Substitute Part Grouping Explanation

The MCS1802GS-30-Z and its identified substitute, the MCS1802GS-30-P, are functionally equivalent Hall-effect current sensors from the same manufacturer. Substitution between these parts is valid based on the following critical parameters:

Electrical Equivalence Criteria:

• Identical current sensing range (±30A)
• Identical supply voltage specification (3V ~ 3.6V)
• Identical sensitivity (44mV/A)
• Identical frequency response (100kHz)
• Identical linearity (±0.5%)
• Identical accuracy (±2.5%)
• Identical response time (5µs)
• Identical output configuration (Ratiometric, Voltage)

Mechanical Equivalence Criteria:

• Identical package type (8-SOIC, 0.154", 3.90mm Width)
• Identical mounting type (Surface Mount)
• Identical polarization (Bidirectional)

Compliance Equivalence Criteria:

• Both parts are ROHS3 compliant
• Both parts are REACH unaffected
• Both parts share identical ECCN and HTSUS classifications
• Both parts maintain Active product status

The only difference between these parts is the packaging format: MCS1802GS-30-Z is supplied in Tape & Reel format, while MCS1802GS-30-P is also supplied in Tape & Reel format. Both parts are suitable for direct substitution in applications requiring ±30A bidirectional current sensing with 3.3V operation.
