TLV3701ID Equivalent & Substitute Parts

Part Overview

The TLV3701ID is a general-purpose CMOS comparator manufactured by Texas Instruments, featuring push-pull, rail-to-rail output architecture in an 8-SOIC surface-mount package. This device operates across a wide supply voltage range of 2.7V to 16V (or ±1.35V to ±8V dual supply) and is designed for precision voltage comparison applications requiring low input offset voltage and minimal input bias current.

The TLV3701ID is currently in Last Time Buy status, indicating that Texas Instruments has discontinued or will discontinue production. This necessitates identification of functionally equivalent alternatives to ensure design continuity and supply chain reliability for new production runs or long-term projects.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3701ID is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output type must be CMOS, Push-Pull, Rail-to-Rail or compatible subset
• Supply voltage range must encompass or exceed the application's operating range
• Input offset voltage and input bias current must meet or exceed performance specifications
• Quiescent current must not exceed system power budget constraints
• Operating temperature range must cover the intended application environment

Mechanical Compatibility Requirements:

• Package type and pin configuration must be compatible with existing PCB layouts
• Mounting type must be surface mount
• Physical dimensions must fit within board space constraints

Compliance Requirements:

• RoHS3 compliance required for regulated applications
• MSL rating must be compatible with assembly processes

The substitute parts are grouped into two categories based on package compatibility:

Category 1: 8-SOIC Package (Direct Pin-Compatible Substitutes)

• MAX985ESA+
• MAX987ESA+
• MAX987ESA+T

Category 2: Alternative Packages (Functional Equivalents, Different Pinout)

• TLV3701IDBVR (SOT-23-5 package)
• MAX9027EBT+T (6-WLP package)
• MAX998EUT+T (SOT-6 package)

Engineering Selection Recommendations

For Direct 8-SOIC Package Replacement (No PCB Redesign):

The TLV3701IDBVR (Texas Instruments, SOT-23-5) maintains identical electrical specifications to the TLV3701ID and is in Active product status, making it the primary recommended substitute. However, this requires PCB layout modification due to different pinout and package footprint.

For applications requiring identical 8-SOIC pinout without PCB changes, the MAX985ESA+ and MAX987ESA+/MAX987ESA+T (Analog Devices/Maxim Integrated) are pin-compatible alternatives. These devices feature TTL-compatible output stages and operate within the 2.5V to 5.5V supply range. The MAX987ESA+T variant is available in Cut Tape & Digi-Reel packaging with higher inventory availability (4,568 pcs).

Critical Limitation for MAX985/MAX987 Series: The supply voltage range is restricted to 2.5V–5.5V (or ±1.25V–2.75V dual supply), which is narrower than the TLV3701ID's 2.7V–16V range. These substitutes are suitable only for applications operating within this reduced voltage window.

For Applications Requiring Extended Supply Voltage Range:

The TLV3701IDBVR maintains the full 2.7V–16V supply range and is the only active substitute that preserves this specification. PCB redesign is necessary to accommodate the SOT-23-5 package.

For Space-Constrained Applications:

The MAX998EUT+T (SOT-6 package) offers superior propagation delay performance (28ns) and lower input offset voltage (2mV @ 5V) compared to the TLV3701ID. However, quiescent current is significantly higher (650µA), making it unsuitable for ultra-low-power applications. The MAX9027EBT+T (6-WLP package) provides the smallest footprint but operates only within 1.8V–5.5V supply range and exhibits reduced CMRR/PSRR performance.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. Current inventory levels are adequate across all alternatives, with MAX987ESA+T showing the highest stock availability (4,568 pcs).

Frequently Asked Questions (FAQ)

Q: Can I use MAX985ESA+ or MAX987ESA+ as a direct replacement for TLV3701ID without PCB modification?

A: Yes, these parts are pin-compatible in the 8-SOIC package. However, verify that your application operates within the 2.5V–5.5V supply voltage range. The TLV3701ID supports 2.7V–16V, so applications requiring higher supply voltages cannot use these substitutes.

Q: What is the key difference between MAX987ESA+ and MAX987ESA+T?

A: Both parts are electrically identical. The primary difference is packaging: MAX987ESA+ is supplied in Tube packaging, while MAX987ESA+T is supplied in Cut Tape & Digi-Reel format. Choose based on your assembly process requirements and inventory management preferences.

Q: Why does the TLV3701IDBVR have different electrical performance than the TLV3701ID if they are both Texas Instruments parts?

A: The TLV3701IDBVR is a different product variant with identical electrical specifications but different package (SOT-23-5 vs. 8-SOIC). The base product number TLV3701 indicates the same core die, but packaging and pinout differ. Both maintain the full 2.7V–16V supply range and identical performance parameters.

Q: Is the MAX9027EBT+T suitable for my application if I need extended temperature operation?

A: The MAX9027EBT+T operates only to 85°C maximum, compared to the TLV3701ID's 125°C upper limit. If your application requires operation above 85°C, this part is not suitable. The TLV3701IDBVR is the only active substitute that maintains the -40°C to 125°C operating range.

Q: What are the implications of higher quiescent current in the MAX998EUT+T?

A: The MAX998EUT+T draws 650µA quiescent current compared to 1µA for the TLV3701ID. This 650× increase in standby power consumption makes it unsuitable for battery-powered or ultra-low-power applications. Use this part only in applications where quiescent current is not a design constraint.

Q: Can I use multiple substitute parts interchangeably in the same design?

A: No. Each substitute has different electrical characteristics, package pinouts, and supply voltage ranges. Select a single substitute based on your specific application requirements (supply voltage range, package constraints, temperature range, power budget) and validate the design accordingly. Mixing different substitutes in the same application is not recommended.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (TLV3701IDBVR, MAX985ESA+, MAX987ESA+, MAX987ESA+T, MAX998EUT+T, MAX9027EBT+T) are ROHS3 compliant and suitable for regulated applications requiring lead-free components.
