Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM25005MHX is determined by strict equivalence across the following critical parameters:

• Identical buck topology and step-down function
• Matching output configuration (positive, adjustable)
• Identical voltage input range (7V to 42V)
• Identical output voltage range (1.225V to 37V minimum, 37V maximum)
• Identical output current rating (2.5A)
• Identical switching frequency range (50kHz ~ 500kHz)
• Identical package type (20-PowerTSSOP / 20-HTSSOP)
• Identical operating temperature range (-40°C ~ 125°C)
• Same base product number (LM25005)

Parts meeting all these criteria are considered direct functional and mechanical equivalents suitable for replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The LM25005MHX/NOPB is the direct substitute for the LM25005MHX. Both parts are electrically and mechanically identical across all functional parameters. The primary differences are product status and compliance certifications.

The LM25005MHX/NOPB is classified as active product status, ensuring continued manufacturer support and availability. It carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and manufacturing processes. The /NOPB suffix indicates lead-free plating and RoHS compliance.

For applications requiring RoHS compliance or long-term supply chain assurance, the LM25005MHX/NOPB is the preferred selection. Both parts are suitable for identical circuit implementations without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LM25005MHX/NOPB be used as a direct replacement for the LM25005MHX?
