MAX967ESA+ Equivalent & Substitute Parts

Part Overview

The MAX967ESA+ is an active linear comparator integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device combines dual comparator functionality with integrated voltage reference in an 8-SOIC surface mount package. The MAX967ESA+ is classified as an Active product with full RoHS3 compliance and REACH unaffected status, making it suitable for current production applications requiring precision voltage comparison with rail-to-rail output capability.

Substitute parts are identified when designs require alternative sourcing due to inventory constraints, supply chain disruptions, or when parametric equivalents meet the electrical and mechanical requirements of the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX967ESA+ is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Supply voltage range must encompass or match 1.6V ~ 5.5V
• Output type must be Open-Drain, Rail-to-Rail
• Voltage input offset maximum must not exceed 7mV @ 5.5V
• Propagation delay maximum must not exceed 20µs
• Hysteresis must be ±1mV
• Operating temperature range must cover -40°C ~ 85°C

Mechanical Compatibility Requirements:

• Package must be 8-SOIC (0.154", 3.90mm Width)
• Mounting type must be Surface Mount

Compliance Requirements:

• Product status must be Active
• RoHS3 compliance required
• REACH unaffected status required

The MAX967ESA+ is a direct equivalent to itself. The MAX965ESA+ qualifies as a parametric equivalent despite having a single comparator element instead of dual elements, as all electrical performance parameters remain within specification and the package, mounting type, and compliance certifications are identical.

Parameter Comparison

Engineering Selection Recommendations

MAX967ESA+ (Direct Equivalent): This part number is identical to the main part specification. Selection is appropriate when inventory availability matches project requirements and no alternative sourcing is necessary.

MAX965ESA+ (Parametric Equivalent): This part qualifies as a substitute when the application circuit requires only a single comparator channel. The MAX965ESA+ maintains all critical electrical performance parameters including input offset voltage, propagation delay, hysteresis, and supply voltage range. The lower quiescent current (12µA versus 16µA) represents an operational advantage in power-constrained applications. Both parts share identical package geometry, mounting type, and compliance certifications. Selection of the MAX965ESA+ is valid only when circuit design accommodates single-element comparator functionality.

Both substitute options maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring compatibility with current manufacturing and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can MAX965ESA+ replace MAX967ESA+ in all applications?

A: The MAX965ESA+ is electrically compatible with MAX967ESA+ specifications for all common parameters including supply voltage, input offset, propagation delay, and hysteresis. However, the MAX965ESA+ contains a single comparator element versus the dual elements in MAX967ESA+. Substitution is valid only when the circuit design requires single-channel comparator functionality. Designs utilizing both comparator channels in the MAX967ESA+ cannot use the MAX965ESA+ without circuit modification.

Q: Are package dimensions identical between MAX967ESA+ and MAX965ESA+?

A: Yes. Both parts use the 8-SOIC package with 0.154" width and 3.90mm width specification. PCB footprints and land patterns are identical, enabling direct physical substitution without layout changes.

Q: Do both substitute parts meet current compliance requirements?

A: Yes. Both MAX967ESA+ and MAX965ESA+ are Active products with ROHS3 compliance and REACH unaffected status. Both are suitable for production applications subject to current environmental and regulatory requirements.

Q: What is the difference in quiescent current between these parts?

A: The MAX967ESA+ has a maximum quiescent current of 16µA, while the MAX965ESA+ has a maximum of 12µA. The MAX965ESA+ offers lower standby power consumption, which may be advantageous in battery-powered or low-power applications.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Physical substitution is possible due to identical package and mounting specifications. However, electrical substitution depends on circuit requirements. If the design uses both comparator channels, only MAX967ESA+ is suitable. If the design uses a single comparator channel, MAX965ESA+ is electrically compatible.
