Output Configuration: All substitutes maintain Low Side N-Channel output configuration with 1:1 input:output ratio and On/Off interface
Input Type: All substitutes use Non-Inverting input type, preserving control signal logic
Fault Protection: All substitutes include Current Limiting (Fixed) and Over Temperature protection; enhanced substitutes add Over Voltage protection
Load Voltage Rating: Substitute parts are rated for 36V or 55V maximum load voltage, exceeding the original 28V specification
Current Rating: Substitute parts range from 12A to 30A output current, all exceeding the original 3.3A specification
Operating Temperature: Substitutes with specified temperature ranges maintain -40°C ~ 150°C (TJ) compatibility

All five substitute parts meet or exceed the electrical and mechanical requirements of the IPS1031STRRPBF within the D2PAK package constraint.

Engineering Selection Recommendations

All five substitute parts are active products with ROHS3 compliance and REACH unaffected status, providing regulatory continuity for new designs. Selection should be based on application-specific current and voltage requirements:

VNB14NV04TR-E and VNB35NV04TR-E are OMNIFET II™ series devices with specified operating temperature ranges of -40°C ~ 150°C (TJ), matching the original IPS1031STRRPBF thermal specification. VNB35NV04TR-E provides the lowest on-resistance (13mOhm Max) and highest current rating (30A), suitable for applications requiring minimal power dissipation. VNB14NV04TR-E offers 12A current capacity with 35mOhm on-resistance at a 36V load voltage rating.

VNB10N07TR-E, VNB20N07TR-E, and VNB35N07TR-E are OMNIFET™ series devices with 55V load voltage ratings and enhanced over-voltage protection. VNB20N07TR-E and VNB35N07TR-E include Status Flag functionality. Operating temperature ranges are not specified for these variants.

For applications requiring thermal specification matching and lowest on-resistance, VNB35NV04TR-E is the optimal substitute. For applications with 55V load voltage requirements, VNB35N07TR-E provides the best performance within the OMNIFET™ series.

Frequently Asked Questions (FAQ)

Q: Can IPS1031STRRPBF be directly replaced with any of these substitutes?

A: Yes. All substitute parts share identical D2PAK package geometry, Low Side N-Channel output configuration, 1:1 input:output ratio, and On/Off control interface. Direct PCB footprint compatibility is maintained. Electrical performance exceeds the original specification across all parameters.

Q: What is the primary reason for substitution?

A: The IPS1031STRRPBF is obsolete. All five substitute parts are active products from STMicroelectronics with current manufacturing status and full regulatory compliance (ROHS3, REACH unaffected).

Q: How do the current ratings differ?

A: The original IPS1031STRRPBF is rated for 3.3A maximum output current. Substitutes range from 12A (VNB14NV04TR-E) to 30A (VNB35NV04TR-E). Applications operating below 3.3A can use any substitute without derating. Applications requiring higher current capacity should select VNB35N07TR-E (25A) or VNB35NV04TR-E (30A).

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

A: OMNIFET II™ variants (VNB14NV04TR-E, VNB35NV04TR-E) include specified operating temperature ranges of -40°C ~ 150°C (TJ), matching the original device. OMNIFET™ variants (VNB10N07TR-E, VNB20N07TR-E, VNB35N07TR-E) do not specify operating temperature ranges but offer 55V load voltage ratings and enhanced over-voltage protection.

Q: Which substitute has the lowest on-resistance?

A: VNB35NV04TR-E has the lowest on-resistance at 13mOhm (Max), compared to the original 40mOhm specification. This reduces power dissipation and heat generation in switching applications.

Q: Are all substitutes RoHS compliant?

A: Yes. All five substitute parts are ROHS3 compliant. The original IPS1031STRRPBF RoHS status is not specified.

Q: What is the moisture sensitivity difference?

A: The original IPS1031STRRPBF has MSL 1 (Unlimited). All substitute parts have MSL 3 (168 Hours), requiring standard moisture control during storage and handling per IPC-A-610 standards.

Q: Can I use VNB35NV04TR-E in a 55V application?

A: No. VNB35NV04TR-E is rated for 36V maximum load voltage. For 55V applications, use VNB10N07TR-E, VNB20N07TR-E, or VNB35N07TR-E.
