FPF1005 Equivalent & Substitute Parts

Part Overview

The FPF1005 is a Power Switch/Driver IC from onsemi's IntelliMAX™ series, configured as a 1:1 P-Channel high-side switch with 1.5A output capability in a 6-MicroFET (2x2) package. The device is classified as Obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Alternative parts must maintain functional compatibility across load voltage range, output current rating, and thermal operating conditions while accommodating packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. The FPF1005 substitutes are grouped into two categories:

Parametric Equivalents (FPF1006, FPF1007, FPF1008): These parts maintain identical or superior electrical performance within the allowed parameter ranges. All three share the same output current rating (1.5A), load voltage range (1.2V ~ 5.5V), package footprint (6-MicroFET 2x2), interface type (On/Off, Non-Inverting), and feature set (Load Discharge, Slew Rate Controlled). Differences in Rds On values (30mOhm vs. 50mOhm) represent performance improvements rather than incompatibilities. Packaging variants (6-WDFN vs. 6-VDFN) are mechanically compatible within the same footprint class.

Similar Part (AP2281-3FMG-7): This Diodes Incorporated device operates within an expanded load voltage range (1.5V ~ 6V) and higher output current (2A), with a different package designation (6-UFDFN). While functionally similar in topology and interface, the AP2281-3FMG-7 represents a higher-performance alternative suitable for applications requiring increased current capacity or voltage headroom.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: FPF1006

FPF1006 is the preferred direct replacement for FPF1005. Both parts are onsemi IntelliMAX™ series devices with identical electrical specifications (1.5A output, 50mOhm Rds On, 1.2V ~ 5.5V load voltage range) and package footprint (6-WDFN Exposed Pad). FPF1006 holds Active product status, ensuring long-term availability and supply chain stability. Packaging is available in Cut Tape format, matching the original FPF1005 distribution method. ROHS3 compliance and MSL 1 rating are maintained.

Secondary Recommendation: FPF1007 or FPF1008

FPF1007 and FPF1008 offer improved electrical performance with reduced Rds On (30mOhm vs. 50mOhm), resulting in lower power dissipation and improved thermal characteristics. FPF1008 is sourced from Fairchild Semiconductor and maintains Active product status. Both devices support identical load voltage ranges and output current ratings. Package compatibility is maintained within the 6-MicroFET (2x2) footprint class. Selection between these options depends on supply chain availability and packaging format requirements (Cut Tape vs. Bulk).

Alternative Consideration: AP2281-3FMG-7

The AP2281-3FMG-7 from Diodes Incorporated is suitable for applications requiring higher output current (2A) or expanded load voltage range (1.5V ~ 6V). This part maintains Active product status and ROHS3 compliance. The higher Rds On value (80mOhm) represents a trade-off against increased current capacity. Package designation (6-UFDFN) differs from the original but maintains mechanical compatibility within DFN form factor constraints. Selection of this part should be limited to designs where the enhanced specifications provide functional advantage.

Frequently Asked Questions (FAQ)

Q: Can FPF1006 be used as a direct drop-in replacement for FPF1005?

A: Yes. FPF1006 maintains identical electrical specifications (1.5A output current, 50mOhm Rds On, 1.2V ~ 5.5V load voltage range) and package footprint (6-WDFN Exposed Pad). Both are onsemi IntelliMAX™ series devices with matching interface and feature sets. The primary difference is product status: FPF1006 is Active while FPF1005 is Obsolete.

Q: What is the difference between FPF1007 and FPF1008?

A: Both parts offer identical electrical performance (1.5A output, 30mOhm Rds On, 1.2V ~ 5.5V load voltage) and maintain the same interface and feature set. The primary differences are manufacturer (onsemi vs. Fairchild Semiconductor), package designation (6-WDFN vs. 6-VDFN), and packaging format (Cut Tape & Digi-Reel vs. Bulk). Both are mechanically compatible within the 6-MicroFET (2x2) footprint class.

Q: When should AP2281-3FMG-7 be selected over FPF1006?

A: AP2281-3FMG-7 is appropriate when the application requires output current exceeding 1.5A (rated to 2A) or load voltage exceeding 5.5V (rated to 6V). The higher Rds On value (80mOhm) results in increased power dissipation compared to FPF1006 (50mOhm). Selection should be based on specific circuit requirements rather than as a general replacement.

Q: Are all substitute parts ROHS3 compliant?

A: FPF1006, FPF1007, and AP2281-3FMG-7 are confirmed ROHS3 compliant. FPF1008 RoHS status is not specified in the provided data. Compliance verification is required before final part selection for regulated applications.

Q: What packaging formats are available for these parts?

A: FPF1005 and FPF1007 are available in Cut Tape (CT) and Digi-Reel® formats. FPF1006 is available in Cut Tape (CT) format. FPF1008 is available in Bulk format. AP2281-3FMG-7 is available in Tape & Reel (TR) format. Packaging selection depends on production volume and supply chain requirements.

Q: Do all parts maintain the same operating temperature range?

A: Yes. All substitute parts (FPF1006, FPF1007, FPF1008, AP2281-3FMG-7) operate across the identical temperature range of -40°C ~ 85°C (TA), matching the FPF1005 specification.
