Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP3852ET-2.5 is determined by strict equivalence across the following critical parameters:

• Output voltage: Fixed 2.5V
• Maximum output current: 1.5A minimum
• Maximum input voltage: 7V or greater
• Package type: TO-220-5 Formed Leads
• Mounting configuration: Through Hole
• Protection features: Over-current, over-temperature, and short-circuit protection
• Operating temperature range: -40°C to 125°C minimum

The LP3852ET-2.5/NOPB qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The LP3852ET-2.5/NOPB is the direct active equivalent for the obsolete LP3852ET-2.5. Both parts share identical electrical performance specifications and mechanical packaging. The LP3852ET-2.5/NOPB offers the advantage of active product status, ensuring continued availability and supply chain reliability.

For new designs or production transitions, the LP3852ET-2.5/NOPB is the appropriate selection. This part carries ROHS3 compliance certification, meeting current environmental and regulatory requirements, whereas the original part does not. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can LP3852ET-2.5/NOPB be used as a direct replacement for LP3852ET-2.5?

A: Yes. Both parts are electrically and mechanically identical. The LP3852ET-2.5/NOPB is the active production equivalent with improved compliance status.

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

A: The "/NOPB" designation indicates the part is supplied without plumbum (lead-free), reflecting RoHS3 compliance. This is a packaging and compliance designation, not a functional difference.

Q: Are there any performance differences between these parts?

A: No. Output voltage, current rating, dropout voltage, quiescent current, PSRR, protection features, and operating temperature range are identical across both part numbers.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active status ensures ongoing manufacturing, quality control, and supply availability. Obsolete parts may have limited stock and no guaranteed future availability.

Q: Does the packaging type difference (unspecified vs. Tube) affect compatibility?

A: No. Packaging type refers to the quantity container for shipment and storage. The component itself and its TO-220-5 package remain unchanged. Tube packaging is standard for active production parts.

Q: Are both parts suitable for -40°C to 125°C operating environments?

A: Yes. Both parts maintain identical operating temperature specifications across this full range.
