TAS5508PAGG4 Equivalent & Substitute Parts

Part Overview

The TAS5508PAGG4 is an 8-channel audio modulator IC manufactured by Texas Instruments, designed for digital audio interfacing applications. It operates across a frequency range of 32kHz to 192kHz and is housed in a 64-TQFP (10x10) surface mount package. The device is currently classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5508PAGG4 is determined by strict equivalence across the following critical parameters:

• Functional equivalence: 8-channel audio modulator with identical I2C and I2S interface support
• Electrical compatibility: 3V ~ 3.6V supply voltage range and 0°C ~ 70°C operating temperature
• Frequency specification: 32kHz ~ 192kHz audio bandwidth
• Physical compatibility: 64-TQFP (10x10) surface mount package
• Regulatory compliance: ROHS3 compliance and identical moisture sensitivity classification

The substitute parts TAS5508PAGR and TAS5508CPAG meet all these criteria. Differences exist only in packaging format (Tape & Reel versus Tray) and product lifecycle status, which do not affect functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

TAS5508CPAG is the primary recommended substitute for new designs and ongoing production. This part maintains Active product status with Texas Instruments, ensuring long-term availability and continued manufacturer support. It is supplied in Tray packaging and carries identical electrical and functional specifications to the obsolete TAS5508PAGG4.

TAS5508PAGR serves as an alternative substitute with equivalent technical specifications. This part is classified as Last Time Buy, indicating limited future availability. It is supplied in Tape & Reel format, suitable for automated assembly processes where this packaging format is preferred.

Both substitutes are ROHS3 compliant and maintain identical moisture sensitivity classification, ensuring compatibility with existing assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can TAS5508CPAG directly replace TAS5508PAGG4 in existing designs?

A: Yes. Both parts are functionally and electrically identical across all specified parameters: 8-channel audio modulation, I2C/I2S interface, 3V ~ 3.6V supply, 0°C ~ 70°C operating range, 32kHz ~ 192kHz frequency support, and 64-TQFP package. The only difference is packaging format (Tray versus Tube) and product lifecycle status.

Q: What is the difference between TAS5508PAGR and TAS5508CPAG?

A: Both parts are electrically and functionally identical. The primary differences are packaging format (Tape & Reel versus Tray) and product status (Last Time Buy versus Active). Selection depends on assembly process requirements and long-term availability needs.

Q: Why is TAS5508PAGG4 classified as Obsolete?

A: The TAS5508PAGG4 has reached end-of-life status with Texas Instruments. Equivalent alternatives with Active or Last Time Buy status are available to support continued system requirements.

Q: Are there any compliance differences between the substitute parts?

A: No. All three parts carry identical ROHS3 compliance, moisture sensitivity level 4 (72 Hours), and regulatory certifications. They are fully interchangeable from a compliance perspective.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tube, Tape & Reel, or Tray) affects only handling, storage, and assembly logistics. Electrical and functional performance is identical across all three parts.
