Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9052AEUA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Dual-channel comparator with integrated voltage reference
• Output Configuration: CMOS push-pull, rail-to-rail, TTL-compatible
• Supply Voltage Compatibility: 2.7V ~ 5.5V range
• Package Footprint: 8-pin TSSOP/MSOP with identical pinout
• Electrical Performance: Matching propagation delay (450ns max), hysteresis (±3mV), and frequency response characteristics
• Environmental Compliance: ROHS3 compliance and MSL rating
• Thermal Range: -40°C ~ 85°C operating specification

The MAX9052BEUA+T meets all substitution criteria as an active-status equivalent with identical functional specifications and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX9052BEUA+T is the direct substitute for the obsolete MAX9052AEUA-T. Both parts share identical electrical specifications, package footprint, and thermal operating range. The substitute offers improved input offset voltage performance (1mV versus 5mV) while maintaining all other critical parameters. Quiescent current is slightly elevated (130µA versus 85µA) but remains within acceptable limits for most applications.

Selection of the MAX9052BEUA+T is supported by its active product status, ensuring long-term availability and manufacturing continuity. Both parts maintain ROHS3 compliance and MSL 1 rating, confirming environmental and moisture handling compatibility. The identical 8-pin TSSOP/MSOP package enables direct PCB footprint compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the MAX9052BEUA+T be used as a direct replacement for the MAX9052AEUA-T?

A: Yes. Both parts are functionally equivalent with identical supply voltage range, output configuration, propagation delay, hysteresis, and package footprint. The substitute is pin-compatible and requires no circuit modification.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active) and two electrical parameters. The MAX9052BEUA+T features improved input offset voltage (1mV versus 5mV) and slightly higher quiescent current (130µA versus 85µA). These differences do not affect functional compatibility in standard comparator applications.

Q: Are there packaging differences between the main part and substitute?

A: No. Both parts use identical 8-pin TSSOP/MSOP packaging with 0.118" width and 3.00mm height. PCB footprints are identical, and no layout changes are required.

Q: What is the significance of the product status change from obsolete to active?

A: The active status of the MAX9052BEUA+T ensures continued manufacturing, availability, and technical support from Analog Devices Inc./Maxim Integrated. This eliminates supply chain risk associated with obsolete components.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both the MAX9052AEUA-T and MAX9052BEUA+T are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. Environmental handling and storage requirements are identical.

Q: Is the improved input offset voltage of the substitute beneficial?

A: The lower input offset voltage (1mV) of the MAX9052BEUA+T provides improved accuracy in precision comparator applications. This represents a performance enhancement with no negative impact on existing designs.
