LM2575T-015 Equivalent & Substitute Parts

Part Overview

The LM2575T-015 is a buck switching regulator IC manufactured by onsemi, designed for step-down voltage conversion applications. It delivers a fixed 15V output at 1A from input voltages ranging from 4.75V to 40V, operating at a switching frequency of 52kHz. The device is packaged in TO-220-5 through-hole configuration and is rated for operating temperatures from -40°C to 125°C.

This part is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and support long-term product availability for applications currently using this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM2575T-015 is determined by strict equivalence across the following critical parameters:

• Output voltage: 15V fixed
• Output current capability: 1A
• Input voltage range: 4.75V to 40V minimum
• Topology: Buck (step-down)
• Package: TO-220-5 through-hole
• Switching frequency: 52kHz
• Operating temperature range: -40°C to 125°C

The LM2575T-15G qualifies as a direct substitute based on identical electrical specifications and package configuration. Both parts share the same base product number (LM2575) and deliver equivalent functional performance for step-down regulation applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LM2575T-015 and LM2575T-15G are obsolete products. Selection between these parts should be based on compliance and certification status:

The LM2575T-015 carries RoHS non-compliant status, while the LM2575T-15G is ROHS3 compliant. For applications subject to RoHS regulations or requiring compliance documentation, the LM2575T-15G is the appropriate selection. Both parts maintain REACH Unaffected status and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Packaging differs between the two parts: LM2575T-015 is supplied without specified packaging, while LM2575T-15G is supplied in tube packaging. This distinction may affect handling, storage, and integration into automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are LM2575T-015 and LM2575T-15G electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance: 15V fixed output, 1A output current, 4.75V to 40V input range, 52kHz switching frequency, and -40°C to 125°C operating temperature range. They share the same base product number and topology.

Q: What is the primary difference between these two parts?

A: The LM2575T-15G is ROHS3 compliant, while the LM2575T-015 is RoHS non-compliant. Additionally, packaging differs: LM2575T-15G is supplied in tube format. Both parts are obsolete.

Q: Can I use LM2575T-15G as a direct replacement for LM2575T-015 in existing designs?

A: Yes, from an electrical and mechanical standpoint. The TO-220-5 package is identical, pin configuration is unchanged, and electrical specifications are equivalent. Compliance status should be verified against your application requirements.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate at identical switching frequency (52kHz), support the same output current (1A), and are rated for the same junction temperature range (-40°C to 125°C).

Q: What does "obsolete" status mean for these parts?

A: Both parts are classified as obsolete by the manufacturer. This indicates they are no longer in active production. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed.
