FPF1014 Equivalent & Substitute Parts

Part Overview

The FPF1014 is an N-Channel power switch/driver IC manufactured by onsemi, designed for high-side switching applications with a 1:1 input-to-output ratio. This component operates at 1.5A maximum output current with a typical on-resistance of 17mOhm and supports load voltages from 0.8V to 1.8V. The device is packaged in a 6-WLCSP (0.96x1.66mm) form factor and operates across the industrial temperature range of -40°C to 85°C.

The FPF1014 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute components must maintain functional equivalence in switching topology, output configuration, and thermal operating range while accommodating variations in current capacity, on-resistance, and load voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FPF1014 is determined by the following critical parameters:

• Output Type & Configuration: N-Channel, High Side switching topology
• Switching Ratio: 1:1 input-to-output
• Operating Temperature Range: -40°C to 85°C (TA)
• Interface Type: On/Off control, Non-Inverting input
• Load Voltage Compatibility: Minimum overlap with 0.8V ~ 1.8V range
• Current Capacity: Minimum 1.5A output current
• On-Resistance: Comparable performance (17mOhm reference)
• Package Form Factor: Surface mount, 6-pin BGA variants
• Features: Load Discharge and Slew Rate Controlled capability

Substitute parts are grouped into two categories:

Category A - N-Channel Direct Substitutes: Parts maintaining N-Channel output type with equivalent or superior electrical performance.

Category B - P-Channel Functional Alternatives: Parts with P-Channel output type, suitable only for applications where channel polarity can be accommodated in circuit design.

Engineering Selection Recommendations

N-Channel Substitutes (Direct Functional Equivalents)

TCK112G,LF (Toshiba) provides the closest functional match with N-Channel output topology and 1:1 switching ratio. This part exceeds FPF1014 specifications with 3A output current capacity and 8.3mOhm on-resistance. Load voltage range of 1.1V ~ 5.5V encompasses the original 0.8V ~ 1.8V specification. The device is active and ROHS3 compliant. Enhanced fault protection (Over Temperature, Reverse Current) provides additional circuit safeguards. Package form factor is 6-WCSPC (1.5x1.0mm), requiring PCB layout verification for pin compatibility.

TPS22924BYZR and TPS22924BYZT (Texas Instruments) maintain N-Channel output configuration with 2A current capacity and 18.3mOhm on-resistance. Load voltage range of 0.75V ~ 3.6V provides extended lower-voltage capability below the FPF1014 minimum. Both variants are active and ROHS3 compliant. TPS22924BYZR is supplied in Cut Tape packaging; TPS22924BYZT is supplied in Tape & Reel. Package form factor is 6-DSBGA, requiring verification against original 6-WLCSP footprint.

P-Channel Functional Alternatives

TPS22922BYZPR, TPS22922YZPR, and TPS22921YZPR (Texas Instruments) feature P-Channel output topology with 1:1 switching ratio and 2A output current. These parts are suitable only for applications where circuit topology permits P-Channel substitution. Load voltage range of 0.9V ~ 3.6V overlaps with the original specification. All variants are active and ROHS3 compliant. TPS22922 series includes Load Discharge feature; TPS22921 does not. Packaging is 6-DSBGA, requiring footprint compatibility assessment.

Compliance & Availability

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, matching the original FPF1014 compliance profile. All active substitutes are ROHS3 compliant. Inventory availability ranges from 2,295 to 54,073 units across substitute options, supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can TCK112G,LF directly replace FPF1014 in existing PCB layouts?

A: TCK112G,LF maintains N-Channel, High Side, 1:1 topology and identical operating temperature range. However, the package form factor differs (6-WCSPC vs. 6-WLCSP). PCB footprint, pin pitch, and solder pad dimensions must be verified for mechanical and electrical compatibility before implementation.

Q: What is the primary difference between TPS22924BYZR and TPS22924BYZT?

A: Both parts are electrically identical N-Channel power switches with 2A output current and 18.3mOhm on-resistance. The difference is packaging format: TPS22924BYZR is supplied in Cut Tape (CT) & Digi-Reel; TPS22924BYZT is supplied in Tape & Reel (TR). Selection depends on assembly equipment and procurement requirements.

Q: Why are P-Channel parts (TPS22922, TPS22921) listed as substitutes for an N-Channel device?

A: P-Channel parts are listed as functional alternatives for applications where circuit design permits channel polarity reversal. These are not direct pin-for-pin replacements but represent equivalent switching functionality with different gate drive requirements. Use only if circuit topology supports P-Channel operation.

Q: Does TCK112G,LF provide better performance than the original FPF1014?

A: TCK112G,LF exceeds FPF1014 specifications in output current capacity (3A vs. 1.5A) and on-resistance (8.3mOhm vs. 17mOhm). Load voltage range is extended (1.1V ~ 5.5V vs. 0.8V ~ 1.8V). Enhanced fault protection (Over Temperature, Reverse Current) is included. These improvements provide design margin and additional circuit protection.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original FPF1014 compliance status is not specified in available data. Verify compliance requirements against your specific application and regulatory jurisdiction.

Q: What load voltage range is common across all substitutes?

A: No single voltage range is common to all parts. The original FPF1014 operates at 0.8V ~ 1.8V. TCK112G,LF supports 1.1V ~ 5.5V. TPS22924 series supports 0.75V ~ 3.6V. TPS22922 and TPS22921 support 0.9V ~ 3.6V. Application load voltage must fall within the selected substitute's specification.

Q: Can I use TPS22921YZPR as a substitute if my circuit uses N-Channel switching?

A: TPS22921YZPR is a P-Channel device and cannot be used as a direct substitute in N-Channel switching circuits without circuit redesign. Use N-Channel alternatives (TCK112G,LF, TPS22924BYZR, TPS22924BYZT) for N-Channel applications.
