TPS2053DR Equivalent & Substitute Parts

Part Overview

The TPS2053DR is a Power Management Integrated Circuit (PMIC) manufactured by Texas Instruments, classified as a Power Switch/Driver with 1:1 N-Channel configuration. This 16-SOIC surface mount device provides high-side switching capability with 500mA maximum output current and integrated fault protection including current limiting, over-temperature, and under-voltage lockout (UVLO) functions.

The TPS2053DR is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this power switching topology.

Substitute Part Grouping Explanation

Substitute parts for the TPS2053DR are identified based on strict parametric equivalence within the following critical parameters:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Switch Type: General Purpose
• Output Configuration: High Side
• Output Type: N-Channel
• Number of Outputs: 3
• Ratio - Input:Output: 1:1
• Voltage - Load: 2.7V ~ 5.5V
• Current - Output (Max): 500mA
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO
• Operating Temperature: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories:

Parametric Equivalents (Active Status): Parts that maintain all critical electrical and mechanical parameters with variations only in Rds On (Typ) and Input Type characteristics. These parts are currently in active production status.

Direct Manufacturer Variants (Discontinued Status): Parts that share identical base product numbers and electrical specifications but differ in packaging designation or product lifecycle status.

Engineering Selection Recommendations

Primary Substitutes (Active Production Status):

TPS2053BDR and TPS2043DR are recommended as primary substitutes for the obsolete TPS2053DR. Both parts maintain active product status with current manufacturing availability. TPS2053BDR shares identical input type (Non-Inverting) with the original TPS2053DR and offers improved Rds On performance (70mOhm vs. 80mOhm). TPS2043DR maintains the same Rds On specification (80mOhm) as the original part but features Inverting input type, requiring circuit-level design consideration.

TPS2043BDR combines active product status with improved Rds On performance (70mOhm) but implements Inverting input type, necessitating input signal inversion in the application circuit.

Secondary Substitute (Limited Availability):

TPS2053D is listed as discontinued at DiGi Electronics and represents a direct manufacturer variant of the TPS2053DR. This part maintains identical electrical specifications and Non-Inverting input type but offers only limited remaining inventory (1,061 pieces). This option is suitable only for applications with immediate, short-term requirements where inventory depletion is acceptable.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical fault protection architecture, ensuring regulatory and environmental compatibility with the original TPS2053DR specification.

Frequently Asked Questions (FAQ)

Q: Can TPS2043DR be used as a direct replacement for TPS2053DR?

A: TPS2043DR is parametrically equivalent to TPS2053DR in all critical electrical and mechanical specifications. However, TPS2043DR implements Inverting input type while TPS2053DR uses Non-Inverting input type. Direct PCB substitution without circuit modification is not possible. Input signal inversion must be implemented in the application circuit, or an alternative part with matching input type must be selected.

Q: What is the difference between TPS2053BDR and TPS2043BDR?

A: Both parts are active production substitutes with identical electrical specifications except for input type. TPS2053BDR uses Non-Inverting input logic, while TPS2043BDR uses Inverting input logic. TPS2053BDR is the preferred substitute for TPS2053DR applications requiring no circuit modification. TPS2043BDR requires input signal inversion implementation.

Q: Why does TPS2053BDR show lower Rds On (70mOhm) compared to TPS2053DR (80mOhm)?

A: The Rds On specification difference reflects manufacturing process improvements in the active production variant. Lower Rds On reduces on-state power dissipation and heat generation, providing improved thermal performance. This represents a beneficial parameter variation and does not affect functional compatibility.

Q: Is TPS2053D a viable substitute option?

A: TPS2053D maintains identical specifications to TPS2053DR and shares the same Non-Inverting input type. However, this part is discontinued at DiGi Electronics with limited remaining inventory (1,061 pieces). This option is suitable only for immediate, short-term production requirements where inventory depletion within the project timeline is acceptable. For ongoing or future production, TPS2053BDR is the recommended substitute.

Q: Are all substitute parts available in the same 16-SOIC package?

A: All substitute parts are manufactured in the 16-SOIC (0.154", 3.90mm Width) package, ensuring mechanical and electrical compatibility with existing PCB designs. No package-level modifications are required for physical substitution.

Q: Do all substitute parts maintain the same fault protection features?

A: All substitute parts implement identical fault protection architecture: Current Limiting (Fixed), Over Temperature, and Under-Voltage Lockout (UVLO). Functional protection capability is maintained across all substitute options.

Q: What is the inventory status for substitute parts?

A: TPS2053BDR has 3,913 pieces in stock, TPS2043DR has 3,800 pieces in stock, and TPS2043BDR has 3,076 pieces in stock. All three active production parts maintain adequate inventory levels for production planning. TPS2053D has 1,061 pieces remaining and is discontinued at DiGi Electronics.
