LM25115SDX Equivalent & Substitute Parts Engineering Reference

Part Overview

LM25115SDX is a Power Management Integrated Circuit (PMIC) designed as a secondary-side power supply controller, featuring a maximum input voltage of 42V and housed in a 16-WSON (5x5) surface-mount package. This part is obsolete; as such, identification of direct substitutes is necessary for continued production, maintenance, and inventory fulfillment. Substitute components with matching electrical and mechanical parameters ensure functional equivalence and compatible form factor in existing designs where the LM25115SDX is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by the direct equivalence of specified electrical parameters (Voltage - Input, Voltage - Supply, Current - Supply, Operating Temperature), mechanical parameters (Package / Case, Supplier Device Package, Mounting Type), and compliance (RoHS, REACH, MSL). Substitute parts must be within the same base product series (LM25115), possess identical package formats, and support identical operating ranges. Only direct matches to these allowed parameters are considered as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The LM25115SDX is obsolete with RoHS non-compliant status. LM25115SDX/NOPB maintains identical key electrical and mechanical parameters and is RoHS3 compliant, REACH unaffected, and actively available. For compliance-focused designs and ongoing availability requirements, LM25115SDX/NOPB qualifies as a direct substitute based solely on provided product status and certifications.

Frequently Asked Questions (FAQ)

Q1: What parameters are essential for identifying substitutes for LM25115SDX?
A1: Substitutes are based only on the same input voltage range, supply voltage, supply current, operating temperature, mounting type, package/case, supplier device package, and application.

Q2: Is LM25115SDX/NOPB compatible in footprint and electrical function with LM25115SDX?
A2: LM25115SDX/NOPB is a direct drop-in substitute with equivalent footprint (16-WSON (5x5)), identical input and supply voltages, current, and operating temperature.

Q3: Are there differences in environmental compliance between LM25115SDX and LM25115SDX/NOPB?
A3: LM25115SDX/NOPB is ROHS3 compliant and REACH unaffected. LM25115SDX is RoHS non-compliant.

Q4: Does the substitute maintain the same mounting and packaging requirements?
A4: Both LM25115SDX and LM25115SDX/NOPB support surface mount installation and 16-WFDFN Exposed Pad package.

Q5: Is the substitute appropriate for all secondary-side controller applications listed for the main part?
A5: LM25115SDX/NOPB is designated for identical applications per the provided information.
