Key Parameters

Substitute Part Grouping Explanation

Substitution of the FPF2163 is determined by the following critical parameters:

• Output Type & Configuration: P-Channel, High Side, 1:1 ratio
• Current Rating: 1.5A maximum output current
• Load Voltage Range: Minimum 1.8V support required
• Fault Protection: Current limiting, over-temperature, reverse current, UVLO
• Package Compatibility: Surface mount, 6-pin configuration with exposed pad
• Compliance: ROHS3 compliant, MSL 1

The NCP380HMU15AATBG meets these core functional requirements while offering improved specifications and Active product status. Both parts share identical output current capacity, operating temperature range, and compliance certifications. The primary differences lie in load voltage minimum specification, on-resistance characteristics, and available fault protection features.

Parameter Comparison

Engineering Selection Recommendations

The NCP380HMU15AATBG is the direct functional equivalent for FPF2163 replacement. Selection criteria are based on the following factors:

Product Status: The FPF2163 is Obsolete, while NCP380HMU15AATBG maintains Active status, ensuring long-term availability and manufacturing support.

Compliance & Certifications: Both parts maintain identical ROHS3 compliance, MSL 1 rating, and REACH unaffected status, meeting regulatory requirements for equivalent applications.

Load Voltage Consideration: The NCP380HMU15AATBG specifies a minimum load voltage of 2.5V compared to FPF2163's 1.8V minimum. Applications requiring operation below 2.5V require design verification against the substitute part's datasheet.

Package Transition: Both parts use 6-pin exposed pad configurations (WDFN vs. UDFN). Physical footprint differences require PCB layout verification prior to implementation.

Performance Characteristics: The NCP380HMU15AATBG provides lower on-resistance (55mOhm vs. 120mOhm), resulting in reduced power dissipation and improved thermal performance in equivalent current applications.

Frequently Asked Questions (FAQ)

Q: Can NCP380HMU15AATBG directly replace FPF2163 in existing designs?

A: Functional replacement is possible when load voltage remains at or above 2.5V. The lower on-resistance of NCP380HMU15AATBG provides improved performance. PCB layout modifications may be required due to package differences (WDFN to UDFN transition).

Q: What are the key differences between FPF2163 and NCP380HMU15AATBG?

A: Primary differences include product status (Obsolete vs. Active), minimum load voltage specification (1.8V vs. 2.5V), on-resistance (120mOhm vs. 55mOhm), and package designation (WDFN vs. UDFN). Both maintain identical current rating, operating temperature range, and compliance certifications.

Q: Are there package compatibility concerns?

A: Both parts use 6-pin surface mount packages with exposed pads. WDFN and UDFN packages have different physical dimensions and pin layouts. Verify PCB footprint compatibility and thermal pad design before implementation.

Q: What fault protection features are available in the substitute part?

A: NCP380HMU15AATBG provides current limiting (fixed), UVLO, and enable input with slew rate control. FPF2163 includes adjustable current limiting, over-temperature protection, and reverse current blocking. Verify fault protection requirements against application specifications.

Q: Is the substitute part suitable for applications below 2.5V load voltage?

A: NCP380HMU15AATBG specifies minimum load voltage of 2.5V. Applications requiring operation at 1.8V to 2.4V require datasheet review and design validation before substitution.
