LM2575TV-005G Equivalent & Substitute Parts

Part Overview

The LM2575TV-005G is a buck switching regulator IC manufactured by onsemi, designed for positive fixed 5V output at 1A in a TO-220-5 through-hole package. This device functions as a step-down converter with a fixed output topology and 52kHz switching frequency, suitable for applications requiring regulated 5V power from higher input voltage sources.

The LM2575TV-005G is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM2575TV-005G are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution validity:

Critical Matching Parameters:

• Output voltage: 5V fixed
• Output current capability: 1A minimum
• Package type: TO-220-5 Formed Leads
• Mounting type: Through Hole
• Switching frequency: 52kHz
• Function: Step-Down (Buck) topology
• Operating temperature range: -40°C to 125°C minimum

Allowable Parameter Variations:

• Input voltage range may exceed the original specification (higher maximum input voltage is acceptable)
• Manufacturer may differ
• Product status may be Active (preferred over Obsolete)
• RoHS compliance status may differ

The substitute parts identified below meet all critical matching parameters and represent direct functional equivalents suitable for replacement in applications originally designed for the LM2575TV-005G.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Texas Instruments and carry Active product status, providing superior supply chain availability compared to the obsolete onsemi LM2575TV-005G.

LM2575HVT-5.0/LF03 (Texas Instruments): This part maintains the same input voltage minimum (4V) as the original specification while extending the maximum input voltage to 60V. It is ROHS3 compliant and supplied in Tube packaging. This option is suitable for applications requiring extended input voltage range capability.

TL2575HV-05IKV (Texas Instruments): This part matches the original input voltage minimum of 4.75V and extends the maximum input voltage to 60V. It is ROHS3 compliant and supplied in Tube packaging. This option provides the closest electrical alignment to the original LM2575TV-005G specification.

Both substitute parts are electrically and mechanically compatible with the original design. Selection between them should be based on specific input voltage requirements of the application. Both are REACH compliant and classified under the same ECCN and HTSUS codes as the original part.

Frequently Asked Questions (FAQ)

Q: Can LM2575HVT-5.0/LF03 or TL2575HV-05IKV be used as direct replacements for LM2575TV-005G?

A: Yes. Both parts are direct functional equivalents. They provide identical output voltage (5V), output current (1A), switching frequency (52kHz), package type (TO-220-5 Formed Leads), and operating temperature range (-40°C to 125°C). No circuit modifications are required.

Q: What is the difference between the two substitute parts?

A: The primary difference is the input voltage minimum specification. LM2575HVT-5.0/LF03 accepts input voltages as low as 4V, while TL2575HV-05IKV requires a minimum of 4.75V. Both extend the maximum input voltage to 60V compared to the original 40V specification. Both are Active products from Texas Instruments with ROHS3 compliance.

Q: Are there any package or mounting differences?

A: No. All three parts use identical TO-220-5 Formed Leads packaging and through-hole mounting. PCB layout and thermal management considerations remain unchanged.

Q: What is the significance of the obsolete status of the original part?

A: The obsolete status of LM2575TV-005G indicates that onsemi has discontinued production and support. Using an Active substitute part from Texas Instruments ensures ongoing availability, technical support, and compliance with current manufacturing standards.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both LM2575HVT-5.0/LF03 and TL2575HV-05IKV are ROHS3 compliant. The original LM2575TV-005G RoHS status was not specified in the available data.

Q: Can I use these substitutes in new designs?

A: Yes. Both substitute parts are Active products suitable for new designs. They provide the same functional performance as the original part with extended input voltage range capability and current compliance certifications.
