TLV3402ID General Purpose Comparator Equivalent & Substitute Parts

Part Overview

The TLV3402ID is a dual-channel general purpose comparator manufactured by Texas Instruments in 8-SOIC surface mount packaging. This device features CMOS open-drain output architecture with wide supply voltage range (2.7V to 16V single supply, ±1.35V to ±8V dual supply) and low input offset voltage of 3.6mV at 15V. The TLV3402ID is designated as Last Time Buy status, making identification of functionally equivalent alternatives necessary for design continuity and long-term component availability.

Substitute Part Grouping Explanation

Substitution of the TLV3402ID is determined by the following critical parameters: dual-channel configuration (2 elements), CMOS open-drain output type, 8-SOIC package footprint, and supply voltage compatibility. Substitute parts are grouped into two categories:

Direct Functional Equivalents (Packaging Variant): Parts maintaining identical electrical specifications and dual-channel architecture with only packaging format differences (Tube vs. Tape & Reel).

Electrical Equivalents (Extended Supply Range): Parts with dual-channel configuration, CMOS open-drain output, and 8-SOIC package that operate within overlapping supply voltage ranges. These parts may exhibit different propagation delay, quiescent current, or input offset voltage characteristics but remain functionally compatible in applications where the TLV3402ID supply voltage range is not fully utilized.

Parametric Equivalents (Single Channel): Parts with identical electrical performance characteristics but single-channel configuration, suitable only for applications requiring one comparator channel.

Engineering Selection Recommendations

Primary Recommendation: TLV3402IDR is the direct functional equivalent of TLV3402ID, differing only in packaging format (Tape & Reel vs. Tube). This part maintains identical electrical specifications and is in Active product status, providing the most straightforward replacement path. Both parts are ROHS3 compliant and carry identical REACH and ECCN classifications.

Secondary Recommendations for Extended Supply Range Applications: MAX992ESA+T and MAX992ESA+ are suitable for applications operating within the 2.5V to 5.5V supply range. These parts offer faster propagation delay (210ns vs. 300µs) and are in Active status. However, they do not support the full extended supply voltage range of the TLV3402ID (up to ±8V dual supply).

Alternative for Low-Temperature Operation: MCP6567-E/SN operates across the full temperature range (-40°C to 125°C) matching the TLV3402ID and supports lower supply voltages (1.8V minimum). This part is in Active status and ROHS3 compliant. Propagation delay is significantly faster at 80ns.

Parametric Equivalent (Single Channel): TLV3401ID provides identical electrical performance to TLV3402ID but with single-channel configuration. This part is suitable only for applications requiring one comparator channel and is designated Last Time Buy status.

Not Recommended for Direct Substitution: ALD2303ASAL and ALD2303SAL operate only to 0°C minimum temperature and 70°C maximum, which does not meet the full operating range of the TLV3402ID. These parts are suitable only for applications with restricted temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can TLV3402IDR be used as a direct replacement for TLV3402ID?

A: Yes. TLV3402IDR is electrically identical to TLV3402ID. The only difference is packaging format: TLV3402ID is supplied in Tube packaging while TLV3402IDR is supplied in Tape & Reel format. Both parts are ROHS3 compliant and carry identical electrical specifications.

Q: What is the key difference between TLV3402ID and MAX992ESA+?

A: The primary differences are supply voltage range and propagation delay. TLV3402ID supports 2.7V to 16V single supply (±1.35V to ±8V dual), while MAX992ESA+ supports only 2.5V to 5.5V single supply (±1.25V to ±2.75V dual). MAX992ESA+ has faster propagation delay (210ns vs. 300µs). MAX992ESA+ is suitable only for applications operating within its narrower supply voltage range.

Q: Why is TLV3402ID designated Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product. Existing inventory is available for purchase, but no future production is planned. Customers should transition to active alternatives such as TLV3402IDR or other substitute parts for new designs.

Q: Can MCP6567-E/SN replace TLV3402ID in all applications?

A: MCP6567-E/SN is compatible with TLV3402ID in applications operating within the overlapping supply voltage range (2.7V to 5.5V). The MCP6567-E/SN offers faster propagation delay (80ns) and operates across the full temperature range (-40°C to 125°C). However, it does not support the extended supply voltage range above 5.5V or below 2.7V that TLV3402ID provides.

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

A: Tube packaging supplies components in a plastic tube suitable for manual handling and small-quantity applications. Tape & Reel packaging supplies components on continuous tape wound on a reel, optimized for automated assembly equipment. Electrical specifications are identical; packaging choice depends on manufacturing process requirements.

Q: Is TLV3401ID a suitable substitute for TLV3402ID?

A: TLV3401ID is a parametric equivalent with identical electrical performance but single-channel configuration compared to the dual-channel TLV3402ID. It is suitable only for applications requiring one comparator channel. Both parts are Last Time Buy status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry REACH Unaffected status, matching the compliance profile of TLV3402ID.
