BTS142DAKSA1 Equivalent & Substitute Parts

Part Overview

The BTS142DAKSA1 is an N-Channel power switch driver from Infineon Technologies' HITFET® series, designed for general-purpose low-side switching applications. This active product operates at a maximum load voltage of 42V with an output current capacity of 4.6A and features integrated fault protection including current limiting, over-temperature, and over-voltage protection. The device is housed in a TO-252-3 (DPAK) surface-mount package with a typical on-resistance of 23mOhm.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set, enabling flexible component sourcing while preserving circuit functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BTS142DAKSA1 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: N-Channel output type, 1:1 input-output ratio, low-side output configuration, 42V maximum load voltage, 4.6A maximum output current, and 23mOhm typical on-resistance
• Functional Features: General-purpose switch type with integrated auto-restart and fault protection (current limiting, over-temperature, over-voltage)
• Thermal Specifications: Operating temperature range of -40°C to 150°C (TJ)
• Mechanical Compatibility: TO-252-3 (DPAK) surface-mount package with identical pinout and footprint
• Compliance & Certification: ROHS3 compliance and MSL 1 rating

Substitute parts must maintain identical values across all these parameters. Packaging format differences (tube versus tape & reel) do not affect electrical or mechanical compatibility and represent valid substitution scenarios for different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

Both the BTS142DAKSA1 and BTS142DATMA1 are active products from Infineon Technologies with identical electrical specifications, thermal ratings, and fault protection capabilities. Selection between these parts is determined by procurement and assembly requirements rather than technical performance:

• BTS142DAKSA1 (Tube Packaging): Suitable for low-volume applications, prototype development, and manual assembly workflows where component quantities per order are limited.
• BTS142DATMA1 (Tape & Reel Packaging): Appropriate for high-volume production runs and automated pick-and-place assembly processes requiring continuous component feed.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard surface-mount assembly processes and environmental regulations. The identical TO-252-3 package footprint guarantees direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can BTS142DATMA1 replace BTS142DAKSA1 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tape & reel versus tube). No circuit modifications or PCB layout changes are required.

Q: What does the packaging format difference mean for assembly?

A: Tube packaging (DAKSA1) is used for manual component handling and lower-volume orders. Tape & reel packaging (DATMA1) is designed for automated assembly equipment and high-volume production. The components themselves are identical.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts have identical maximum load voltage (42V), output current (4.6A), on-resistance (23mOhm), and operating temperature range (-40°C to 150°C). Fault protection features and auto-restart functionality are identical.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both use the TO-252-3 (DPAK) package with identical pinout and mechanical dimensions. Direct substitution on existing PCBs is possible without layout modifications.

Q: Are compliance certifications the same for both parts?

A: Yes. Both parts are ROHS3 compliant with MSL 1 rating, meeting the same environmental and moisture sensitivity standards.
