LM5010MH Buck Switching Regulator IC Equivalent & Substitute Parts

Part Overview

The LM5010MH is a buck switching regulator IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This device functions as a step-down converter with positive adjustable output, delivering 1A output current in a 14-PowerTSSOP surface mount package. The LM5010MH is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Substitute parts maintain functional equivalence while offering alternative availability, packaging options, and extended operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM5010MH is determined by the following critical parameters:

Functional Equivalence Parameters:

• Step-down (buck) topology with positive adjustable output
• Single output configuration
• Output voltage range: 2.5V to 70V
• Output current rating: 1A
• Switching frequency range: 100kHz to 1MHz
• No synchronous rectifier

Package & Mechanical Compatibility:

• 14-PowerTSSOP (0.173", 4.40mm Width) package
• Surface mount configuration
• Identical pin count and footprint

Compliance & Environmental:

• ROHS3 compliance
• MSL 1 rating (unlimited moisture sensitivity)
• REACH unaffected status

All substitute parts listed maintain these core parameters, ensuring direct functional and mechanical compatibility. Variations in input voltage range, operating temperature range, and product status are noted but do not preclude substitution within specified application conditions.

Parameter Comparison

Engineering Selection Recommendations

LM5010MH/NOPB is the manufacturer-recommended direct substitute. This part maintains identical electrical specifications and operating temperature range (-40°C to 125°C) as the original LM5010MH. The primary distinction is product status: LM5010MH/NOPB is Active, providing long-term availability and supply continuity. This part is suitable for direct replacement in existing designs without modification.

LM5010AMH/NOPB is an Active substitute offering extended operating temperature range (-40°C to 150°C) and reduced minimum input voltage (6V versus 8V). These characteristics make this part suitable for applications requiring lower input voltage operation or enhanced thermal performance. The part is available in Tube packaging.

LM5010AQ0MH/NOPB is an Active automotive-grade substitute qualified to AEC-Q100 standard. This part combines the extended operating temperature range (-40°C to 150°C) and reduced minimum input voltage (6V) of the LM5010AMH with automotive qualification. Selection of this part is appropriate for automotive applications or designs requiring automotive-grade component certification.

All substitute parts are ROHS3 compliant, MSL 1 rated, and maintain identical package configuration and pin compatibility with the original LM5010MH.

Frequently Asked Questions (FAQ)

Q: Can LM5010AMH/NOPB replace LM5010MH in all applications?

A: LM5010AMH/NOPB is functionally compatible with LM5010MH for applications operating within the overlapping parameter ranges. The key difference is minimum input voltage: LM5010AMH/NOPB operates at 6V minimum input, while LM5010MH requires 8V minimum. If your application operates above 8V input, both parts are interchangeable. If your application requires 6V to 8V input operation, only LM5010AMH/NOPB is suitable.

Q: What is the difference between LM5010AMH/NOPB and LM5010AQ0MH/NOPB?

A: Both parts share identical electrical specifications and operating temperature range (-40°C to 150°C). The distinction is automotive qualification: LM5010AQ0MH/NOPB is AEC-Q100 qualified for automotive applications, while LM5010AMH/NOPB is not. Select LM5010AQ0MH/NOPB for automotive designs; select LM5010AMH/NOPB for industrial or general-purpose applications.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the 14-PowerTSSOP (0.173", 4.40mm Width) surface mount package. PCB footprint and pin configuration are identical across all listed parts.

Q: Why is LM5010MH listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number. LM5010MH/NOPB, LM5010AMH/NOPB, and LM5010AQ0MH/NOPB are Active alternatives that provide equivalent or enhanced functionality with assured long-term availability.

Q: Do all substitute parts meet RoHS and REACH requirements?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is MSL 1 rating, and does it affect substitution?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. All listed parts share MSL 1 rating, ensuring identical moisture sensitivity characteristics and no impact on substitution decisions.
