Substitute Part Grouping Explanation

Substitution of the TLV3402IP is determined by the following critical parameters:

Functional Equivalence Criteria:

Dual-channel comparator configuration (Number of Elements = 2)
CMOS open-drain output type
Supply voltage range compatibility (minimum 2.7V to 16V single supply)
Input offset voltage specification (≤3.6mV @ 15V)
Input bias current specification (≤250pA @ 15V)
Output current capability (≥10mA typical)
Quiescent current specification (≤950nA maximum)
Common-mode rejection ratio and power supply rejection ratio (≥88dB CMRR, ≥105dB PSRR)
Operating temperature range (-40°C to 125°C)

Packaging and Mounting Considerations:

Through-hole 8-DIP package is the primary form factor
Surface-mount alternatives (8-SOIC, 8-MSOP) are functionally equivalent but require PCB redesign

Compliance Requirements:

ROHS3 compliance
REACH unaffected status
EAR99 export classification

Substitutes are grouped into two categories: manufacturer-recommended direct replacements (same base product with different packaging) and parametric equivalents (different manufacturer, different element count, requiring application-level verification).

Engineering Selection Recommendations

TLV3402IDR (Manufacturer-Recommended Substitute)

The TLV3402IDR is the direct functional equivalent of the TLV3402IP, manufactured by Texas Instruments with identical electrical specifications. The primary difference is packaging: 8-SOIC surface-mount versus 8-DIP through-hole. This substitute is suitable for new designs or PCB revisions that accommodate surface-mount technology. The TLV3402IDR maintains Active product status, ensuring long-term availability and supply chain stability. Both parts share identical compliance certifications (ROHS3, REACH unaffected, EAR99).

MCP6567T-E/MS (Manufacturer-Recommended Substitute)

The MCP6567T-E/MS is a Microchip Technology dual-channel comparator with CMOS open-drain output in 8-MSOP surface-mount packaging. This substitute exhibits different electrical characteristics: reduced supply voltage range (1.8V to 5.5V), higher input offset voltage (10mV @ 5.5V), superior input bias current (1pA @ 5.5V), higher output current capability (50mA typical), and significantly faster propagation delay (80ns versus 300µs). The MCP6567T-E/MS is suitable for applications operating within the 1.8V to 5.5V supply range where faster response time is beneficial. This part maintains Active product status and ROHS3 compliance.

TLV3401IP (Parametric Equivalent)

The TLV3401IP is a single-channel comparator variant from Texas Instruments with identical electrical specifications to the TLV3402IP except for element count (1 versus 2). This part is suitable only for applications requiring single-channel comparison. The TLV3401IP maintains the same 8-DIP through-hole package and operating characteristics. Product status is Last Time Buy, consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can I use TLV3402IDR as a direct replacement for TLV3402IP without circuit modifications?

A: The TLV3402IDR is electrically identical to the TLV3402IP. However, it requires PCB redesign because it uses 8-SOIC surface-mount packaging instead of 8-DIP through-hole. Pin-to-pin functionality is equivalent, but physical footprint and mounting method differ.

Q: Is the MCP6567T-E/MS suitable for my application using TLV3402IP?

A: The MCP6567T-E/MS is functionally equivalent only if your application operates within the 1.8V to 5.5V supply voltage range. The TLV3402IP supports 2.7V to 16V, a wider range. Additionally, the MCP6567T-E/MS has different electrical characteristics: higher input offset voltage (10mV versus 3.6mV), higher quiescent current (130µA versus 950nA), and faster propagation delay (80ns versus 300µs). Application-level verification is required.

Q: Why is the TLV3401IP listed as a substitute if it has only one comparator?

A: The TLV3401IP is a parametric equivalent, not a direct replacement. It is listed for applications that require only single-channel comparison. All other electrical specifications match the TLV3402IP. This part is suitable only if your design uses only one of the two comparator channels in the TLV3402IP.

Q: What is the difference between "MFR Recommended" and "Parametric Equivalent" substitutes?

A: MFR Recommended substitutes are direct functional equivalents with identical electrical specifications, differing only in packaging or mounting type. Parametric Equivalents have different element counts or electrical characteristics but maintain compatibility within specific application constraints. MFR Recommended substitutes require only packaging-level design changes, while Parametric Equivalents require application-level verification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The TLV3402IDR, MCP6567T-E/MS, and TLV3401IP are all ROHS3 compliant and REACH unaffected, matching the compliance status of the main part TLV3402IP.

Q: Which substitute should I choose for a new design?

A: For new through-hole designs, use TLV3402IDR if supply voltage range is 2.7V to 16V. For new surface-mount designs with supply voltage 1.8V to 5.5V and requiring faster response time, use MCP6567T-E/MS. For single-channel applications, use TLV3401IP. All three maintain Active or equivalent product status and full compliance certifications.
