TAS5518PAGG4 Equivalent & Substitute Parts

Part Overview

The TAS5518PAGG4 is an 8-channel audio modulator IC in 64-TQFP packaging manufactured by Texas Instruments. This device interfaces digital audio signals via I2C and I2S protocols, supporting sample rates from 32kHz to 192kHz. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5518PAGG4 is determined by the following critical parameters:

• 8-channel audio modulation function with I2C and I2S interface support
• 64-TQFP (10x10) package for mechanical and PCB layout compatibility
• 3V ~ 3.6V supply voltage range for power distribution compatibility
• 32kHz ~ 192kHz sample rate capability for audio specification alignment
• Surface mount technology for assembly process compatibility
• ROHS3 compliance and MSL 4 rating for environmental and handling requirements

Substitute parts must maintain these core parameters to ensure direct functional replacement without circuit redesign or PCB modification.

Parameter Comparison

Engineering Selection Recommendations

TAS5518PAG is a direct functional equivalent with identical electrical specifications and packaging. However, its "Not For New Designs" status indicates limited long-term availability and support from the manufacturer.

TAS5508CPAG is the recommended substitute for new applications and ongoing production. This part maintains all critical electrical parameters, package specifications, and interface requirements. The operating temperature range is narrower (0°C ~ 70°C versus -20°C ~ 70°C), which is acceptable for standard commercial applications. The part carries "Active" product status, ensuring continued availability, manufacturing support, and compliance updates from Texas Instruments.

For applications requiring the extended -20°C lower temperature limit, TAS5518PAG remains functionally compatible despite its discontinued status.

Frequently Asked Questions (FAQ)

Q: Can TAS5508CPAG replace TAS5518PAGG4 in all applications?

A: TAS5508CPAG is electrically and mechanically compatible for applications operating within 0°C to 70°C. Applications requiring operation below 0°C must use TAS5518PAG or verify that the narrower temperature range is acceptable for the specific use case.

Q: Are there packaging differences between these parts?

A: All three parts use 64-TQFP (10x10) surface mount packaging. TAS5518PAGG4 ships in tube packaging, while TAS5518PAG and TAS5508CPAG ship in tray packaging. This difference does not affect electrical performance or PCB compatibility.

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

A: "Discontinued at DiGi Electronics" indicates the TAS5518PAGG4 is no longer stocked by this distributor. "Not For New Designs" indicates TAS5518PAG has limited future support. "Active" status for TAS5508CPAG confirms ongoing manufacturing, quality assurance, and long-term availability from Texas Instruments.

Q: Do all three parts meet the same compliance requirements?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 4 moisture sensitivity ratings. Compliance certifications are equivalent across all substitute options.

Q: What is the inventory availability status?

A: TAS5508CPAG has the highest inventory availability (108,200 pcs), followed by TAS5518PAG (1,900 pcs). TAS5518PAGG4 availability is limited (731 pcs). For production planning, TAS5508CPAG is the most reliable choice.
