MCS1803GS-10-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The MCS1803GS-10-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 ±10A 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 component availability requires alternative sourcing while maintaining identical electrical and mechanical specifications. The MCS1803GS-10-P and its substitute share all critical performance parameters, enabling direct replacement in circuit designs without modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for Hall-effect current sensors is determined by strict equivalence across electrical performance and mechanical compatibility parameters. The MCS1803GS-10-P and its substitute must satisfy the following criteria:

Electrical Performance Parameters:

• Identical current sensing range (±10A)
• Matching sensitivity specification (200mV/A)
• Equivalent frequency response (100kHz)
• Same linearity tolerance (±0.5%)
• Identical accuracy specification (±2.5%)
• Matching supply voltage range (4.5V ~ 5.5V)
• Equivalent response time (5µs)
• Identical maximum supply current (10.5mA)
• Same operating temperature range (-40°C ~ 125°C)

Mechanical & Packaging Parameters:

• Identical package type (8-SOIC, 0.154", 3.90mm Width)
• Surface-mount configuration
• Single-channel configuration
• Bidirectional polarization

Compliance & Regulatory Parameters:

• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• Active product status

The substitute part MCS1803GS-10-Z meets all specified criteria and is classified as a parametric equivalent.
