FPF2007 Equivalent & Substitute Parts

Part Overview

The FPF2007 is a Power Management Integrated Circuit (PMIC) manufactured by onsemi, functioning as a high-side P-channel power switch with 1:1 input-to-output ratio. This device is classified as a general-purpose load switch designed for low-voltage applications requiring controlled power distribution. The FPF2007 operates in the 1.8V to 5.5V load voltage range with a maximum output current of 100mA and typical on-resistance of 700mOhm.

The FPF2007 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FPF2007 are qualified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• Output Configuration: High Side, P-Channel (1:1 ratio)
• Package / Case: 5-TSSOP, SC-70-5, SOT-353 (identical footprint)
• Interface: On/Off control
• Input Type: Non-Inverting
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO
• Voltage - Load: Minimum 1.8V support required
• Current - Output (Max): Minimum 100mA capability required
• Mounting Type: Surface Mount

Allowable Parameter Variations:

• Rds On (Typ): Lower values are acceptable (improved performance)
• Operating Temperature Range: Extended ranges are acceptable
• Product Status: Active status preferred for ongoing availability
• Additional Features: Auto Restart and Status Flag are acceptable enhancements

Three substitute parts meet these criteria: FPF2004 (Fairchild Semiconductor), TPS22943DCKR (Texas Instruments), and TPS22944DCKR (Texas Instruments).

Parameter Comparison

Engineering Selection Recommendations

FPF2004 (Fairchild Semiconductor)

The FPF2004 provides direct electrical equivalence to the FPF2007 with identical load voltage range (1.8V ~ 5.5V), maximum output current (100mA), and on-resistance (700mOhm). This part maintains active product status, ensuring long-term availability and supply chain continuity. The FPF2004 includes Auto Restart functionality as an additional feature beyond the FPF2007 specification. Identical package and footprint compatibility (SC-70-5) enables direct board-level substitution without layout modifications.

TPS22944DCKR (Texas Instruments)

The TPS22944DCKR matches the FPF2007 in maximum output current (100mA) and maintains identical package compatibility (SC-70-5). This part offers improved on-resistance (400mOhm versus 700mOhm), resulting in lower power dissipation and improved thermal performance. The TPS22944DCKR supports an extended operating temperature range (-40°C ~ 125°C) and carries active product status with RoHS3 compliance certification. The load voltage range extends to 1.62V, providing broader application support. This part is suitable for applications where improved electrical performance and extended temperature operation are beneficial.

TPS22943DCKR (Texas Instruments)

The TPS22943DCKR shares identical package compatibility (SC-70-5) and fault protection architecture with the FPF2007. This part is not recommended as a direct substitute due to maximum output current limitation (40mA versus 100mA required). The TPS22943DCKR is suitable only for applications with current requirements not exceeding 40mA. This part offers improved on-resistance (400mOhm) and extended operating temperature range (-40°C ~ 125°C) with active product status and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the FPF2004 be used as a direct replacement for the FPF2007?

A: Yes. The FPF2004 provides complete electrical and mechanical compatibility. Both parts operate in the 1.8V ~ 5.5V load voltage range, support 100mA maximum output current, and use identical SC-70-5 packaging. No circuit modifications or board redesign are required.

Q: What is the primary difference between TPS22944DCKR and FPF2007?

A: The TPS22944DCKR offers improved on-resistance (400mOhm versus 700mOhm) and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C). Both parts maintain identical load voltage range (1.62V ~ 5.5V for TPS22944DCKR, 1.8V ~ 5.5V for FPF2007) and 100mA output current capability. Package compatibility is identical (SC-70-5).

Q: Why is TPS22943DCKR not recommended as a substitute?

A: The TPS22943DCKR has a maximum output current rating of 40mA, which is insufficient for applications requiring the FPF2007's 100mA capability. This part is only suitable for low-current applications below 40mA.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts (FPF2004, TPS22943DCKR, TPS22944DCKR) use the 5-TSSOP, SC-70-5, SOT-353 package. Direct board-level substitution is possible without layout modifications.

Q: What is the supply status of these substitute parts?

A: FPF2004, TPS22943DCKR, and TPS22944DCKR all carry active product status, ensuring ongoing availability and supply chain support. The original FPF2007 is obsolete.

Q: Do the substitute parts support the same voltage range as FPF2007?

A: FPF2004 supports identical load voltage range (1.8V ~ 5.5V). TPS22943DCKR and TPS22944DCKR support extended range (1.62V ~ 5.5V), which includes the FPF2007 operating window and provides additional low-voltage capability.
