SRC4382IPFBG4 Equivalent & Substitute Parts

Part Overview

The SRC4382IPFBG4 is a 2-channel audio sample rate converter manufactured by Texas Instruments, designed for digital audio interfacing applications. This integrated circuit operates across a frequency range of 4kHz to 216kHz and supports both I2C and SPI interfaces. The device is packaged in a 48-TQFP (7x7mm) surface mount configuration.

The SRC4382IPFBG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this audio processing component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SRC4382IPFBG4 is determined by strict equivalence across the following critical parameters:

• Identical base product number (SRC4382)
• Matching channel configuration (2 channels)
• Identical interface protocols (I2C, SPI)
• Matching voltage supply range (3V ~ 3.6V)
• Identical operating temperature range (-40°C ~ 85°C)
• Matching frequency specifications (4kHz ~ 216kHz)
• Identical package and pinout (48-TQFP, 7x7mm)
• Equivalent RoHS and environmental compliance

The SRC4382IPFB meets all substitution criteria and is classified as a manufacturer-recommended equivalent. The primary distinction between these parts is packaging format and product availability status.

Parameter Comparison

Engineering Selection Recommendations

The SRC4382IPFB is the manufacturer-recommended substitute for the discontinued SRC4382IPFBG4. Both parts share identical electrical specifications, thermal characteristics, and package geometry. The SRC4382IPFB maintains active product status with higher inventory availability (1622 Pcs in stock versus 744 Pcs for the original part).

Both parts carry equivalent compliance certifications: ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings. The only functional difference is the packaging format (Tray versus Tube), which does not affect component performance or PCB integration.

For new designs or production continuity, the SRC4382IPFB is the appropriate selection due to its active status and sustained manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are the SRC4382IPFBG4 and SRC4382IPFB electrically identical?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, including 2-channel configuration, I2C/SPI interface support, 3V to 3.6V supply voltage, -40°C to 85°C operating range, and 4kHz to 216kHz frequency specifications.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The SRC4382IPFBG4 is supplied in Tube packaging, while the SRC4382IPFB is supplied in Tray packaging. Both use the identical 48-TQFP (7x7mm) surface mount package.

Q: Can I use the SRC4382IPFB as a direct replacement on existing PCBs?

A: Yes. The SRC4382IPFB is a direct pin-for-pin and functional equivalent. No PCB modifications or design changes are required for substitution.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL 2 (1 Year) moisture sensitivity ratings.

Q: Why is the SRC4382IPFBG4 discontinued?

A: The SRC4382IPFBG4 has been discontinued at DiGi Electronics. The SRC4382IPFB remains in active production and is the recommended alternative for continued supply.

Q: What is the inventory status for the substitute part?

A: The SRC4382IPFB has 1622 Pcs of new original stock available, providing adequate supply for production requirements.
