TLC3702MDR Equivalent & Substitute Parts

Part Overview

The TLC3702MDR is a dual-channel general-purpose comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This LinCMOS™ series device features CMOS push-pull TTL output architecture and operates across a wide supply voltage range of 4V to 16V. The part is currently in active production status with 19,212 units available in inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, packaging preferences, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC3702MDR is determined by the following critical parameters:

• Number of Elements: Must be 2 (dual comparators)
• Package / Case: Must be 8-SOIC form factor with 0.154" (3.90mm) width for direct PCB compatibility
• Mounting Type: Must be Surface Mount
• Output Type: Must support CMOS and TTL logic levels
• Voltage - Supply, Single/Dual (±): Operating range must encompass or exceed 4V ~ 16V
• Voltage - Input Offset (Max): Must not exceed 5mV specification
• Current - Input Bias (Max): Must not exceed 5pA specification
• Current - Output (Typ): Must provide minimum 20mA drive capability
• Operating Temperature: Must support -55°C ~ 125°C range

Substitute parts are classified into two categories: parametric equivalents (identical electrical specifications and packaging) and manufacturer-recommended alternatives (functionally equivalent with acceptable performance trade-offs).

Parameter Comparison

Engineering Selection Recommendations

TLC3702MDREP is the primary parametric equivalent, offering identical electrical specifications and operating characteristics to the TLC3702MDR. The only difference is packaging format: TLC3702MDREP is supplied in Tape & Reel (TR) format versus the original Cut Tape (CT) & Digi-Reel® format. Both maintain the same 8-SOIC package geometry and are fully pin-compatible. Selection between these two depends solely on procurement and assembly requirements.

MAX962EUA+ is a manufacturer-recommended alternative from Analog Devices Inc./Maxim Integrated. This device operates within a narrower supply voltage range (2.7V ~ 5.5V) compared to the TLC3702MDR (4V ~ 16V), making it unsuitable for applications requiring the full 4V ~ 16V supply range. However, it offers superior input offset voltage (1.5mV versus 5mV) and significantly faster propagation delay (7ns versus 4.5µs). The MAX962EUA+ is housed in an 8-TSSOP/8-MSOP package with 0.118" (3.00mm) width, requiring PCB layout modification. This part is suitable only for applications operating within the 2.7V ~ 5.5V supply window and where package size reduction is acceptable.

NCS3402DR2G is a manufacturer-recommended alternative from onsemi. This device supports the full supply voltage range (2.5V ~ 16V) and maintains 8-SOIC package compatibility. However, it features open-drain output architecture rather than push-pull CMOS output, requiring external pull-up resistors for TTL-level output. The NCS3402DR2G exhibits significantly lower quiescent current (640nA versus 90µA) and superior PSRR (105dB versus unspecified), but has reduced output drive capability (10mA versus 20mA) and substantially longer propagation delay (220µs typical versus 4.5µs maximum). Selection of this part requires circuit redesign to accommodate open-drain output topology.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and active product status.

Frequently Asked Questions (FAQ)

Q: Can TLC3702MDREP be used as a direct replacement for TLC3702MDR?

A: Yes. TLC3702MDREP is electrically and mechanically identical to TLC3702MDR. The only difference is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel). Both use the same 8-SOIC package with 0.154" (3.90mm) width and are fully pin-compatible. Selection depends on procurement and assembly line requirements.

Q: Is MAX962EUA+ a direct substitute for TLC3702MDR?

A: No. While MAX962EUA+ is a dual-channel general-purpose comparator, it has critical differences. The supply voltage range is limited to 2.7V ~ 5.5V, making it incompatible with applications requiring the full 4V ~ 16V range of the TLC3702MDR. Additionally, the MAX962EUA+ uses an 8-TSSOP/8-MSOP package (0.118" width) instead of 8-SOIC (0.154" width), requiring PCB layout changes. Use MAX962EUA+ only in applications operating within 2.7V ~ 5.5V supply range where package size reduction is acceptable.

Q: Can NCS3402DR2G replace TLC3702MDR in all applications?

A: No. NCS3402DR2G has open-drain output architecture, requiring external pull-up resistors to achieve TTL-level output. The TLC3702MDR has push-pull CMOS output that does not require pull-up resistors. Additionally, NCS3402DR2G has reduced output drive capability (10mA versus 20mA) and much longer propagation delay (220µs typical versus 4.5µs maximum). Use NCS3402DR2G only in applications where open-drain output is acceptable and propagation delay requirements are relaxed.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: dual-channel configuration (2 elements), 8-SOIC package form factor (0.154" width), surface-mount technology, supply voltage range compatibility, input offset voltage specification, input bias current specification, output drive capability, and operating temperature range. Any deviation in these parameters requires circuit redesign or application verification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLC3702MDREP, MAX962EUA+, and NCS3402DR2G are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts maintain active product status with established supply chains.

Q: What is the primary difference between TLC3702MDR and TLC3702MDREP?

A: The primary difference is packaging format. TLC3702MDR is supplied in Cut Tape (CT) & Digi-Reel® format, while TLC3702MDREP is supplied in Tape & Reel (TR) format. Electrical specifications, package geometry, and pin configuration are identical. Selection depends on assembly line compatibility and procurement preferences.

Q: Why does NCS3402DR2G have such low quiescent current compared to TLC3702MDR?

A: NCS3402DR2G uses open-drain output architecture, which inherently consumes less quiescent current (640nA) than the push-pull CMOS output of TLC3702MDR (90µA). This architectural difference makes NCS3402DR2G suitable for low-power applications but requires external pull-up resistors and circuit redesign.
