IPS031STRR Equivalent & Substitute Parts

Part Overview

The IPS031STRR is a Power Management IC (PMIC) manufactured by Infineon Technologies, classified as a Power Switch/Driver with 1:1 N-Channel configuration and 2.8A maximum output current in D2PAK packaging. This component is designed for low-side switching applications with on/off interface control and integrated current limiting and over-temperature protection.

The IPS031STRR has reached obsolete product status. Identifying qualified substitute components ensures design continuity and maintains supply chain reliability for applications requiring equivalent switching performance and thermal management characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IPS031STRR is determined by the following critical electrical and mechanical parameters:

• Output Configuration: Low-side N-channel switching with 1:1 ratio
• Current Rating: Maximum output current must meet or exceed 2.8A
• Voltage Rating: Load voltage capability must support 35V maximum
• On-Resistance: Rds On characteristics affect thermal performance and power dissipation
• Fault Protection: Current limiting and over-temperature protection required
• Package Compatibility: Surface mount DPAK/D2PAK family packages with equivalent pinout
• Operating Temperature Range: -40°C to 150°C junction temperature capability
• Interface Type: On/off control with non-inverting input

The VND3NV04TR-E from STMicroelectronics meets these substitution criteria with equivalent functional architecture and enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The VND3NV04TR-E qualifies as a functional substitute for the IPS031STRR based on the following engineering criteria:

Electrical Compatibility: The substitute part exceeds the current rating (4.6A vs. 2.8A) and voltage rating (36V vs. 35V) of the original component, ensuring adequate performance margin in low-side switching applications. Both devices maintain identical operating temperature ranges and non-inverting input interface architecture.

Fault Protection Enhancement: The VND3NV04TR-E incorporates additional over-voltage protection beyond the current limiting and over-temperature features of the IPS031STRR, providing enhanced circuit protection.

Product Status and Compliance: The VND3NV04TR-E maintains active product status with ROHS3 compliance, addressing regulatory requirements for new designs. The IPS031STRR's obsolete status and RoHS non-compliance status necessitate transition to qualified alternatives.

Package Consideration: Both components use compatible surface-mount DPAK/D2PAK packages with equivalent pinout configurations (2 leads + tab). PCB layout modifications are not required for substitution.

Supply Availability: The VND3NV04TR-E demonstrates significantly higher inventory availability (27,700 pcs) compared to the IPS031STRR (894 pcs), supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the VND3NV04TR-E directly replace the IPS031STRR without PCB modifications?

A: Yes. Both components use equivalent DPAK/D2PAK surface-mount packages with identical pinout configuration (2 leads + tab). No PCB layout changes are required for substitution.

Q: What is the impact of the higher Rds On value in the VND3NV04TR-E?

A: The VND3NV04TR-E specifies 120mOhm maximum Rds On compared to 45mOhm typical for the IPS031STRR. This results in increased on-state power dissipation. Thermal analysis of the specific application circuit is required to confirm acceptable junction temperature operation within the -40°C to 150°C range.

Q: Are the voltage and current ratings of the VND3NV04TR-E sufficient for IPS031STRR applications?

A: Yes. The substitute part exceeds both specifications: 4.6A output current (vs. 2.8A required) and 36V load voltage (vs. 35V required). These margins ensure adequate performance in equivalent switching applications.

Q: What is the significance of the additional over-voltage protection in the VND3NV04TR-E?

A: The VND3NV04TR-E includes integrated over-voltage protection in addition to current limiting and over-temperature protection. This provides enhanced fault tolerance but does not affect functional compatibility with IPS031STRR circuit designs.

Q: Does the ROHS3 compliance of the VND3NV04TR-E affect compatibility?

A: No. ROHS3 compliance indicates enhanced environmental and regulatory alignment. The RoHS non-compliant status of the IPS031STRR does not prevent functional substitution, but ROHS3 compliance of the alternative supports regulatory requirements for new production designs.

Q: Are there any interface or control signal differences between these components?

A: No. Both components use identical non-inverting on/off interface control. Signal timing and logic levels are compatible without modification.
