Substitute Part Grouping Explanation

Substitution for the TPS7A1128PDRVR is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.8V
• Output current capability of 500mA
• Maximum input voltage of 3.3V
• Dropout voltage specification of 0.14V @ 500mA
• Quiescent current of 2.6 µA
• Package type: 6-WSON (2x2) with exposed pad
• Operating temperature range: -40°C to 125°C
• Control features: Enable function
• Protection features: Over Current, Over Temperature, Under Voltage Lockout (UVLO)
• Regulatory compliance: ROHS3, REACH Unaffected

Only components matching all these parameters across the same base product number (TPS7A1128) and manufacturer are considered direct substitutes. Variations in tape and reel specifications or temperature grade designations do not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can TPS7A1128PDRVT be used as a direct replacement for TPS7A1128PDRVR?

A: Yes. Both parts are parametrically equivalent across all critical electrical specifications, including output voltage, current rating, dropout voltage, quiescent current, and protection features. The 6-WSON (2x2) package is identical, allowing direct PCB substitution without design changes.

Q: What is the difference between the PDRVR and PDRVT designations?

A: The suffix designations (PDRVR vs. PDRVT) indicate different tape and reel configurations or manufacturing date codes assigned by Texas Instruments. These designations do not affect electrical performance or functional characteristics.

Q: Are there any temperature grade differences between these parts?

A: No. Both the TPS7A1128PDRVR and TPS7A1128PDRVT operate across the identical temperature range of -40°C to 125°C (TJ). Temperature performance is equivalent.

Q: What protection features are included in both substitute parts?

A: Both components include Over Current protection, Over Temperature protection, and Under Voltage Lockout (UVLO). These features are identical across the TPS7A1128 product line.

Q: Are both parts RoHS compliant?

A: Yes. Both the TPS7A1128PDRVR and TPS7A1128PDRVT are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for global distribution.

Q: What is the package type for both parts?

A: Both parts use the 6-WSON (2x2) package with an exposed pad. This compact surface-mount package is identical between the two part numbers, ensuring PCB layout compatibility.

Q: Can these parts be used interchangeably in production?

A: Yes. The parametric equivalence and identical package specifications allow these parts to be used interchangeably in production environments without requiring design revisions or qualification testing.
