Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SRC4382IPFBT is determined by strict alignment across the following critical parameters:

• Functional equivalence: Both parts must perform 2-channel audio sample rate conversion
• Interface compatibility: Both parts must support I2C and SPI communication protocols
• Electrical specifications: Supply voltage range (3V ~ 3.6V) and operating temperature range (-40°C ~ 85°C) must be identical
• Frequency range: Audio processing capability across 4kHz ~ 216kHz must be maintained
• Package compatibility: 48-TQFP (7x7) surface mount package ensures PCB layout compatibility
• Regulatory compliance: RoHS3 compliance and REACH unaffected status must be maintained

The SRC4382IPFB meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The SRC4382IPFB is the direct substitute for the obsolete SRC4382IPFBT. Both parts are manufactured by Texas Instruments and maintain identical electrical, mechanical, and regulatory specifications. The primary distinction is product status: the SRC4382IPFBT is obsolete while the SRC4382IPFB is active and currently in production.

For new designs and ongoing system support, the SRC4382IPFB is the appropriate selection. Both parts satisfy ROHS3 compliance requirements and maintain REACH unaffected status, ensuring regulatory alignment for industrial and consumer audio applications.

Frequently Asked Questions (FAQ)

Q: Can the SRC4382IPFB directly replace the SRC4382IPFBT in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The SRC4382IPFB operates across the same voltage range (3V ~ 3.6V), temperature range (-40°C ~ 85°C), and frequency specifications (4kHz ~ 216kHz). Both use the 48-TQFP (7x7) package, requiring no PCB modifications.

Q: What is the difference between the SRC4382IPFBT and SRC4382IPFB?

A: The primary difference is packaging format and product status. The SRC4382IPFBT is supplied in tape format and is obsolete. The SRC4382IPFB is supplied in tray format and is active. All functional and electrical parameters are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level is identical at MSL 2 (1 Year) for both variants.

Q: What applications are these parts suitable for?

A: Both parts are designed for digital audio interfacing applications requiring 2-channel sample rate conversion across the 4kHz to 216kHz frequency range. I2C and SPI interface support enables integration into audio processing systems, digital audio workstations, and consumer audio equipment.

Q: Is the 48-TQFP package the only available option?

A: Based on the provided specifications, the 48-TQFP (7x7) surface mount package is the standard package for both the SRC4382IPFBT and SRC4382IPFB.
