Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2575HVT-5.0/ELLI859 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Output voltage: 5V fixed
• Output current: 1A
• Input voltage range: 4V to 60V minimum
• Switching frequency: 52kHz
• Topology: Buck (step-down)
• Output configuration: Positive
• Synchronous rectifier capability: Not required

Mechanical & Environmental Specifications:

• Package type: TO-220-5
• Mounting method: Through hole
• Operating temperature range: -40°C to 125°C (TJ)
• Moisture sensitivity: MSL 1 or better

Compliance & Regulatory:

• RoHS3 compliance required
• ECCN: EAR99
• HTSUS: 8542.39.0001

Substitute parts must match all electrical parameters exactly and maintain compatibility with the TO-220-5 through-hole footprint. Packaging format (tube, tray, or reel) does not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

The LM2575HVT-5.0/NOPB is the direct equivalent substitute for the LM2575HVT-5.0/ELLI859. Both parts share identical electrical specifications, thermal characteristics, and mechanical packaging. The primary distinction is product lifecycle status: the ELLI859 variant is designated Last Time Buy, while the NOPB variant maintains Active status with higher inventory availability (4625 units versus 786 units).

From a compliance perspective, both parts satisfy ROHS3 requirements and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001). The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either variant.

Selection of the LM2575HVT-5.0/NOPB is appropriate for new designs and ongoing production requiring supply continuity. The Tube packaging format of the NOPB variant does not affect electrical or mechanical compatibility with applications designed for the ELLI859.

Frequently Asked Questions (FAQ)

Q: Can the LM2575HVT-5.0/NOPB be used as a direct replacement for the LM2575HVT-5.0/ELLI859?

A: Yes. Both parts are electrically and mechanically identical. They share the same output voltage (5V), output current (1A), input voltage range (4V to 60V), switching frequency (52kHz), TO-220-5 package, and operating temperature range (-40°C to 125°C). No circuit modifications are required.

Q: What is the difference between the ELLI859 and NOPB part numbers?

A: The ELLI859 and NOPB designations represent different packaging or distribution variants of the same base product (LM2575HVT-5.0). The ELLI859 is Last Time Buy status, while NOPB is Active status with higher inventory availability. Electrical and mechanical specifications are identical.

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

A: No. Both variants operate at the same switching frequency (52kHz), support the same output current (1A), and maintain identical thermal specifications across the -40°C to 125°C operating range.

Q: Does the packaging format (Tube versus unspecified) affect compatibility?

A: No. Packaging format affects only handling, storage, and supply chain logistics. Electrical and mechanical compatibility with the TO-220-5 footprint remains unchanged regardless of packaging format.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LM2575HVT-5.0/ELLI859 and LM2575HVT-5.0/NOPB carry ROHS3 Compliant status and are suitable for applications with RoHS compliance requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling and storage procedures apply without special moisture control requirements.
