• Sensor type: Hall Effect, Differential
• Output configuration: Ratiometric, Voltage
• Sensitivity: 66mV/A
• Frequency response: 100kHz
• Linearity: ±0.5%
• Accuracy: ±2.5%
• Supply voltage range: 3V ~ 3.6V
• Response time: 5µs
• Maximum supply current: 10.5mA
• Operating temperature range: -40°C ~ 125°C (TJ)
• Polarization: Bidirectional
• Number of channels: 1

Mechanical Parameters (Must Match Exactly):

• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Packaging format: Tape & Reel (TR)

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The MCS1806GS-3-20-Z is identified as a parametric equivalent substitute for the MCS1806GS-3-20-P.

Parameter Comparison

Engineering Selection Recommendations

The MCS1806GS-3-20-Z is a direct parametric equivalent to the MCS1806GS-3-20-P. Both parts are manufactured by Monolithic Power Systems Inc. and share identical electrical, mechanical, and compliance specifications. Selection between these two part numbers is based on availability and supply chain considerations rather than technical performance differences.

Both parts maintain active product status, ensuring continued manufacturer support and availability. Both are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing and assembly operations.

The 8-SOIC surface-mount package with 0.154" width (3.90mm) is standard for automated pick-and-place assembly processes. Tape & Reel packaging format supports high-volume production workflows.

Frequently Asked Questions (FAQ)

Q: Can MCS1806GS-3-20-Z be used as a direct replacement for MCS1806GS-3-20-P in existing designs?
