IPS1031SPBF Equivalent & Substitute Parts

Part Overview

The IPS1031SPBF is a Power Switch/Driver IC manufactured by Infineon Technologies, classified as a general-purpose N-Channel low-side switch with 1:1 input-output ratio in D2PAK packaging. The device is rated for 3.3A maximum output current and 28V maximum load voltage, with 40mOhm typical on-resistance and integrated current limiting and over-temperature protection.

The IPS1031SPBF has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this power switch topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IPS1031SPBF are selected based on the following critical parameters that define functional equivalence:

• Package Compatibility: All substitutes maintain TO-263-3 D2PAK form factor for direct PCB footprint compatibility
• Topology: All substitutes are general-purpose N-Channel low-side switches with 1:1 input-output ratio and non-inverting interface
• Fault Protection: All substitutes include current limiting and over-temperature protection as minimum requirements
• Mounting Type: All substitutes are surface-mount devices

The substitute parts are grouped into two categories based on voltage and current ratings:

Group 1 (36V Maximum Load Voltage): VNB14NV04TR-E and VNB35NV04TR-E provide higher current capacity (12A and 30A respectively) while maintaining the same maximum load voltage as the original part's application envelope.

Group 2 (55V Maximum Load Voltage): VNB10N07TR-E, VNB20N07TR-E, and VNB35N07TR-E support higher load voltages (55V) with current ratings ranging from 14A to 25A, suitable for applications requiring extended voltage headroom.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by STMicroelectronics and maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete IPS1031SPBF.

For applications with load voltages up to 36V: VNB14NV04TR-E and VNB35NV04TR-E are suitable selections. Both devices specify operating temperature range of -40°C to 150°C (TJ), matching the original part's thermal specification. VNB35NV04TR-E provides significantly higher current capacity (30A) and lower on-resistance (13mOhm max) for improved thermal performance in power-limited designs.

For applications with load voltages up to 55V: VNB10N07TR-E, VNB20N07TR-E, and VNB35N07TR-E accommodate extended voltage headroom. VNB35N07TR-E offers the highest current rating (25A) and lowest on-resistance (28mOhm max) within this voltage class. All three devices include over-voltage protection in addition to current limiting and over-temperature protection.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Moisture sensitivity level (MSL) for all STMicroelectronics substitutes is rated at 3 (168 Hours), compared to MSL 1 for the original part; storage and handling procedures should reflect this specification.

Frequently Asked Questions (FAQ)

Q: Can VNB35NV04TR-E directly replace IPS1031SPBF on existing PCBs?

A: Yes. VNB35NV04TR-E maintains identical TO-263-3 D2PAK packaging and pinout. The device is a direct footprint replacement. Verify that your application's load voltage does not exceed 36V and that the 30A current rating is appropriate for your circuit.

Q: What is the difference between VNB35N07TR-E and VNB35NV04TR-E?

A: Both are 25A/30A N-Channel low-side switches in D2PAK packaging. VNB35N07TR-E supports 55V maximum load voltage with 28mOhm on-resistance. VNB35NV04TR-E supports 36V maximum load voltage with 13mOhm on-resistance. Select based on your application's voltage requirements and thermal constraints.

Q: Are all substitute parts surface-mount compatible with the original design?

A: Yes. All substitute parts use surface-mount D2PAK packaging identical to the IPS1031SPBF. No PCB layout modifications are required.

Q: Do the substitute parts include the same fault protection as the original?

A: All substitute parts include current limiting and over-temperature protection. Additionally, all STMicroelectronics substitutes include over-voltage protection, providing enhanced circuit protection compared to the original IPS1031SPBF.

Q: What is the moisture sensitivity level (MSL) for substitute parts?

A: All STMicroelectronics substitute parts are rated MSL 3 (168 Hours), compared to MSL 1 (Unlimited) for the original part. Ensure proper storage conditions and follow manufacturer handling guidelines for moisture-sensitive devices.

Q: Which substitute part should I select for a new design?

A: Selection depends on your application's maximum load voltage and required output current. For voltages up to 36V, VNB35NV04TR-E provides the lowest on-resistance (13mOhm) and highest current capacity (30A). For voltages up to 55V, VNB35N07TR-E offers 25A capacity with 28mOhm on-resistance. Both devices specify -40°C to 150°C operating temperature range.
