LM3526M-L Equivalent & Substitute Parts

Part Overview

The LM3526M-L is a Power Management IC (PMIC) functioning as a USB Switch/Driver with 1:2 P-Channel output configuration. This component is classified as Obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement. The LM3526M-L operates as a high-side P-channel power switch with dual outputs, delivering up to 500mA per channel with integrated current limiting, over-temperature protection, and under-voltage lockout (UVLO) fault protection.

Substitute Part Grouping Explanation

Substitution of the LM3526M-L is determined by strict equivalence across the following critical parameters: Switch Type (USB Switch), Number of Outputs (2), Input:Output Ratio (1:2), Output Configuration (High Side), Output Type (P-Channel), Load Voltage Range (2.7V ~ 5.5V), Maximum Output Current (500mA), On-Resistance (100mOhm typical), Input Type (Non-Inverting), Interface (On/Off), Fault Protection features (Current Limiting, Over Temperature, UVLO), Operating Temperature Range (-40°C ~ 125°C), and Package Type (8-SOIC).

The substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalent: LM3526M-L/NOPB maintains identical electrical and mechanical specifications with Active product status and Tube packaging.

Manufacturer Recommended Equivalent: LM3526MX-L/NOPB is the manufacturer-designated successor, offering identical functional parameters with Active status and Cut Tape (CT) & Digi-Reel® packaging.

Parametric Equivalent: LM3526M-H and LM3526M-H/NOPB share all electrical and mechanical parameters with the main part, differing only in product status (Obsolete and Active, respectively) and packaging format (Tube).

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, LM3526M-H/NOPB is the primary selection due to its Active product status, ROHS3 compliance, and identical electrical specifications. This part ensures long-term availability and supply chain continuity.

LM3526MX-L/NOPB serves as the manufacturer-recommended alternative, offering Active status with Cut Tape and Digi-Reel® packaging options suitable for high-volume automated assembly operations.

LM3526M-L/NOPB provides a direct equivalent with Active status and Tube packaging, suitable for applications where the original part number format is required.

The Obsolete-status parts (LM3526M-L and LM3526M-H) should be replaced in active designs. Existing inventory of these parts may be utilized for legacy system maintenance only.

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can LM3526M-H/NOPB be used as a direct replacement for LM3526M-L?

A: Yes. Both parts share identical electrical and mechanical specifications, including switch type, output configuration, voltage range, current rating, on-resistance, protection features, and operating temperature range. The primary difference is product status (Active vs. Obsolete) and packaging format (Tube). Pin-to-pin compatibility and functional equivalence are complete.

Q: What is the difference between LM3526M-L/NOPB and LM3526MX-L/NOPB?

A: Both parts are electrically and mechanically identical. The primary distinction is packaging format: LM3526M-L/NOPB uses Tube packaging, while LM3526MX-L/NOPB uses Cut Tape (CT) & Digi-Reel® packaging. The MX variant is the manufacturer-recommended successor for new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (LM3526M-L/NOPB, LM3526MX-L/NOPB, LM3526M-H, and LM3526M-H/NOPB) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new product designs?

A: LM3526M-H/NOPB or LM3526MX-L/NOPB are recommended for new designs due to Active product status. LM3526MX-L/NOPB is the manufacturer-designated successor and is preferred for high-volume production with automated assembly.

Q: Is the 8-SOIC package identical across all substitute parts?

A: Yes. All parts use the 8-SOIC package with 0.154" width (3.90mm). Pin configuration, footprint, and mechanical dimensions are identical, enabling direct PCB layout compatibility.

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

A: The /NOPB suffix indicates "No Plumbum" (lead-free) packaging, confirming ROHS3 compliance. Parts with this designation are suitable for applications requiring lead-free component specifications.
