Key Parameters

Substitute Part Grouping Explanation

Substitution of the BSP742TNT is determined by strict equivalence across the following critical parameters:

• Output configuration (High Side N-Channel)
• Input/Output ratio (1:1)
• Maximum output current (800mA)
• On-state resistance (260mOhm typical)
• Load voltage range (5V ~ 34V)
• Fault protection features (Current Limiting, Over Temperature, Over Voltage)
• Operating temperature range (-40°C ~ 150°C)
• Package type (8-SOIC, 0.154" width)
• Surface mount compatibility

The BSP742TXUMA1 meets all these electrical and mechanical requirements, providing direct functional equivalence to the obsolete BSP742TNT.

Parameter Comparison

Engineering Selection Recommendations

The BSP742TXUMA1 is the direct substitute for the obsolete BSP742TNT. Both components share identical electrical specifications and mechanical packaging, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The BSP742TXUMA1 offers the advantage of active product status with ROHS3 compliance, providing long-term availability and regulatory alignment for new designs or legacy system updates. The component maintains the same 8-SOIC package footprint, allowing direct PCB layout compatibility without redesign requirements.

Selection of the BSP742TXUMA1 is appropriate for applications requiring the specified 800mA output current, 5V to 34V load voltage range, and integrated fault protection features across the -40°C to 150°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the BSP742TXUMA1 be used as a direct replacement for the BSP742TNT?

A: Yes. The BSP742TXUMA1 provides complete electrical and mechanical equivalence to the BSP742TNT. All critical parameters including output current rating, on-state resistance, load voltage range, fault protection, operating temperature, and 8-SOIC package dimensions are identical.

Q: Are there any package differences between these parts?

A: Both components use the 8-SOIC (0.154", 3.90mm Width) package. The BSP742TNT specifies PG-DSO-8-24 as the supplier device package, while the BSP742TXUMA1 specifies PG-DSO-8-6. These designations refer to different tape and reel configurations for the same physical package, with no impact on PCB assembly or circuit functionality.

Q: What is the difference in product status between these parts?

A: The BSP742TNT is obsolete and no longer manufactured. The BSP742TXUMA1 is an active product with current manufacturing and distribution support. For new designs or system updates, the BSP742TXUMA1 is the appropriate selection.

Q: Does the BSP742TXUMA1 meet current regulatory requirements?

A: The BSP742TXUMA1 is ROHS3 compliant and carries REACH Unaffected status, meeting current environmental and regulatory standards for electronic components.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both components have MSL 3 (168 Hours) rating, requiring identical handling and storage protocols during manufacturing and assembly.
