TAS5076PFC Equivalent & Substitute Parts

Part Overview

The TAS5076PFC is a 6-channel audio modulator IC manufactured by Texas Instruments, designed for digital audio interfacing applications. It operates as a surface-mount component in an 80-TQFP package and supports audio sampling rates from 32kHz to 192kHz. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TAS5076PFC are identified based on the following critical parameters: manufacturer (Texas Instruments), functional category (audio modulator), application domain (digital audio interfacing), interface protocols (I2C, I2S), supply voltage range (3V ~ 3.6V), and audio frequency specifications (32kHz ~ 192kHz). All substitute parts maintain compatibility with these core electrical and functional requirements.

Two substitute parts are available:

TAS5086DBT maintains identical channel count (6 channels), operating temperature range (0°C ~ 70°C), and all electrical specifications. The primary difference is packaging format: 38-TSSOP versus 80-TQFP. This part is currently active in production.

TAS5558DCA provides an alternative with expanded channel capacity (8 channels) and extended operating temperature range (0°C ~ 85°C). The package format is 56-HTSSOP. This part is also currently active in production.

Parameter Comparison

Engineering Selection Recommendations

TAS5086DBT is the primary substitute for direct replacement applications. It maintains identical channel count and operating temperature specifications while offering active product status and improved moisture sensitivity rating (MSL 2 versus MSL 4). The 38-TSSOP package requires PCB layout modification compared to the original 80-TQFP footprint. This part is suitable for applications requiring 6-channel audio modulation within the 0°C to 70°C operating range.

TAS5558DCA is appropriate for applications that can accommodate 8-channel capability and extended operating temperature range (0°C to 85°C). The 56-HTSSOP package also requires PCB layout redesign. This option provides additional thermal margin and channel capacity for enhanced system flexibility.

Both substitute parts maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can TAS5086DBT directly replace TAS5076PFC without firmware changes? A: Both parts share identical channel count (6), interface protocols (I2C, I2S), voltage supply range (3V ~ 3.6V), operating temperature (0°C ~ 70°C), and audio specifications (32kHz ~ 192kHz). Firmware compatibility depends on device-specific register mapping and control sequences, which must be verified against datasheets. PCB layout modification is required due to package format change from 80-TQFP to 38-TSSOP.

Q: What are the package footprint differences? A: TAS5076PFC uses 80-TQFP (12x12mm), TAS5086DBT uses 38-TSSOP (4.40mm width), and TAS5558DCA uses 56-HTSSOP (6.10mm width). Each package requires distinct PCB land patterns and routing considerations.

Q: Is TAS5558DCA suitable if my application only requires 6 channels? A: Yes. TAS5558DCA provides 8-channel capability, so 6-channel applications can utilize this part. The additional channels remain unused. The extended operating temperature range (0°C ~ 85°C) provides thermal margin beyond the original specification (0°C ~ 70°C).

Q: What is the moisture sensitivity impact of substitution? A: TAS5076PFC has MSL 4 (72 hours), TAS5086DBT has MSL 2 (1 year), and TAS5558DCA has MSL 3 (168 hours). Lower MSL ratings indicate better moisture tolerance and reduced risk during storage and assembly processes.

Q: Are all substitute parts ROHS3 and REACH compliant? A: Yes. TAS5076PFC, TAS5086DBT, and TAS5558DCA are all ROHS3 compliant and REACH unaffected, ensuring regulatory compatibility across all options.
