FPF2110 Equivalent & Substitute Parts

Part Overview

The FPF2110 is a Power Switch/Driver IC from onsemi's IntelliMAX™ series, designed for high-side P-channel switching applications. This component operates as a 1:1 power switch with 400mA maximum output current and integrated fault protection including current limiting, over-temperature monitoring, reverse current protection, and UVLO (Under-Voltage Lock-Out). The FPF2110 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design alternatives.

Substitute Part Grouping Explanation

Substitute parts for the FPF2110 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output Configuration: High Side switching
• Output Type: P-Channel
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Voltage - Load Range: 1.8V ~ 5.5V
• Current - Output (Max): 400mA minimum
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Fault Protection: Current Limiting, Over Temperature, Reverse Current, UVLO
• Interface: On/Off control

The FPF2108 qualifies as a parametric equivalent based on its identical functional architecture as a Power Switch/Driver with matching output configuration and protection features.

Parameter Comparison

Engineering Selection Recommendations

FPF2108 as Primary Substitute:

The FPF2108 is classified as Active product status, providing ongoing manufacturer support and availability compared to the obsolete FPF2110. Both components share the Power Management (PMIC) category and Power Switch/Driver functional classification. The FPF2108 maintains REACH Unaffected compliance status, consistent with the main part.

Selection of the FPF2108 is appropriate for applications requiring continued supply chain support and modern component lifecycle management. The transition from FPF2110 (obsolete) to FPF2108 (active) aligns with standard engineering practice for end-of-life component replacement.

Frequently Asked Questions (FAQ)

Q: What makes FPF2108 a suitable substitute for FPF2110?

A: The FPF2108 is a parametric equivalent Power Switch/Driver IC with matching functional architecture for high-side P-channel switching. Both components operate within the same voltage and current specifications required for 1:1 power switching applications with integrated fault protection.

Q: Are there package compatibility considerations between FPF2110 and FPF2108?

A: Both components utilize the SOT-23-5 package format (SC-74A, SOT-753), ensuring direct PCB footprint compatibility. Surface mount placement and soldering processes remain identical between the two parts.

Q: What is the significance of the FPF2110's obsolete status?

A: Obsolete status indicates the FPF2110 is no longer manufactured or supported by onsemi. The FPF2108, classified as Active, provides continued availability and manufacturer technical support, making it the recommended choice for new designs and ongoing production requirements.

Q: How do compliance certifications compare between these parts?

A: Both the FPF2110 and FPF2108 maintain REACH Unaffected status. The FPF2110 is explicitly ROHS3 Compliant. The FPF2108's RoHS compliance status is not specified in available documentation.

Q: Are there differences in moisture sensitivity between these components?

A: The FPF2110 specifies MSL 1 (Unlimited), indicating minimal moisture sensitivity. The FPF2108's MSL is listed as Vendor Undefined. Consult Fairchild Semiconductor technical documentation for specific moisture handling requirements.
