LM2575HVT-5.0 Equivalent & Substitute Parts

Part Overview

The LM2575HVT-5.0 is a buck switching regulator IC from Texas Instruments, part of the SIMPLE SWITCHER® series. It delivers a fixed 5V output at 1A from input voltages ranging from 4V to 60V, operating across the industrial temperature range of -40°C to 125°C. The device is packaged in TO-220-5 and is currently in Last Time Buy status. Due to this product status, identifying equivalent and substitute parts ensures design continuity and supply chain reliability for applications requiring 5V buck regulation.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM2575HVT-5.0 is determined by the following critical parameters:

• Output Voltage & Current: 5V fixed output at 1A minimum
• Input Voltage Range: Minimum 4V input capability
• Package: TO-220-5 form factor
• Switching Frequency: 52kHz operation
• Temperature Range: -40°C to 125°C
• Topology: Buck (step-down) configuration
• Compliance: ROHS3 and REACH compliance

Substitute parts are grouped into two categories:

Direct Equivalents (1A Output): Parts with identical 5V/1A specifications and compatible input voltage ranges. These include the LM2575HVT-5.0/NOPB (Texas Instruments), LM2575-5.0WT (Microchip), and LM2575T-5G (onsemi).

Higher Current Alternatives (3A Output): Parts with 5V fixed output but 3A current capability, suitable for applications requiring additional headroom. These include the LM2576-5.0WT (Microchip) and LM2576T-005G (onsemi).

Extended Topology Options: The MIC4575-5.0WT offers buck-boost capability with 1.7A output, and the MIC4576-5.0WT provides 3A buck regulation, both from Microchip Technology.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement: The LM2575HVT-5.0/NOPB from Texas Instruments is the primary equivalent, maintaining identical electrical specifications and Active product status. This part is recommended when supply continuity from the original manufacturer is prioritized.

For Microchip Ecosystem Integration: The LM2575-5.0WT provides 1A output with Active status and full ROHS3 compliance. Note that maximum input voltage is limited to 40V compared to the original 60V specification.

For onsemi Supply Chain: The LM2575T-5G offers 1A output with Active status. The minimum input voltage is 4.75V, which may affect applications requiring operation below this threshold.

For Higher Current Margin: The LM2576-5.0WT (Microchip) and LM2576T-005G (onsemi) provide 3A output capability at 5V, suitable for designs requiring additional current headroom. The onsemi variant has a 7V minimum input voltage specification.

For Extended Input Range: The original LM2575HVT-5.0 supports 60V maximum input. Substitutes from Microchip and onsemi are limited to 40V maximum, requiring circuit redesign if higher input voltages are required.

For Higher Switching Frequency Applications: The MIC4575-5.0WT and MIC4576-5.0WT operate at 200kHz, enabling smaller external component sizing. These parts are suitable for space-constrained designs but operate to 85°C maximum, not 125°C.

All substitute parts maintain ROHS3 compliance and REACH compliance status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the LM2575HVT-5.0/NOPB be used as a direct replacement?

A: Yes. The LM2575HVT-5.0/NOPB is electrically and mechanically identical to the LM2575HVT-5.0, with the same 5V/1A output, 4V to 60V input range, and TO-220-5 package. The primary difference is Active product status versus Last Time Buy.

Q: What is the difference between 1A and 3A output variants?

A: The LM2575 series provides 1A output, while the LM2576 series provides 3A output. Both maintain 5V fixed output and 52kHz switching frequency. The 3A variants are suitable for applications requiring higher current capacity or design margin.

Q: Are there input voltage limitations when substituting with Microchip or onsemi parts?

A: Yes. The original LM2575HVT-5.0 supports 4V to 60V input. Microchip LM2575-5.0WT and LM2576-5.0WT are limited to 40V maximum. The onsemi LM2576T-005G has a 7V minimum input specification. Verify input voltage requirements before substitution.

Q: Can MIC4575 or MIC4576 parts replace the LM2575HVT-5.0?

A: The MIC4575-5.0WT and MIC4576-5.0WT are functionally compatible for 5V output applications but operate at 200kHz switching frequency and are rated to 85°C maximum temperature, not 125°C. These are suitable for space-constrained designs but not for high-temperature applications.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant and REACH Unaffected status consistent with the original LM2575HVT-5.0.

Q: What packaging options are available?

A: All parts listed are supplied in TO-220-5 package in Tube packaging format. No alternative package options are provided in this substitution list.

Q: Which substitute offers the best supply availability?

A: The MIC4576-5.0WT from Microchip Technology shows the highest inventory level at 9,014 pieces. The LM2575T-5G from onsemi provides 6,014 pieces. Inventory levels should be verified with current suppliers for real-time availability.
