IPS021S Equivalent & Substitute Parts

Part Overview

The IPS021S 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 1.8A in a D2PAK surface-mount package. The IPS021S is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility through equivalent electrical parameters and identical packaging specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IPS021S are selected based on strict electrical and mechanical compatibility criteria. All substitute parts must meet the following requirements:

Critical Compatibility Parameters:

• Output Configuration: Low Side
• Output Type: N-Channel
• Ratio - Input:Output: 1:1
• Interface: On/Off
• Input Type: Non-Inverting
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount

Electrical Performance Criteria:

• Voltage - Load (Max): Must equal or exceed 35V
• Current - Output (Max): Must equal or exceed 1.8A
• Rds On (Typ): Lower values indicate improved performance but are not limiting factors

All identified substitute parts are manufactured by STMicroelectronics and maintain active product status, ensuring long-term availability and supply chain reliability compared to the obsolete IPS021S.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by STMicroelectronics and maintain active product status, ensuring availability and supply chain continuity. The following factors should guide component selection:

Compliance Considerations: All substitute parts are ROHS3 compliant, whereas the IPS021S is RoHS non-compliant. This compliance improvement is significant for applications subject to environmental regulations.

Product Status: The IPS021S is obsolete. All substitute parts are active products with ongoing manufacturer support and availability.

Electrical Margin: All substitute parts exceed the IPS021S electrical specifications. VNB10N07TR-E, VNB20N07TR-E, and VNB35N07TR-E support 55V maximum load voltage compared to the IPS021S 35V rating. VNB14NV04TR-E and VNB35NV04TR-E support 36V maximum load voltage. All parts support current output exceeding the 1.8A requirement.

Temperature Rating: VNB14NV04TR-E and VNB35NV04TR-E specify operating temperature range of -40°C to 150°C (TJ), matching the IPS021S specification. VNB10N07TR-E, VNB20N07TR-E, and VNB35N07TR-E do not specify operating temperature range in provided data.

Enhanced Protection: All substitute parts include over-voltage fault protection in addition to current limiting and over-temperature protection provided by the IPS021S.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts directly replace the IPS021S without circuit modification?

A: All listed substitute parts maintain identical package specifications (TO-263-3, D2PAK) and functional configuration (1:1 low-side N-Channel switch). Pin-to-pin compatibility is maintained. However, circuit validation is required to confirm that enhanced electrical specifications do not introduce unintended behavior in the application.

Q: What is the primary reason the IPS021S requires substitution?

A: The IPS021S is classified as obsolete. Substitute parts are active products with guaranteed long-term availability and manufacturer support.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, whereas the IPS021S is RoHS non-compliant. This is a significant compliance improvement for new designs.

Q: Do substitute parts provide additional protection features?

A: Yes. All substitute parts include over-voltage fault protection in addition to the current limiting and over-temperature protection provided by the IPS021S.

Q: Which substitute part most closely matches the IPS021S electrical specifications?

A: VNB14NV04TR-E and VNB35NV04TR-E both specify operating temperature range of -40°C to 150°C (TJ), matching the IPS021S. VNB14NV04TR-E provides 12A output current and VNB35NV04TR-E provides 30A output current, both exceeding the 1.8A IPS021S specification.

Q: Are there package differences between the IPS021S and substitute parts?

A: All parts use identical D2PAK (TO-263-3) surface-mount packaging. No PCB layout modifications are required for package compatibility.

Q: What is the significance of lower Rds On values in substitute parts?

A: Lower Rds On (on-state resistance) values indicate reduced power dissipation during switching operation. All substitute parts provide improved thermal performance compared to the IPS021S 130mOhm specification.
