LM25010MH Equivalent & Substitute Parts

Part Overview

The LM25010MH is a buck switching regulator IC from Texas Instruments designed for positive adjustable output applications. It delivers 1A output current with an adjustable voltage range from 2.5V to 37V, suitable for step-down conversion from input voltages between 6V and 42V. The LM25010MH is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM25010MH is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Input voltage range (6V–42V), output voltage range (2.5V–37V), output current (1A), and switching frequency (100kHz–1MHz) must be identical
• Topology & Configuration: Buck topology with positive adjustable single output
• Package & Mounting: 14-PowerTSSOP surface mount package with identical physical dimensions
• Synchronous Rectifier: No synchronous rectifier in all equivalent parts
• Moisture Sensitivity: MSL 1 (Unlimited) across all variants

The LM25010MH/NOPB and LM25010Q0MH/NOPB meet all electrical and mechanical requirements for direct substitution. Both are active products from Texas Instruments with identical base specifications. The LM25010Q0MH/NOPB includes automotive-grade qualification (AEC-Q100) and extended operating temperature range (-40°C to 150°C), making it suitable for automotive and high-temperature applications.

Parameter Comparison

Engineering Selection Recommendations

LM25010MH/NOPB is the direct active equivalent for standard industrial applications. It maintains identical electrical specifications and package form factor while offering ROHS3 compliance and active product status. This part is suitable for replacement in existing designs requiring the standard operating temperature range of -40°C to 125°C.

LM25010Q0MH/NOPB is the appropriate selection for automotive applications and high-temperature environments. It includes AEC-Q100 automotive qualification and extends the operating temperature range to 150°C, meeting automotive-grade reliability requirements. ROHS3 compliance is maintained. This variant is specified when designs require automotive-grade components or operation beyond 125°C.

Both substitute parts are pin-compatible and functionally equivalent to the obsolete LM25010MH, with no design modifications required for direct substitution within the specified electrical and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can LM25010MH/NOPB directly replace LM25010MH in existing designs?

A: Yes. The LM25010MH/NOPB is electrically and mechanically identical to the LM25010MH. It maintains the same input/output voltage ranges, output current, switching frequency, and 14-PowerTSSOP package. The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.

Q: What is the difference between LM25010MH/NOPB and LM25010Q0MH/NOPB?

A: Both parts are electrically equivalent with identical input/output specifications and package form factor. The LM25010Q0MH/NOPB differs in two aspects: (1) it is automotive-grade with AEC-Q100 qualification, and (2) it supports an extended operating temperature range of -40°C to 150°C compared to -40°C to 125°C for the standard variant. Select the automotive variant for designs requiring automotive qualification or operation above 125°C.

Q: Are all three parts in the same package?

A: Yes. All three parts use the 14-PowerTSSOP package with identical physical dimensions (0.173" width, 4.40mm). They are pin-compatible and require no PCB layout modifications for substitution.

Q: Why is the LM25010MH marked as obsolete?

A: The LM25010MH is classified as obsolete by Texas Instruments. Active equivalents (LM25010MH/NOPB and LM25010Q0MH/NOPB) are available for new designs and production continuity. Existing inventory of the obsolete part may be limited.

Q: Which part should I specify for a new design?

A: For standard industrial applications, specify LM25010MH/NOPB. For automotive applications or designs requiring operation above 125°C, specify LM25010Q0MH/NOPB. Both are active products with full availability and ROHS3 compliance.

Q: Are there any electrical performance differences between the three parts?

A: No. All three parts have identical electrical specifications: 6V–42V input range, 2.5V–37V adjustable output, 1A output current, and 100kHz–1MHz switching frequency. Differences are limited to product status, compliance certifications, temperature range, and automotive qualification.
