TLV3401ID Equivalent & Substitute Parts

Part Overview

The TLV3401ID is a general-purpose CMOS comparator with open-drain output in 8-SOIC surface mount packaging, manufactured by Texas Instruments. This device operates across a wide supply voltage range of 2.7V to 16V (single supply) or ±1.35V to ±8V (dual supply), making it suitable for diverse analog signal comparison applications. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain component availability for new production runs and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3401ID is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output type must be CMOS, Open-Drain to maintain circuit interface compatibility
• Supply voltage range must encompass or match the 2.7V ~ 16V (single) or ±1.35V ~ ±8V (dual) specification
• Input offset voltage, input bias current, quiescent current, and propagation delay must be within acceptable operating margins for the target application
• CMRR and PSRR performance must support the required signal rejection characteristics

Physical Compatibility Requirements:

• Package type and pin configuration must be compatible with existing PCB layouts
• Surface mount mounting type must be maintained
• Thermal and mechanical specifications must support the operating environment

Regulatory & Compliance Requirements:

• RoHS3 compliance status must be maintained
• MSL rating must be compatible with assembly processes

Substitute parts are grouped based on whether they maintain these core parameters while potentially offering different packaging options or improved product status (Active vs. Last Time Buy).

Engineering Selection Recommendations

TLV3401IDBVR (Texas Instruments)

The TLV3401IDBVR is the direct functional equivalent of the TLV3401ID, maintaining identical electrical specifications including supply voltage range (2.7V ~ 16V / ±1.35V ~ ±8V), input offset voltage (3.6mV @ 15V), quiescent current (950nA), and propagation delay (300µs). The primary difference is packaging: TLV3401IDBVR is supplied in SOT-23-5 (SC-74A) form factor versus the 8-SOIC of the main part. This substitute is in Active product status, ensuring long-term availability. Selection of this part requires PCB redesign to accommodate the smaller SOT-23-5 package footprint. ROHS3 compliance and MSL rating are maintained.

MAX988ESA+ and MAX988ESA+T (Analog Devices Inc./Maxim Integrated)

The MAX988ESA+ and MAX988ESA+T are functionally equivalent in electrical performance but operate within a narrower supply voltage range (2.5V ~ 5.5V / ±1.25V ~ ±2.75V) compared to the TLV3401ID. Both maintain 8-SOIC packaging, eliminating the need for PCB redesign. These parts offer superior propagation delay performance (210ns versus 300µs) and lower input bias current (1pA versus 250pA). However, quiescent current is significantly higher (96µA versus 950nA), and CMRR/PSRR performance is reduced (80dB versus 88dB/105dB). Operating temperature range is limited to -40°C ~ 85°C. Both variants are in Active product status with ROHS3 compliance. Selection is appropriate only for applications operating within the 2.5V ~ 5.5V supply range where the higher quiescent current and reduced noise rejection are acceptable trade-offs.

Frequently Asked Questions (FAQ)

Q: Can TLV3401IDBVR be used as a direct replacement for TLV3401ID without circuit modification?

A: TLV3401IDBVR maintains identical electrical specifications and can function as a direct electrical replacement. However, it uses SOT-23-5 packaging instead of 8-SOIC, requiring PCB layout changes. Pin configuration differences must be verified against the respective datasheets before implementation.

Q: What are the key limitations when substituting MAX988ESA+ for TLV3401ID?

A: The MAX988ESA+ operates only within 2.5V ~ 5.5V supply range, making it unsuitable for applications requiring the full 2.7V ~ 16V range of the TLV3401ID. Additionally, quiescent current is 100 times higher (96µA versus 950nA), which impacts power consumption in battery-powered designs. CMRR and PSRR are reduced by 8dB and 25dB respectively.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLV3401IDBVR, MAX988ESA+, and MAX988ESA+T are all ROHS3 compliant with MSL rating of 1 (Unlimited), maintaining regulatory compatibility with the original TLV3401ID.

Q: Which substitute offers the best long-term availability?

A: TLV3401IDBVR and MAX988ESA+ variants are both in Active product status, ensuring continued manufacturing and distribution. The original TLV3401ID is in Last Time Buy status, indicating production discontinuation.

Q: Can MAX988ESA+ be used in high-temperature applications?

A: No. MAX988ESA+ operates only to 85°C maximum, whereas TLV3401ID supports -40°C ~ 125°C. Applications requiring operation above 85°C must use TLV3401IDBVR or remain with the original TLV3401ID.

Q: What is the primary advantage of TLV3401IDBVR over MAX988ESA+?

A: TLV3401IDBVR maintains the full supply voltage range (2.7V ~ 16V) and extended temperature range (-40°C ~ 125°C) of the original TLV3401ID, with significantly lower quiescent current (950nA versus 96µA) and superior noise rejection (88dB CMRR, 105dB PSRR versus 80dB both). The trade-off is package size change from 8-SOIC to SOT-23-5.
