BTS3134NXT Equivalent & Substitute Parts

Part Overview

The BTS3134NXT is a Power Management Integrated Circuit (PMIC) classified as a power switch/driver with N-channel output configuration. This component is designed for general-purpose switching applications requiring low-side output control with integrated fault protection. The BTS3134NXT operates at a maximum load voltage of 42V with a 3A output current capability and features current limiting, over-temperature, and over-voltage protection.

The BTS3134NXT is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BTS3134NXT is determined by strict equivalence across the following critical parameters:

• Output configuration (Low Side, N-Channel, 1:1 ratio)
• Maximum load voltage (42V)
• Maximum output current (3A)
• On-resistance specification (35mOhm typical)
• Fault protection features (Current Limiting, Over Temperature, Over Voltage)
• Operating temperature range (-40°C to 150°C)
• Package type (PG-SOT223-4 / TO-261-4, TO-261AA)
• Mounting type (Surface Mount)
• Interface type (On/Off)

The BTS3134NHUMA1 meets all these criteria and is classified as a parametric equivalent. This substitute maintains identical electrical and mechanical specifications while differing only in product status, packaging format, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The BTS3134NHUMA1 is the direct substitute for the obsolete BTS3134NXT. Both components are manufactured by Infineon Technologies and belong to the HITFET® series. The electrical and mechanical specifications are identical, ensuring functional compatibility in existing circuit designs.

The primary distinction is product status: the BTS3134NXT is obsolete, while the BTS3134NHUMA1 is active and currently in production. The BTS3134NHUMA1 carries RoHS3 compliance certification, meeting current environmental and regulatory requirements. The substitute is available in Tape & Reel (TR) packaging format, which is standard for production environments.

For new designs, repair operations, and production continuity, the BTS3134NHUMA1 is the appropriate selection. No circuit redesign or re-qualification is required due to complete parametric equivalence.

Frequently Asked Questions (FAQ)

Q: Can the BTS3134NHUMA1 be used as a direct replacement for the BTS3134NXT?

A: Yes. The BTS3134NHUMA1 is a parametric equivalent with identical electrical specifications, output configuration, current rating, voltage rating, on-resistance, fault protection features, operating temperature range, and package type. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substitution?

A: The BTS3134NXT is obsolete. The BTS3134NHUMA1 is the active equivalent from the same manufacturer and series, ensuring continued component availability and supply chain reliability.

Q: Are there packaging differences between these parts?

A: Both parts use the same physical package (PG-SOT223-4 / TO-261-4, TO-261AA). The BTS3134NXT is supplied in standard packaging, while the BTS3134NHUMA1 is supplied in Tape & Reel (TR) format, which is typical for production quantities.

Q: Do regulatory certifications differ?

A: The BTS3134NHUMA1 carries RoHS3 compliance certification. Both parts maintain REACH Unaffected status. The BTS3134NHUMA1 is classified under ECCN EAR99, while the BTS3134NXT is marked as obsolete.

Q: Are the thermal and electrical performance characteristics identical?

A: Yes. Both parts operate across the same temperature range (-40°C to 150°C junction temperature), maintain identical on-resistance (35mOhm typical), and provide the same fault protection mechanisms (current limiting, over-temperature, over-voltage protection).

Q: Is re-qualification required when switching to the BTS3134NHUMA1?

A: No re-qualification is necessary due to complete parametric equivalence. The substitute maintains all critical electrical and mechanical specifications of the original part.
