Substitute Part Grouping Explanation

Substitution of the LM2575T-005 is determined by the following critical parameters:

• Output Voltage: Fixed 5V output
• Output Current: 1A continuous output capability
• Input Voltage Range: 4.75V to 40V
• Topology: Buck (step-down) switching regulator
• Package Type: TO-220-5 through-hole mounting
• Base Product Series: LM2575

The LM2575T-5G qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while maintaining the same base product number (LM2575) and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The LM2575T-5G is the appropriate substitute for the obsolete LM2575T-005. Both components share identical electrical specifications for output voltage (5V), output current (1A), and input voltage operating range (4.75V to 40V). The LM2575T-5G maintains the same TO-220-5 package configuration, ensuring mechanical and thermal compatibility in existing PCB layouts.

The LM2575T-5G holds active product status with onsemi, providing ongoing availability and manufacturing support. The substitute part achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and production. Both components are classified as REACH Unaffected, maintaining consistency in regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the LM2575T-5G be used as a direct replacement for the LM2575T-005 in existing designs?

A: Yes. Both parts deliver identical electrical performance: 5V fixed output, 1A output current, and 4.75V to 40V input voltage range. The TO-220-5 package configuration is identical, allowing direct PCB substitution without layout modifications.

Q: What is the primary reason for substituting the LM2575T-005?

A: The LM2575T-005 is classified as obsolete. The LM2575T-5G is the active equivalent from the same manufacturer, ensuring continued component availability and manufacturing support.

Q: Are there compliance differences between these parts?

A: Yes. The LM2575T-005 is RoHS non-compliant, while the LM2575T-5G achieves ROHS3 compliance. For new designs subject to environmental regulations, the LM2575T-5G is the required choice. Both parts maintain REACH Unaffected status.

Q: Do the parts have identical thermal and frequency characteristics?

A: The LM2575T-5G operates across -40°C to 125°C junction temperature with a 52kHz switching frequency. The LM2575T-005 does not provide these specifications in the available documentation. The LM2575T-5G specifications represent the standard performance for the LM2575 base product series.

Q: Is the packaging identical between these parts?

A: Yes. Both the LM2575T-005 and LM2575T-5G use TO-220-5 through-hole packaging. No PCB layout or mechanical modifications are required for substitution.
