Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC2903DR2G is determined by the following critical parameters:

Package Compatibility: The substitute component must utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Manufacturer Alignment: onsemi manufacture of both the original and substitute component ensures consistent quality standards, supply chain reliability, and technical support continuity.

Compliance Requirements: Both components must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory and environmental requirements for the target application.

Functional Classification: The substitute must operate within the general-purpose linear amplifier or comparator category, maintaining compatibility with typical signal conditioning and amplification circuit topologies.

The LM2903DR2G qualifies as a direct substitute based on these parameters, despite functional differences between amplifier and comparator architectures. Both devices share identical package specifications, manufacturer origin, and compliance certifications.
