MCS1803GS-40-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The MCS1803GS-40-P is a 5V linear Hall-effect current sensor manufactured by Monolithic Power Systems Inc., designed for bidirectional AC/DC current measurement applications. This surface-mount device operates in the ±40A sensing range with ratiometric voltage output and is housed in an 8-SOIC package. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent functional performance across identical electrical and mechanical specifications.
