TAS5504PAG Equivalent & Substitute Parts

Part Overview

The TAS5504PAG is a 4-channel audio modulator IC in 64-TQFP surface mount packaging manufactured by Texas Instruments. This device 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 TAS5504PAG is classified as "Not For New Designs," indicating it has reached end-of-life status. For new design implementations or when inventory constraints exist, identifying functionally compatible substitute components is essential for project continuity and supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5504PAG is determined by the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 64-TQFP (10x10) — ensures physical and electrical compatibility with existing PCB layouts
• Mounting Type: Surface Mount — maintains assembly process compatibility
• Interface: I2C, I2S — preserves communication protocol compatibility
• Voltage - Supply: 3V ~ 3.6V — ensures power supply compatibility
• Operating Temperature: 0°C ~ 70°C (TA) — maintains thermal operating range
• Specifications: 32kHz ~ 192kHz — supports required audio frequency range
• RoHS Status: ROHS3 Compliant — maintains regulatory compliance
• Moisture Sensitivity Level (MSL): 4 (72 Hours) — ensures equivalent handling and storage requirements

Flexible Parameters:

• Number of Channels: May exceed the original 4-channel specification, provided all other parameters remain compatible
• Product Status: Active status is preferred for new designs, though not a strict substitution barrier

Parameter Comparison

Engineering Selection Recommendations

The TAS5508CPAG is a valid substitute for the TAS5504PAG based on parameter alignment. Both devices share identical electrical specifications, package geometry, interface protocols, and regulatory compliance status. The TAS5508CPAG provides 8 channels of modulation capability compared to the 4-channel configuration of the TAS5504PAG, representing a functional superset. The TAS5508CPAG maintains Active product status with Texas Instruments, ensuring continued availability and support for new design implementations. Both components comply with ROHS3 regulations and maintain equivalent moisture sensitivity classifications, supporting identical handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the TAS5508CPAG directly replace the TAS5504PAG in existing designs?

A: Yes, the TAS5508CPAG is physically and electrically compatible with the TAS5504PAG. Both devices use identical 64-TQFP (10x10) packaging, support the same I2C and I2S interfaces, operate within the same voltage and temperature ranges, and maintain equivalent regulatory compliance. The primary difference is the increased channel count (8 versus 4), which does not prevent substitution.

Q: What is the significance of the increased channel count in the TAS5508CPAG?

A: The TAS5508CPAG provides 8 modulation channels instead of 4. In applications requiring only 4 channels, the additional channels remain unused but do not compromise functionality. The device will operate correctly with partial channel utilization.

Q: Are there any handling or storage differences between these parts?

A: No. Both the TAS5504PAG and TAS5508CPAG share identical Moisture Sensitivity Level (MSL) ratings of 4 (72 Hours), requiring equivalent handling, storage, and reflow procedures.

Q: Why is the TAS5504PAG marked "Not For New Designs"?

A: This designation indicates the TAS5504PAG has reached end-of-life status with Texas Instruments. The TAS5508CPAG, with Active product status, is the recommended component for new design implementations.

Q: Are the I2C and I2S interface protocols identical between these devices?

A: Yes. Both the TAS5504PAG and TAS5508CPAG support I2C and I2S interfaces with identical specifications, ensuring protocol-level compatibility.

Q: Do both parts comply with the same regulatory standards?

A: Yes. Both devices are ROHS3 Compliant and REACH Unaffected, maintaining identical regulatory compliance profiles.
