TLV3701IDR Equivalent & Substitute Parts

Part Overview

The TLV3701IDR 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 (single/dual ±1.35V to ±8V) and is designed for precision voltage comparison applications requiring low input offset voltage and minimal input bias current.

The TLV3701IDR is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for new designs or production transitions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3701IDR is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output type must be CMOS, Push-Pull, Rail-to-Rail
• Supply voltage range must encompass or overlap with 2.7V ~ 16V (single) or ±1.35V ~ 8V (dual)
• Input offset voltage must not exceed 5mV
• Input bias current must not exceed 250pA
• Operating temperature range must support -40°C ~ 125°C minimum

Mechanical Compatibility Requirements:

• Package must be surface-mount compatible
• Pin count and footprint must support direct or adapter-based substitution

Compliance Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred

Substitute parts are grouped into two categories based on package compatibility: direct 8-SOIC replacements and alternative package options (SOT-23-5, 6-WLP) that require design modification or adapter solutions.

Parameter Comparison

Engineering Selection Recommendations

Direct Package Replacement (8-SOIC):

TLV3701IDBVR is the primary equivalent substitute for TLV3701IDR. Both devices share identical electrical specifications, including supply voltage range (2.7V ~ 16V), input offset voltage (5mV @ 15V), input bias current (250pA @ 15V), and CMRR/PSRR performance (88dB/105dB). The TLV3701IDBVR is in Active product status with significantly higher inventory availability (36,900 pcs vs. 842 pcs), making it the preferred choice for design transitions. The only difference is packaging format: TLV3701IDR is supplied in Tape & Reel (TR), while TLV3701IDBVR is supplied in Cut Tape (CT) & Digi-Reel®. Both maintain ROHS3 compliance and MSL 1 rating.

MAX987ESA+T and MAX985ESA+ are alternative 8-SOIC options from Analog Devices Inc./Maxim Integrated. Both feature TTL-compatible output stages and are in Active product status. However, these devices operate within a narrower supply voltage range (2.5V ~ 5.5V single, ±1.25V ~ 2.75V dual), which restricts their use to applications not requiring the extended 16V supply capability of the TLV3701IDR. MAX987ESA+T offers superior propagation delay performance (210ns) and higher inventory (4,568 pcs). MAX985ESA+ provides lower quiescent current (24µA vs. 96µA) but reduced inventory availability (953 pcs).

Alternative Package Options:

MCP6561UT-E/OT (Microchip Technology, SOT-23-5) operates across 1.8V ~ 5.5V supply range with extended operating temperature support (-40°C ~ 125°C). This device requires PCB layout modification due to different pin configuration and package footprint. Input offset voltage is 10mV (higher than TLV3701IDR), and quiescent current is 130µA. Propagation delay is 80ns. High inventory availability (23,100 pcs) supports rapid design transitions.

MAX9025EBT+T (Analog Devices Inc./Maxim, 6-WLP) integrates an internal voltage reference, differentiating it from standard comparator functionality. Supply range is 1.8V ~ 5.5V with operating temperature limited to -40°C ~ 85°C. This package requires specialized PCB design and assembly considerations. Quiescent current is 2.2µA, and propagation delay is 28µs. This device is suitable only for applications where integrated voltage reference functionality provides design advantage.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory compatibility with the original TLV3701IDR. Product status transitions from Last Time Buy to Active across all substitutes, ensuring long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can TLV3701IDBVR directly replace TLV3701IDR without circuit modification?

A: Yes. TLV3701IDBVR is electrically and functionally identical to TLV3701IDR. Both devices share the same pin configuration, electrical specifications, and operating characteristics. The only difference is packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel). No circuit modification is required for direct substitution.

Q: Why do MAX987ESA+T and MAX985ESA+ have narrower supply voltage ranges?

A: MAX987ESA+T and MAX985ESA+ are optimized for standard 5V and dual ±2.75V supply applications. These devices do not support the extended 16V single-supply or ±8V dual-supply capability of the TLV3701IDR. Selection of these alternatives is appropriate only for applications operating within the 2.5V ~ 5.5V range.

Q: Is MCP6561UT-E/OT a pin-compatible replacement?

A: No. MCP6561UT-E/OT uses SOT-23-5 packaging, which has a different pin count and footprint compared to the 8-SOIC package of TLV3701IDR. PCB layout and schematic modifications are required. This device is suitable for new designs or redesigns where package size reduction is beneficial.

Q: What is the significance of the voltage reference integrated into MAX9025EBT+T?

A: MAX9025EBT+T includes an internal voltage reference, enabling single-chip comparator-with-reference functionality. This integration reduces component count in applications requiring precision voltage comparison against a fixed reference. However, this feature is not present in the TLV3701IDR, making MAX9025EBT+T suitable only for designs where this additional functionality provides system-level advantage.

Q: Which substitute part offers the best inventory availability?

A: MCP6561UT-E/OT has the highest inventory availability at 23,100 pcs, followed by TLV3701IDBVR at 36,900 pcs. Both devices support rapid procurement for production ramp-up. MAX9025EBT+T offers 2,342 pcs, while MAX987ESA+T provides 4,568 pcs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—TLV3701IDBVR, MAX987ESA+T, MAX985ESA+, MCP6561UT-E/OT, and MAX9025EBT+T—maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory compatibility with the original TLV3701IDR.

Q: What is the operating temperature limitation for MAX9025EBT+T?

A: MAX9025EBT+T operates across -40°C ~ 85°C, which is narrower than the TLV3701IDR range of -40°C ~ 125°C. This device is not suitable for applications requiring operation above 85°C.

Q: How does input offset voltage differ across substitute parts?

A: TLV3701IDR and TLV3701IDBVR both specify 5mV input offset voltage. MAX987ESA+T, MAX985ESA+, and MAX9025EBT+T also specify 5mV. MCP6561UT-E/OT specifies 10mV, which may impact precision in applications with tight offset voltage requirements.
