAG in existing designs?

A: Yes. The TAS5508CPAG is electrically and functionally equivalent to the TAS5508PAG. Both components share identical pin configurations, electrical specifications, and package dimensions (64-TQFP 10x10). No circuit modifications are required for substitution.

Q: What is the difference between TAS5508PAG and TAS5508CPAG?

A: The primary difference is product status. The TAS5508PAG is obsolete, while the TAS5508CPAG is an active product currently manufactured by Texas Instruments. All electrical, functional, and package parameters are identical.

Q: Are there any packaging differences between these parts?

A: The TAS5508PAG is supplied in standard packaging, while the TAS5508CPAG is supplied in Tray packaging. Both use the same 64-TQFP (10x10) surface mount package. Tray packaging is standard for active production components.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TAS5508PAG and TAS5508CPAG are ROHS3 compliant, REACH unaffected, and carry MSL 4 (72 Hours) moisture sensitivity ratings. Regulatory compliance is equivalent.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: 8-channel modulator function, I2C and I2S interface support, 3V to 3.6V supply voltage, 32kHz to 192kHz frequency specification, 64-TQFP (10x10) package, and 0°C to 70°C operating temperature range.
