TAS5508CPAGR Equivalent & Substitute Parts

Part Overview

The TAS5508CPAGR is an 8-channel audio modulator IC manufactured by Texas Instruments in a 64-TQFP surface mount package. This component is designed for digital audio interfacing applications, supporting I2C and I2S interfaces with a supply voltage range of 3V to 3.6V and operating temperature range of 0°C to 70°C. The part maintains Active product status with full ROHS3 compliance and REACH unaffected classification.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative channel configurations or operating temperature ranges within the TAS550x modulator family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility within the TAS550x family is determined by the following parameters:

Primary Substitution Criteria:

• Identical package type: 64-TQFP (10x10) surface mount
• Matching interface protocols: I2C and I2S support
• Compatible supply voltage range: 3V to 3.6V
• Identical audio frequency specifications: 32kHz to 192kHz
• Equivalent moisture sensitivity level: MSL 4 (72 Hours)
• ROHS3 compliance and REACH unaffected status

Secondary Consideration:

• Number of channels (8-channel primary; 4-channel available as alternative)
• Operating temperature range (standard 0°C to 70°C; extended -20°C to 70°C available)
• Product status (Active preferred; Not For New Designs acceptable for legacy support; Last Time Buy indicates limited availability)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Preferred): TAS5508BPAGR maintains identical electrical and mechanical specifications to TAS5508CPAGR with 8-channel configuration, matching operating temperature range, and equivalent compliance certifications. Although marked Not For New Designs, this part provides direct functional equivalence for existing designs requiring component replacement.

Extended Temperature Alternative: TAS5518PAGR offers 8-channel functionality with extended operating temperature range (-20°C to 70°C) suitable for applications requiring low-temperature performance. This part is electrically compatible but carries Not For New Designs status.

Channel-Reduced Alternative: TAS5504PAGR provides 4-channel modulation in identical package with matching electrical specifications. Selection of this part requires design confirmation that 4-channel operation satisfies application requirements.

End-of-Life Consideration: TAS5508PAGR carries Last Time Buy status, indicating limited remaining inventory. This part is suitable only for immediate replacement needs where inventory availability is confirmed.

Frequently Asked Questions (FAQ)

Q: Can TAS5508BPAGR directly replace TAS5508CPAGR in existing designs? A: Yes. Both parts share identical channel count (8), operating temperature range (0°C to 70°C), supply voltage (3V to 3.6V), interface protocols (I2C, I2S), and package configuration (64-TQFP). Electrical and mechanical compatibility is complete.

Q: What is the difference between TAS5508CPAGR and TAS5518PAGR? A: The primary difference is operating temperature range. TAS5518PAGR extends to -20°C minimum, while TAS5508CPAGR operates from 0°C minimum. Both maintain 8-channel configuration and identical package specifications. Selection depends on application temperature requirements.

Q: Can TAS5504PAGR substitute for TAS5508CPAGR? A: TAS5504PAGR is a 4-channel variant in the same package. Substitution is possible only if the application design can operate with reduced channel count. Electrical specifications and package dimensions remain compatible.

Q: Why is TAS5508PAGR marked Last Time Buy? A: Last Time Buy status indicates the manufacturer has announced end-of-production. Remaining inventory is limited. This part should be selected only when immediate replacement is required and inventory availability is confirmed.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the primary part's regulatory certifications.

Q: What packaging format is available for these parts? A: All substitute parts are supplied in Tape & Reel (TR) format suitable for automated assembly processes.
