MAX966ESA Equivalent & Substitute Parts

Part Overview

The MAX966ESA is a dual general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated, featuring open-drain, rail-to-rail output configuration in an 8-SOIC surface-mount package. This device operates across a supply voltage range of 1.6V to 5.5V and is designed for precision signal comparison applications requiring low input offset voltage and controlled propagation delay.

The MAX966ESA is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this comparator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX966ESA is determined by strict equivalence across the following critical parameters:

• Functional Type: General-purpose dual comparator
• Output Configuration: Open-drain, rail-to-rail topology
• Supply Voltage Compatibility: 1.6V ~ 5.5V range
• Electrical Performance: Input offset voltage ≤ 7mV @ 5.5V; input bias current ≤ 0.05µA @ 5.5V; quiescent current ≤ 10µA; propagation delay ≤ 20µs
• Package Specification: 8-SOIC surface-mount package with 0.154" (3.90mm) width
• Environmental Compliance: ROHS3 compliant; REACH unaffected; MSL 1

Parts meeting all these criteria are classified as direct substitutes. Variations in product status (active vs. obsolete) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX966ESA+ is a direct substitute for the MAX966ESA. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the MAX966ESA is obsolete, while the MAX966ESA+ is active.

For new designs or applications requiring long-term component availability, the MAX966ESA+ is the appropriate selection. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can MAX966ESA+ replace MAX966ESA in existing designs?

A: Yes. The MAX966ESA+ is electrically and mechanically equivalent to the MAX966ESA. All electrical parameters, package dimensions, and mounting specifications are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between MAX966ESA and MAX966ESA+?

A: The parts are functionally identical. The primary difference is product status: MAX966ESA is obsolete, while MAX966ESA+ is active. The "+" designation in MAX966ESA+ indicates the active product variant from Analog Devices Inc./Maxim Integrated.

Q: Are both parts available in the same package?

A: Yes. Both the MAX966ESA and MAX966ESA+ are supplied in 8-SOIC surface-mount packages with identical dimensions (0.154" width, 3.90mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MAX966ESA and MAX966ESA+ are ROHS3 compliant and REACH unaffected. Moisture sensitivity level (MSL) is 1 for both parts, indicating unlimited shelf life under standard storage conditions.

Q: Which part should be selected for new production?

A: The MAX966ESA+ should be selected for new production and long-term applications. As an active product, it ensures sustained supply chain availability and manufacturer support.
