LM2597HVM-5.0 Equivalent & Substitute Parts

Part Overview

The LM2597HVM-5.0 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 5V output and 500mA current capacity. This component operates across a wide input voltage range of 4.5V to 60V and is housed in an 8-SOIC surface mount package.

The LM2597HVM-5.0 is classified as obsolete, which necessitates identification of equivalent substitute components for new designs and ongoing production requirements. The active product variant with improved compliance status provides a direct path for component selection in current applications.

Substitute Part Grouping Explanation

Substitution for the LM2597HVM-5.0 is determined by strict equivalence across the following critical parameters:

• Input voltage range: 4.5V to 60V
• Fixed output voltage: 5V
• Output current capacity: 500mA
• Switching frequency: 150kHz
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Topology: Buck (step-down)
• Output configuration: Single positive output
• Operating temperature range: -40°C to 125°C

The LM2597HVM-5.0/NOPB represents the direct equivalent substitute, maintaining identical electrical specifications and mechanical compatibility while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The LM2597HVM-5.0/NOPB is the direct substitute for the obsolete LM2597HVM-5.0. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

The primary distinction is product status and regulatory compliance. The LM2597HVM-5.0/NOPB is classified as active and carries ROHS3 compliance certification, whereas the original LM2597HVM-5.0 is obsolete and RoHS non-compliant. For new designs and ongoing production, the LM2597HVM-5.0/NOPB is the appropriate selection.

Both components maintain identical moisture sensitivity levels (MSL 1 - Unlimited) and share the same REACH and ECCN classifications, ensuring equivalent handling and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the LM2597HVM-5.0/NOPB be used as a direct replacement for the LM2597HVM-5.0?

A: Yes. The LM2597HVM-5.0/NOPB is electrically and mechanically identical to the LM2597HVM-5.0. Both components feature the same input voltage range (4.5V to 60V), fixed 5V output, 500mA current capacity, 150kHz switching frequency, and 8-SOIC package. No circuit modifications are required.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" suffix indicates the component is supplied without lead (Pb), reflecting RoHS3 compliance. This designation distinguishes the active product variant from the obsolete original part number.

Q: Are there any differences in thermal or operating characteristics?

A: No. Both components operate across the identical temperature range of -40°C to 125°C (TJ) and share the same thermal and electrical performance specifications.

Q: What packaging options are available for the substitute part?

A: The LM2597HVM-5.0/NOPB is supplied in Tube packaging, whereas the original LM2597HVM-5.0 packaging specification was not provided. Both use the 8-SOIC (0.154", 3.90mm Width) surface mount package for the die itself.

Q: Are moisture sensitivity or handling requirements different between the two parts?

A: No. Both components carry MSL 1 (Unlimited) classification, indicating identical moisture sensitivity levels and handling requirements.
