LM2575HVM-5.0/NOPB Equivalent & Substitute Parts

Part Overview

The LM2575HVM-5.0/NOPB is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 5V output and 1A output current capability. The device operates across a 4V to 60V input range and is housed in a 24-SOIC surface mount package. This part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2575HVM-5.0/NOPB is determined by strict alignment across the following parameters: buck topology, 5V fixed output voltage, 1A output current, 52kHz switching frequency, 24-SOIC package configuration, surface mount mounting type, and -40°C to 125°C operating temperature range. All identified substitutes maintain these core electrical and mechanical specifications. Variations in input voltage maximum rating, packaging format (tube vs. tape & reel), product status, and moisture sensitivity level are secondary considerations that do not affect functional equivalence within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The LM2575HVMX-5.0/NOPB from Texas Instruments is the direct successor within the same manufacturer's product line, maintaining identical electrical specifications and the same 24-SOIC package. This part carries active product status and is available in tape & reel packaging format, suitable for automated assembly environments.

The LM2575-5.0YWM and LM2575-5.0YWM-TR from Microchip Technology are functionally equivalent alternatives that meet all core electrical and mechanical requirements. Both parts are active products with ROHS3 compliance. The primary design consideration is the reduced maximum input voltage rating of 40V compared to the original 60V specification. Selection between tube (LM2575-5.0YWM) and tape & reel (LM2575-5.0YWM-TR) packaging depends on production volume and assembly methodology.

All substitute parts maintain the same switching frequency, output current capability, operating temperature range, and package footprint, ensuring direct functional replacement within applications where the 40V input maximum is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the LM2575-5.0YWM be used as a direct replacement for the LM2575HVM-5.0/NOPB?

A: Yes, the LM2575-5.0YWM is functionally equivalent for applications with input voltages up to 40V. If your design requires the full 60V input capability of the original part, the LM2575HVMX-5.0/NOPB from Texas Instruments is the appropriate choice.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging is suitable for manual assembly and lower-volume production. Tape & reel packaging is designed for automated pick-and-place assembly equipment and higher-volume manufacturing. Both formats contain identical die and electrical performance.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts are ROHS3 compliant, matching the compliance status of the original LM2575HVM-5.0/NOPB.

Q: What does the MSL (Moisture Sensitivity Level) rating indicate?

A: MSL rating specifies the maximum time a component can be exposed to moisture and temperature conditions before soldering. MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. MSL 2 and MSL 3 require controlled storage conditions. For most applications, this difference does not affect component selection unless specific moisture control protocols are mandated.

Q: Why is the input voltage maximum different for Microchip parts?

A: The Microchip LM2575-5.0YWM and LM2575-5.0YWM-TR variants are rated for a maximum 40V input, compared to 60V for the Texas Instruments versions. This reflects different design margins and testing protocols between manufacturers. Selection should be based on your actual input voltage requirements.

Q: Can I mix different substitute parts in the same production run?

A: All listed parts are electrically and mechanically equivalent within their specified operating ranges. However, maintaining consistent sourcing from a single manufacturer and part number is recommended for supply chain traceability and quality assurance documentation.
