TAS5010IPFBG4 Equivalent & Substitute Parts

Part Overview

The TAS5010IPFBG4 is a 2-channel audio signal processor manufactured by Texas Instruments, housed in a 48-TQFP (7x7) surface mount package. This device operates within the 3V to 3.6V supply voltage range and supports DSP and I2S interfaces for audio applications. The product is classified as obsolete, making identification of functionally compatible alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAS5010IPFBG4 are identified based on the following critical parameters that determine functional compatibility:

Allowable Substitution Criteria:

• Voltage supply range: 3V ~ 3.6V (must match or encompass)
• Interface support: I2S compatibility (mandatory)
• Mounting type: Surface mount
• RoHS3 compliance
• Manufacturer: Texas Instruments (PurePath Digital™ series)

The substitute parts listed—TAS5086DBTR, TAS5558DCAR, and TAS5086DBT—all meet these core electrical and compliance requirements. However, they differ in channel count (6 or 8 channels versus 2 channels), package type, and operating temperature ranges. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain ROHS3 compliance and active product status, providing long-term availability and regulatory alignment. Selection between TAS5086DBTR, TAS5558DCAR, and TAS5086DBT depends on application-specific requirements:

TAS5086DBTR and TAS5086DBT share identical electrical specifications and channel count (6 channels). The primary distinction is packaging format: TAS5086DBTR is supplied in Cut Tape (CT) & Digi-Reel® format, while TAS5086DBT is supplied in Tube format. Both support the 0°C to 70°C operating temperature range.

TAS5558DCAR provides 8-channel capability with an extended operating temperature range of 0°C to 85°C, matching the upper temperature limit of the original TAS5010IPFBG4. This part is housed in a 56-PowerTFSOP package, which is physically larger than the 38-TFSOP packages of the TAS5086 variants.

The TAS5010IPFBG4 operates from -40°C to 85°C. If the application requires the full -40°C lower temperature limit, none of the listed substitutes maintain this specification. Verification of actual operating temperature requirements is necessary before final selection.

Frequently Asked Questions (FAQ)

Q: Can TAS5086DBTR or TAS5086DBT directly replace TAS5010IPFBG4 in existing designs?

A: Direct replacement requires PCB layout modification. The TAS5086 variants use 38-TFSOP packages with different pin configurations compared to the 48-TQFP package of the TAS5010IPFBG4. Pin mapping and signal routing must be re-evaluated. Additionally, the 6-channel architecture differs from the 2-channel design of the original part.

Q: What is the difference between TAS5086DBTR and TAS5086DBT?

A: Both parts are electrically identical with matching specifications. The difference is in packaging and supply format: TAS5086DBTR is supplied in Cut Tape (CT) & Digi-Reel® format for automated assembly, while TAS5086DBT is supplied in Tube format for manual handling or lower-volume applications.

Q: Does TAS5558DCAR support the full operating temperature range of TAS5010IPFBG4?

A: TAS5558DCAR operates from 0°C to 85°C, covering the upper temperature limit of the original part but not the -40°C lower limit. If applications require operation below 0°C, TAS5558DCAR is not suitable.

Q: Are all substitute parts I2S compatible?

A: Yes. All three substitute parts support I2S interface, which is present in the original TAS5010IPFBG4. However, the TAS5086 and TAS5558 variants also support I2C, providing additional interface flexibility not available in the original part.

Q: What compliance certifications apply to these substitute parts?

A: All parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the TAS5010IPFBG4. All parts carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
