Substitute Part Grouping Explanation

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

• Electrical Performance: Output current rating (6A), on-resistance (18mOhm typical), voltage ratings (Load: 0.5V ~ 14.6V; Supply: 3V ~ 5.5V)
• Functional Architecture: 1:1 ratio, high-side N-channel configuration, non-inverting input, on/off interface
• Physical Form Factor: 8-DFN (2x2) package with exposed pad
• Environmental & Compliance: Operating temperature range (-40°C ~ 85°C), RoHS3 compliance, REACH unaffected status, MSL 3 rating

The NCP45525IMNTWG-H qualifies as a parametric equivalent substitute, maintaining identical electrical specifications and package configuration while offering improved product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The NCP45525IMNTWG-H is the direct parametric equivalent for the obsolete NCP45525IMNTWG-L. Both parts maintain identical electrical specifications, thermal characteristics, and package geometry. The substitute offers improved product lifecycle status (Last Time Buy versus Obsolete) and expanded packaging availability (Digi-Reel® option in addition to Cut Tape).

Selection between these parts should be based on supply chain availability and procurement timeline. The NCP45525IMNTWG-H provides extended design support window and broader sourcing options. Both parts satisfy identical compliance requirements (RoHS3, REACH unaffected) and environmental specifications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are parametrically equivalent across all electrical, thermal, and mechanical specifications. Pin configuration, package footprint, and functional behavior are identical. No circuit modifications are required.

Q: Are there differences in packaging between these parts?

A: Both parts use the 8-DFN (2x2) package with exposed pad. The NCP45525IMNTWG-H offers additional Digi-Reel® packaging option alongside standard Cut Tape, while the NCP45525IMNTWG-L is available in Cut Tape only.

Q: What is the significance of the product status difference?

A: NCP45525IMNTWG-L is classified as Obsolete, indicating end-of-life status. NCP45525IMNTWG-H is Last Time Buy, providing a defined window for procurement before discontinuation. For new designs or production continuity, the NCP45525IMNTWG-H is the preferred selection.

Q: Do these parts have identical thermal and compliance characteristics?

A: Yes. Both parts operate across -40°C to 85°C, maintain RoHS3 compliance, REACH unaffected status, and MSL 3 rating (168 hours). Thermal performance and environmental specifications are identical.

Q: What are the key electrical parameters that define substitutability?

A: Critical parameters include 6A maximum output current, 18mOhm typical on-resistance, 0.5V to 14.6V load voltage range, 3V to 5.5V supply voltage range, high-side N-channel configuration, and 1:1 input-output ratio. All parameters are matched between the main part and substitute.
