Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2811D is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side only
• Number of Drivers: 2 channels
• Gate Type: N-Channel MOSFET
• Voltage - Supply: 4V ~ 14V range
• Logic Voltage Thresholds: VIL = 1V, VIH = 4V
• Current - Peak Output: 2A source and 2A sink capability
• Input Type: Inverting logic
• Rise / Fall Time: 14ns rise, 15ns fall (typical)
• Operating Temperature Range: -40°C ~ 125°C
• Package / Case: 8-SOIC form factor
• Mounting Type: Surface Mount

The TPS2811DR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The TPS2811DR is the direct equivalent substitute for the TPS2811D. Both parts share identical electrical characteristics, thermal specifications, and package geometry. The TPS2811DR maintains Active product status, ensuring continued availability and long-term supply chain stability compared to the Last Time Buy status of the TPS2811D.

Both parts comply with ROHS3 and REACH requirements, making them suitable for applications subject to environmental and regulatory compliance standards. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing.

Selection between these parts should be based on packaging requirements and procurement strategy. The TPS2811DR in Cut Tape & Digi-Reel format is recommended for high-volume production and automated assembly processes. The TPS2811D in Tube packaging may be retained for existing inventory management or lower-volume applications where tube format is preferred.

Frequently Asked Questions (FAQ)

Q: Can the TPS2811DR directly replace the TPS2811D in existing designs?

A: Yes. The TPS2811DR is electrically and mechanically identical to the TPS2811D. Both devices feature the same 8-SOIC package, identical pin configuration, and equivalent electrical performance across all specified parameters. No circuit modifications are required.

Q: What is the difference between TPS2811D and TPS2811DR?

A: The primary differences are product status and packaging format. The TPS2811D is Last Time Buy (end-of-life) supplied in Tube packaging. The TPS2811DR is Active (ongoing production) supplied in Cut Tape & Digi-Reel format. Electrical specifications and package dimensions are identical.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the same temperature range (-40°C to 125°C) and share identical thermal characteristics. Moisture sensitivity level (MSL 1) is equivalent for both variants.

Q: Which packaging format should I specify for new designs?

A: The TPS2811DR in Cut Tape & Digi-Reel format is recommended for new designs due to Active product status and suitability for automated assembly. This ensures long-term supply availability and compatibility with modern manufacturing processes.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the TPS2811D and TPS2811DR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Can I mix TPS2811D and TPS2811DR in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same assembly. However, for traceability and supply chain consistency, using a single part number per production run is recommended.
