TPS40071PWP Equivalent & Substitute Parts

Part Overview

The TPS40071PWP is a buck regulator positive output step-down DC-DC controller IC manufactured by Texas Instruments in a 16-HTSSOP package. This device functions as a transistor driver for step-down topology applications with a single output phase. The TPS40071PWP is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS40071PWP is determined by strict equivalence across the following critical parameters:

• Topology: Buck (step-down)
• Output Type: Transistor Driver
• Output Configuration: Positive
• Number of Outputs: 1
• Output Phases: 1
• Voltage Supply Range: 4.5V ~ 28V
• Switching Frequency: Up to 1MHz
• Maximum Duty Cycle: 93%
• Synchronous Rectifier: Yes
• Package / Case: 16-PowerTSSOP (0.173", 4.40mm Width)
• Operating Temperature Range: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

Two substitute parts meet these criteria: the TPS40077PWP (MFR Recommended) and the TPS40070PWP (Parametric Equivalent).

Parameter Comparison

Engineering Selection Recommendations

The TPS40077PWP is the primary substitute for the TPS40071PWP. This part carries an "Active" product status from Texas Instruments, indicating current manufacturing and long-term availability. All electrical and mechanical parameters are identical to the TPS40071PWP, with the exception that the TPS40077PWP omits the Enable control feature present in the original part. For applications requiring Enable functionality, this difference must be evaluated against design requirements.

The TPS40070PWP is a parametric equivalent that maintains all critical electrical and mechanical specifications. However, this part is designated "Last Time Buy," indicating limited remaining availability. The TPS40070PWP includes the Enable control feature matching the TPS40071PWP. Selection of this part should account for its approaching end-of-life status and potential supply constraints.

Both substitute parts are ROHS3 compliant with MSL 2 (1 Year) ratings, matching the original part's environmental and regulatory compliance profile.

Frequently Asked Questions (FAQ)

Q: Can the TPS40077PWP directly replace the TPS40071PWP in existing designs?

A: The TPS40077PWP is electrically and mechanically compatible with the TPS40071PWP across all specified parameters. The primary difference is the absence of the Enable control feature in the TPS40077PWP. If the Enable function is not utilized in the original design, direct substitution is valid. If Enable functionality is required, design modification or selection of the TPS40070PWP is necessary.

Q: What is the difference between the TPS40077PWP and TPS40070PWP?

A: Both parts are parametrically equivalent to the TPS40071PWP. The TPS40077PWP has "Active" product status with higher current availability (2248 Pcs). The TPS40070PWP has "Last Time Buy" status with lower availability (1900 Pcs) and includes the Enable control feature. Selection depends on design requirements and supply chain considerations.

Q: Are all three parts in the same package?

A: Yes. The TPS40071PWP, TPS40077PWP, and TPS40070PWP are all housed in the 16-PowerTSSOP package (0.173", 4.40mm Width), enabling direct PCB-level substitution without layout modifications.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant with MSL 2 (1 Year) ratings. Regulatory compliance across REACH and ECCN classifications is identical.

Q: Which substitute should I select for new production?

A: The TPS40077PWP is recommended for new production due to its "Active" status and superior availability. Verify that the absence of the Enable control feature does not impact your application requirements.
