LM2576HVT-5.0 Equivalent & Substitute Parts

Part Overview

The LM2576HVT-5.0 is a buck switching regulator IC from Texas Instruments, part of the SIMPLE SWITCHER® series. It delivers a fixed 5V output at 3A from input voltages ranging from 4V to 60V, operating across the industrial temperature range of -40°C to 125°C. The device is mounted in a TO-220-5 through-hole package and is ROHS3 compliant with MSL 1 rating.

The main part number LM2576HVT-5.0 carries a Last Time Buy status, indicating production discontinuation. Equivalent and substitute parts are available from multiple manufacturers with identical or compatible electrical and mechanical specifications, ensuring design continuity and supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2576HVT-5.0 is determined by the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (3A minimum)
• Input voltage range compatibility (minimum 4V, maximum 40V or higher)
• Package type (TO-220-5 through-hole)
• Switching frequency (52kHz)
• Operating temperature range (-40°C to 125°C)
• Regulatory compliance (ROHS3, REACH Unaffected)

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Specifications): Parts with matching output current (3A), input voltage range (4V to 60V or 4V to 40V), and all electrical parameters. These include LM2576HVT-5.0/LF02 and LM2576HVT-5.0/NOPB from Texas Instruments, and LM2576-5.0WT and LM2576T-005G from alternative manufacturers.

Functional Alternatives (Reduced Output Current): Parts with identical output voltage and topology but lower output current ratings (1A instead of 3A). These include LM2575-5.0WT and LM2575T-5G. These are suitable only for applications requiring 1A or less output current.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (3A Output Current Required):

LM2576HVT-5.0/NOPB (Texas Instruments) is the manufacturer-recommended direct equivalent with active product status and highest inventory availability (5770 pcs). This part maintains identical electrical specifications and TO-220-5 packaging.

LM2576HVT-5.0/LF02 (Texas Instruments) is an alternative direct equivalent with formed leads packaging, suitable for applications requiring lead forming during assembly.

LM2576-5.0WT (Microchip Technology) and LM2576T-005G (onsemi) are functionally equivalent alternatives from alternative manufacturers. Both maintain 3A output current and 52kHz switching frequency. Note that LM2576T-005G specifies a minimum input voltage of 7V, restricting its use in applications requiring operation below 7V input.

For Current-Limited Applications (1A Output Current Acceptable):

LM2575-5.0WT (Microchip Technology) and LM2575T-5G (onsemi) are suitable only for designs requiring 1A or less output current. Both maintain identical output voltage, switching frequency, and operating temperature range. Input voltage range is limited to 4V to 40V maximum.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory continuity. MSL ratings are consistent across all options (MSL 1 or Not Applicable), supporting standard moisture-controlled storage and handling.

Frequently Asked Questions (FAQ)

Q: Can LM2575-5.0WT or LM2575T-5G be used as direct replacements for LM2576HVT-5.0?

A: No. These parts are functional alternatives only for applications requiring 1A or less output current. The LM2575 series is rated for 1A maximum output, while the LM2576HVT-5.0 is rated for 3A. Using a 1A-rated device in a 3A application will result in thermal stress and potential device failure.

Q: What is the difference between LM2576HVT-5.0 and LM2576HVT-5.0/NOPB?

A: Both parts are electrically and mechanically identical. The "/NOPB" suffix indicates "No Plumbum" (lead-free) processing. LM2576HVT-5.0/NOPB is the active production part with manufacturer recommendation and higher inventory availability.

Q: Is LM2576T-005G compatible with input voltages below 7V?

A: No. LM2576T-005G specifies a minimum input voltage of 7V, compared to 4V for other 3A-rated substitutes. Applications requiring operation at input voltages between 4V and 7V must use LM2576HVT-5.0, LM2576HVT-5.0/NOPB, LM2576HVT-5.0/LF02, or LM2576-5.0WT.

Q: Can I use LM2576-5.0WT (Microchip) instead of LM2576HVT-5.0 (Texas Instruments)?

A: Yes, for applications with input voltages up to 40V. LM2576-5.0WT maintains identical 3A output current, 5V output voltage, 52kHz switching frequency, and TO-220-5 packaging. The maximum input voltage is limited to 40V compared to 60V for the original part. Verify your application's input voltage range before substitution.

Q: What does "Last Time Buy" status mean for LM2576HVT-5.0?

A: Last Time Buy indicates that Texas Instruments has discontinued production of this specific part number. Existing inventory may be available, but no new production runs are planned. Designers should transition to active alternatives such as LM2576HVT-5.0/NOPB or equivalent parts from alternative manufacturers to ensure long-term supply availability.

Q: Are all substitute parts available in the same TO-220-5 package?

A: Yes. All listed substitute parts use TO-220-5 through-hole packaging. LM2576HVT-5.0/LF02 specifies "TO-220-5 Formed Leads," indicating pre-formed leads for automated insertion, but the package footprint remains compatible with standard TO-220-5 PCB layouts.
