Parameter Comparison

Engineering Selection Recommendations

The MAX4019EEE+ is the direct substitute for the obsolete MAX4019EEE. Both components share identical electrical specifications and physical packaging, ensuring pin-for-pin and functional compatibility in existing circuit designs.

Primary Substitution Basis:

The MAX4019EEE+ is recommended as the replacement component based on the following factors:

1. Product Status: The MAX4019EEE is classified as obsolete, while the MAX4019EEE+ maintains active product status with ongoing manufacturer support and availability.

2. Regulatory Compliance: The MAX4019EEE+ achieves ROHS3 compliance, whereas the original MAX4019EEE is non-compliant. This distinction is significant for applications subject to RoHS directives and environmental regulations.

3. Electrical Equivalence: All electrical parameters, including slew rate, bandwidth, supply current, output current, and temperature range, are identical between the two parts.

4. Physical Compatibility: Both components utilize the 16-QSOP surface mount package with identical pin configuration, footprint, and MSL rating.

5. Procurement Advantage: The MAX4019EEE+ maintains current inventory availability (2000 pcs in stock) compared to the obsolete status of the original part.

No additional testing or design modifications are required when transitioning from MAX4019EEE to MAX4019EEE+. The substitution is direct and complete.
