SA575DR2G Equivalent & Substitute Parts

Part Overview

The SA575DR2G is a 2-channel audio compandor IC manufactured by onsemi, designed for consumer audio and telecommunication system applications. This device operates across a 3V to 7V supply voltage range and is housed in a 20-SOIC surface mount package with a width of 7.50mm.

The SA575DR2G carries an Obsolete product status. As this component is no longer in active production, identifying functionally equivalent substitute parts is essential for design continuity, system maintenance, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA575DR2G is determined by the following critical parameters:

• Base Product Number: Both parts share the SA575 base designation, confirming functional equivalence at the silicon level
• Function & Channel Configuration: Both maintain 2-channel compandor functionality with analog interface
• Electrical Specifications: Identical supply voltage range (3V ~ 7V) and operating temperature range (-40°C ~ 85°C)
• Compliance & Certifications: Both are ROHS3 compliant and REACH unaffected, meeting regulatory requirements
• Mounting Technology: Both use surface mount technology, enabling PCB-level compatibility

The primary distinction between the main part and its substitute lies in the package form factor and product lifecycle status, not in electrical performance or functional capability.

Parameter Comparison

Engineering Selection Recommendations

SA575DTBR2G is the direct substitute for SA575DR2G based on the following engineering criteria:

• Functional Equivalence: Identical compandor architecture, channel count, and electrical specifications ensure drop-in compatibility at the circuit level
• Active Product Status: The SA575DTBR2G maintains Active product status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts meet ROHS3 and REACH requirements, maintaining compliance with current environmental and safety standards
• Package Consideration: The SA575DTBR2G uses a 20-TSSOP package (4.40mm width) versus the 20-SOIC package (7.50mm width) of the original part. PCB layout modification is required to accommodate the smaller footprint
• Moisture Sensitivity: The SA575DTBR2G offers improved moisture handling (MSL 1 vs. MSL 3), reducing storage and handling constraints

Frequently Asked Questions (FAQ)

Q: Can SA575DTBR2G directly replace SA575DR2G without circuit modifications?

A: Electrical and functional compatibility is complete. However, the package form factor differs (20-TSSOP vs. 20-SOIC), requiring PCB layout redesign to accommodate the smaller 4.40mm width footprint.
