NCP45524IMNTWG-L Equivalent & Substitute Parts

Part Overview

The NCP45524IMNTWG-L is a Power Switch/Driver IC from onsemi's ecoSWITCH™ series, designed for high-side N-channel switching applications. This component operates as a 1:1 power switch with 6A output capability and is housed in an 8-DFN (2x2) surface mount package. The part is designated as Last Time Buy, indicating limited future availability. Identifying equivalent and substitute parts is essential for design continuity, inventory management, and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NCP45524IMNTWG-L is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Output current rating (6A), on-resistance (18mOhm typical), supply voltage range (3V ~ 5.5V), and load voltage range (0.5V ~ 14.6V)
• Functional Architecture: 1:1 input-to-output ratio, high-side N-channel configuration, non-inverting interface, and Power Good feature
• Package Compatibility: 8-VFDFN with exposed pad, surface mount technology
• Environmental & Compliance: Operating temperature range (-40°C ~ 85°C), ROHS3 compliance, MSL 3 rating

The substitute part NCP45524IMNTWG-H meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

The NCP45524IMNTWG-H is a direct parametric equivalent to the NCP45524IMNTWG-L. Both parts share identical electrical specifications, functional architecture, package geometry, and compliance certifications. The only distinction is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) and Digi-Reel® format.

Selection between these parts should be based on packaging requirements and inventory availability. Both parts carry Last Time Buy status from onsemi, indicating that long-term availability is limited for the entire NCP45524 product line. Current inventory levels show 16,081 units for the NCP45524IMNTWG-L and 8,571 units for the NCP45524IMNTWG-H.

Frequently Asked Questions (FAQ)

Q: Are NCP45524IMNTWG-L and NCP45524IMNTWG-H electrically interchangeable?

A: Yes. Both parts are parametrically identical across all electrical specifications, including output current (6A), on-resistance (18mOhm), supply voltage range (3V ~ 5.5V), and load voltage range (0.5V ~ 14.6V). They are direct substitutes for circuit design purposes.

Q: What is the difference between these two part numbers?

A: The difference is packaging format only. NCP45524IMNTWG-L is supplied in Tape & Reel (TR) format, while NCP45524IMNTWG-H is supplied in Cut Tape (CT) and Digi-Reel® format. The physical component, pin configuration, and performance characteristics are identical.

Q: Can I use NCP45524IMNTWG-H as a drop-in replacement for NCP45524IMNTWG-L on a PCB?

A: Yes. Both parts use the same 8-VFDFN package with exposed pad and identical pin assignments. No PCB layout modifications are required.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry MSL 3 rating (168 Hours), and meet identical environmental and regulatory requirements.

Q: Why is the main part designated as Last Time Buy?

A: Last Time Buy status indicates that onsemi has announced end-of-life for the NCP45524 product line. This affects both the NCP45524IMNTWG-L and NCP45524IMNTWG-H. Future availability is limited, and procurement planning should account for this status.

Q: Which packaging format should I select?

A: Selection depends on your procurement and assembly processes. Tape & Reel (TR) format is standard for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® formats are suitable for lower-volume or mixed-component orders. Electrical and mechanical performance is identical regardless of packaging format.
