FPF2100 Equivalent & Substitute Parts

Part Overview

The FPF2100 is a Power Switch/Driver IC from onsemi's IntelliMAX™ series, designed as a high-side P-channel power switch with 1:1 configuration and 200mA output capability in SOT-23-5 surface mount packaging. The device is classified as Obsolete, making identification of equivalent substitute parts essential for ongoing design support and component procurement. Substitute parts must maintain identical electrical performance, package compatibility, and functional characteristics to ensure direct replacement capability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FPF2100 are qualified based on the following critical parameters that determine functional equivalence:

• Output Type: P-Channel high-side configuration
• Current Rating: 200mA maximum output current
• Load Voltage Range: 1.8V ~ 5.5V
• On-Resistance: 125mOhm typical
• Package: SOT-23-5 (SC-74A, SOT-753)
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO
• Interface: On/Off control with Non-Inverting input
• Features: Auto Restart and Status Flag capability

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The FPF2100 and FPF2101 are parametric equivalents with identical electrical specifications, package configuration, and protection features. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between these parts may be based on inventory availability and supplier lead times, as both devices provide equivalent functionality for high-side P-channel power switching applications in the 1.8V to 5.5V load voltage range.

Frequently Asked Questions (FAQ)

Q: Can FPF2101 directly replace FPF2100 in existing designs? A: Yes. The FPF2101 is a parametric equivalent with identical electrical characteristics, output configuration, current rating, on-resistance, fault protection features, and SOT-23-5 package. Direct substitution is supported without circuit modification.

Q: Are there any differences in package dimensions between FPF2100 and FPF2101? A: No. Both parts use the same SOT-23-5 package (SC-74A, SOT-753) with identical pin configuration and mechanical dimensions, ensuring PCB layout compatibility.

Q: What are the key parameters that define substitution eligibility for this part? A: Substitution eligibility is determined by: P-channel high-side output configuration, 200mA maximum current rating, 1.8V to 5.5V load voltage range, 125mOhm typical on-resistance, SOT-23-5 package, and identical fault protection features (current limiting, over-temperature, UVLO).

Q: Are both parts suitable for applications requiring ROHS3 compliance? A: Yes. Both FPF2100 and FPF2101 are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level), meeting current environmental standards for commercial and industrial applications.

Q: What is the significance of the Obsolete product status? A: Obsolete status indicates that the FPF2100 is no longer in active production. The FPF2101 substitute provides continued design support and component availability for applications currently using the FPF2100.
