Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM2852XMXAX-2.5 is determined by strict equivalence across the following electrical and mechanical parameters:

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

The LM2852XMXAX-2.5/NOPB qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between the main part and its substitute is product status and packaging format, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LM2852XMXAX-2.5/NOPB is the direct active equivalent for the obsolete LM2852XMXAX-2.5. Selection of the substitute part is based on the following engineering criteria:

• The substitute maintains identical electrical specifications and package footprint, ensuring direct PCB compatibility without design modification.
• The substitute carries active product status, ensuring long-term availability and continued manufacturer support.
• The substitute achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new production and procurement.
• The substitute is supplied in Tape & Reel format, which is the standard packaging for high-volume manufacturing and automated assembly processes.

For applications currently using the obsolete LM2852XMXAX-2.5, transition to the LM2852XMXAX-2.5/NOPB requires no circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the LM2852XMXAX-2.5/NOPB be used as a direct replacement for the LM2852XMXAX-2.5?

A: Yes. Both parts are electrically and mechanically identical. The substitute features identical output voltage (2.5V), output current (2A), input voltage range (2.85V to 5.5V), switching frequency (1.5MHz), and 14-PowerTSSOP package configuration. No circuit or PCB modifications are required.

Q: What is the difference between the main part and the substitute?

A: The primary differences are product status and packaging format. The LM2852XMXAX-2.5 is obsolete and supplied in tube packaging, while the LM2852XMXAX-2.5/NOPB is active and supplied in Tape & Reel format. Additionally, the substitute achieves ROHS3 compliance, whereas the main part is RoHS non-compliant.

Q: Why is the substitute supplied in Tape & Reel format?

A: Tape & Reel packaging is the standard format for surface-mount components in automated manufacturing environments. This format enables high-speed pick-and-place assembly and is the preferred packaging for production quantities.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical electrical specifications, including switching frequency (1.5MHz), synchronous rectification capability, operating temperature range (-40°C to 125°C), and all voltage and current parameters.

Q: Is the 14-PowerTSSOP package footprint identical between both parts?

A: Yes. Both parts use the 14-PowerTSSOP package with 0.173" width and 4.40mm body width. PCB layouts designed for the main part require no modification for the substitute.
