Substitute Part Grouping Explanation

Substitution for the LM2592HVT-5.0 is determined by the following critical parameters: fixed 5V output voltage, positive output configuration, buck topology, TO-220-5 package compatibility, through-hole mounting, and operating temperature range of -40°C to 125°C. Substitute parts must maintain these core electrical and mechanical specifications to ensure direct replacement capability.

The substitute parts are grouped into two categories based on output current capability:

Direct Equivalent (2A Output): LM2592HVT-5.0/NOPB maintains identical electrical specifications and output current rating, differing only in packaging format and RoHS compliance status.

Functional Alternatives (1A to 3A Output Range): LM2575-5.0WT, LM2575T-5G, and LM2576T-005G provide 5V fixed output in TO-220-5 packages with varying current ratings and input voltage ranges. These parts share the same topology, package, and temperature range but differ in output current capacity and input voltage specifications.

Engineering Selection Recommendations

LM2592HVT-5.0/NOPB is the primary direct equivalent for the LM2592HVT-5.0. Both parts are manufactured by Texas Instruments with identical electrical specifications, output current rating of 2A, and input voltage range of 4.5V to 60V. The LM2592HVT-5.0/NOPB is currently active in production and ROHS3 compliant, addressing the obsolescence status of the original part. This substitute is recommended for applications requiring exact electrical and thermal performance matching.

LM2575-5.0WT (Microchip Technology) and LM2575T-5G (onsemi) are functional alternatives suitable for applications where 1A output current is sufficient. Both parts maintain the 5V fixed output, TO-220-5 package, and -40°C to 125°C operating range. These parts operate at 52kHz switching frequency compared to the LM2592HVT-5.0's 150kHz, and have reduced maximum input voltage of 40V. Both are ROHS3 compliant and active in production.

LM2576T-005G (onsemi) provides 3A output current in the same TO-220-5 package, suitable for applications requiring higher current delivery than the original 2A specification. This part has a minimum input voltage requirement of 7V and maximum of 40V, with 52kHz switching frequency. It is ROHS3 compliant and active in production.

Frequently Asked Questions (FAQ)

Q: Can LM2592HVT-5.0/NOPB be used as a direct replacement for LM2592HVT-5.0?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, output current rating, input voltage range, and TO-220-5 package. The primary difference is that LM2592HVT-5.0/NOPB is active in production and ROHS3 compliant, while the original part is obsolete and RoHS non-compliant.

Q: What are the key differences between the LM2592HVT-5.0 and the LM2575 series substitutes?

A: The LM2592HVT-5.0 delivers 2A output current at 150kHz switching frequency with input voltage range of 4.5V to 60V. The LM2575-5.0WT and LM2575T-5G deliver 1A output current at 52kHz switching frequency with input voltage range of 4V to 40V (or 4.75V to 40V). Selection depends on required output current and input voltage specifications.

Q: Is the LM2576T-005G suitable for applications designed for the LM2592HVT-5.0?

A: The LM2576T-005G can be used in applications where the 2A output current requirement can be met with 3A capability. However, the minimum input voltage requirement of 7V must be verified against the original design specification of 4.5V minimum. The 52kHz switching frequency differs from the original 150kHz.

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

A: Yes. All substitute parts listed are packaged in TO-220-5 through-hole format, ensuring mechanical compatibility with the original LM2592HVT-5.0 footprint and mounting requirements.

Q: What is the compliance status of the substitute parts?

A: LM2592HVT-5.0/NOPB, LM2575-5.0WT, LM2575T-5G, and LM2576T-005G are all ROHS3 compliant and currently active in production, addressing the obsolescence and non-compliance status of the original LM2592HVT-5.0.
