Substitute Part Grouping Explanation

Substitution for the LM2852YMXAX-1.5 is determined by strict equivalence across the following electrical and mechanical parameters:

• Fixed output voltage of 1.5V
• Output current rating of 2A
• Input voltage 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 LM2852YMXAX-1.5/NOPB qualifies as a direct substitute based on identical electrical specifications and package form factor. The primary distinction between the main part and its substitute is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The LM2852YMXAX-1.5/NOPB is the direct functional equivalent of the LM2852YMXAX-1.5. Selection between these parts should be based on the following criteria:

Product Status: The LM2852YMXAX-1.5 is classified as obsolete, while the LM2852YMXAX-1.5/NOPB maintains active status. For new designs or production continuity, the active part number is the appropriate choice.

Regulatory Compliance: The LM2852YMXAX-1.5/NOPB is ROHS3 compliant, whereas the original part is RoHS non-compliant. Applications subject to RoHS requirements must use the compliant variant.

Packaging Configuration: The LM2852YMXAX-1.5/NOPB is supplied in Tape & Reel format, suitable for automated assembly processes. The original part is supplied in bulk packaging. Packaging selection depends on production volume and assembly methodology.

Both parts share identical electrical performance, thermal characteristics, and package footprint, ensuring direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the LM2852YMXAX-1.5/NOPB replace the LM2852YMXAX-1.5 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The substitute part maintains the same output voltage (1.5V), output current (2A), input voltage range (2.85V to 5.5V), switching frequency (500kHz), and 14-PowerTSSOP package footprint. No circuit modifications are required.

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

A: The primary differences are product status and packaging. The LM2852YMXAX-1.5 is obsolete and supplied in bulk packaging. The LM2852YMXAX-1.5/NOPB is active, supplied in Tape & Reel format, and is ROHS3 compliant. The "/NOPB" suffix indicates lead-free (no-lead) construction.

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 deliver identical electrical performance. Thermal characteristics and switching behavior are equivalent.

Q: Which part should be used for new production?

A: The LM2852YMXAX-1.5/NOPB should be used for new designs and ongoing production. It is the active part number with current manufacturing support and regulatory compliance.

Q: Is the package footprint identical?

A: Yes. Both parts use the 14-PowerTSSOP package with 0.173" width and 4.40mm dimensions. PCB layouts and component placement are fully compatible.
