SCV2903DR2G Equivalent & Substitute Parts

Part Overview

The SCV2903DR2G is an 8-SOIC linear comparator manufactured by onsemi. This device is classified as obsolete and is no longer in active production. The SCV2903DR2G operates as a general-purpose comparator suitable for applications requiring dual-channel comparison functionality in 8-pin surface-mount packages.

Due to its obsolete status, locating new inventory of the SCV2903DR2G presents supply chain challenges. Identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary to maintain design continuity and ensure project timelines are not compromised by component unavailability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCV2903DR2G is determined by the following critical parameters:

Package Compatibility: The substitute part must be housed in an 8-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 operate as a general-purpose comparator with dual-channel capability, maintaining the same functional role within the circuit.

Electrical Specifications: The substitute must support the same supply voltage range, input offset voltage specifications, input bias current ratings, output current capabilities, quiescent current limits, and propagation delay characteristics as the original device.

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

Moisture Sensitivity: The substitute must have an MSL rating of 1 (Unlimited) to match the handling and storage requirements of the original device.

The primary substitute for the SCV2903DR2G is the NCV2903DR2G, which is an active product from onsemi with identical package specifications and compatible electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The NCV2903DR2G is the direct substitute for the obsolete SCV2903DR2G. Both devices share identical package specifications (8-SOIC), compliance certifications (ROHS3, REACH Unaffected), and moisture sensitivity ratings (MSL 1).

The NCV2903DR2G maintains active product status with substantial inventory availability (145,200 pcs), ensuring reliable supply chain access compared to the obsolete SCV2903DR2G (860 pcs remaining stock). The NCV2903DR2G carries automotive-grade qualification (AEC-Q100) and operates across the industrial temperature range (-40°C ~ 125°C), providing enhanced reliability for demanding applications.

Both devices are surface-mount components suitable for automated assembly processes. The electrical parameters of the NCV2903DR2G (supply voltage range 2V ~ 36V or ±1V ~ 18V, input offset voltage 7mV maximum, input bias current 0.25µA maximum, output current 16mA typical, and propagation delay 1.3µs maximum) establish the performance baseline for substitution compatibility.

Selection of the NCV2903DR2G eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing designs utilizing the SCV2903DR2G.
