MAX992ESA Equivalent & Substitute Parts

Part Overview

The MAX992ESA is a dual general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated, featuring CMOS open-drain output with rail-to-rail input capability and TTL compatibility. The device is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The MAX992ESA operates across a supply voltage range of 2.5V to 5.5V (single supply) or ±1.25V to ±2.75V (dual supply), with an 8-SOIC surface-mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX992ESA are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution logic is determined by the following parameters:

Critical Matching Parameters:

• Package type: 8-SOIC surface-mount form factor
• Functional classification: Dual general-purpose comparator
• Output configuration: Open-drain capability with TTL compatibility
• Supply voltage range compatibility
• Input offset voltage performance
• Operating temperature range

Substitute Categories:

Direct Manufacturer Equivalent (MAX992ESA+): Identical electrical specifications and package. Differs only in product status (Active vs. Obsolete) and packaging format (Tube). Electrical parameters are 100% aligned with the original part.

Cross-Manufacturer Alternatives (ALD2303SAL, ALD2303ASAL): Advanced Linear Devices Inc. comparators with compatible 8-SOIC packaging and open-drain output. These parts operate within different supply voltage ranges (3V ~ 10V single supply vs. 2.5V ~ 5.5V for MAX992ESA) and exhibit different input offset voltage and quiescent current specifications. Substitution is valid only when the application's supply voltage and performance requirements fall within the ALD2303 series operating parameters.

Parameter Comparison

Engineering Selection Recommendations

MAX992ESA+ (Direct Equivalent): This part is the primary substitute for the obsolete MAX992ESA. It maintains identical electrical specifications and operating parameters while offering active product status and availability. The only differences are packaging format (Tube) and manufacturer inventory status. This part is suitable for direct replacement in all applications where the original MAX992ESA was specified.

ALD2303SAL and ALD2303ASAL (Cross-Manufacturer Alternatives): These Advanced Linear Devices comparators are functionally compatible alternatives when the application's operating conditions align with their specified parameters. Key considerations include:

• Supply voltage range: ALD2303 series supports 3V ~ 10V (single supply), which encompasses the MAX992ESA's 2.5V ~ 5.5V range but extends to higher voltages
• Operating temperature: ALD2303 series operates 0°C ~ 70°C, which is narrower than MAX992ESA's -40°C ~ 85°C range
• Input offset voltage: ALD2303ASAL offers superior performance (1mV vs. 5mV)
• Quiescent current: ALD2303ASAL provides lower power consumption (40µA vs. 96µA)

Selection of ALD2303 variants requires verification that the application does not require operation below 0°C or above 70°C, and that the extended upper supply voltage limit does not introduce design constraints.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and 8-SOIC package compatibility, ensuring regulatory and physical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can MAX992ESA+ be used as a direct replacement for MAX992ESA?

A: Yes. MAX992ESA+ is electrically and functionally identical to MAX992ESA. The differences are product status (Active vs. Obsolete) and packaging format (Tube). All electrical specifications, operating parameters, and package dimensions are equivalent.

Q: What are the key differences between MAX992ESA and ALD2303 series comparators?

A: The primary differences are supply voltage range (MAX992ESA: 2.5V ~ 5.5V vs. ALD2303: 3V ~ 10V), operating temperature range (MAX992ESA: -40°C ~ 85°C vs. ALD2303: 0°C ~ 70°C), and input offset voltage performance. ALD2303ASAL offers superior input offset voltage (1mV vs. 5mV) and lower quiescent current (40µA vs. 96µA).

Q: Can ALD2303SAL or ALD2303ASAL be used in applications requiring -40°C operation?

A: No. ALD2303 series comparators are specified for 0°C ~ 70°C operating temperature. Applications requiring operation below 0°C must use MAX992ESA or MAX992ESA+.

Q: Are all substitute parts in the same package?

A: Yes. MAX992ESA, MAX992ESA+, ALD2303SAL, and ALD2303ASAL are all housed in 8-SOIC (0.154", 3.90mm Width) surface-mount packages. PCB layout and footprints are mechanically compatible.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original MAX992ESA specifications.

Q: Which substitute part should be selected for new designs?

A: MAX992ESA+ is the recommended choice for new designs, as it maintains identical electrical specifications to the original part while offering active product status and current availability. ALD2303 series parts are suitable alternatives only when the application's supply voltage and operating temperature requirements are compatible with their specified ranges.
