Substitute Part Grouping Explanation

Substitution for the LM2852YMXAX-1.2 is determined by strict equivalence across the following electrical and mechanical parameters:

• Fixed output voltage of 1.2V
• 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 LM2852YMXAX-1.2/NOPB qualifies as a direct substitute based on identical electrical specifications and package footprint. 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 LM2852YMXAX-1.2/NOPB is the direct equivalent substitute for the obsolete LM2852YMXAX-1.2. Both parts share identical electrical specifications and mechanical footprints, ensuring pin-for-pin compatibility and functional interchangeability in circuit designs.

Selection between these parts should be based on the following factors:

• Product Availability: The LM2852YMXAX-1.2/NOPB is currently active and maintains higher inventory levels (6650 pcs vs. 2324 pcs), making it the preferred choice for new designs and ongoing production.
• Regulatory Compliance: The LM2852YMXAX-1.2/NOPB meets ROHS3 compliance requirements, whereas the main part number is RoHS non-compliant. For applications subject to RoHS regulations, the substitute part is mandatory.
• Packaging Format: The LM2852YMXAX-1.2/NOPB is supplied in Tape & Reel format, suitable for automated assembly processes. The main part number may be available in alternative packaging formats for lower-volume applications.

Frequently Asked Questions (FAQ)
