LM2590HVT-5.0 Equivalent & Substitute Parts

Part Overview

The LM2590HVT-5.0 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 5V output and 1A output current capability. This device operates across a wide input voltage range of 4.5V to 60V and is housed in a TO-220-7 package with formed leads for through-hole mounting.

The LM2590HVT-5.0 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with active manufacturing support and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM2590HVT-5.0 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration (5V fixed)
• Output current rating (1A)
• Input voltage operating range (4.5V to 60V minimum)
• Switching topology (buck converter)
• Package and pinout compatibility (TO-220-7 Formed Leads)
• Thermal operating range (-40°C to 125°C)
• Switching frequency (150kHz)

The LM2590HVT-5.0/NOPB qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The LM2590HVT-5.0/NOPB is the direct equivalent for the obsolete LM2590HVT-5.0. Both devices share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

Selection between these parts should be based on the following factors:

• Product Status: The LM2590HVT-5.0/NOPB carries active product status with ongoing manufacturing support, whereas the LM2590HVT-5.0 is obsolete and subject to supply discontinuation.
• Compliance Requirements: The LM2590HVT-5.0/NOPB meets RoHS3 compliance standards. If regulatory compliance is a design requirement, the /NOPB variant is the appropriate selection.
• Supply Availability: The LM2590HVT-5.0/NOPB is available in active inventory with tube packaging, supporting production and procurement workflows.

For new designs or redesigns of existing products using the LM2590HVT-5.0, transition to the LM2590HVT-5.0/NOPB is the standard engineering practice.

Frequently Asked Questions (FAQ)

Q: Are the LM2590HVT-5.0 and LM2590HVT-5.0/NOPB pin-compatible?

A: Yes. Both devices use the TO-220-7 package with identical pinout and electrical characteristics. Direct substitution on the PCB is possible without circuit modification.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix designates "No Plumbum" (lead-free) packaging and RoHS3 compliance. This reflects the manufacturing process and environmental compliance certification of the component.

Q: Can the LM2590HVT-5.0/NOPB replace the LM2590HVT-5.0 in existing designs?

A: Yes. The electrical performance, thermal characteristics, and mechanical form factor are identical. The LM2590HVT-5.0/NOPB is a direct functional replacement suitable for both new production and field service applications.

Q: Why is the LM2590HVT-5.0 marked as obsolete?

A: Obsolescence reflects Texas Instruments' product lifecycle management. The LM2590HVT-5.0/NOPB represents the current active equivalent with ongoing support and compliance certifications.

Q: Are there differences in thermal performance between these parts?

A: No. Both devices operate across the same temperature range (-40°C to 125°C junction temperature) and share identical thermal characteristics.

Q: What packaging options are available?

A: The LM2590HVT-5.0 was supplied in bulk packaging. The LM2590HVT-5.0/NOPB is supplied in tube packaging, which is standard for active production components and supports automated assembly processes.
