Substitute Part Grouping Explanation

Substitution for the TPS715A33DRVT is determined by strict equivalence across the following critical parameters: fixed output voltage (3.3V), output current rating (80mA), maximum input voltage (24V), voltage dropout specification (1.12V @ 80mA), quiescent current (4.2 µA), PSRR performance (60dB at 100kHz), protection features (over-current and reverse polarity), and operating temperature range (-40°C to 125°C). All substitute parts must maintain identical electrical performance and regulatory compliance (ROHS3, REACH Unaffected).

Two substitute parts are identified:

TPS715A33DRVR — Parametric equivalent with identical electrical specifications and 6-WSON (2x2) package. Product status is Active, providing superior long-term availability compared to the Last Time Buy main part.

TPS715A33DRBR — Manufacturer-recommended substitute with identical electrical specifications but different package configuration (8-SON 3x3). Product status is Active. Package change requires PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

TPS715A33DRVR is the preferred substitute for direct replacement applications. This part maintains identical package geometry (6-WSON 2x2), electrical specifications, and pin configuration as the TPS715A33DRVT. Active product status ensures extended availability and supply chain stability. No PCB layout modifications are required. ROHS3 compliance and MSL rating are equivalent.

TPS715A33DRBR is suitable for applications where package footprint modification is acceptable. The 8-SON (3x3) package provides the same electrical performance but requires PCB redesign. Active product status supports long-term procurement. This option is appropriate when layout constraints or thermal management improvements justify the engineering effort for package transition.

Both substitutes are manufactured by Texas Instruments under the TPS715 base product series and carry identical regulatory certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can TPS715A33DRVR be used as a direct drop-in replacement for TPS715A33DRVT?

A: Yes. TPS715A33DRVR is electrically and mechanically identical to TPS715A33DRVT, with the same 6-WSON (2x2) package footprint, pin configuration, and electrical performance. No design changes are required.

Q: What is the primary difference between TPS715A33DRVR and TPS715A33DRBR?

A: The primary difference is package configuration. TPS715A33DRVR uses 6-WSON (2x2), while TPS715A33DRBR uses 8-SON (3x3). Both deliver identical electrical performance (3.3V, 80mA, 1.12V dropout). Package selection depends on PCB layout constraints and thermal requirements.

Q: Why is TPS715A33DRVT classified as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued this specific part number variant. Substitutes with Active status (TPS715A33DRVR and TPS715A33DRBR) ensure continued availability and support for new designs and production continuity.

Q: Are all three parts RoHS compliant?

A: Yes. TPS715A33DRVT, TPS715A33DRVR, and TPS715A33DRBR are all ROHS3 Compliant with MSL rating of 2 (1 Year).

Q: Do the substitute parts maintain the same protection features?

A: Yes. All three parts include identical protection features: over-current protection and reverse polarity protection. Operating temperature range (-40°C to 125°C) is also identical across all variants.

Q: Which substitute should be selected for new designs?

A: TPS715A33DRVR is recommended for new designs requiring the 6-WSON (2x2) package. TPS715A33DRBR is appropriate if the 8-SON (3x3) package meets design requirements and PCB layout modifications are feasible.
