Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9028EBT-T is determined by strict equivalence across the following critical parameters:

• Functional Type: General-purpose comparator with single element configuration
• Output Architecture: Open-drain, rail-to-rail output topology
• Supply Voltage Compatibility: 1.8V ~ 5.5V single/dual supply range
• Electrical Performance: Input offset voltage, input bias current, output current, quiescent current, CMRR/PSRR, propagation delay, and hysteresis specifications
• Thermal Operating Range: -40°C ~ 85°C
• Package Compatibility: 6-WLP (6-WFBGA, WLBGA) surface-mount package
• Compliance Standards: ROHS3 compliance and MSL rating

The MAX9028EBT+T meets all these criteria as a parametric equivalent and serves as the direct substitute for the obsolete MAX9028EBT-T variant.

Parameter Comparison

Engineering Selection Recommendations

The MAX9028EBT+T is the direct active equivalent for the obsolete MAX9028EBT-T. Selection of the MAX9028EBT+T is based on:

• Product Status Alignment: The MAX9028EBT+T maintains active production status, ensuring continued availability and supply chain reliability compared to the obsolete MAX9028EBT-T.
• Electrical Equivalence: All electrical parameters, including supply voltage range, input offset voltage, bias current, output current, frequency response characteristics (CMRR/PSRR), propagation delay, and hysteresis, are identical between the two variants.
• Package and Mounting Compatibility: Both variants utilize the identical 6-WLP surface-mount package, enabling direct PCB layout compatibility without redesign.
• Compliance Certification: Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying regulatory and environmental requirements.
• Packaging Format Difference: The MAX9028EBT+T is supplied in Cut Tape (CT) and Digi-Reel® packaging, providing standard production-ready formats compared to the obsolete variant.

Frequently Asked Questions (FAQ)

Q: Can the MAX9028EBT+T be used as a direct replacement for the MAX9028EBT-T in existing designs?

A: Yes. The MAX9028EBT+T is electrically and mechanically equivalent to the MAX9028EBT-T. All electrical parameters, package dimensions, and pinout are identical. No circuit modifications or PCB redesign are required.

Q: What is the primary difference between MAX9028EBT-T and MAX9028EBT+T?
