FPF1018 Equivalent & Substitute Parts

Part Overview

The FPF1018 is a Power Switch/Driver IC in the IntelliMAX™ series, designed for high-side N-channel switching applications. This component features a 1:1 input-to-output ratio with 1.5A maximum output current and operates across a load voltage range of 0.8V to 1.8V. The part is packaged in a 6-VDFN Exposed Pad surface mount configuration.

The original FPF1018 from onsemi carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FPF1018 is determined by strict alignment across the following critical parameters:

• Output configuration and type (High Side, N-Channel)
• Maximum output current rating (1.5A)
• On-resistance specification (34mOhm typical)
• Load voltage operating range (0.8V ~ 1.8V)
• Package and pinout compatibility (6-VDFN Exposed Pad)
• Operating temperature range (-40°C ~ 85°C)
• Functional features (Load Discharge, Slew Rate Controlled)
• Input interface type (Non-Inverting, On/Off)

Parts meeting all these criteria are classified as direct parametric equivalents and may be used interchangeably in circuit designs without modification.

Parameter Comparison

Engineering Selection Recommendations

The FPF1018 from onsemi is classified as Obsolete, necessitating alternative sourcing for new designs and ongoing production support. Both substitute options—FPF1016 from Fairchild Semiconductor and FPF1018 from Fairchild Semiconductor—are Active products with identical electrical and mechanical specifications.

The FPF1018 from Fairchild Semiconductor represents a direct manufacturer equivalent with matching part number and full parametric alignment. This option provides the most straightforward replacement path.

The FPF1016 from Fairchild Semiconductor is a parametric equivalent offering identical electrical performance and package compatibility. This part is suitable where supply or cost considerations favor an alternative part number within the same functional class.

Both substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original component. Selection between these options should be based on availability, lead time, and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can FPF1016 be used as a direct replacement for FPF1018?

A: Yes. The FPF1016 meets all critical substitution parameters: identical output configuration, current rating, on-resistance, load voltage range, package type, and operating temperature. Both parts are from the IntelliMAX™ series and share the same functional feature set.

Q: What is the difference between the onsemi FPF1018 and Fairchild FPF1018?

A: Both parts are electrically and mechanically identical. The primary difference is manufacturer and product status. The onsemi version is Obsolete, while the Fairchild version is Active. The Fairchild FPF1018 is the recommended replacement for the onsemi original.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 6-VDFN Exposed Pad surface mount package with identical pinout and mechanical dimensions. Direct PCB substitution is supported without layout modifications.

Q: Do these parts require different handling or storage procedures?

A: All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to all surface mount components.

Q: What compliance certifications apply to these substitute parts?

A: All parts are ROHS3 Compliant and REACH Unaffected. The FPF1016 and Fairchild FPF1018 maintain full regulatory alignment with the original onsemi FPF1018.
