Substitute Part Grouping Explanation

Substitution eligibility for the MCS1802GS-20-P is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part MCS1802GS-20-Z qualifies as a direct parametric equivalent based on the following criteria:

Critical Substitution Parameters:

• Identical current sensing range (±20A)
• Identical sensor type (Hall Effect)
• Identical output configuration (Ratiometric, Voltage)
• Identical sensitivity specification (66mV/A)
• Identical supply voltage range (3V ~ 3.6V)
• Identical frequency response (100kHz)
• Identical linearity tolerance (±0.5%)
• Identical accuracy specification (±2.5%)
• Identical response time (5µs)
• Identical operating temperature range (-40°C ~ 125°C)
• Identical package and pinout (8-SOIC, 0.154", 3.90mm Width)
• Identical mounting type (Surface Mount)
• Identical polarization (Bidirectional)
• Identical compliance certifications (ROHS3, REACH Unaffected)

Both parts are manufactured by Monolithic Power Systems Inc. and maintain Active product status. The substitution relationship is bidirectional, indicating full interchangeability at the component level.
