IPS1031PBF Equivalent & Substitute Parts

Part Overview

The IPS1031PBF is a Power Switch/Driver N-Channel 1:1 configuration rated for 9.5A maximum output current in a TO-220AB package, manufactured by Infineon Technologies. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. Substitute parts must maintain compatibility across critical electrical parameters including output configuration, switching topology, and thermal operating range to ensure direct replacement capability.

Engineering Selection Recommendations

VNP20N07-E provides direct functional substitution for applications requiring output current up to 14A. This part maintains active product status with ROHS3 compliance and extends load voltage rating to 55V, offering enhanced design margin. The addition of over-voltage protection represents an improvement over the original IPS1031PBF specification.

VNP35N07-E serves applications requiring maximum output current up to 25A within the same TO-220-3 package. This part also maintains active product status and ROHS3 compliance. The higher current rating accommodates designs with increased power delivery requirements while preserving the identical package footprint and control interface.

Both substitute parts are manufactured by STMicroelectronics and carry REACH compliance status equivalent to the original component. Selection between VNP20N07-E and VNP35N07-E depends solely on application current requirements and thermal management considerations.

Frequently Asked Questions (FAQ)

Q: Can VNP20N07-E or VNP35N07-E be used as direct pin-for-pin replacements for IPS1031PBF?

A: Yes. Both substitute parts maintain identical TO-220-3 package pinout and on/off control interface, enabling direct PCB substitution without layout modification.

Q: What is the primary difference between VNP20N07-E and VNP35N07-E?

A: The VNP20N07-E is rated for 14A maximum output current, while VNP35N07-E is rated for 25A. Both share identical package, control interface, and 55V load voltage rating. Selection depends on application current requirements.

Q: Why is the IPS1031PBF classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Infineon Technologies. VNP20N07-E and VNP35N07-E are active products from STMicroelectronics providing equivalent functionality with enhanced specifications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both VNP20N07-E and VNP35N07-E carry ROHS3 compliance certification. The original IPS1031PBF RoHS status is not specified in available documentation.

Q: What additional protection features do the substitute parts provide?

A: VNP20N07-E and VNP35N07-E include over-voltage protection in addition to current limiting and over-temperature protection present in the IPS1031PBF. Both parts also include status flag output capability.

Q: Can I use VNP35N07-E in an application originally designed for IPS1031PBF?

A: Yes, provided thermal management accommodates the higher current rating. The 25A capability of VNP35N07-E exceeds IPS1031PBF requirements, making it suitable for direct substitution in any application within the 28V load voltage envelope.
