MAX6369KA-T Equivalent & Substitute Parts

Part Overview

The MAX6369KA-T is a single-channel supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications. This component functions as a watchdog circuit with open drain or open collector output, operating across the industrial temperature range of -40°C to 125°C. The MAX6369KA-T is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain functional equivalence while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX6369KA-T is determined by strict equivalence across the following critical parameters:

• Watchdog Circuit Type: All substitute parts function as single-channel watchdog supervisors
• Voltage Monitoring: Single voltage channel with adjustable/selectable threshold
• Output Configuration: Open drain or open collector output with active low reset
• Reset Timeout: Adjustable/selectable timeout functionality
• Operating Temperature Range: -40°C to 125°C industrial range
• Package: SOT-23-8 surface mount package
• Electrical Characteristics: Identical functional specifications across all listed substitutes

The substitute parts are grouped into two categories: direct manufacturer equivalents (MAX6369KA+T) and parametric equivalents from the same MAX63xx supervisor family (MAX6369KA/V+T, MAX6371KA+T, MAX6373KA+T). All substitutes maintain identical electrical and mechanical compatibility with the original MAX6369KA-T design.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MAX6369KA+T

The MAX6369KA+T is the direct manufacturer equivalent of the MAX6369KA-T, offering identical electrical and mechanical specifications. This part is currently in active production status with significantly higher inventory availability (47,700 units). The MAX6369KA+T achieves ROHS3 compliance, addressing environmental regulatory requirements that the obsolete MAX6369KA-T does not meet. For standard industrial applications, this is the preferred substitute.

Automotive-Grade Alternative: MAX6369KA/V+T

The MAX6369KA/V+T provides the same functional equivalence as the MAX6369KA-T with additional automotive qualification (AEC-Q100). This variant is suitable for applications requiring automotive-grade components and compliance certifications. Inventory availability is lower (3,500 units) compared to the standard MAX6369KA+T.

Parametric Equivalents: MAX6371KA+T and MAX6373KA+T

The MAX6371KA+T and MAX6373KA+T are parametric equivalents from the MAX63xx supervisor family, maintaining all critical functional parameters including single-channel voltage monitoring, adjustable threshold, open drain output, and active low reset. These parts are in active production with strong inventory levels (16,565 and 22,693 units respectively) and ROHS3 compliance. Selection between these variants depends on specific voltage threshold requirements defined in the application datasheet.

Frequently Asked Questions (FAQ)

Q: Can MAX6369KA+T be used as a direct replacement for MAX6369KA-T?

A: Yes. The MAX6369KA+T is the direct manufacturer equivalent with identical electrical and mechanical specifications. Both parts function as single-channel watchdog supervisors in SOT-23-8 packages with adjustable voltage thresholds, open drain output, and active low reset. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What is the difference between MAX6369KA+T and MAX6371KA+T?

A: Both parts are functionally equivalent watchdog supervisors with identical electrical characteristics, operating temperature range, and SOT-23-8 packaging. The difference lies in the base product number (MAX6369 vs. MAX6371), which may indicate different voltage threshold configurations. Consult the manufacturer datasheet to confirm threshold compatibility with your application.

Q: Is MAX6369KA/V+T suitable for automotive applications?

A: Yes. The MAX6369KA/V+T carries AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. It maintains all functional equivalence to the MAX6369KA-T while meeting automotive industry standards.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed (MAX6369KA+T, MAX6369KA/V+T, MAX6371KA+T, MAX6373KA+T) are ROHS3 compliant. The original MAX6369KA-T is RoHS non-compliant. If RoHS compliance is required for your application, any of the substitute parts will satisfy this requirement.

Q: Can these parts be used interchangeably in the same PCB layout?

A: Yes. All substitute parts use the SOT-23-8 surface mount package with identical pinout and electrical characteristics. No PCB layout modifications are required for substitution.

Q: What inventory considerations should guide part selection?

A: The MAX6369KA+T offers the highest inventory availability (47,700 units), followed by MAX6373KA+T (22,693 units) and MAX6371KA+T (16,565 units). The automotive-qualified MAX6369KA/V+T has lower availability (3,500 units). For high-volume production, the MAX6369KA+T is the most practical choice.
