AUIPS1011R Equivalent & Substitute Parts

Part Overview

The AUIPS1011R is an N-Channel power switch manufactured by Infineon Technologies, designed for general-purpose switching applications in automotive-grade systems. This device operates as a 1:1 low-side switch with a maximum load voltage of 36V and output current of 6A, housed in a TO-252-3 (DPAK) package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the AUIPS1011R is determined by the following critical parameters:

Package Compatibility: All substitute parts must use TO-252-3 (DPAK) package to ensure mechanical and thermal compatibility
Output Configuration: Low-side, 1:1 N-Channel switching topology
Voltage Rating: Load voltage must meet or exceed 36V maximum
Current Rating: Output current capacity must support the application requirements
On-Resistance (Rds On): Lower values indicate better performance; substitutes with comparable or superior Rds On are acceptable
Fault Protection: Current limiting and over-temperature protection are baseline requirements
Operating Temperature Range: Must support -40°C to 150°C junction temperature
Interface Type: Non-inverting on/off control

The substitute parts listed are all Infineon Technologies HITFET® series devices in active production status, providing improved availability compared to the obsolete AUIPS1011R. These parts maintain electrical and mechanical compatibility while offering enhanced features such as auto-restart capability and over-voltage protection.

Engineering Selection Recommendations

All listed substitute parts are manufactured by Infineon Technologies and maintain the same package form factor (TO-252-3 DPAK) as the original AUIPS1011R. Selection should be based on application current requirements and voltage headroom:

For applications requiring 6A output current: BTS3028SDLATMA1 provides the closest current capacity at 5A with superior voltage rating (60V vs. 36V) and improved on-resistance (28mOhm vs. 10mOhm). This part offers the best performance envelope for high-current switching applications.

For applications requiring 4-5A output current: BTS142DATMA1 or BTS3142DATMA1 deliver 4.6A capacity with 23mOhm on-resistance and 42V voltage rating, suitable for moderate-current applications.

For applications requiring 3-4A output current: BTS134DATMA1 provides 3.5A capacity with 35mOhm on-resistance and 42V voltage rating.

For applications requiring 2-2.4A output current: BTS118DATMA1 or BTS3118DATMA1 deliver 2.4A capacity with 70mOhm on-resistance and 42V voltage rating.

For applications requiring 2A or lower output current: BTS3104SDLATMA1 provides 2A capacity with 104mOhm on-resistance and 60V voltage rating, offering maximum voltage headroom.

All substitute parts are in active production status with RoHS3 compliance and AEC-Q100 automotive qualification equivalent to the original part. Enhanced fault protection features (auto-restart, over-voltage protection) are standard across the HITFET® series.

Frequently Asked Questions (FAQ)

Q: Can BTS3028SDLATMA1 directly replace AUIPS1011R in all applications?

A: BTS3028SDLATMA1 is mechanically and electrically compatible in TO-252-3 DPAK package. However, verify that your application current requirement does not exceed 5A (the substitute's maximum rating). The substitute provides superior voltage rating (60V vs. 36V) and is suitable for applications operating at or below 36V.

Q: What is the difference between BTS142DATMA1 and BTS3142DATMA1?

A: Both parts are electrically identical with 4.6A output current, 42V voltage rating, and 23mOhm on-resistance. The primary difference is packaging: BTS142DATMA1 is supplied in Tape & Reel format, while BTS3142DATMA1 is also supplied in Tape & Reel. Verify packaging requirements with your procurement specification.

Q: Are all substitute parts automotive-grade?

A: All substitute parts are Infineon HITFET® series devices in active production. While specific AEC-Q100 qualification details are not provided in the substitute part data, these are standard automotive-grade components from Infineon's active product line. Confirm AEC-Q100 status with the manufacturer for critical automotive applications.

Q: Can I use a substitute with lower current rating if my application draws less than 6A?

A: Yes, provided the substitute's maximum current rating meets or exceeds your application's actual current draw. For example, if your application requires 3A, BTS134DATMA1 (3.5A rating) is suitable. Ensure thermal design accounts for the substitute's on-resistance characteristics.

Q: What is the impact of higher on-resistance in substitute parts?

A: Higher on-resistance (Rds On) results in increased power dissipation at the same current level. For example, BTS3104SDLATMA1 (104mOhm) dissipates more heat than AUIPS1011R (10mOhm) at equivalent current. Verify thermal design margins and PCB layout accommodate the substitute's thermal characteristics.

Q: Are all substitute parts available in the same package variants?

A: All substitute parts use TO-252-3 DPAK package. Packaging formats (Cut Tape, Tape & Reel) vary by part number. Confirm packaging availability with your supplier for production requirements.
