Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM2852YMXA-1.5 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 1.5V
• Output current rating of 2A
• Input voltage operating range of 2.85V to 5.5V
• Buck topology with synchronous rectification
• 500kHz switching frequency
• 14-PowerTSSOP package configuration
• Operating temperature range of -40°C to 125°C

The LM2852YMXA-1.5/NOPB qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction between these parts is product status and packaging format, with the /NOPB variant currently in active production status and supplied in tube packaging, whereas the base part number is obsolete.

Engineering Selection Recommendations

The LM2852YMXA-1.5/NOPB is the appropriate selection for new designs and production continuity. This variant maintains complete electrical and mechanical equivalence to the obsolete LM2852YMXA-1.5 while offering the following advantages:

• Active product status ensures long-term availability and manufacturing support
• ROHS3 compliance satisfies current regulatory requirements for electronic components
• Tube packaging provides standard handling and storage compatibility with modern supply chain operations

For applications requiring the exact electrical performance and package footprint of the original LM2852YMXA-1.5, the /NOPB variant provides direct functional replacement without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the LM2852YMXA-1.5/NOPB be used as a direct replacement for the LM2852YMXA-1.5?

A: Yes. Both parts are electrically and mechanically identical. They share the same output voltage (1.5V), output current (2A), input voltage range (2.85V–5.5V), switching frequency (500kHz), and 14-PowerTSSOP package configuration. The /NOPB variant is the active production equivalent.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB designation indicates "No Lead (Pb)" and reflects RoHS3 compliance. This suffix distinguishes the active production variant from the obsolete base part number and confirms lead-free manufacturing.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the 14-PowerTSSOP package with identical pin configuration and footprint dimensions (0.173" width, 4.40mm). Existing PCB designs require no modification.

Q: What is the operating temperature range for both parts?

A: Both the LM2852YMXA-1.5 and LM2852YMXA-1.5/NOPB operate across -40°C to 125°C junction temperature, supporting industrial and extended temperature applications.

Q: Why is the original LM2852YMXA-1.5 marked as obsolete?

A: The base part number has been superseded by the /NOPB variant to align with RoHS3 compliance requirements and modern supply chain standards. The /NOPB version provides identical functionality with current regulatory certification.
