Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2047ADR is determined by strict equivalence across the following critical parameters:

• 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 independent outputs
• Current - Output (Max): 250mA rated capacity
• Voltage - Load: 2.7V ~ 5.5V operating range
• Rds On (Typ): 80mOhm on-resistance specification
• Operating Temperature: 0°C ~ 85°C range
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO features
• RoHS Status: ROHS3 Compliant certification

The TPS2057ADR qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications. Differences in input logic type (Inverting vs. Non-Inverting) and input:output ratio configuration do not affect the core switching functionality for applications requiring these core parameters.

Parameter Comparison

Engineering Selection Recommendations

The TPS2057ADR is the primary substitute for the obsolete TPS2047ADR. This substitution is supported by:

• Identical electrical performance across all critical switching parameters
• Matching 16-SOIC package footprint for direct PCB compatibility
• Active product status with current manufacturing availability
• ROHS3 compliance and MSL 1 rating matching the original specification
• Equivalent fault protection architecture (Current Limiting, Over Temperature, UVLO)

The TPS2057ADR maintains full parametric equivalence while offering the advantage of active product status, ensuring long-term component availability and supply chain continuity for designs currently using the obsolete TPS2047ADR.

Frequently Asked Questions (FAQ)

Q: Can the TPS2057ADR be used as a direct replacement for the TPS2047ADR?

A: Yes. The TPS2057ADR matches all critical electrical and mechanical parameters of the TPS2047ADR, including package type, output current rating, voltage range, on-resistance, and fault protection features. The 16-SOIC package footprint is identical, enabling direct PCB compatibility.

Q: What is the difference between the TPS2047ADR and TPS2057ADR?

A: The primary differences are product status and input logic configuration. The TPS2047ADR is Obsolete with Inverting input logic, while the TPS2057ADR is Active with Non-Inverting input logic. Both devices maintain identical output switching characteristics, load voltage range, current capacity, and protection features.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both the TPS2047ADR and TPS2057ADR use the 16-SOIC (0.154", 3.90mm Width) package. Pin count, spacing, and physical dimensions are identical, ensuring seamless PCB integration without layout modifications.

Q: Does the TPS2057ADR meet the same compliance standards as the TPS2047ADR?

A: Yes. The TPS2057ADR is ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the TPS2047ADR. Both parts carry identical environmental and regulatory certifications.

Q: Why should I consider the TPS2057ADR over the TPS2047ADR?

A: The TPS2047ADR is classified as Obsolete, creating long-term supply and support risks. The TPS2057ADR is an Active product with current manufacturing support, ensuring reliable component availability and technical documentation access for ongoing production and design support.
