Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS76912DBVT is determined by electrical and mechanical parameter equivalence. All substitute parts must maintain identical specifications across the following critical parameters:

• Fixed output voltage of 1.2V
• Output current capability of 100mA
• Maximum input voltage of 10V
• Quiescent current of 28 µA
• PSRR of 60dB at 1kHz
• Operating temperature range of -40°C to 125°C
• SOT-23-5 package configuration
• Identical protection features (Over Current, Over Temperature, Reverse Polarity)
• Enable control feature

The identified substitutes are parametric equivalents manufactured by Texas Instruments under the TPS76912 base product number. Differences exist only in packaging format (Cut Tape vs. Tape & Reel) and product status classifications.

Parameter Comparison

Engineering Selection Recommendations

TPS76912DBVR is the primary substitute for TPS76912DBVT. Both parts are electrically and mechanically identical with full parametric equivalence. The TPS76912DBVR maintains Active product status and is available in both Cut Tape and Digi-Reel packaging formats, providing superior supply chain availability compared to the Last Time Buy status of the original part. This variant is suitable for all applications currently using TPS76912DBVT without design modifications.

TPS76912QDBVRQ1 is a parametric equivalent with automotive-grade qualification (AEC-Q100). This variant is appropriate for applications requiring automotive-grade components or operating in automotive environments. However, this part is listed as Discontinued at DiGi Electronics, limiting its availability for new procurement. Selection of this variant should be evaluated based on specific automotive qualification requirements and current inventory status.

For new designs or ongoing production requiring maximum supply chain continuity, TPS76912DBVR is the recommended selection due to its Active status and established availability through multiple packaging formats.

Frequently Asked Questions (FAQ)

Q: Can TPS76912DBVR directly replace TPS76912DBVT in existing designs?

A: Yes. TPS76912DBVR is a parametric equivalent with identical electrical specifications, output voltage, current rating, protection features, and SOT-23-5 package configuration. No design modifications are required for direct substitution.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual components cut from the reel, suitable for lower-volume applications and manual assembly. Tape & Reel (TR) packaging maintains components on continuous tape, optimized for high-volume automated assembly processes. Both formats contain identical components; packaging format selection depends on assembly methodology and volume requirements.

Q: Why is TPS76912QDBVRQ1 listed as a substitute if it is discontinued?

A: TPS76912QDBVRQ1 remains a valid parametric equivalent for applications requiring automotive-grade qualification (AEC-Q100). Existing inventory may be available through secondary sources. This variant should be considered only if automotive qualification is a mandatory design requirement and current stock is confirmed available.

Q: Are all three parts RoHS compliant?

A: Yes. TPS76912DBVT, TPS76912DBVR, and TPS76912QDBVRQ1 are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the significance of Last Time Buy status for TPS76912DBVT?

A: Last Time Buy status indicates that the manufacturer will no longer produce this specific part variant after a defined cutoff date. Existing inventory is limited. For applications currently using TPS76912DBVT, transition to TPS76912DBVR is recommended to ensure long-term supply chain stability.
