IPS031S Equivalent & Substitute Parts

Part Overview

The IPS031S is an N-Channel power switch/driver manufactured by Infineon Technologies, designed for general-purpose low-side switching applications. This device features a 1:1 input-to-output ratio with a maximum load voltage of 35V and output current capability of 2.8A in a D2PAK surface-mount package. The IPS031S is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IPS031S is determined by the following critical parameters:

• Package Compatibility: All substitute parts must use the D2PAK (TO-263-3) surface-mount package to ensure PCB layout compatibility without redesign.
• Output Configuration: All substitutes maintain low-side N-Channel switching topology with 1:1 input-to-output ratio and non-inverting input logic.
• Electrical Headroom: Substitute parts must support the maximum load voltage of 35V or higher. All qualified substitutes operate at 36V or 55V maximum load voltage, providing adequate margin.
• Current Capability: The IPS031S output current of 2.8A is the minimum requirement. All substitute parts exceed this specification (12A to 30A), ensuring functional compatibility with existing circuit designs.
• Fault Protection: All substitutes include current limiting and over-temperature protection, matching the IPS031S protection scheme. Enhanced substitutes add over-voltage protection.
• Operating Temperature Range: The IPS031S operates from -40°C to 150°C. Substitutes with specified temperature ranges match or exceed this specification.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are manufactured by STMicroelectronics and carry active product status, ensuring long-term availability and supply chain continuity. Each substitute is ROHS3 compliant, addressing environmental and regulatory requirements that the obsolete IPS031S does not meet.

VNB14NV04TR-E and VNB35NV04TR-E are recommended as primary substitutes for applications requiring the -40°C to 150°C operating temperature range specified in the IPS031S. Both parts are OMNIFET II series devices with specified temperature ranges matching the original part.

VNB35NV04TR-E provides the highest performance margin with 30A output current capability and 13mOhm on-resistance, suitable for designs requiring enhanced thermal performance and lower power dissipation.

VNB14NV04TR-E offers a balanced approach with 12A output current and 35mOhm on-resistance, maintaining compatibility with the original 35V load voltage specification while providing active product status and full temperature range specification.

For applications where operating temperature range is not critical, VNB10N07TR-E, VNB20N07TR-E, and VNB35N07TR-E are functionally compatible alternatives with higher load voltage ratings (55V) and enhanced fault protection including over-voltage detection.

Frequently Asked Questions (FAQ)

Q: Can the IPS031S be directly replaced with any of these substitute parts without PCB modification?

A: Yes. All substitute parts use the identical D2PAK (TO-263-3) surface-mount package with the same pinout configuration (2 leads plus tab), enabling direct PCB replacement without layout changes.

Q: What is the primary reason for substituting the IPS031S?

A: The IPS031S is classified as obsolete. All substitute parts carry active product status, ensuring continued availability, manufacturing support, and compliance with current environmental regulations (ROHS3).

Q: Are the substitute parts electrically compatible with the IPS031S circuit design?

A: Yes. All substitutes maintain the same low-side N-Channel switching topology, 1:1 input-to-output ratio, non-inverting input logic, and fault protection scheme. All substitute parts support the 35V maximum load voltage and exceed the 2.8A output current requirement.

Q: Which substitute part should be selected for temperature-critical applications?

A: VNB14NV04TR-E and VNB35NV04TR-E both specify the -40°C to 150°C operating temperature range, matching the IPS031S specification. VNB35NV04TR-E provides superior thermal performance with lower on-resistance.

Q: What is the difference between OMNIFET and OMNIFET II series substitutes?

A: Both series are STMicroelectronics VIPower N-Channel power switches. OMNIFET II devices (VNB14NV04TR-E and VNB35NV04TR-E) include specified operating temperature ranges and represent enhanced product generations with improved performance characteristics.

Q: Do all substitute parts include over-voltage protection?

A: All five substitute parts include over-voltage protection in addition to current limiting and over-temperature protection. The IPS031S includes only current limiting and over-temperature protection, making the substitutes functionally superior in fault protection capability.

Q: What is the moisture sensitivity level (MSL) difference between the IPS031S and substitutes?

A: The IPS031S carries MSL 1 (unlimited shelf life). All STMicroelectronics substitutes carry MSL 3 (168 hours), requiring standard moisture control during storage and handling per IPC-A-610 standards.
