TLV3701CDBVT Equivalent & Substitute Parts

Part Overview

The TLV3701CDBVT is a general-purpose CMOS comparator with push-pull, rail-to-rail output in SOT-23-5 surface mount packaging. This device operates across a supply voltage range of 2.5V to 16V (single supply) or ±1.25V to ±8V (dual supply), with a maximum input offset voltage of 5mV at 15V and quiescent current of 1µA maximum. The TLV3701CDBVT is currently classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV3701CDBVT are classified based on the following substitution criteria:

Primary Substitution Parameters:

• Output Type: CMOS, Push-Pull, Rail-to-Rail
• Package / Case: SOT-23-5 or compatible surface mount packages
• Voltage - Supply Range: Minimum 2.5V single supply capability
• Voltage - Input Offset (Max): 5mV or lower
• Current - Input Bias (Max): 250pA or lower
• Current - Quiescent (Max): 1µA or lower
• Operating Temperature: Minimum 0°C lower bound
• RoHS Status: ROHS3 Compliant

MFR Recommended Substitutes are parts from the original manufacturer (Texas Instruments) with active or last-time-buy status that maintain identical or superior electrical characteristics within the same package family.

Parametric Equivalents are parts from alternative manufacturers that meet the core electrical and mechanical requirements, though they may have different supply voltage ranges or operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

TLV3701IDBVR (MFR Recommended - Active Status)

The TLV3701IDBVR is the primary recommended substitute. It is manufactured by Texas Instruments with active product status and maintains identical electrical specifications to the TLV3701CDBVT. The supply voltage range is marginally extended (2.7V minimum versus 2.5V), and the operating temperature range is significantly expanded (-40°C to 125°C versus 0°C to 70°C). This part is available in the same SOT-23-5 package and is ROHS3 compliant with MSL 1 rating. Inventory availability is substantial at 36,900 pieces.

TLV3701CDBVR (Parametric Equivalent - Last Time Buy)

The TLV3701CDBVR provides identical electrical and thermal specifications to the TLV3701CDBVT, including the same 2.5V to 16V supply range and 0°C to 70°C operating temperature. This part carries last-time-buy status, indicating limited future availability. It is suitable for applications requiring exact parameter matching but should be considered a transitional solution with TLV3701IDBVR as the long-term alternative.

MAX9100EUK+T (Parametric Equivalent - Active Status)

The MAX9100EUK+T from Analog Devices Inc./Maxim Integrated is an active product in SOT-23-5 packaging. This part operates across 1V to 5.5V supply range, which is narrower than the TLV3701CDBVT. Input offset voltage is 10mV at 5.5V (higher than the 5mV specification), and quiescent current is 13µA (higher than 1µA). This part is suitable only for applications operating within the 1V to 5.5V range where the higher quiescent current and input offset are acceptable.

MAX9119EXK+T (Parametric Equivalent - Active Status)

The MAX9119EXK+T is an active Analog Devices Inc./Maxim Integrated product in SC-70-5 package (different from SOT-23-5). It operates across 1.6V to 5.5V supply range with 5mV input offset at 5V and 1.2µA quiescent current. This part features higher typical output current (50mA versus 10mA) and extended operating temperature (-40°C to 85°C). Package substitution requires PCB layout modification.

MAX998ESA+T (Parametric Equivalent - Active Status)

The MAX998ESA+T is an active Analog Devices Inc./Maxim Integrated product in 8-SOIC package. It operates across 2.7V to 5.5V supply range with superior input offset (2mV at 5V) and CMRR/PSRR specifications (95dB/100dB). However, quiescent current is significantly higher at 650µA, and the package is substantially different (8-SOIC versus SOT-23-5), requiring complete PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can TLV3701IDBVR directly replace TLV3701CDBVT without PCB modification?

A: Yes. The TLV3701IDBVR is pin-compatible in the same SOT-23-5 package. The extended operating temperature range (-40°C to 125°C) and marginally higher minimum supply voltage (2.7V versus 2.5V) do not prevent direct substitution in most applications. Verify that your application does not require operation below 2.7V supply voltage.

Q: What is the difference between TLV3701CDBVR and TLV3701IDBVT?

A: The TLV3701CDBVR and TLV3701IDBVT are both Texas Instruments parts with identical electrical specifications. The primary difference is product status: TLV3701CDBVR is last-time-buy (limited availability), while TLV3701IDBVT is active (ongoing production). For new designs, TLV3701IDBVR is preferred.

Q: Why do MAX9100EUK+T and MAX9119EXK+T have different supply voltage ranges?

A: These are different product lines from Analog Devices Inc./Maxim Integrated optimized for different application spaces. MAX9100EUK+T targets low-voltage applications (1V to 5.5V), while MAX9119EXK+T is designed for slightly higher minimum voltage (1.6V to 5.5V) with enhanced output current capability. Neither fully covers the TLV3701CDBVT's extended 2.5V to 16V range.

Q: Can I use MAX998ESA+T as a substitute if I redesign the PCB?

A: MAX998ESA+T is functionally compatible but requires complete PCB redesign due to package change from SOT-23-5 to 8-SOIC. Additionally, quiescent current is 650µA versus 1µA, which significantly impacts power consumption in battery-powered applications. Evaluate power budget impact before proceeding.

Q: What are the key parameters that determine substitutability?

A: The critical parameters are: (1) Output Type (CMOS, Push-Pull, Rail-to-Rail), (2) Supply voltage range compatibility with your application, (3) Input offset voltage and input bias current specifications, (4) Quiescent current for power-sensitive designs, (5) Package compatibility or redesign feasibility, and (6) Operating temperature range coverage. All substitute parts maintain ROHS3 compliance and MSL 1 rating.

Q: Is TLV3701CDBVR still available for new production orders?

A: TLV3701CDBVR carries last-time-buy status, indicating limited future availability. Current inventory is 3,913 pieces. For new production programs, TLV3701IDBVR (36,900 pieces in stock) is the recommended choice to ensure long-term supply continuity.
