SC258DR2G Equivalent & Substitute Parts

Part Overview

The SC258DR2G is a linear operational amplifier integrated circuit manufactured by onsemi, housed in an 8-SOIC surface mount package. This device functions as an amplifier circuit and is classified as obsolete. Due to its obsolete product status, locating original inventory may present supply chain challenges. Identifying equivalent and substitute parts ensures design continuity and maintains access to functionally compatible components for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC258DR2G is based on strict alignment of mechanical and electrical compatibility parameters. The primary substitution criterion is the identical package configuration: 8-SOIC (0.154", 3.90mm Width) with surface mount mounting type. Both the main part and substitute must maintain compliance with RoHS3 and REACH regulations to ensure regulatory equivalence. The substitute part must be manufactured by onsemi to preserve design validation and supply chain consistency. The LM258DR2G meets all these criteria and is classified as an active product, providing superior long-term availability compared to the obsolete SC258DR2G.

Parameter Comparison

Engineering Selection Recommendations

The LM258DR2G is the direct substitute for the SC258DR2G based on identical mechanical packaging, regulatory compliance, and manufacturer consistency. The LM258DR2G maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for applications requiring these certifications. The transition from obsolete to active product status provides significant supply chain advantages, with substantially higher inventory availability (505,200 pieces in stock versus 782 pieces for the original part). Both components share identical ECCN and HTSUS classifications, maintaining export and tariff compliance. The 8-SOIC package geometry and surface mount configuration are identical, permitting direct PCB layout compatibility without redesign. Selection of the LM258DR2G eliminates obsolescence risk while preserving all compliance and mechanical requirements of the original design.

Frequently Asked Questions (FAQ)

Q: Can the LM258DR2G be used as a direct replacement for the SC258DR2G on existing PCBs?

A: Yes. Both components share identical 8-SOIC package dimensions (0.154", 3.90mm width) and surface mount configuration. No PCB layout modifications are required for substitution.

Q: Are there regulatory compliance differences between these parts?

A: No. Both the SC258DR2G and LM258DR2G maintain identical RoHS3 compliance, REACH unaffected status, ECCN classification (EAR99), and HTSUS code (8542.33.0001). Regulatory requirements are fully satisfied by either component.

Q: What is the primary advantage of selecting the LM258DR2G over the SC258DR2G?

A: The LM258DR2G is classified as an active product with significantly higher inventory availability (505,200 pieces in stock). The SC258DR2G is obsolete, presenting supply chain risk and potential long-term unavailability. The LM258DR2G ensures sustained component access for production and support.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the SC258DR2G and LM258DR2G are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Is the supplier device package identical for both parts?

A: Yes. Both components use the 8-SOIC supplier device package designation, confirming mechanical and electrical pin compatibility.
