LM2575HVT-15/LB03 Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments LM2575HVT-15/LB03 is a fixed 15V, 1A Buck Switching Regulator IC in a TO-220-5 through-hole package, classified under Power Management (PMIC). It is part of the SIMPLE SWITCHER® series and functions as a step-down regulator with a positive, fixed output. As the LM2575HVT-15/LB03 is obsolete, it is critical to identify functionally and mechanically compatible alternatives for ongoing production maintenance and field service requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute components are selected based on strict matching or exceeding of the following key functional parameters: output voltage, output current, topology, switching frequency, input voltage range, fixed output type, package, mounting type, and environmental compliance (RoHS, REACH). Only parts explicitly listed below, and with specified compatible parameters, are considered.

Parameter Comparison

Engineering Selection Recommendations

Choose substitute parts for LM2575HVT-15/LB03 by confirming product status (prefer active where available), RoHS compliance, and REACH status. Both LM2575HVT-15/NOPB and LM2575HVT-15/LF03 are ROHS3 Compliant, REACH Unaffected, and listed as Active, which aligns with standard environmental and availability requirements. Mechanical compatibility with the TO-220-5 package and equivalent electrical parameters is present in all listed substitutes.

Frequently Asked Questions (FAQ)

Q1: What are the main parameters for choosing a substitute for the LM2575HVT-15/LB03 Buck Regulator?
A1: Key parameters are output voltage (15V fixed), output current (≥1A), input voltage range (minimum 4V/maximum 60V or greater), topology (buck), output type (fixed), package (TO-220-5 formed leads or equivalent), mounting type (through-hole), operating temperature, and compliance with ROHS3 and REACH.

Q2: Is the package and pinout of LM2575HVT-15/NOPB compatible with LM2575HVT-15/LB03?
A2: LM2575HVT-15/NOPB uses the TO-220-5 package and matches the form factor and pinout required for a direct replacement.

Q3: Are the substitute parts RoHS and REACH compliant?
A3: All listed substitutes are ROHS3 Compliant and REACH Unaffected.

Q4: Is there any difference in output type or regulation topology among the listed substitutes?
A4: All substitutes maintain a fixed 15V positive output using a buck topology.

Q5: Can LM2576TV-015G be used as a substitute for LM2575HVT-15/LB03?
A5: LM2576TV-015G meets the fixed 15V output, buck topology, and TO-220-5 formed leads package requirements, offering a higher output current specification and a reduced input voltage range (7V to 40V). All other primary electrical and mechanical attributes are compatible.
