Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM25007MM is determined by strict equivalence across the following critical parameters:

• Functional topology: Buck (step-down) switching regulator
• Output configuration: Positive adjustable
• Voltage specifications: Input 9V–42V, Output 2.5V–37V adjustable
• Current rating: 500mA output
• Switching frequency: Up to 800kHz
• Package type: 8-TSSOP/8-MSOP (0.118", 3.00mm Width)
• Thermal range: -40°C to 125°C (TJ)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The LM25007MM/NOPB qualifies as a direct substitute based on identical electrical specifications, package configuration, and thermal performance across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The LM25007MM/NOPB is a direct functional equivalent to the LM25007MM. Both devices share identical electrical specifications, package configuration, and thermal operating range. The primary distinction is product status: the original LM25007MM is in Last Time Buy status, while the LM25007MM/NOPB maintains Active status, ensuring continued availability and supply chain support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The LM25007MM/NOPB is suitable for new designs and ongoing production where supply continuity is required.

Frequently Asked Questions (FAQ)

Q: Can the LM25007MM/NOPB be used as a direct replacement for the LM25007MM?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including input/output voltage ranges, current rating, switching frequency, package type, and thermal specifications.

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

A: The "/NOPB" designation indicates the part is supplied without plumbum (lead-free), consistent with ROHS3 compliance requirements. This does not affect electrical or mechanical compatibility.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-TSSOP/8-MSOP package with 0.118" width and 3.00mm height. Pinout and footprint are identical.

Q: Why is the original LM25007MM in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The LM25007MM/NOPB, maintained in Active status by National Semiconductor, provides continuity for designs requiring this functional specification.

Q: Are there compliance or certification differences between the two parts?

A: No. Both parts carry identical ECCN (EAR99) and HTSUS classifications, and both maintain ROHS3 compliance and REACH unaffected status.
