MCS1806GS-5-50-P Equivalent & Substitute Parts

Part Overview

The MCS1806GS-5-50-P is a 3KVRMS isolated Hall-effect current sensor manufactured by Monolithic Power Systems Inc. This component is designed for AC/DC current measurement applications requiring differential, bidirectional sensing capability. The device operates as a ratiometric voltage output sensor with ±50A sensing range and is housed in an 8-SOIC surface mount package.

The MCS1806GS-5-50-P maintains Active product status and is ROHS3 compliant. Identifying equivalent substitute parts is necessary for supply chain continuity, inventory optimization, and procurement flexibility when the primary part number becomes unavailable or when alternative packaging formats are required.

Substitute Part Grouping Explanation

Substitution eligibility for the MCS1806GS-5-50-P is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Sensor type: Hall Effect, Differential
• Current sensing range: ±50A
• Output configuration: Ratiometric, Voltage
• Sensitivity: 40mV/A
• Frequency response: 100kHz
• Linearity: ±0.5%
• Accuracy: ±2.5%
• Supply voltage range: 4.5V ~ 5.5V
• Response time: 5µs
• Maximum supply current: 10.5mA
• Operating temperature range: -40°C ~ 125°C (TJ)
• Polarization: Bidirectional
• Measurement capability: AC/DC

Mechanical Equivalence Criteria:

• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
