TPS2011DR Equivalent & Substitute Parts

Part Overview

The TPS2011DR is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 1:1 N-Channel configuration. This component is classified as a general-purpose high-side N-channel switch rated for 600mA output current in an 8-SOIC surface mount package. The TPS2011DR is designated as "Not For New Designs," indicating it has reached end-of-life status. For new applications and ongoing production requirements, identifying functionally equivalent alternatives is essential to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2011DR is determined by strict alignment with the following critical parameters:

• Package Compatibility: 8-SOIC surface mount package with identical pinout and mechanical dimensions (0.154", 3.90mm Width)
• Electrical Specifications: 1:1 input-to-output ratio, high-side N-channel output configuration, non-inverting input interface
• Load Voltage Range: 2.7V ~ 5.5V operating range
• Current Rating: 600mA maximum output current
• Thermal Performance: -40°C ~ 125°C operating temperature range
• Protection Features: Current limiting and over-temperature fault protection as minimum requirements
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The TPS2011ADR meets all substitution criteria as a direct equivalent from the same manufacturer within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The TPS2011ADR is the direct substitute for the TPS2011DR. Both components share identical package geometry, electrical specifications, and operating parameters. The TPS2011ADR carries Active product status, ensuring long-term availability and supply chain support, whereas the TPS2011DR is designated Not For New Designs. The TPS2011ADR incorporates an additional UVLO (Under-Voltage Lock-Out) protection feature and demonstrates improved on-resistance performance (33mOhm versus 75mOhm), providing enhanced thermal efficiency and fault protection. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. For applications currently using TPS2011DR, migration to TPS2011ADR is supported without circuit redesign due to pin-compatible 8-SOIC packaging and functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can TPS2011ADR be used as a direct replacement for TPS2011DR in existing designs?

A: Yes. The TPS2011ADR is pin-compatible and functionally equivalent. Both components use the 8-SOIC package with identical pinout, operate across the same 2.7V to 5.5V load voltage range, and deliver 600mA maximum output current. No circuit modifications are required for substitution.

Q: What is the difference in on-resistance between these parts?

A: The TPS2011DR has a typical on-resistance of 75mOhm, while the TPS2011ADR has 33mOhm. The lower on-resistance of the TPS2011ADR results in reduced power dissipation and improved thermal performance under load.

Q: Why is TPS2011DR marked as "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. Texas Instruments recommends using the TPS2011ADR for new applications to ensure long-term supply availability and access to current manufacturing processes.

Q: Are there any protection feature differences?

A: The TPS2011ADR includes UVLO (Under-Voltage Lock-Out) protection in addition to the current limiting and over-temperature protection found in both parts. UVLO prevents device operation during low supply voltage conditions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TPS2011DR and TPS2011ADR are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: What is the package footprint for these components?

A: Both parts use an 8-SOIC surface mount package measuring 0.154 inches (3.90mm) in width. The identical package dimensions ensure mechanical compatibility in PCB layouts.
