TPS73219DBVT Equivalent & Substitute Parts

Part Overview

The TPS73219DBVT is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) device. It delivers a fixed positive output of 1.9V at 250mA with a maximum dropout voltage of 0.15V. The device integrates protection features including over-current, over-temperature, short-circuit, and reverse-polarity protection, making it suitable for low-voltage power supply applications requiring regulated output with integrated safety mechanisms.

The TPS73219DBVT carries a Last Time Buy product status, indicating that Texas Instruments has discontinued this variant. This necessitates identifying equivalent substitute parts to maintain design continuity and ensure long-term component availability for production and maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the TPS73219DBVT is determined by strict parametric equivalence across the following critical criteria:

Output voltage specification (1.9V fixed), output current capability (250mA minimum), input voltage tolerance (5.5V maximum), dropout voltage performance (0.15V @ 250mA), package form factor (SOT-23-5), operating temperature range (-40°C to 125°C), and integrated protection features (over-current, over-temperature, short-circuit, reverse-polarity).

The substitute part must belong to the same TPS732xx series from Texas Instruments and maintain identical electrical performance across all specified parameters. Packaging format differences are permitted only when the physical footprint and pin configuration remain compatible with the original design.

Parameter Comparison

Engineering Selection Recommendations

The TPS73219DBVR is a direct parametric equivalent to the TPS73219DBVT. Both devices share identical electrical specifications, performance characteristics, and protection features across all critical operating parameters.

The primary distinction between these parts is packaging format: the TPS73219DBVT is supplied in Tape & Reel (TR) format, while the TPS73219DBVR is supplied in Cut Tape (CT) format. This difference affects component handling and assembly processes but does not impact electrical performance or functional compatibility.

The TPS73219DBVR carries an Active product status, ensuring continued availability and long-term supply stability. This makes it the preferred selection for new designs and ongoing production requirements where the TPS73219DBVT is no longer available due to its Last Time Buy status.

Both parts maintain ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001), ensuring compatibility with environmental and trade compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the TPS73219DBVR directly replace the TPS73219DBVT in existing designs?

A: Yes. The TPS73219DBVR is a direct parametric equivalent with identical electrical specifications, output voltage, current rating, dropout voltage, protection features, and operating temperature range. The only difference is the packaging format (Cut Tape vs. Tape & Reel), which does not affect circuit performance or PCB footprint compatibility.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging supplies the same components on shorter tape segments, typically used for lower-volume orders or manual assembly. Both formats contain identical components with the same electrical and mechanical specifications.

Q: Why is the TPS73219DBVT marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued this specific part variant. Customers must transition to alternative parts, such as the TPS73219DBVR, to ensure continued component availability for future production and maintenance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the TPS73219DBVT and TPS73219DBVR maintain identical RoHS3 compliance, REACH status, ECCN classification, and HTSUS codes. They are fully equivalent from a regulatory and environmental compliance perspective.

Q: What should be considered when transitioning from TPS73219DBVT to TPS73219DBVR?

A: The transition is straightforward due to parametric equivalence. Primary considerations are packaging format compatibility with your assembly process (Cut Tape vs. Tape & Reel) and component availability from your supplier. No circuit redesign or PCB modifications are required.
