BTS142DNT Equivalent & Substitute Parts

Part Overview

The BTS142DNT is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, specifically a power switch/driver with N-channel output configuration. This component functions as a general-purpose low-side switch rated for 4.6A maximum output current at 42V maximum load voltage. The BTS142DNT is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the BTS142DNT is determined by strict equivalence across the following critical parameters:

  • Electrical Performance: Output current rating (4.6A), load voltage rating (42V maximum), on-resistance (23mOhm typical), and fault protection features (current limiting, over-temperature, over-voltage)
  • Functional Architecture: Low-side N-channel configuration with 1:1 input-to-output ratio and non-inverting on/off interface
  • Physical Form Factor: TO-252-3 package (DPAK with 2 leads plus tab) for direct PCB compatibility
  • Thermal Specifications: Operating temperature range of -40°C to 150°C junction temperature
  • Series Compatibility: HITFET® series designation

The BTS142DATMA1 meets all these criteria as a parametric equivalent, with the primary distinction being product status (active versus obsolete) and packaging format (tape & reel versus bulk).

Engineering Selection Recommendations

The BTS142DATMA1 is the direct active equivalent for the obsolete BTS142DNT. Selection between these parts is determined by procurement and regulatory requirements:

Use BTS142DATMA1 for new designs and ongoing production due to active product status, ensuring long-term availability and supply chain continuity. This part carries ROHS3 compliance certification, meeting current environmental regulations.

BTS142DNT remains applicable only for legacy system maintenance where existing inventory is available and product status is not a constraint. The REACH Unaffected designation applies to both parts.

Both parts share identical electrical performance, thermal specifications, and physical form factor, enabling direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can BTS142DATMA1 replace BTS142DNT in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is possible without circuit modification or PCB rework.

Q: What is the difference between BTS142DNT and BTS142DATMA1? A: The primary differences are product status (obsolete versus active) and packaging format (bulk versus tape & reel). The BTS142DATMA1 also carries ROHS3 compliance certification. All electrical and thermal specifications are identical.

Q: Why is BTS142DNT classified as obsolete? A: Obsolete status indicates the manufacturer has discontinued production. The BTS142DATMA1 serves as the active replacement for ongoing procurement and new designs.

Q: Are there any pin or footprint differences between these parts? A: No. Both parts use the TO-252-3 package (DPAK with 2 leads plus tab, SC-63 designation), ensuring identical PCB footprints and pin assignments.

Q: What packaging options are available? A: BTS142DNT is supplied in bulk format. BTS142DATMA1 is supplied in tape & reel (TR) format, standard for automated assembly processes.

Q: Do these parts have the same thermal and electrical ratings? A: Yes. Both parts are rated for 4.6A maximum output current, 42V maximum load voltage, 23mOhm typical on-resistance, and -40°C to 150°C operating temperature range.

Q: Is ROHS3 compliance required for my application? A: ROHS3 compliance is mandatory for products sold in the European Union and many other markets. BTS142DATMA1 meets this requirement; BTS142DNT status is not specified.
