TPS2047DR Equivalent & Substitute Parts

Part Overview

The TPS2047DR is a Power Management Integrated Circuit (PMIC) manufactured by Texas Instruments, classified as a Power Switch/Driver with N-Channel output configuration. This component operates as a general-purpose high-side switch with 1:1 input-to-output ratio and 250mA maximum output current capability. The TPS2047DR is currently listed as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2047DR is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Package / Case: 16-SOIC form factor (physical and electrical compatibility)
• Output Type: N-Channel configuration
• Output Configuration: High Side switching topology
• Number of Outputs: 3 outputs
• Voltage - Load: 2.7V ~ 5.5V operating range
• Current - Output (Max): 250mA capability
• Rds On (Typ): 80mOhm on-resistance
• Operating Temperature: -40°C ~ 85°C range
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO

Identified Substitute:

The TPS2057DR qualifies as a parametric equivalent. While the TPS2057DR features a 1:2, 1:1 input-to-output ratio (compared to the TPS2047DR's 1:1 ratio) and non-inverting input type (compared to inverting), all critical electrical and mechanical parameters remain aligned. The TPS2057DR maintains identical package, output configuration, current rating, voltage specifications, thermal protection, and compliance certifications. The TPS2057DR is currently in active product status, providing design continuity for obsolete TPS2047DR applications.

The TPS2047D is listed as a direct manufacturer part number variant but is discontinued at DiGi Electronics. This part shares identical electrical specifications with the TPS2047DR but differs in packaging designation and availability status.

Engineering Selection Recommendations

For applications currently utilizing the TPS2047DR, the TPS2057DR is the recommended substitute based on the following factors:

Product Status: The TPS2057DR maintains active product status with Texas Instruments, ensuring long-term availability and continued manufacturer support. The TPS2047DR is obsolete, and the TPS2047D is discontinued at DiGi Electronics, limiting procurement options.

Compliance & Certifications: Both the TPS2047DR and TPS2057DR are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), REACH unaffected status, and matching ECCN and HTSUS classifications. This ensures regulatory and supply chain compatibility.

Electrical & Mechanical Compatibility: The TPS2057DR maintains all critical electrical parameters including 250mA output current, 80mOhm on-resistance, 2.7V to 5.5V load voltage range, and identical fault protection mechanisms. The 16-SOIC package form factor is identical, enabling direct PCB-level substitution without layout modifications.

Functional Differences: The TPS2057DR supports both 1:2 and 1:1 input-to-output ratios with non-inverting input logic, compared to the TPS2047DR's 1:1 ratio with inverting input. Circuit designs must account for these functional differences during implementation.

Frequently Asked Questions (FAQ)

Q: Can the TPS2057DR directly replace the TPS2047DR in existing designs?

A: The TPS2057DR is electrically and mechanically compatible at the package level. However, the input logic differs (non-inverting vs. inverting) and the TPS2057DR supports additional 1:2 ratio configuration. Circuit-level evaluation is required to confirm functional compatibility with existing control logic.

Q: What is the primary reason for substitution?

A: The TPS2047DR is obsolete. The TPS2057DR is an active product from Texas Instruments with identical electrical specifications, ensuring procurement continuity and manufacturer support.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1). Regulatory and supply chain requirements are equivalent.

Q: Can the TPS2047D be used as an alternative?

A: The TPS2047D shares identical electrical specifications with the TPS2047DR but is discontinued at DiGi Electronics. This limits long-term availability and is not recommended for new designs or ongoing procurement.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution is determined by matching package type (16-SOIC), output configuration (N-Channel high-side), output current (250mA), on-resistance (80mOhm), load voltage range (2.7V ~ 5.5V), operating temperature (-40°C ~ 85°C), and fault protection mechanisms (current limiting, over-temperature, UVLO).

Q: Is the 16-SOIC package identical across all three parts?

A: Yes. All three parts use the 16-SOIC (0.154", 3.90mm Width) package, enabling direct PCB-level substitution without layout modifications.
