TL331MDBVTEP Equivalent & Substitute Parts

Part Overview

The TL331MDBVTEP is a general-purpose comparator IC manufactured by Texas Instruments, featuring open-collector, rail-to-rail output architecture in a SOT-23-5 surface mount package. This device operates across a wide supply voltage range of 2V to 36V (single/dual ±1V to ±18V) and maintains an active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this comparator category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL331MDBVTEP are qualified based on the following critical parameters:

• Supply voltage compatibility: 2V ~ 36V (single) and ±1V ~ 18V (dual) operation
• Output architecture: Open-collector configuration with rail-to-rail capability
• Package form factor: SOT-23-5 / SC-74A surface mount footprint
• Input offset voltage specification: Maximum 5mV to 8mV range
• Input bias current: Maximum 0.25µA to 0.4µA @ 5V
• Quiescent current: Maximum 700µA to 2.5mA
• Operating temperature: Overlap within specified ranges
• Compliance certifications: RoHS3, REACH Unaffected, EAR99 classification

The AP331AWG-7 from Diodes Incorporated meets these substitution criteria within the allowed parameter tolerances for general-purpose comparator applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between TL331MDBVTEP and AP331AWG-7 is determined by application-specific requirements and operational constraints:

TL331MDBVTEP is specified for applications requiring extended operating temperature range (-55°C to 125°C), lower quiescent current consumption (700µA maximum), and tighter input offset voltage specification (5mV maximum). This device is suitable for industrial and automotive environments with wide temperature excursions.

AP331AWG-7 is specified for applications operating within the 0°C to 70°C temperature range where higher quiescent current (2.5mA maximum) is acceptable. This substitute maintains identical supply voltage compatibility, output architecture, and package footprint. Both devices carry equivalent compliance certifications (RoHS3, REACH Unaffected, EAR99).

Selection should be based on circuit operating temperature requirements and power budget constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can AP331AWG-7 replace TL331MDBVTEP in all applications?

A: AP331AWG-7 is compatible for applications operating within 0°C to 70°C. Applications requiring -55°C to 125°C operation must use TL331MDBVTEP or equivalent devices rated for extended temperature ranges.

Q: Are the package footprints identical?

A: Yes. Both devices use SC-74A / SOT-753 surface mount packages with identical pin configurations and PCB footprint requirements.

Q: What is the difference in quiescent current between these parts?

A: TL331MDBVTEP specifies 700µA maximum quiescent current, while AP331AWG-7 specifies 2.5mA maximum. For low-power applications, TL331MDBVTEP is the preferred selection.

Q: Are both devices RoHS3 compliant?

A: Yes. Both TL331MDBVTEP and AP331AWG-7 are RoHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What output configurations do these comparators support?

A: Both devices feature open-collector, rail-to-rail output architecture, enabling direct interface with TTL, CMOS, DTL, ECL, and MOS logic families.

Q: Are the supply voltage ranges identical?

A: Yes. Both devices operate across 2V to 36V single supply or ±1V to ±18V dual supply configurations.
