MCS1802GS-20-Z Equivalent & Substitute Parts

Part Overview

The MCS1802GS-20-Z is a 3.3V linear Hall-effect current sensor manufactured by Monolithic Power Systems Inc. This component functions as a bidirectional current sensor capable of measuring AC/DC currents in the ±20A range with ratiometric voltage output. The device is housed in an 8-SOIC surface mount package and is actively produced. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity while maintaining identical functional performance.

Substitute Part Grouping Explanation

Substitution of the MCS1802GS-20-Z is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part MCS1802GS-20-P shares identical specifications in the following key areas:

• Sensor Technology: Hall Effect topology with bidirectional current measurement capability
• Current Measurement Range: ±20A full-scale sensing
• Output Characteristics: Ratiometric voltage output with 66mV/A sensitivity
• Electrical Performance: Identical linearity (±0.5%), accuracy (±2.5%), frequency response (100kHz), and response time (5µs)
• Supply Voltage: 3V to 3.6V operating range
• Thermal Performance: -40°C to 125°C junction temperature range
• Package Specification: 8-SOIC (0.154", 3.90mm Width) surface mount configuration
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1 rating

The only distinction between these parts is the packaging format designation (tape & reel suffix), which does not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MCS1802GS-20-Z and MCS1802GS-20-P are active production components from Monolithic Power Systems Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on packaging and supply availability rather than electrical or mechanical performance differences.

The MCS1802GS-20-Z is supplied in tape & reel format with 2076 units currently in stock. The MCS1802GS-20-P is also supplied in tape & reel format with 1206 units currently in stock. Both parts are suitable for production assembly processes requiring surface mount components in 8-SOIC packages.

For applications requiring ±20A bidirectional current sensing with 3.3V supply operation, either part number provides identical electrical performance, thermal characteristics, and regulatory compliance. Selection should be based on inventory availability, lead time requirements, and supply chain logistics.

Frequently Asked Questions (FAQ)
