FPF2001 Equivalent & Substitute Parts

Part Overview

The FPF2001 is a power switch/driver IC from onsemi's IntelliMAX™ series, designed for high-side P-channel switching applications. This component features a 1:1 input-to-output ratio with 50mA maximum output current and operates across a 1.8V to 5.5V load voltage range. The FPF2001 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FPF2001 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Output Type: P-Channel
• Output Configuration: High Side
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Interface: On/Off
• Input Type: Non-Inverting
• Package / Case: 5-TSSOP, SC-70-5, SOT-353
• Mounting Type: Surface Mount

Allowable Parameter Variations:

• Voltage - Load: Must support the minimum 1.8V requirement; higher maximum ratings are acceptable
• Current - Output (Max): Must meet or exceed 50mA requirement
• Rds On (Typ): Lower values are acceptable; higher values require circuit validation
• Operating Temperature: Extended ranges are acceptable
• Fault Protection: Additional protection features are acceptable; existing protections must be maintained
• Product Status: Active parts are preferred for obsolete parts; obsolete parts remain functionally equivalent

Parameter Comparison

Engineering Selection Recommendations

FPF2000 (onsemi): This part is a parametric equivalent to the FPF2001, matching all critical electrical and mechanical specifications. Both parts are classified as obsolete. The FPF2000 is suitable for direct replacement in existing designs where the FPF2001 is no longer available. Both parts maintain identical voltage, current, and thermal characteristics.

TPS22941DCKR (Texas Instruments): This part is a functional substitute with the following considerations: The TPS22941DCKR is an active product, providing long-term availability compared to the obsolete FPF2001. The maximum output current is 40mA, which is lower than the FPF2001's 50mA specification. The on-resistance is 400mOhm, providing superior performance compared to the FPF2001's 700mOhm. The operating temperature range extends to 125°C, exceeding the FPF2001's 85°C maximum. The TPS22941DCKR lacks the Status Flag feature present in the FPF2001. All three parts share identical packaging, mounting type, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the FPF2000 be used as a direct replacement for the FPF2001?

A: Yes. The FPF2000 is a parametric equivalent with identical electrical specifications, including voltage range, maximum output current, on-resistance, and fault protection features. Both parts use the same SC-70-5 package and mounting type. The primary difference is product status; both are obsolete.

Q: Is the TPS22941DCKR suitable for applications requiring 50mA output current?

A: The TPS22941DCKR has a maximum output current rating of 40mA, which is 10mA lower than the FPF2001's 50mA specification. Applications requiring the full 50mA output current must use the FPF2001 or FPF2000. Applications with maximum current requirements of 40mA or less can use the TPS22941DCKR.

Q: What is the impact of the TPS22941DCKR's lower on-resistance?

A: The TPS22941DCKR's 400mOhm on-resistance is superior to the FPF2001's 700mOhm specification. Lower on-resistance reduces power dissipation and heat generation in the switch, improving overall circuit efficiency. This is a beneficial characteristic for substitution.

Q: Does the absence of the Status Flag feature in the TPS22941DCKR affect compatibility?

A: The Status Flag is a monitoring feature present in the FPF2001 and FPF2000 but absent in the TPS22941DCKR. If the design does not utilize the Status Flag output, this difference has no impact. Designs that depend on Status Flag monitoring must use the FPF2001 or FPF2000.

Q: Are all three parts RoHS3 compliant?

A: Yes. The FPF2001, FPF2000, and TPS22941DCKR are all ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards.

Q: Can the TPS22941DCKR be used in applications with extended temperature requirements?

A: Yes. The TPS22941DCKR operates across -40°C to 125°C (TJ), exceeding the FPF2001's -40°C to 85°C (TA) range. This extended temperature capability makes the TPS22941DCKR suitable for applications requiring higher temperature operation.
