Key Parameters

Substitute Part Grouping Explanation

Substitution of the BTS740S2NT is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Output current rating (4.9A), on-state resistance (27mOhm), load voltage range (5V ~ 34V), and output configuration (high-side N-Channel with 1:1 ratio)
• Functional Features: Status flag output, fault protection mechanisms (current limiting, open load detection, over-temperature, over-voltage)
• Interface Characteristics: On/off control with non-inverting input type
• Package Compatibility: 20-SOIC surface mount package with identical pinout and mechanical dimensions
• Automotive Compliance: AEC-Q100 qualification and automotive-grade designation
• Thermal Performance: Operating temperature range of -40°C to 150°C (junction temperature)

Substitute parts must match all these parameters without deviation to ensure direct replacement capability in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The BTS740S2XUMA1 is the direct parametric equivalent for the obsolete BTS740S2NT. Both components are manufactured by Infineon Technologies within the PROFET® series and share identical electrical, functional, and mechanical specifications.

The primary distinction is product status: BTS740S2NT is obsolete, while BTS740S2XUMA1 maintains active production status. The BTS740S2XUMA1 carries ROHS3 compliance certification, meeting current environmental regulatory requirements. Both components maintain AEC-Q100 automotive qualification and identical package specifications (20-SOIC surface mount).

For new designs or ongoing production requiring this power switch topology, the BTS740S2XUMA1 is the appropriate selection due to its active availability and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can BTS740S2XUMA1 be used as a direct replacement for BTS740S2NT?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including output current (4.9A), on-state resistance (27mOhm), load voltage range (5V ~ 34V), package type (20-SOIC), and automotive qualification (AEC-Q100). No circuit modifications are required.

Q: What is the difference between BTS740S2NT and BTS740S2XUMA1?

A: The primary differences are product status and packaging format. BTS740S2NT is obsolete; BTS740S2XUMA1 is active production. BTS740S2XUMA1 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats and carries ROHS3 compliance certification. All electrical and functional specifications are identical.

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

A: No. Both components operate across the identical temperature range (-40°C to 150°C junction temperature), maintain the same on-state resistance (27mOhm), and include identical fault protection mechanisms (current limiting, open load detection, over-temperature, over-voltage protection).

Q: Is the 20-SOIC package pinout identical between both parts?

A: Yes. Both components use the 20-SOIC (0.295", 7.50mm width) package with identical pinout and mechanical dimensions, enabling direct PCB-level substitution without layout modifications.

Q: Does BTS740S2XUMA1 meet automotive qualification requirements?

A: Yes. BTS740S2XUMA1 maintains AEC-Q100 qualification and automotive-grade designation, identical to the original BTS740S2NT specification.
