TLV3402IDG4 Equivalent & Substitute Parts

Part Overview

The TLV3402IDG4 is a dual-channel general-purpose CMOS comparator with open-drain output, manufactured by Texas Instruments in 8-SOIC surface-mount packaging. This device operates across a wide supply voltage range (2.7V to 16V single supply, ±1.35V to ±8V dual supply) and is designed for precision voltage comparison applications requiring low input offset voltage and low input bias current.

The TLV3402IDG4 carries Last Time Buy status, indicating discontinued production. Equivalent substitutes are available in active production status with identical or superior electrical performance, making substitution necessary for new designs and long-term supply assurance.

Engineering Selection Recommendations

Recommended Primary Substitutes:

TLV3402IDR is the direct equivalent replacement. It maintains identical electrical specifications and 8-SOIC package footprint as the TLV3402IDG4, with the distinction of Tape & Reel packaging instead of Tube. This part is in Active production status with 27,578 units in stock, providing superior supply continuity. Selection of TLV3402IDR is appropriate for applications requiring no design modification.

TLV3402ID provides identical electrical performance in Tube packaging and Last Time Buy status. This option is suitable only if existing inventory must be consumed before transitioning to active-production alternatives.

Conditional Substitutes (Supply Voltage Dependent):

MAX992ESA+T and MAX992ESA+ are suitable only for applications operating within the 2.5V to 5.5V supply range. These devices offer faster propagation delay (210ns vs. 300µs) and lower input bias current (1pA vs. 250pA), with Active production status and high inventory availability. Substitution requires verification that the application supply voltage does not exceed 5.5V.

MAX990ESA+T and MAX990ESA+ are suitable only for applications operating within the 2.5V to 5.5V supply range. These devices feature the lowest quiescent current (24µA) among available substitutes, beneficial for battery-powered applications. Substitution requires verification that the application supply voltage does not exceed 5.5V and that the slower propagation delay (450ns) meets timing requirements.

Limited Substitutes (Restricted Operating Temperature):

ALD2303ASAL and ALD2303SAL are suitable only for applications with operating temperature range of 0°C to 70°C. These devices are not appropriate for applications requiring the full -40°C to 125°C temperature range of the TLV3402IDG4.

Parametric Equivalent (Single-Channel):

TLV3401ID is a single-channel variant with identical per-channel electrical specifications. This part is suitable only for applications requiring a single comparator channel, not as a direct replacement for dual-channel designs.

Frequently Asked Questions (FAQ)

Q: Can I use TLV3402IDR as a direct replacement for TLV3402IDG4?

A: Yes. TLV3402IDR is electrically and mechanically identical to TLV3402IDG4. The only difference is packaging format: TLV3402IDR is supplied in Tape & Reel (TR) format while TLV3402IDG4 is supplied in Tube format. Both use the same 8-SOIC footprint and are pin-compatible. TLV3402IDR is in Active production status with significantly higher inventory availability.

Q: Why do MAX992ESA+ and MAX990ESA+ have restricted supply voltage ranges?

A: The MAX992 and MAX990 series are optimized for low-voltage applications (2.5V to 5.5V supply). The TLV3402IDG4 supports extended supply voltage up to 16V single supply or ±8V dual supply. Substitution with MAX series devices is valid only if your application operates within the 2.5V to 5.5V range. Exceeding this voltage range will damage the device.

Q: What is the difference between ALD2303ASAL and ALD2303SAL?

A: Both are dual-channel comparators in 8-SOIC packaging from Advanced Linear Devices. The primary difference is quiescent current: ALD2303ASAL draws 40µA maximum while ALD2303SAL draws 100µA maximum. Both are restricted to 0°C to 70°C operating temperature and 3V to 10V supply voltage, making them unsuitable for applications requiring the full -40°C to 125°C range of the TLV3402IDG4.

Q: Can I use TLV3401ID to replace TLV3402IDG4?

A: TLV3401ID is a single-channel comparator with identical per-channel electrical performance. It is a parametric equivalent only for applications requiring one comparator channel. For dual-channel applications, TLV3401ID cannot replace TLV3402IDG4 without circuit redesign.

Q: Which substitute offers the fastest response time?

A: MAX992ESA+ and MAX992ESA+T offer the fastest propagation delay at 210ns, compared to 300µs for the TLV3402IDG4. However, this substitution is valid only for applications operating within 2.5V to 5.5V supply voltage range.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the TLV3402IDG4.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity applications. Tape & Reel (TR) packaging supplies components on continuous tape suitable for automated pick-and-place assembly equipment. Both formats use identical 8-SOIC footprints and are electrically equivalent. Selection depends on assembly process requirements.
