TAS5026APAG Equivalent & Substitute Parts
Part Overview
The TAS5026APAG is a 6-channel audio modulator IC manufactured by Texas Instruments, designed for digital audio interfacing applications. It operates within the PurePath Digital™ series and is packaged in a 64-TQFP (10x10) surface mount configuration. The device is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. Substitute parts must maintain electrical compatibility across supply voltage, operating temperature, interface protocols, and audio frequency specifications while accommodating the same physical package footprint.

Substitute Part Grouping Explanation
Substitute parts for the TAS5026APAG are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:
- Package Compatibility: 64-TQFP (10x10) surface mount configuration
- Supply Voltage Range: 3V ~ 3.6V operation
- Operating Temperature Range: 0°C ~ 70°C (TA)
- Interface Protocols: I2C and I2S support
- Audio Frequency Support: 32kHz ~ 192kHz capability
- Compliance Standards: ROHS3 Compliant, REACH Unaffected
- Moisture Sensitivity: MSL 4 (72 Hours)
The TAS5508CPAGR qualifies as a manufacturer-recommended substitute. While it features 8 channels compared to the 6-channel configuration of the TAS5026APAG, it maintains full electrical compatibility across all critical parameters and operates within the same physical package footprint. The increased channel count does not preclude substitution in applications where the additional channels can be left unused or repurposed.

Engineering Selection Recommendations
The TAS5508CPAGR is the manufacturer-recommended substitute for the obsolete TAS5026APAG. Both devices maintain identical electrical specifications across supply voltage, operating temperature range, interface protocols, and audio frequency support. The physical package footprint is identical, enabling direct PCB-level substitution without layout modifications.
The TAS5508CPAGR carries Active product status, ensuring continued availability and manufacturing support. Both parts maintain equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected, and identical moisture sensitivity levels. The increased channel count (8 versus 6) does not introduce incompatibility; unused channels can be configured as required by the application firmware.
Frequently Asked Questions (FAQ)
Q: Can the TAS5508CPAGR directly replace the TAS5026APAG on existing PCBs?
A: Yes. Both devices use the 64-TQFP (10x10) package with identical pin configurations for the supported interfaces (I2C, I2S). No PCB layout modifications are required.
Q: What is the significance of the increased channel count in the TAS5508CPAGR?
A: The TAS5508CPAGR provides 8 modulation channels versus 6 in the TAS5026APAG. In applications requiring only 6 channels, the additional 2 channels remain available for future expansion or can be disabled through firmware configuration.
Q: Are the supply voltage and operating temperature ranges identical?
A: Yes. Both parts operate at 3V ~ 3.6V supply voltage and 0°C ~ 70°C operating temperature range, ensuring thermal and electrical compatibility in equivalent system designs.
Q: Do both parts support the same audio frequency range?
A: Yes. Both the TAS5026APAG and TAS5508CPAGR support audio frequencies from 32kHz to 192kHz, maintaining full compatibility for digital audio interfacing applications.
Q: What is the product status difference, and does it affect substitution?
A: The TAS5026APAG is classified as Obsolete, while the TAS5508CPAGR is Active. The Active status of the substitute ensures continued manufacturing availability and long-term supply chain reliability.
Q: Are moisture sensitivity and compliance certifications equivalent?
A: Yes. Both parts carry MSL 4 (72 Hours) moisture sensitivity levels and maintain identical compliance: ROHS3 Compliant and REACH Unaffected.
