Substitute Part Grouping Explanation

Substitution eligibility for the MCS1806GS-5-20-P is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part MCS1806GS-5-20-Z shares identical specifications in the following key areas:

Electrical Equivalence Criteria:

• Current sensing range: ±20A
• Sensor topology: Hall Effect, Differential
• Output configuration: Ratiometric, Voltage
• Sensitivity: 100mV/A
• Frequency response: 100kHz
• Linearity tolerance: ±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

Mechanical & Compliance Equivalence Criteria:

• Package: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH unaffected status
• ECCN: EAR99
• HTSUS: 8542.39.0001

The only difference between these parts is the packaging format designation (P for Tape & Reel standard packaging versus Z for alternative tape & reel configuration), which does not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations
