IRS20955CD Equivalent & Substitute Parts

Part Overview

The IRS20955CD is a Class D audio driver amplifier IC manufactured by Infineon Technologies, housed in a 16-SOIC package. This component is classified as an obsolete product and is no longer in active production. The IRS20955CD was designed for audio amplification applications requiring integrated driver functionality in a compact surface-mount form factor.

Due to its obsolete status, sourcing new units from primary distribution channels is limited. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently utilizing this component. Substitute parts must maintain functional equivalence in package type, electrical characteristics, and application compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRS20955CD is determined by the following critical parameters:

Package Compatibility: The substitute part must utilize the 16-SOIC (0.154", 3.90mm Width) surface-mount package to ensure mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Functional Classification: The substitute must be classified as a Class D amplifier IC to maintain equivalent operational characteristics and performance envelope.

Manufacturer Consistency: Infineon Technologies manufactured the original part; substitute parts from the same manufacturer ensure design continuity and support consistency.

Electrical Specifications: Supply voltage range, output configuration, and protection features must align with the original design requirements.

Compliance & Certification: Substitute parts must maintain equivalent or superior compliance status (REACH, RoHS) to satisfy regulatory requirements.

The IRS20957STRPBF meets all substitution criteria as an active-status equivalent from Infineon Technologies.
