Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM2852YMXAX-1.0 is determined by strict equivalence across the following electrical and mechanical parameters:

• Fixed output voltage of 1V
• Output current rating of 2A
• Input voltage range of 2.85V to 5.5V
• Switching frequency of 500kHz
• Synchronous rectifier topology
• 14-PowerTSSOP package configuration
• Operating temperature range of -40°C to 125°C

The substitute part LM2852YMXAX-1.0/NOPB meets all these criteria. The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete), with improved RoHS3 compliance in the substitute variant.

Parameter Comparison

Engineering Selection Recommendations

The LM2852YMXAX-1.0/NOPB is the direct functional equivalent and recommended substitute for the obsolete LM2852YMXAX-1.0. Both parts share identical electrical specifications and package configuration. The substitute part offers the advantage of Active product status, ensuring continued manufacturer support and availability. Additionally, the LM2852YMXAX-1.0/NOPB meets RoHS3 compliance requirements, whereas the original part does not. For new designs or ongoing production requiring regulatory compliance, the substitute part is the appropriate selection. The Tape & Reel packaging format of the substitute is standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can LM2852YMXAX-1.0/NOPB be used as a direct replacement for LM2852YMXAX-1.0?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including output voltage, current rating, input voltage range, switching frequency, and package configuration. The substitute part is the active production variant.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (Active versus Obsolete) and RoHS compliance (RoHS3 Compliant versus non-compliant). The "/NOPB" suffix indicates Tape & Reel packaging format, standard for high-volume manufacturing.

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

A: No. Both parts operate across the same temperature range (-40°C to 125°C) and maintain identical switching frequency, output current capacity, and synchronous rectifier functionality.

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 dimensions, ensuring PCB layout compatibility.

Q: Which part should be specified for new designs?

A: The LM2852YMXAX-1.0/NOPB should be specified for new designs due to its Active status, RoHS3 compliance, and continued manufacturer support.
