Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM2574HVMX-5.0 is determined by strict equivalence across the following critical parameters:

• Base product number (LM2574 series)
• Output voltage (Fixed 5V)
• Output current rating (500mA)
• Input voltage range (4V to 60V)
• Package type (14-SOIC)
• Switching topology (Buck converter)
• Operating temperature range (-40°C to 125°C)
• Mounting configuration (Surface Mount)

The LM2574HVMX-5.0/NOPB qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction lies in packaging format (Cut Tape vs. Tape & Reel) and product status (Last Time Buy vs. Active).

Parameter Comparison

Engineering Selection Recommendations

The LM2574HVMX-5.0/NOPB is the direct substitute for the LM2574HVMX-5.0. Both parts maintain identical electrical and thermal specifications, ensuring functional equivalence in circuit applications. The primary consideration is product status: the original part is Last Time Buy, while the substitute is Active, providing ongoing availability and supply chain continuity.

Selection between these parts should be based on procurement requirements. For new designs or long-term production, the LM2574HVMX-5.0/NOPB (Active status) is the appropriate choice. For existing inventory management or legacy system support, the LM2574HVMX-5.0 remains functionally equivalent until stock depletion.

Both parts comply with ROHS3 and REACH requirements, supporting regulatory compliance across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the LM2574HVMX-5.0/NOPB be used as a direct replacement for the LM2574HVMX-5.0?

A: Yes. Both parts are electrically and mechanically identical. They deliver the same 5V output at 500mA, accept identical input voltage ranges (4V to 60V), and use the same 14-SOIC package. The difference is packaging format and product status.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) is supplied in individual strips, while Tape & Reel (TR) is wound on reels for automated assembly. Both formats contain the same component. Selection depends on production volume and assembly equipment compatibility.

Q: Why is the original part marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of the LM2574HVMX-5.0. The LM2574HVMX-5.0/NOPB remains in active production and is the recommended part for future procurement.

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

A: No. Both parts operate across the same temperature range (-40°C to 125°C) and maintain identical switching frequency (52kHz) and output current capability (500mA).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LM2574HVMX-5.0 and LM2574HVMX-5.0/NOPB are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.
