Substitute Part Grouping Explanation

The MCS1803GS-05-Z and its substitute part MCS1803GS-05-P are functionally equivalent Hall-effect current sensors. Substitution between these parts is valid based on the following criteria:

Electrical Parameter Equivalence:

• Identical current sensing range (±5A)
• Identical output characteristics (Ratiometric, Voltage at 400mV/A)
• Identical supply voltage requirements (4.5V ~ 5.5V)
• Identical frequency response (100kHz)
• Identical linearity (±0.5%) and accuracy (±2.5%)
• Identical response time (5µs)
• Identical operating temperature range (-40°C ~ 125°C)

Mechanical Parameter Equivalence:

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

Compliance Equivalence:

• Both parts maintain Active product status
• Both parts are RoHS3 compliant
• Both parts have MSL rating of 1 (Unlimited)
• Both parts are REACH Unaffected
• Both parts share identical ECCN and HTSUS classifications

The difference between these part numbers relates to packaging format or supply chain designation rather than functional or electrical characteristics.
