SC324DR2G Equivalent & Substitute Parts

Part Overview

The SC324DR2G is a general-purpose operational amplifier manufactured by onsemi, housed in a 14-SOIC surface mount package. This device is classified as obsolete and is no longer in active production. Due to its obsolete status, sourcing new units from primary distribution channels is limited. Identifying functionally compatible substitute components is essential for design continuity, system maintenance, and production support where the SC324DR2G is specified in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC324DR2G is determined by the following critical parameters:

Package Compatibility: The substitute part must utilize the 14-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing printed circuit board layouts and assembly processes.

Functional Classification: The substitute must be classified as a general-purpose operational amplifier to maintain functional equivalence within the application circuit.

Manufacturer Alignment: onsemi manufacture of both the original and substitute part ensures consistency in design specifications, quality standards, and long-term availability.

Compliance Requirements: The substitute part must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory and environmental requirements equivalent to the original component.

Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures no additional handling or storage constraints are introduced during component substitution.

The NCV2902DR2G meets all substitution criteria and is actively produced, providing reliable long-term availability for applications requiring SC324DR2G replacement.

Parameter Comparison

Engineering Selection Recommendations

The NCV2902DR2G is the designated substitute for the obsolete SC324DR2G based on the following engineering criteria:

Package Equivalence: Both components utilize identical 14-SOIC surface mount packaging, ensuring direct compatibility with existing PCB designs without layout modifications.

Regulatory Compliance: The NCV2902DR2G maintains ROHS3 compliance and REACH unaffected status, satisfying the same environmental and regulatory requirements as the original SC324DR2G.

Active Production Status: The NCV2902DR2G is actively manufactured by onsemi with substantial inventory availability (77,700 units), ensuring reliable long-term sourcing compared to the obsolete SC324DR2G.

Manufacturer Consistency: Both components are produced by onsemi, maintaining design philosophy, quality standards, and technical support continuity.

Moisture Handling: Identical MSL rating of 1 (Unlimited) eliminates additional moisture sensitivity considerations during component procurement and assembly.

Selection of the NCV2902DR2G for SC324DR2G replacement is supported by package compatibility, regulatory alignment, and active production status.

Frequently Asked Questions (FAQ)
