MAX922ESA+ Equivalent & Substitute Parts

Part Overview

The MAX922ESA+ is a dual general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated. This surface-mount 8-SOIC device operates across a wide supply voltage range (2.5V ~ 11V single supply, ±1.25V ~ 5.5V dual supply) and is designed for applications requiring precision voltage comparison with CMOS and TTL output compatibility. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on functional compatibility within the general-purpose comparator category, accounting for differences in packaging, supply voltage ranges, and electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX922ESA+ is determined by the following critical parameters:

• Functional Category: General-purpose dual comparator with CMOS/TTL output capability
• Number of Elements: Dual comparator configuration (2 independent comparators per package)
• Supply Voltage Compatibility: Single supply range 2.5V ~ 11V or dual supply range ±1.25V ~ 5.5V
• Output Type: CMOS and/or TTL output stages
• Package Compatibility: Surface-mount or through-hole packages with identical or functionally equivalent pinout
• Compliance Requirements: RoHS3 compliance and MSL 1 rating

The TS393CD C3G qualifies as a manufacturer-recommended substitute despite packaging differences (8-DIP through-hole versus 8-SOIC surface-mount) because it maintains dual comparator functionality, general-purpose classification, and overlapping supply voltage specifications. The TS393CD C3G supports an extended supply voltage range (2V ~ 36V single supply, ±1V ~ 18V dual supply) that encompasses the MAX922ESA+ operating window, ensuring compatibility in applications within the MAX922ESA+ voltage envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the MAX922ESA+ and TS393CD C3G maintain Active product status with full RoHS3 compliance and MSL 1 ratings, ensuring long-term availability and regulatory compliance for production applications.

The MAX922ESA+ is the primary choice for new surface-mount designs requiring the specified -40°C ~ 85°C operating temperature range and 50mA typical output current capability.

The TS393CD C3G serves as a functional substitute for applications where through-hole mounting is required or where the extended supply voltage range (2V ~ 36V) and lower input offset voltage (2mV @ 5V) provide design advantages. However, the TS393CD C3G operates within a narrower temperature range (0°C ~ 70°C) and delivers lower typical output current (16mA @ 5V), which may limit suitability for high-temperature or high-current-drive applications designed around MAX922ESA+ specifications.

Frequently Asked Questions (FAQ)

Q: Can the TS393CD C3G replace the MAX922ESA+ in all applications?

A: The TS393CD C3G is functionally compatible as a dual general-purpose comparator with overlapping supply voltage specifications. However, design constraints must be evaluated: the TS393CD C3G operates only to 70°C (versus 85°C for MAX922ESA+), delivers 16mA typical output current (versus 50mA), and requires through-hole mounting instead of surface-mount. Applications operating above 70°C or requiring 50mA output drive must use the MAX922ESA+.

Q: What are the key differences between these parts?

A: Primary differences are packaging (8-SOIC surface-mount versus 8-DIP through-hole), operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), output current capability (50mA versus 16mA typical), and input offset voltage (10mV versus 2mV @ 5V). The TS393CD C3G supports a wider supply voltage range but lower quiescent current (1mA versus 5µA).

Q: Are both parts RoHS3 compliant?

A: Yes. Both MAX922ESA+ and TS393CD C3G are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings, suitable for production environments with standard handling and storage protocols.

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

A: For new surface-mount designs, the MAX922ESA+ is the recommended choice. The TS393CD C3G is appropriate only when through-hole mounting is a design requirement or when the extended supply voltage range provides specific system advantages within the 0°C ~ 70°C operating window.
