Key Parameters

Substitute Part Grouping Explanation

Substitute components for the FPF3003UCX are identified based on the following critical parameters that define functional equivalence:

• Type: Source Selector Switch
• FET Type: P-Channel
• Ratio - Input:Output: 2:1
• Internal Switch(s): Yes (integrated switching architecture)
• Current - Output (Max): Minimum 2.5A capability
• Voltage - Supply Range: Compatibility with 2.3V ~ 5.5V operation
• Applications: Handheld/Mobile Devices
• Mounting Type: Surface Mount

The LTC4413EDD#TRPBF from Analog Devices Inc. meets these core functional requirements. While package geometry differs (10-DFN versus 16-WLCSP), the electrical performance parameters and application suitability align with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The LTC4413EDD#TRPBF is the identified substitute for the obsolete FPF3003UCX based on functional equivalence in source selector switch architecture, P-Channel FET topology, and 2:1 input-to-output ratio.

Key considerations for selection:

• Product Status: The LTC4413EDD#TRPBF is actively manufactured by Analog Devices Inc., ensuring long-term availability and supply chain stability compared to the obsolete FPF3003UCX.

• Compliance: The LTC4413EDD#TRPBF is ROHS3 Compliant, meeting current regulatory requirements for electronic components in consumer and industrial applications.

• Electrical Performance: The LTC4413EDD#TRPBF meets or exceeds the output current specification (2.6A versus 2.5A) and operates with lower supply current (25 µA versus 30 µA), providing improved power efficiency.

• Voltage Supply Range: The LTC4413EDD#TRPBF operates within 2.5V ~ 5.5V. Applications requiring operation below 2.5V must evaluate the 0.2V minimum voltage offset against system requirements.

• Package Transition: Substitution requires PCB layout redesign due to package geometry change from 16-WLCSP to 10-DFN. Thermal and electrical routing characteristics differ between packages and must be re-evaluated during design integration.

Frequently Asked Questions (FAQ)

Q: Can the LTC4413EDD#TRPBF directly replace the FPF3003UCX without PCB modifications?

A: No. The LTC4413EDD#TRPBF uses a 10-DFN package (3x3mm) while the FPF3003UCX uses a 16-WLCSP package (1.71x1.71mm). PCB layout redesign is required, including footprint changes, trace routing, and thermal management evaluation.

Q: What is the minimum supply voltage difference between these parts?

A: The FPF3003UCX operates from 2.3V minimum, while the LTC4413EDD#TRPBF operates from 2.5V minimum. This 0.2V difference must be evaluated for applications operating near the lower voltage boundary.

Q: Are both parts suitable for handheld and mobile device applications?

A: Yes. Both the FPF3003UCX and LTC4413EDD#TRPBF are specified for handheld and mobile device applications and share identical 2:1 source selector switch functionality for dual power source management.

Q: What is the significance of the Obsolete status for the FPF3003UCX?

A: Obsolete status indicates the FPF3003UCX is no longer manufactured by onsemi and is not available through standard distribution channels. The LTC4413EDD#TRPBF, with Active status, ensures continued availability and manufacturing support.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the FPF3003UCX and LTC4413EDD#TRPBF are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Is the LTC4413EDD#TRPBF RoHS compliant?

A: Yes. The LTC4413EDD#TRPBF is ROHS3 Compliant. RoHS compliance status for the FPF3003UCX was not specified in the original documentation.
