Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS76601D is determined by functional equivalence across the following critical parameters:

Functional Requirements:

• Output configuration (positive adjustable)
• Output current capability (minimum 250mA)
• Adjustable output voltage range (minimum 1.25V to 5.5V coverage)
• Control features (Enable, Power Good)
• Protection mechanisms (over-current, over-temperature)

Environmental & Compliance Requirements:

• Operating temperature range (-40°C to 125°C)
• RoHS3 compliance
• MSL rating of 1 or better

Package Compatibility:

• Surface mount technology
• Pin-compatible or functionally equivalent package footprint

Two substitute parts are identified based on these criteria: TPS76601DG4 (parametric equivalent) and TPS7A2501DRVR (manufacturer-recommended upgrade).

Parameter Comparison

Engineering Selection Recommendations

TPS76601DG4 (Parametric Equivalent): This part is a direct parametric equivalent to the TPS76601D, sharing identical electrical specifications and 8-SOIC package. Both devices are classified as obsolete. Selection of TPS76601DG4 is appropriate for applications requiring exact parameter matching and existing PCB designs with 8-SOIC footprints. However, long-term availability may be limited due to obsolete status.

TPS7A2501DRVR (Manufacturer-Recommended Upgrade): Texas Instruments designates TPS7A2501DRVR as the recommended substitute. This device is classified as active, ensuring ongoing availability and support. The TPS7A2501DRVR provides enhanced specifications including higher maximum input voltage (18V vs. 10V), extended output voltage range (1.24V to 17.66V), increased output current (300mA vs. 250mA), and significantly lower quiescent current (4.5 µA vs. 50 µA). The package changes from 8-SOIC to 6-WDFN Exposed Pad, requiring PCB redesign. All devices maintain ROHS3 compliance, MSL rating of 1, and identical operating temperature range.

For new designs or long-term production continuity, TPS7A2501DRVR is the preferred selection due to active product status and superior performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TPS76601DG4 be used as a direct replacement for TPS76601D? A: Yes. TPS76601DG4 is a parametric equivalent with identical electrical specifications and 8-SOIC package. No circuit modifications are required. Both devices are obsolete, so availability may be limited.

Q: What are the key differences between TPS76601D and TPS7A2501DRVR? A: The primary differences are: (1) Product status—TPS7A2501DRVR is active while TPS76601D is obsolete; (2) Package—TPS7A2501DRVR uses 6-WDFN Exposed Pad instead of 8-SOIC, requiring PCB redesign; (3) Electrical performance—TPS7A2501DRVR offers higher input voltage rating (18V), extended output voltage range, higher output current (300mA), and lower quiescent current (4.5 µA). All other functional features including control and protection mechanisms are compatible.

Q: Is TPS7A2501DRVR pin-compatible with TPS76601D? A: No. TPS7A2501DRVR uses a 6-WDFN Exposed Pad package while TPS76601D uses 8-SOIC. Pin count and footprint differ, requiring PCB layout modifications. Functional compatibility exists, but physical substitution on existing boards is not possible without redesign.

Q: Which substitute should I select for a new design? A: TPS7A2501DRVR is recommended for new designs. It is classified as active, ensuring long-term availability and manufacturer support. It provides superior performance specifications and enhanced protection features including Under Voltage Lockout (UVLO).

Q: Are all three parts RoHS3 compliant? A: Yes. TPS76601D, TPS76601DG4, and TPS7A2501DRVR are all ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the impact of changing from TPS76601D to TPS7A2501DRVR on quiescent current? A: Quiescent current decreases from 50 µA to 4.5 µA, representing an 91% reduction. This improvement reduces standby power consumption and is beneficial for battery-powered or low-power applications.
