TLC3702MDREP Equivalent & Substitute Parts

Part Overview

The TLC3702MDREP is a dual-channel general-purpose comparator manufactured by Texas Instruments, part of the LinCMOS™ series. This device operates as an active component in signal conditioning, threshold detection, and level-shifting applications. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter ranges. Alternatives may be required due to packaging availability, supply chain considerations, or specific application requirements for operating temperature range, supply voltage, or output characteristics.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Parameters:

Dual-channel configuration (2 elements)
8-pin surface-mount package (SOIC or equivalent footprint)
Supply voltage range overlap with 4V ~ 16V specification
Output type compatibility (CMOS, Push-Pull, or TTL capable)
Operating temperature range that encompasses or exceeds -55°C ~ 125°C
ROHS3 compliance and MSL 1 rating

Secondary Consideration Parameters:

Input offset voltage, input bias current, and quiescent current within acceptable application tolerances
Propagation delay characteristics suitable for timing-critical applications
CMRR performance for noise rejection requirements

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications with different packaging) and manufacturer-recommended alternatives (functionally equivalent with acceptable parameter variations for general-purpose applications).

Engineering Selection Recommendations

Parametric Equivalent (Identical Specifications): TLC3702MDR is a direct parametric equivalent to TLC3702MDREP, differing only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both maintain identical electrical performance across all specified parameters and operating conditions. Selection between these variants depends on procurement and assembly requirements.

Manufacturer-Recommended Alternatives:

MAX962 series (ESA+T, EUA+, EUA+T variants) from Analog Devices Inc./Maxim Integrated are suitable for applications operating within the 2.7V ~ 5.5V supply range. These devices feature lower input offset voltage (1.5mV) and reduced quiescent current (9mA) compared to the TLC3702MDREP. Operating temperature range is limited to -40°C ~ 85°C. Package options include 8-SOIC and 8-uMAX/uSOP configurations. All variants maintain ROHS3 compliance and MSL 1 rating.

NCS3402DR2G from onsemi provides extended supply voltage compatibility (2.5V ~ 16V) and superior PSRR performance (105dB). This device features open-drain output architecture, requiring external pull-up resistors. Quiescent current is significantly lower (640nA typical). Operating temperature range extends to -40°C ~ 125°C. ROHS3 compliant with MSL 1 rating.

TC75W56FU,LF and TC75W57FU,LF from Toshiba Semiconductor offer push-pull output configuration with extended supply voltage flexibility (1.8V ~ 7V single supply or ±0.9V ~ 4.6V dual supply). These devices are packaged in 8-SSOP format. Operating temperature range is -40°C ~ 85°C. Both maintain ROHS3 compliance and MSL 1 rating. TC75W57FU,LF exhibits higher quiescent current (400µA) compared to TC75W56FU,LF (40µA).

TS3702IPT from STMicroelectronics provides dual supply voltage operation (2.7V ~ 16V single or ±1.35V ~ 8V dual) with extended temperature range (-40°C ~ 125°C).

Frequently Asked Questions (FAQ)

Q: Can TLC3702MDR be used as a direct replacement for TLC3702MDREP? A: Yes. TLC3702MDR is a parametric equivalent with identical electrical specifications. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both are suitable for identical applications without circuit modification.

Q: What are the key differences between TLC3702MDREP and MAX962 series comparators? A: The primary differences are supply voltage range and operating temperature. TLC3702MDREP operates from 4V ~ 16V and -55°C ~ 125°C, while MAX962 variants operate from 2.7V ~ 5.5V and -40°C ~ 85°C. MAX962 devices feature lower input offset voltage (1.5mV versus 5mV) and reduced quiescent current (9mA versus 90µA). MAX962 is suitable for lower-voltage applications within the specified temperature range.

Q: Is NCS3402DR2G compatible with TLC3702MDREP in all applications? A: NCS3402DR2G shares the same 8-SOIC package footprint and dual-channel configuration. However, it features open-drain output architecture, requiring external pull-up resistors. This output type difference necessitates circuit redesign. NCS3402DR2G is suitable for applications requiring open-drain output and offers superior PSRR performance (105dB) and extremely low quiescent current (640nA typical).

Q: Can Toshiba TC75W56FU,LF or TC75W57FU,LF replace TLC3702MDREP? A: These devices are functionally equivalent dual-channel comparators with push-pull output. However, they are packaged in 8-SSOP format (different footprint from 8-SOIC) and operate within -40°C ~ 85°C temperature range. Operating temperature range is narrower than TLC3702MDREP (-55°C ~ 125°C). PCB layout modification is required due to package differences. These alternatives are suitable for applications not requiring extended low-temperature operation.

Q: What is the advantage of TS3702IPT over TLC3702MDREP? A: TS3702IPT from STMicroelectronics offers dual supply voltage operation (±1.35V ~ 8V) in addition to single supply (2.7V ~ 16V), providing greater flexibility for mixed-signal applications. Quiescent current is significantly reduced (25µA versus 90µA), resulting in lower power consumption. Operating temperature range extends to -40°C ~ 125°C. Input offset voltage specification matches TLC3702MDREP (5mV @ 10V). Package is 8-TSSOP format, requiring PCB layout modification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and storage requirements.

Q: Which substitute part offers the lowest power consumption? A: NCS3402DR2G from onsemi provides the lowest quiescent current at 640nA typical, making it the most power-efficient option. This device is suitable for battery-powered or ultra-low-power applications. Open-drain output architecture requires external pull-up resistors.

Q: Can I use MAX962EUA+ (Tube packaging) instead of MAX962EUA+T (Tape & Reel)? A: Yes. Both variants are electrically identical, differing only in packaging format. MAX962EUA+ is supplied in Tube packaging, while MAX962EUA+T is supplied in Tape & Reel format. Selection depends on assembly equipment compatibility and procurement requirements.
