Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX186AEWP is determined by strict equivalence across the following critical parameters:

• Channel Count: 8 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 133 kHz (fixed requirement)
• Package Type: 20-SOIC form factor (fixed requirement)
• Mounting Type: Surface mount (fixed requirement)
• Operating Temperature Range: -40°C to 85°C (fixed requirement)
• Voltage Supply Configuration: Dual ± supply (fixed requirement)

The MAX186AEWP+ qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status: the MAX186AEWP+ is active and RoHS3 compliant, whereas the original part is obsolete and RoHS non-compliant.
