Key Parameters

Substitute Part Grouping Explanation

Substitution for the FPF2102 is determined by strict equivalence across the following critical parameters:

• Output Type: P-Channel high-side configuration
• Current Rating: 200mA maximum output
• Load Voltage Range: 1.8V ~ 5.5V
• On-Resistance: 125mOhm typical
• Package: SOT-23-5 (SC-74A, SOT-753)
• Interface: On/Off control with non-inverting input
• Protection Features: Current limiting, over-temperature, and UVLO
• Compliance: ROHS3 compliant

The FPF2103 meets all these criteria as a parametric equivalent within the IntelliMAX™ series.

Parameter Comparison

Engineering Selection Recommendations

The FPF2103 is a direct parametric equivalent to the FPF2102. Both components share identical electrical specifications, package form factor, and compliance certifications. Selection between these parts should be based on availability and procurement lead times, as both are classified as obsolete products. The FPF2103 maintains full compatibility with existing PCB layouts and circuit designs utilizing the FPF2102.

Frequently Asked Questions (FAQ)

Q: Can the FPF2103 replace the FPF2102 in existing designs? A: Yes. The FPF2103 is a parametric equivalent with identical electrical characteristics, output configuration, current rating, voltage range, on-resistance, and package specifications. Direct substitution is supported without circuit modification.

Q: Are there any differences in the SOT-23-5 package between these parts? A: No. Both the FPF2102 and FPF2103 use the SC-74A/SOT-753 package designation. Pin configuration and PCB footprint compatibility are maintained.

Q: What is the significance of the obsolete product status? A: Both parts are classified as obsolete, indicating they are no longer in active production. Component selection should prioritize available inventory from authorized distributors. The FPF2103 may offer better availability in certain regions or through specific supply channels.

Q: Are both parts RoHS compliant? A: Yes. Both the FPF2102 and FPF2103 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What protection features are included in both parts? A: Both components include current limiting (fixed), over-temperature protection, and UVLO (under-voltage lockout) fault protection with status flag indication.
