Substitute Part Grouping Explanation

Substitution of the AUIPS6021STRL is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Output Type: N-Channel (must match)
• Ratio - Input:Output: 1:1 (must match)
• Output Configuration: High Side (must match)
• Interface: On/Off (must match)
• Input Type: Non-Inverting (must match)
• Switch Type: General Purpose (must match)
• Number of Outputs: 1 (must match)
• Voltage - Load: Maximum rating must equal or exceed 36V
• Current - Output (Max): Must equal or exceed 4.3A
• Operating Temperature Range: Must encompass -40°C ~ 150°C (TJ)

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount (must match)
• Package compatibility: Pin configuration and lead count must support direct or adapter-based substitution

Compliance & Certification:

• Fault Protection features must include at minimum: Current Limiting (Fixed), Open Load Detect, Over Temperature
• Automotive Grade and AEC-Q100 qualification are preferred for applications requiring these standards

The VN750B5TR-E meets all electrical and mechanical substitution criteria while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The VN750B5TR-E is the manufacturer-recommended substitute for the AUIPS6021STRL based on the following engineering criteria:

Functional Equivalence: All critical electrical parameters align: N-Channel output type, 1:1 ratio, High Side configuration, On/Off interface, and Non-Inverting input. The VN750B5TR-E exceeds the current requirement (6A vs. 4.3A) and maintains the same operating temperature range (-40°C ~ 150°C TJ).

Active Product Status: The VN750B5TR-E is classified as Active, ensuring ongoing availability, manufacturing support, and technical documentation. The AUIPS6021STRL is Obsolete, making substitution necessary for new designs and long-term supply chain continuity.

Enhanced Protection Features: The VN750B5TR-E includes Over Voltage fault protection in addition to the Current Limiting (Fixed), Open Load Detect, and Over Temperature protection present in the AUIPS6021STRL. A Status Flag feature is also included.

Compliance & Certification: The VN750B5TR-E is ROHS3 Compliant and REACH Unaffected. Both devices share EAR99 ECCN classification and identical HTSUS codes.

Package Consideration: The AUIPS6021STRL uses D2PAK (TO-263-5) packaging, while the VN750B5TR-E uses P2PAK packaging. Both are 4-lead + tab surface mount packages. PCB layout verification is required to confirm pin-compatible placement.

On-Resistance Trade-off: The VN750B5TR-E exhibits higher typical on-resistance (60mOhm Max vs. 24mOhm Typ for AUIPS6021STRL). Thermal analysis of the application circuit is recommended to confirm acceptable power dissipation at maximum load conditions.

Frequently Asked Questions (FAQ)

Q: Can the VN750B5TR-E directly replace the AUIPS6021STRL without circuit modifications?

A: Electrical substitution is direct based on matching output type, configuration, interface, and protection features. However, package differences (D2PAK vs. P2PAK) require PCB layout verification. The higher on-resistance of the VN750B5TR-E may affect thermal performance; thermal analysis of your specific application is necessary.

Q: What is the significance of the higher on-resistance in the VN750B5TR-E?

A: The VN750B5TR-E has a maximum on-resistance of 60mOhm compared to the AUIPS6021STRL's typical 24mOhm. This results in increased power dissipation at maximum current (4.3A). Calculate power loss (P = I²R) for your operating conditions to confirm thermal margins remain acceptable.

Q: Are there any compatibility issues with the packaging change from D2PAK to P2PAK?

A: Both packages are 4-lead + tab surface mount configurations with similar footprints. Pin assignment and lead spacing must be verified against your PCB design. Consult the respective datasheets for exact dimensional specifications and pinout diagrams before layout finalization.

Q: Does the VN750B5TR-E include all protection features of the AUIPS6021STRL?

A: Yes. The VN750B5TR-E includes Current Limiting (Fixed), Open Load Detect, and Over Temperature protection matching the AUIPS6021STRL. Additionally, it provides Over Voltage protection and a Status Flag output not present in the original device.

Q: What is the moisture sensitivity difference between these parts?

A: The AUIPS6021STRL has MSL 1 (Unlimited), while the VN750B5TR-E has MSL 3 (168 Hours). MSL 3 requires controlled storage and handling conditions. Verify your supply chain and storage procedures can accommodate the stricter moisture sensitivity requirements.

Q: Is the VN750B5TR-E suitable for automotive applications?

A: The VN750B5TR-E is not explicitly marked with Automotive Grade or AEC-Q100 qualification in the provided specifications. The AUIPS6021STRL carries both certifications. If your application requires automotive qualification, confirm with STMicroelectronics whether the VN750B5TR-E meets your specific automotive standards.

Q: What is the availability status of both parts?

A: The AUIPS6021STRL is Obsolete with 1166 pcs in stock. The VN750B5TR-E is Active with 2400 pcs in stock, ensuring long-term procurement availability and manufacturing continuity.
