FPF2106 Equivalent & Substitute Parts

Part Overview

The FPF2106 is a Power Switch/Driver IC from onsemi's IntelliMAX™ series, configured as a 1:1 P-Channel high-side switch with 400mA output capability in SOT-23-5 surface mount packaging. This component is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part integrates on/off control with integrated fault protection including current limiting, over-temperature monitoring, and under-voltage lockout (UVLO).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FPF2106 is determined by strict parametric matching across the following critical dimensions:

Electrical Parameters: Output type (P-Channel), output configuration (High Side), current rating (400mA), on-state resistance (125mOhm typical), load voltage range (1.8V ~ 5.5V), and integrated protection features (current limiting, over-temperature, UVLO).

Mechanical Parameters: Package type (SOT-23-5), surface mount configuration, and pin compatibility.

Compliance Parameters: RoHS3 compliance status and moisture sensitivity level (MSL 1).

The FPF2107 meets all specified parameters and qualifies as a parametric equivalent substitute for the FPF2106.

Parameter Comparison

Engineering Selection Recommendations

The FPF2107 is a direct parametric equivalent to the FPF2106 and is suitable for replacement in applications requiring identical electrical and mechanical specifications. Both parts are classified as Obsolete; however, the FPF2107 maintains higher current inventory availability (2122 pcs vs. 20963 pcs for FPF2106). Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in new designs and legacy support applications. Selection between these parts should be based on inventory availability and lead time requirements rather than technical differentiation.

Frequently Asked Questions (FAQ)

Q: Can the FPF2107 be used as a direct replacement for the FPF2106?

A: Yes. The FPF2107 is a parametric equivalent with identical electrical specifications (400mA output, 125mOhm Rds On, 1.8V ~ 5.5V load voltage), identical fault protection features, and identical SOT-23-5 packaging. No circuit modifications are required.

Q: Are there any differences in pin configuration between FPF2106 and FPF2107?

A: No. Both parts use the SOT-23-5 package (SC-74A, SOT-753) with identical pin assignments. PCB layouts and footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both FPF2106 and FPF2107 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. They are suitable for equivalent regulatory and environmental applications.

Q: Why is the FPF2106 listed as Obsolete?

A: Product obsolescence is a manufacturer lifecycle designation. The FPF2107 is also classified as Obsolete but remains available through current inventory channels. For long-term production requirements, consult onsemi for extended availability or alternative solutions.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching output type (P-Channel), output configuration (High Side 1:1), current rating (400mA), on-state resistance (125mOhm), load voltage range (1.8V ~ 5.5V), protection features (current limiting, over-temperature, UVLO), and package type (SOT-23-5). The FPF2107 matches all these parameters.
