LM3525MX-H Equivalent & Substitute Parts

Part Overview

The LM3525MX-H is a Power Management Integrated Circuit (PMIC) functioning as a P-Channel power switch driver with 1:1 input-to-output ratio, designed for USB switching applications. This component operates as a high-side switch with on/off interface control, delivering up to 500mA output current across a 2.7V to 5.5V load voltage range.

The LM3525MX-H carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production builds and system maintenance.

Parameter Comparison

Engineering Selection Recommendations

Both LM3525MX-H/NOPB and LM3525MX-L/NOPB are direct functional equivalents to the obsolete LM3525MX-H, with identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The LM3525MX-H carries Obsolete status, while both substitute parts maintain Active product status, ensuring long-term availability and continued manufacturer support.

Compliance Advantage: Both substitute parts achieve ROHS3 compliance, whereas the original LM3525MX-H is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic component procurement.

Packaging Availability: Both substitute parts are available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual assembly and automated production workflows.

Frequently Asked Questions (FAQ)

Q: Can LM3525MX-H/NOPB and LM3525MX-L/NOPB be used interchangeably with LM3525MX-H?

A: Yes. Both parts maintain identical electrical specifications including switch type, output configuration, voltage ratings, current capacity, on-resistance, protection features, and operating temperature range. The 8-SOIC package dimensions are identical, enabling direct PCB footprint compatibility.

Q: What is the difference between LM3525MX-H/NOPB and LM3525MX-L/NOPB?

A: Both parts are parametrically equivalent across all electrical and mechanical specifications provided. The designation difference reflects internal Texas Instruments product line management but does not affect functional performance or circuit compatibility.

Q: Why is the original LM3525MX-H marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. The substitute parts LM3525MX-H/NOPB and LM3525MX-L/NOPB maintain Active status, ensuring continued availability and manufacturer technical support.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The original LM3525MX-H is RoHS non-compliant, while both substitute parts (LM3525MX-H/NOPB and LM3525MX-L/NOPB) are ROHS3 compliant. This compliance improvement is beneficial for applications subject to RoHS regulatory requirements.

Q: What packaging formats are available for the substitute parts?

A: Both LM3525MX-H/NOPB and LM3525MX-L/NOPB are supplied in Cut Tape (CT) and Digi-Reel® packaging, supporting both manual and automated assembly processes.

Q: Are the pin configurations identical across all three parts?

A: Yes. All three parts use the 8-SOIC package with identical pin assignments, enabling direct replacement without circuit board redesign or pin remapping.
