Substitute Part Grouping Explanation

The LM2576TV-5G qualifies as a direct substitute for the LM2576TV-005 based on the following substitution criteria:

• Manufacturer Continuity: Both parts are manufactured by onsemi and share the same base product number (LM2576)
• Functional Equivalence: Both devices perform step-down (buck) switching regulation with identical output specifications (5V fixed, 3A output current)
• Electrical Parameters: Input voltage range (7V–40V), output voltage (5V), output current (3A), and switching frequency (52kHz) are identical
• Package Compatibility: Both use TO-220-5 Formed Leads packaging, ensuring mechanical and thermal compatibility
• Operating Temperature Range: Both operate across -40°C to 125°C (TJ)
• Regulatory Compliance: Both are classified as REACH Unaffected and ECCN EAR99

The primary distinction is product status: LM2576TV-005 is obsolete, while LM2576TV-5G is active and RoHS3 compliant.

Engineering Selection Recommendations

The LM2576TV-5G is the appropriate substitute for the obsolete LM2576TV-005. Selection is based on:

• Product Status Alignment: LM2576TV-5G is active and currently in production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: LM2576TV-5G achieves RoHS3 compliance, meeting modern environmental and material restriction requirements, whereas LM2576TV-005 is RoHS non-compliant
• Functional Equivalence: Identical electrical specifications (5V output, 3A current, 7V–40V input range) and package form factor ensure direct substitution without circuit redesign
• Certification Maintenance: Both parts maintain REACH Unaffected and EAR99 ECCN classifications, preserving regulatory standing

For applications requiring RoHS compliance or new procurement, LM2576TV-5G is the designated replacement.

Frequently Asked Questions (FAQ)

Q: Can LM2576TV-5G be used as a direct replacement for LM2576TV-005 in existing designs?

A: Yes. Both parts share identical output specifications (5V, 3A), input voltage range (7V–40V), and TO-220-5 package configuration. No circuit modifications are required for substitution.

Q: What is the primary reason to transition from LM2576TV-005 to LM2576TV-5G?

A: LM2576TV-005 is obsolete and no longer manufactured. LM2576TV-5G is the active equivalent from the same manufacturer (onsemi) and base product family (LM2576), ensuring continued availability and support.

Q: Are there compliance differences between these parts?

A: Yes. LM2576TV-5G is RoHS3 compliant, while LM2576TV-005 is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 ECCN classification.

Q: Is the package form factor identical?

A: Both parts use TO-220-5 packaging. LM2576TV-5G specifies "Formed Leads," which is a standard manufacturing detail for this package type and does not affect mechanical or thermal compatibility.

Q: Are there any electrical parameter differences?

A: No. Output voltage (5V), output current (3A), input voltage range (7V–40V), and switching frequency (52kHz) are identical between both parts.

Q: What is the switching frequency of these regulators?

A: The switching frequency is 52kHz for both the LM2576TV-005 and LM2576TV-5G.
