Substitute Part Grouping Explanation

Substitution for the LM2852YMXA-2.5 is determined by the following critical parameters:

• Fixed output voltage of 2.5V
• Output current rating of 2A
• Input voltage range of 2.85V to 5.5V
• Buck topology with synchronous rectification
• 14-PowerTSSOP package footprint
• Operating temperature range of -40°C to 125°C

The LM2852YMXA-2.5/NOPB qualifies as a direct substitute based on identical electrical specifications, package type, and pinout compatibility. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The LM2852YMXA-2.5/NOPB is the direct substitute for the obsolete LM2852YMXA-2.5. Both parts share identical electrical specifications, pinout, and package footprint, ensuring drop-in compatibility at the circuit board level.

The LM2852YMXA-2.5/NOPB offers the following advantages for new designs and production continuity:

• Active product status with confirmed inventory availability
• ROHS3 compliance, meeting current environmental and regulatory requirements
• Tube packaging format suitable for automated assembly processes
• Identical performance characteristics across all specified operating parameters

For applications currently using the obsolete LM2852YMXA-2.5, migration to the LM2852YMXA-2.5/NOPB requires no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can the LM2852YMXA-2.5/NOPB be used as a direct replacement for the LM2852YMXA-2.5?

A: Yes. Both parts are electrically and mechanically identical. The LM2852YMXA-2.5/NOPB is a direct substitute with no circuit modifications required.

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

A: The "/NOPB" suffix indicates that the part is supplied without plumbum (lead-free). This designation reflects the RoHS3 compliance status of the substitute part.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 14-PowerTSSOP package with identical pinout and footprint dimensions (0.173", 4.40mm Width). PCB layouts are fully compatible.

Q: What is the significance of the product status difference?

A: The LM2852YMXA-2.5 is classified as obsolete, meaning it is no longer manufactured or supported by Texas Instruments. The LM2852YMXA-2.5/NOPB is active and available from authorized distributors, ensuring long-term supply chain reliability.

Q: Does the RoHS3 compliance of the substitute affect circuit performance?

A: No. RoHS3 compliance reflects manufacturing process changes related to material composition and environmental standards. Electrical performance and operating characteristics remain identical.

Q: What is the recommended approach for existing designs using the obsolete part?

A: For production continuity, transition to the LM2852YMXA-2.5/NOPB. No design changes, PCB modifications, or firmware updates are necessary. The substitute part is a direct replacement.
