MAX992EUA-T Equivalent & Substitute Parts

Part Overview

The MAX992EUA-T is a dual-channel general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated. It features CMOS open-drain, rail-to-rail output architecture with TTL compatibility in an 8-uMAX/uSOP surface-mount package. The device operates across 2.5V to 5.5V single supply or ±1.25V to ±2.75V dual supply configurations.

The MAX992EUA-T is classified as obsolete, with 18,834 units currently in stock. Due to its discontinued status, equivalent and substitute parts are necessary for new designs, production continuity, and long-term component availability. Substitute parts must maintain electrical compatibility across supply voltage ranges, input offset specifications, output characteristics, and thermal operating ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX992EUA-T is determined by the following critical parameters:

Primary Compatibility Criteria:

Dual-channel comparator architecture (2 elements)
Open-drain output configuration
Supply voltage range overlap with 2.5V ~ 5.5V
Input offset specification ≤ 5mV
Input bias current ≤ 1pA
Operating temperature range including -40°C to 85°C
8-pin surface-mount package (8-TSSOP/8-MSOP)
ROHS3 compliance and MSL 1 rating

Substitute parts are grouped into two categories:

Category 1: Direct Parametric Equivalents Parts with identical or superior electrical specifications across all critical parameters, including supply voltage range, input offset, bias current, and propagation delay characteristics.

Category 2: Functional Equivalents with Extended Capabilities Parts that meet core substitution criteria but may feature extended supply voltage ranges, improved CMRR/PSRR performance, or different output type configurations (push-pull in addition to open-drain). These parts are suitable for applications where the extended specifications do not conflict with existing circuit design constraints.

Engineering Selection Recommendations

Recommended Primary Substitute: MAX992EUA+T

The MAX992EUA+T is the direct parametric equivalent of the MAX992EUA-T, with identical electrical specifications and performance characteristics. The primary distinction is product status: MAX992EUA+T is active and available in Tape & Reel packaging, ensuring long-term supply continuity. This part is the preferred choice for design migration from the obsolete MAX992EUA-T.

Secondary Substitutes for Extended Supply Range Applications:

TLV3402IDGKR (Texas Instruments, Active) is suitable for applications requiring extended operating temperature range (-40°C to 125°C) and higher supply voltage tolerance (2.7V ~ 16V). This part maintains CMOS open-drain output configuration and ROHS3 compliance. The extended temperature range accommodates industrial and automotive environments beyond the original MAX992EUA-T specification.

Functional Alternatives with Trade-offs:

HA1631D03MMEL-E (Renesas Electronics, Active) provides dual-channel open-drain and push-pull output options with lower quiescent current (20µA vs. 96µA). Extended supply voltage range (1.8V ~ 5.5V) supports low-power applications. Propagation delay is not specified; circuit validation is required for timing-critical applications.

LMC6772AIMM/NOPB (Texas Instruments, Active) offers extended supply voltage range (2.7V ~ 15V) and superior input bias current performance (0.04pA). Propagation delay specification (10µs) is significantly longer than MAX992EUA-T (210ns), limiting suitability for high-speed switching applications.

Parts Approaching End-of-Life:

TLV3402CDGK, TLV3402CDGKR, TLV3402IDGK, TLV2302IDGK, and TLV2302IDGKR are classified as Last Time Buy. While electrically compatible, these parts face supply discontinuation and should not be selected for new long-term production designs.

Frequently Asked Questions (FAQ)

Q: Can MAX992EUA+T be used as a direct replacement for MAX992EUA-T?

A: Yes. MAX992EUA+T is electrically and functionally identical to MAX992EUA-T. The difference is packaging format (Tape & Reel vs. standard tube) and product status (Active vs. Obsolete). Both parts meet identical electrical specifications and are pin-compatible in 8-TSSOP/MSOP packages.

Q: What is the key difference between MAX992EUA-T and TLV3402IDGKR?

A: TLV3402IDGKR extends the operating temperature range to -40°C ~ 125°C (vs. -40°C ~ 85°C) and supports higher supply voltages (2.7V ~ 16V vs. 2.5V ~ 5.5V). However, propagation delay is significantly longer (300µs vs. 210ns), making it unsuitable for applications requiring fast switching response. Input bias current is also higher (250pA vs. 1pA).

Q: Is LMC6772AIMM/NOPB suitable for high-speed comparator applications?

A: No. LMC6772AIMM/NOPB has a maximum propagation delay of 10µs, which is approximately 48 times slower than MAX992EUA-T (210ns). This part is designed for low-speed, low-power applications and is not appropriate for timing-critical circuits.

Q: Why should I avoid TLV2302IDGK and TLV2302IDGKR?

A: Both parts are classified as Last Time Buy, indicating manufacturer discontinuation. Complete electrical specifications are not provided in the datasheet. These parts should not be selected for new designs requiring long-term component availability.

Q: Can HA1631D03MMEL-E replace MAX992EUA-T in all applications?

A: HA1631D03MMEL-E is functionally compatible for most general-purpose comparator applications. However, propagation delay is not specified, and the part offers both open-drain and push-pull output options. Circuit validation is required to confirm timing performance and output drive characteristics match application requirements.

Q: What packaging formats are available for substitute parts?

A: MAX992EUA+T is available in Tape & Reel (TR) format. TLV3402IDGKR is available in Cut Tape (CT) & Digi-Reel format. TLV3402CDGK, TLV3402IDGK, and TLV2302IDGK are supplied in Tube packaging. All parts use identical 8-TSSOP/8-MSOP surface-mount package geometry (0.118", 3.00mm width).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, matching the environmental and regulatory requirements of MAX992EUA-T.
