LM3525MX-L Equivalent & Substitute Parts

Part Overview

The LM3525MX-L is a Power Management Integrated Circuit (PMIC) functioning as a P-Channel power switch driver with 1:1 input-to-output ratio and 500mA maximum output current. This component is classified as a USB Switch and operates in the 2.7V to 5.5V load voltage range with high-side output configuration.

The LM3525MX-L carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this power switch topology.

Parameter Comparison

Engineering Selection Recommendations

LM3525MX-H/NOPB and LM3525MX-L/NOPB are direct parametric equivalents to the LM3525MX-L. Both substitute parts are classified as Active products, providing superior supply chain availability compared to the Obsolete status of the original part.

Both substitute parts carry ROHS3 Compliance certification, whereas the LM3525MX-L is RoHS non-compliant. This compliance status difference is significant for applications subject to regulatory requirements or customer specifications mandating RoHS adherence.

The packaging designation difference (NOPB suffix indicating "No Plumbum" or lead-free) reflects the RoHS3 compliance of the substitute parts. The electrical and mechanical performance characteristics remain identical across all three part numbers.

Selection between LM3525MX-H/NOPB and LM3525MX-L/NOPB should be based on inventory availability and packaging format requirements (Cut Tape & Digi-Reel® for both substitutes versus Tape & Reel for the original part).

Frequently Asked Questions (FAQ)

Q: Can LM3525MX-H/NOPB or LM3525MX-L/NOPB be used as direct replacements for LM3525MX-L?

A: Yes. Both substitute parts maintain identical electrical specifications including output type (P-Channel), current rating (500mA), on-resistance (80mOhm), voltage range (2.7V ~ 5.5V), and fault protection features. Mechanical compatibility is confirmed through identical 8-SOIC packaging. The primary differences are product status (Active versus Obsolete) and RoHS compliance certification.

Q: What is the significance of the NOPB suffix on the substitute part numbers?

A: The NOPB suffix designates "No Plumbum" (lead-free) construction, indicating compliance with RoHS3 regulations. This reflects the manufacturing process used for the Active substitute parts, whereas the original LM3525MX-L is RoHS non-compliant.

Q: Are there packaging format differences between the original and substitute parts?

A: Yes. The LM3525MX-L is supplied in Tape & Reel (TR) format. Both substitute parts (LM3525MX-H/NOPB and LM3525MX-L/NOPB) are supplied in Cut Tape (CT) & Digi-Reel® format. The physical component dimensions and pinout remain identical; only the packaging and delivery format differ.

Q: Do the substitute parts support the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -40°C to 85°C (TA), ensuring thermal performance equivalence in target applications.

Q: What are the key electrical parameters that define substitutability for this USB power switch?

A: Substitutability is determined by: P-Channel output type, 1:1 input-to-output ratio, high-side output configuration, 500mA maximum output current, 80mOhm typical on-resistance, 2.7V to 5.5V load voltage range, non-inverting input type, on/off interface, status flag feature, and current limiting/over temperature/UVLO fault protection. All three parts match these specifications exactly.

Q: Is the Moisture Sensitivity Level (MSL) rating identical across all parts?

A: Yes. All three parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
