NCP45525IMNTWG-H Equivalent & Substitute Parts

Part Overview

The NCP45525IMNTWG-H is a Power Switch/Driver IC manufactured by onsemi, designed as a 1:1 N-Channel high-side switch with 6A output capability in an 8-DFN (2x2) package. This component operates within a supply voltage range of 3V to 5.5V and supports load voltages from 0.5V to 14.6V, making it suitable for general-purpose switching applications requiring controlled slew rate operation.

The NCP45525IMNTWG-H currently holds Last Time Buy status, indicating that the manufacturer has announced end-of-life production. This status necessitates identification of equivalent substitute parts to ensure design continuity and long-term supply chain reliability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NCP45525IMNTWG-H is determined by strict equivalence across the following critical parameters:

• Output Configuration & Topology: High-side N-channel switch with 1:1 input-to-output ratio
• Electrical Performance: 6A maximum output current, 18mOhm typical on-resistance, 3V to 5.5V supply voltage range, 0.5V to 14.6V load voltage range
• Interface & Control: Non-inverting on/off control with slew rate control features
• Package Compatibility: 8-VFDFN exposed pad surface mount package (2x2mm footprint)
• Environmental & Compliance: Operating temperature range -40°C to 85°C, ROHS3 compliance, MSL 3 rating

The NCP45525IMNTWG-L meets all these criteria as a parametric equivalent within the ecoSWITCH™ series. The primary distinction between these parts is product status: the -H variant is Last Time Buy, while the -L variant is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The NCP45525IMNTWG-L serves as a direct parametric equivalent to the NCP45525IMNTWG-H. Both parts are ROHS3 compliant and carry identical electrical specifications, thermal operating ranges, and package configurations.

Selection between these parts should be based on supply chain availability and procurement timeline:

• NCP45525IMNTWG-H (Last Time Buy): Suitable for immediate procurement where inventory is available. This status indicates limited remaining production windows.
• NCP45525IMNTWG-L (Obsolete): Available only through existing inventory channels. Procurement of this variant should be evaluated based on current stock levels and long-term supply requirements.

Both parts maintain full compatibility with existing PCB layouts and circuit designs due to identical package footprints and electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can NCP45525IMNTWG-L be used as a direct replacement for NCP45525IMNTWG-H?

A: Yes. Both parts are parametrically equivalent across all electrical, thermal, and mechanical specifications. They share identical package footprints (8-VFDFN exposed pad), supply voltage ranges (3V to 5.5V), output current ratings (6A), and on-resistance characteristics (18mOhm typical). PCB layout and circuit design modifications are not required.

Q: What is the difference between the -H and -L suffix designations?

A: The suffix designates product lifecycle status. The -H variant is Last Time Buy, indicating the manufacturer has announced end-of-life production with a defined final order date. The -L variant is Obsolete, meaning production has ceased and the part is available only through existing inventory channels.

Q: Are there packaging differences between these parts?

A: No. Both parts utilize the 8-VFDFN exposed pad surface mount package with identical 2x2mm footprint dimensions. Cut Tape (CT) and Digi-Reel® packaging options are available for the -H variant, while the -L variant is available in Cut Tape (CT) packaging.

Q: Do these parts have identical moisture sensitivity ratings?

A: Yes. Both parts carry MSL 3 rating with 168-hour floor life, requiring identical handling and storage protocols during manufacturing and assembly operations.

Q: Are both parts ROHS3 compliant?

A: Yes. Both NCP45525IMNTWG-H and NCP45525IMNTWG-L are ROHS3 compliant and carry identical REACH Unaffected status.
