Substitute Part Grouping Explanation

Substitution for the LM2852YMXA-1.3 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 1.3V
• 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 LM2852YMXA-1.3/NOPB represents a direct equivalent part from the same manufacturer and base product series (LM2852), maintaining identical electrical specifications and mechanical packaging. The primary distinction is product status: the original part is obsolete, while the substitute is active in production.

Parameter Comparison

Engineering Selection Recommendations

The LM2852YMXA-1.3/NOPB is the direct active equivalent for the obsolete LM2852YMXA-1.3. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The substitute part carries ROHS3 compliance status, whereas the original part is non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

For new designs or procurement requiring active component availability, the LM2852YMXA-1.3/NOPB is the appropriate selection. The "/NOPB" suffix indicates lead-free plating, consistent with modern manufacturing standards. Inventory availability shows 911 units in stock for the active equivalent compared to 1355 units for the obsolete variant.

Frequently Asked Questions (FAQ)

Q: Can the LM2852YMXA-1.3/NOPB be used as a direct replacement for the LM2852YMXA-1.3?

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

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

A: The "/NOPB" designation indicates lead-free plating on the component leads, reflecting compliance with modern environmental and manufacturing standards. This does not affect electrical performance or compatibility.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The original LM2852YMXA-1.3 is RoHS non-compliant, while the LM2852YMXA-1.3/NOPB is ROHS3 compliant. For applications requiring RoHS compliance certification, the substitute part is the appropriate choice.

Q: Does the packaging format difference (unspecified vs. Tube) affect compatibility?

A: No. Packaging format refers to the quantity and presentation method for procurement and handling. The component itself and its mounting characteristics remain unchanged. Both use 14-PowerTSSOP surface mount packages.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both parts are rated for -40°C to 125°C junction temperature operation, supporting identical thermal specifications.
