MAX988ESA+ Equivalent & Substitute Parts

Part Overview

The MAX988ESA+ is a general-purpose comparator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for single or dual supply operation. This active product features open-drain output configuration and is packaged in 8-SOIC surface-mount format. The device is suitable for applications requiring low-power comparison with rail-to-rail input capabilities across a 2.5V to 5.5V single supply or ±1.25V to ±2.75V dual supply range. Equivalent and substitute parts are identified based on matching functional characteristics, electrical performance parameters, and package compatibility within the general-purpose comparator category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX988ESA+ are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Comparator type: General-purpose, open-drain output configuration
• Supply voltage compatibility: Minimum overlap with 2.5V ~ 5.5V range
• Input offset voltage: Maximum 5mV specification
• Input bias current: Maximum 1pA specification
• Output stage: Open-drain topology
• Mounting type: Surface-mount technology
• Compliance: ROHS3 and REACH compliance status

Secondary Compatibility Factors:

• Package form factor and pin count
• Propagation delay performance
• Operating temperature range
• Quiescent current consumption

The NCS2202SQ2T2G from onsemi qualifies as a manufacturer-recommended substitute based on matching open-drain output type, comparable input offset voltage (5mV @ 6V), identical input bias current specification (1pA @ 6V), and full compliance with ROHS3 and REACH requirements. Package differences (SC-88A vs. 8-SOIC) require PCB layout verification but do not affect electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

MAX988ESA+ (Primary Part): Active product status with full ROHS3 and REACH compliance. Recommended for new designs requiring the specified 8-SOIC package footprint and performance envelope. Suitable for applications where the 210ns propagation delay and ±2.5mV hysteresis meet timing and precision requirements.

NCS2202SQ2T2G (Manufacturer-Recommended Substitute): Active product status with full ROHS3 and REACH compliance. Qualifies as a functional substitute where supply voltage range expansion (0.85V ~ 6V) and extended operating temperature range (-40°C ~ 105°C) provide design flexibility. Lower quiescent current (17µA vs. 96µA) offers power consumption advantages. Package change from 8-SOIC to SC-88A (5-TSSOP) requires PCB redesign. Slower propagation delay (1.1µs vs. 210ns) and increased hysteresis (20mV vs. ±2.5mV) must be evaluated against application timing and precision specifications.

Frequently Asked Questions (FAQ)

Q: Can NCS2202SQ2T2G directly replace MAX988ESA+ without PCB modification?

A: No. The NCS2202SQ2T2G uses SC-88A (5-TSSOP/SOT-353) packaging versus the MAX988ESA+ 8-SOIC package. Pin count differs (5 pins vs. 8 pins), requiring PCB layout redesign and schematic verification. Electrical functionality is compatible within specified parameter ranges.

Q: What are the key electrical differences between these parts?

A: Input offset voltage and input bias current specifications are identical (5mV and 1pA respectively). Primary differences include: NCS2202SQ2T2G offers wider supply voltage range (0.85V ~ 6V vs. 2.5V ~ 5.5V), lower quiescent current (17µA vs. 96µA), slower propagation delay (1.1µs vs. 210ns), and higher hysteresis (20mV vs. ±2.5mV). CMRR is 10dB lower on the NCS2202SQ2T2G (70dB vs. 80dB).

Q: Are both parts suitable for low-power applications?

A: The NCS2202SQ2T2G is superior for low-power designs due to 17µA quiescent current versus 96µA on the MAX988ESA+. However, the MAX988ESA+ remains acceptable for applications where the 96µA specification meets power budgets.

Q: What compliance certifications apply to both parts?

A: Both MAX988ESA+ and NCS2202SQ2T2G are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Which part should be selected for timing-critical applications?

A: The MAX988ESA+ is preferred for timing-critical designs due to 210ns maximum propagation delay versus 1.1µs on the NCS2202SQ2T2G. The MAX988ESA+ also provides tighter hysteresis control (±2.5mV vs. 20mV), beneficial for precision threshold detection.

Q: Is the extended temperature range of NCS2202SQ2T2G (-40°C ~ 105°C) a significant advantage?

A: The extended upper temperature limit (105°C vs. 85°C) provides operational margin in high-temperature environments. Selection depends on application thermal requirements. Both parts meet standard industrial temperature specifications.
