TLV70031DSER Equivalent & Substitute Parts

Part Overview

The TLV70031DSER is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 3.1V at 200mA with a maximum dropout voltage of 0.25V. The device is actively produced and widely used in applications requiring low-noise, low-quiescent-current voltage regulation in compact form factors. Finding equivalent and substitute parts is necessary for supply chain continuity, design flexibility, and inventory management across manufacturing and development environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TLV70031DSER is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 3.1V fixed positive output
• Output current capability: 200mA minimum
• Input voltage tolerance: 5.5V maximum
• Dropout voltage performance: 0.25V @ 200mA
• Package form factor: 6-WSON (1.5x1.5)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 125°C
• Protection feature set: Over Current, Over Temperature, Reverse Polarity, Under Voltage Lockout (UVLO)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The TLV70031DSET meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, thermal performance, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the TLV70031DSER and TLV70031DSET are active products from Texas Instruments with identical electrical and thermal specifications. Selection between these parts is based on packaging designation and supply availability. The TLV70031DSER is supplied in Tape & Reel (TR) format with 3430 units currently in stock, while the TLV70031DSET is also supplied in Tape & Reel (TR) format with 2264 units in stock. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The choice between these equivalents depends on procurement lead times, inventory levels, and specific supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can TLV70031DSET be used as a direct replacement for TLV70031DSER?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, dropout voltage, operating temperature range, and protection features. They share the same 6-WSON (1.5x1.5) package and mounting type.

Q: What is the difference between TLV70031DSER and TLV70031DSET?

A: The primary difference is the packaging designation suffix. Both parts are supplied in Tape & Reel (TR) format and are functionally identical. The suffix variation reflects different tape and reel configurations or manufacturing batches from Texas Instruments.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status, REACH unaffected designation, and regulatory certifications. They are suitable for the same applications and regulatory environments.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: output voltage (3.1V), output current (200mA), input voltage tolerance (5.5V max), dropout voltage (0.25V @ 200mA), package type (6-WSON 1.5x1.5), operating temperature range (-40°C ~ 125°C), and protection feature set.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the circuit design accommodates the 6-WSON (1.5x1.5) surface mount package and the specified electrical parameters. No design modifications are required for direct substitution.
