FPF1009 Equivalent & Substitute Parts

Part Overview

The FPF1009 is a Power Switch/Driver IC manufactured by onsemi, designed for high-side P-channel switching applications. This component operates as a 1:1 power switch with a maximum output current of 1.5A and is housed in a 6-MicroFET (2x2) package. The FPF1009 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and component procurement in legacy systems or when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FPF1009 is determined by strict equivalence across the following critical parameters:

• Output Type: P-Channel high-side switch
• Ratio - Input:Output: 1:1 configuration
• Current - Output (Max): 1.5A
• Voltage - Load: 1.2V ~ 5.5V operating range
• Rds On (Typ): 30mOhm on-resistance
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 6-MicroFET (2x2) form factor

The FPF1007 and FPF1008 meet all these electrical and mechanical criteria, establishing them as parametric equivalents suitable for direct substitution in applications requiring the FPF1009.

Parameter Comparison

Engineering Selection Recommendations

The FPF1007 and FPF1008 are direct parametric equivalents to the FPF1009 across all critical electrical and mechanical specifications. Selection between these substitutes should be based on the following factors:

FPF1007 is manufactured by onsemi, maintaining consistency with the original FPF1009 manufacturer. Both the FPF1009 and FPF1007 are classified as obsolete products. The FPF1007 carries ROHS3 compliance certification, matching the environmental compliance profile of the FPF1009.

FPF1008 is manufactured by Fairchild Semiconductor and maintains active product status, offering potential long-term availability advantages. The FPF1008 uses a 6-VDFN package variant compared to the 6-WDFN package of the FPF1009 and FPF1007. This package difference requires physical verification for PCB footprint compatibility, though both are 6-MicroFET (2x2) form factors with identical electrical performance.

For applications requiring strict manufacturer continuity and compliance documentation, FPF1007 is the preferred substitute. For applications where long-term component availability is prioritized, FPF1008 is the recommended alternative, provided PCB layout accommodates the VDFN package variant.

Frequently Asked Questions (FAQ)

Q: Can FPF1007 or FPF1008 be used as direct replacements for FPF1009 in existing designs?

A: Yes. Both FPF1007 and FPF1008 are parametric equivalents meeting all electrical specifications: 1.5A maximum output current, 30mOhm on-resistance, 1.2V to 5.5V load voltage range, and identical operating temperature range. Both are housed in 6-MicroFET (2x2) packages suitable for surface mount assembly.

Q: What is the difference between the 6-WDFN and 6-VDFN packages?

A: Both packages are 6-MicroFET (2x2) form factors with identical electrical performance and pin configuration. The primary difference is the package designation variant. PCB footprint compatibility must be verified during design transition, as minor dimensional variations may exist between WDFN and VDFN designations.

Q: Why is FPF1008 listed as active while FPF1009 and FPF1007 are obsolete?

A: Product status reflects manufacturer lifecycle classifications. FPF1008's active status indicates ongoing manufacturing and availability from Fairchild Semiconductor, whereas FPF1009 and FPF1007 have been discontinued by onsemi. For new designs or long-term production requirements, FPF1008 offers superior supply chain continuity.

Q: Are there compliance differences between these substitutes?

A: FPF1009 and FPF1007 are both ROHS3 compliant. FPF1008 compliance status is not specified in available documentation. For applications requiring specific environmental compliance certifications, verify FPF1008 documentation with the manufacturer or distributor before selection.

Q: What inventory considerations apply to these substitutes?

A: FPF1009 has 53,300 pieces in stock, FPF1007 has 8,640 pieces, and FPF1008 has 1,766 pieces. Inventory levels reflect current availability but should not be the sole basis for component selection. Long-term design decisions should prioritize FPF1008 due to its active product status, despite lower current inventory.
