MAX986EXK-T Equivalent & Substitute Parts

Part Overview

The MAX986EXK-T is a general-purpose CMOS comparator with open-drain, rail-to-rail output and TTL compatibility, manufactured by Analog Devices Inc./Maxim Integrated. This device is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement. The MAX986EXK-T operates across a supply voltage range of 2.5V to 5.5V (single supply) or ±1.25V to 2.75V (dual supply), making it suitable for low-voltage analog signal comparison applications. Active alternatives with identical or compatible electrical characteristics are available to ensure design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX986EXK-T is determined by strict alignment of electrical and mechanical parameters within the general-purpose comparator category. The following key parameters define acceptable substitutes:

Electrical Compatibility Criteria:

• Output type must include open-drain and rail-to-rail capability
• Supply voltage range must encompass or exceed 2.5V ~ 5.5V
• Input offset voltage must not exceed 5mV at rated supply voltage
• Input bias current must remain at or below 1pA
• Quiescent current must not significantly exceed 24µA
• Propagation delay must support the 450ns maximum specification
• Operating temperature range must cover -40°C ~ 85°C minimum

Mechanical Compatibility Criteria:

• Package must be 5-pin surface-mount (5-TSSOP, SC-70-5, SOT-353, or equivalent)
• Mounting type must be surface mount
• Pin configuration must be functionally equivalent

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating of 1 or equivalent

Two substitute parts meet these criteria: MAX986EXK+T (direct Analog Devices equivalent with active product status) and NCS2202SN1T1G (onsemi alternative with extended supply voltage range).

Parameter Comparison

Engineering Selection Recommendations

MAX986EXK+T (Primary Substitute): This part is the direct equivalent of the MAX986EXK-T, manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) with active product status. Electrical specifications are identical across all measured parameters. The primary distinction is packaging format: MAX986EXK+T is supplied in Tape & Reel (TR) configuration versus the obsolete part's standard packaging. This substitute provides seamless design continuity with no circuit modifications required. Inventory availability is significantly higher (3600 pcs vs. 987 pcs), ensuring procurement reliability.

NCS2202SN1T1G (Alternative Substitute): The onsemi NCS2202SN1T1G offers functional equivalence with notable parameter variations. This device extends the supply voltage range to 0.85V ~ 6V, providing greater flexibility for ultra-low-voltage and higher-voltage applications. Quiescent current is reduced to 17µA, offering improved power efficiency. However, propagation delay increases to 1.1µs (2.4× slower than MAX986EXK-T), and hysteresis expands to 20mV (6.7× larger). These differences are acceptable only in applications where response time and threshold precision are non-critical. Operating temperature range extends to 105°C, supporting higher-temperature environments. Package compatibility requires verification: NCS2202SN1T1G uses SOT-23-5 Thin (TSOT-23-5) versus the MAX986EXK-T's SC-70-5, necessitating PCB layout modifications.

Selection Criteria:

• For direct replacement with identical performance: MAX986EXK+T
• For extended supply voltage range or higher operating temperature: NCS2202SN1T1G (with timing and hysteresis trade-offs)
• All substitutes maintain RoHS3 compliance and MSL-1 rating

Frequently Asked Questions (FAQ)

Q: Can MAX986EXK+T be used as a direct replacement for MAX986EXK-T? A: Yes. MAX986EXK+T is electrically and functionally identical to MAX986EXK-T. The primary difference is packaging format (Tape & Reel vs. standard). No circuit modifications are required. Both devices are manufactured by Analog Devices Inc./Maxim Integrated with identical electrical specifications.

Q: What are the key differences between MAX986EXK+T and NCS2202SN1T1G? A: MAX986EXK+T provides identical electrical performance to the original MAX986EXK-T. NCS2202SN1T1G offers extended supply voltage (0.85V ~ 6V vs. 2.5V ~ 5.5V), lower quiescent current (17µA vs. 24µA), and higher operating temperature (105°C vs. 85°C). However, NCS2202SN1T1G has slower propagation delay (1.1µs vs. 450ns) and larger hysteresis (20mV vs. ±3mV). Package types differ: NCS2202SN1T1G uses SOT-23-5 Thin instead of SC-70-5.

Q: Is the NCS2202SN1T1G suitable for high-speed applications? A: No. The NCS2202SN1T1G's propagation delay of 1.1µs is significantly slower than the MAX986EXK-T's 450ns. Applications requiring fast response times should use MAX986EXK+T instead.

Q: Do all substitute parts require PCB layout changes? A: MAX986EXK+T requires no PCB changes; it uses the same SC-70-5 package. NCS2202SN1T1G requires PCB layout modifications due to its SOT-23-5 Thin package, which has different pin spacing and footprint.

Q: Are all substitute parts RoHS3 compliant? A: Yes. MAX986EXK+T and NCS2202SN1T1G are both ROHS3 compliant with MSL-1 rating, matching the environmental compliance of the original MAX986EXK-T.

Q: Which substitute has better inventory availability? A: MAX986EXK+T has 3600 pcs in stock, compared to 987 pcs for the obsolete MAX986EXK-T. NCS2202SN1T1G has the highest availability at 15401 pcs.
