TPS2057ADR Equivalent & Substitute Parts

Part Overview

The TPS2057ADR is an active power management integrated circuit manufactured by Texas Instruments, classified as a Power Management (PMIC) device. It functions as a power switch/driver with N-channel output configuration, supporting 1:2 and 1:1 input-to-output ratios with a maximum output current of 250mA. The device is currently in active product status with 5100 units available in new original inventory. Alternative equivalent parts may be required due to supply constraints, regional availability, or specific operating temperature requirements for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2057ADR is determined by strict equivalence across the following critical parameters:

• Manufacturer and Base Product Number: Both the main part and substitute must originate from Texas Instruments and share the base product number TPS2057
• Functional Specifications: Identical switch type (General Purpose), output configuration (High Side, N-Channel), number of outputs (3), and input-to-output ratios (1:2, 1:1)
• Electrical Performance: Matching load voltage range (2.7V ~ 5.5V), maximum output current (250mA), and on-resistance (80mOhm typical)
• Protection Features: Identical fault protection mechanisms (Current Limiting Fixed, Over Temperature, UVLO)
• Package and Mounting: Same physical package (16-SOIC) and surface mount technology
• Compliance Standards: Equivalent RoHS3 compliance and MSL rating (1 - Unlimited)

The TPS2057DR qualifies as a direct substitute based on these parameters. The primary difference is the extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 85°C), which represents an expansion of the acceptable operating envelope and does not restrict substitution in applications within the original temperature specification.

Parameter Comparison

Engineering Selection Recommendations

The TPS2057DR is a direct functional equivalent to the TPS2057ADR. Both devices maintain active product status with Texas Instruments and carry identical ROHS3 compliance and MSL ratings, ensuring equivalent environmental and regulatory compliance for manufacturing and deployment.

The TPS2057DR features an extended operating temperature range of -40°C to 85°C compared to the TPS2057ADR's 0°C to 85°C specification. This extended lower temperature limit does not restrict its use in applications designed for the standard temperature range and provides additional operational flexibility for applications requiring low-temperature performance.

Selection between these parts should be based on supply availability, inventory levels, and specific application temperature requirements. The TPS2057DR with 720 units in stock and the TPS2057ADR with 5100 units in stock represent the available inventory positions for component procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the TPS2057DR replace the TPS2057ADR in existing designs?

A: Yes. The TPS2057DR is electrically and mechanically equivalent to the TPS2057ADR across all critical parameters including output configuration, current rating, voltage specifications, protection features, and package type. The extended operating temperature range of the TPS2057DR does not create incompatibility with designs specified for the standard temperature range.

Q: What is the difference between the TPS2057ADR and TPS2057DR?

A: The primary difference is the operating temperature specification. The TPS2057ADR operates from 0°C to 85°C, while the TPS2057DR operates from -40°C to 85°C. All other electrical and mechanical characteristics are identical.

Q: Are both parts pin-compatible?

A: Yes. Both the TPS2057ADR and TPS2057DR use the identical 16-SOIC package with matching pinout and footprint, enabling direct substitution on printed circuit boards without layout modifications.

Q: Do both parts have the same protection features?

A: Yes. Both devices include identical fault protection mechanisms: fixed current limiting, over-temperature protection, and under-voltage lockout (UVLO).

Q: What compliance certifications apply to both parts?

A: Both the TPS2057ADR and TPS2057DR are ROHS3 compliant and carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
