LM2575HVMX-5.0 Equivalent & Substitute Parts

Part Overview

The LM2575HVMX-5.0 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, delivering fixed 5V output at 1A with input voltage range of 4V to 60V. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The LM2575HVMX-5.0/NOPB represents the direct equivalent with active product status, while Microchip Technology's LM2575-5.0YWM and LM2575-5.0YWM-TR variants provide functionally compatible alternatives with different packaging and input voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2575HVMX-5.0 is determined by the following criteria:

Electrical Parameters (Must Match):

• Output voltage: 5V fixed
• Output current: 1A minimum
• Switching frequency: 52kHz
• Operating temperature range: -40°C to 125°C
• Topology: Buck (step-down)
• Output configuration: Positive

Mechanical Parameters (Must Match):

• Package type: 24-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount

Allowable Variations:

• Input voltage maximum: 40V (Microchip variants) is acceptable for applications not requiring the full 60V input range of the original part
• Packaging format: Tube, Tape & Reel (TR), or bulk configurations are interchangeable for component selection purposes
• RoHS compliance status: Substitutes may have improved compliance (ROHS3) compared to the obsolete original

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended for Obsolete Part Replacement): The LM2575HVMX-5.0/NOPB is the direct substitute for the obsolete LM2575HVMX-5.0. It maintains identical electrical specifications, input voltage range (4V to 60V), and package configuration while offering active product status and ROHS3 compliance. This part is suitable for all applications previously using the original part.

Alternative Substitutes (Microchip Technology): The LM2575-5.0YWM and LM2575-5.0YWM-TR are functionally equivalent alternatives from Microchip Technology. Both parts are active products with ROHS3 compliance and improved moisture sensitivity ratings (MSL 2 versus MSL 3). The primary limitation is the reduced maximum input voltage of 40V compared to the original 60V specification. These substitutes are appropriate for applications with input voltages not exceeding 40V.

Packaging Considerations:

• LM2575HVMX-5.0/NOPB: Tape & Reel format for automated assembly
• LM2575-5.0YWM: Tube packaging for manual or semi-automated processes
• LM2575-5.0YWM-TR: Tape & Reel format for automated assembly

Frequently Asked Questions (FAQ)

Q: Can the LM2575-5.0YWM replace the obsolete LM2575HVMX-5.0 in all applications? A: The LM2575-5.0YWM is electrically compatible for applications with input voltages up to 40V. If your design requires the full 60V input range, use the LM2575HVMX-5.0/NOPB instead.

Q: What is the difference between LM2575-5.0YWM and LM2575-5.0YWM-TR? A: Both parts are electrically identical. The difference is packaging format: LM2575-5.0YWM is supplied in Tube, while LM2575-5.0YWM-TR is supplied in Tape & Reel (TR). Select based on your assembly process requirements.

Q: Why does the LM2575HVMX-5.0/NOPB have a higher input voltage rating than the Microchip alternatives? A: The Texas Instruments LM2575HVMX-5.0/NOPB is rated for 60V maximum input, while Microchip's LM2575-5.0YWM variants are rated for 40V maximum. This reflects different design specifications between manufacturers for the same base product number.

Q: Are all substitute parts RoHS compliant? A: The LM2575HVMX-5.0 is RoHS non-compliant. The LM2575HVMX-5.0/NOPB and both Microchip variants (LM2575-5.0YWM and LM2575-5.0YWM-TR) are ROHS3 compliant.

Q: What does MSL rating mean, and why do the Microchip parts have a better rating? A: MSL (Moisture Sensitivity Level) indicates how long a component can be stored before soldering. The original part has MSL 3 (168 hours), while Microchip variants have MSL 2 (1 year), providing longer shelf life and greater handling flexibility.

Q: Can I use these parts interchangeably on the same PCB? A: Yes, all substitute parts use the same 24-SOIC package and pinout. They are mechanically and electrically interchangeable for PCB layout purposes, subject to the input voltage limitations noted above.
