Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Identical Specifications): TPS73216DBVT is the direct equivalent from Texas Instruments. However, this part carries Last Time Buy status, indicating restricted future availability. Selection of this part is appropriate only for immediate, short-term production requirements or existing inventory management.

For Long-Term Design Support: RT9193-16GB from Richtek USA Inc. is recommended for new designs and ongoing production. This part is Active status, ensuring sustained availability. It exceeds the original specifications in output current (300mA vs. 250mA), quiescent current efficiency (130 µA vs. 550 µA), and power supply rejection ratio (70dB ~ 50dB vs. 58dB ~ 37dB). All parts maintain ROHS3 compliance and identical package geometry (SOT-23-5).

Frequently Asked Questions (FAQ)

Q: Can TPS73216DBVT be used as a direct replacement for TPS73216DBVR? A: Yes. Both parts are identical in electrical specifications and package type. The only difference is packaging format: TPS73216DBVR is supplied in bulk, while TPS73216DBVT is supplied in Tape & Reel format. Pin configuration and performance are identical.

Q: Is RT9193-16GB a pin-for-pin compatible substitute? A: Yes. RT9193-16GB maintains the same SOT-23-5 package and pin configuration. All electrical parameters required for substitution are met or exceeded. The part operates within the same temperature range and maintains ROHS3 compliance.

Q: What are the key differences between TPS73216DBVR and RT9193-16GB? A: Both deliver 1.6V fixed output with 5.5V maximum input. RT9193-16GB provides higher output current capability (300mA vs. 250mA), significantly lower quiescent current (130 µA vs. 550 µA), and superior power supply rejection ratio (70dB ~ 50dB vs. 58dB ~ 37dB). RT9193-16GB is Active status, ensuring long-term availability.

Q: Why is TPS73216DBVR marked as Obsolete? A: Obsolete status indicates the part is no longer manufactured by Texas Instruments. TPS73216DBVT (Last Time Buy) represents the final production run. For new designs, RT9193-16GB is the recommended alternative.

Q: Are there any moisture sensitivity considerations when substituting? A: TPS73216DBVR and TPS73216DBVT both carry MSL 2 (1 Year), while RT9193-16GB carries MSL 3 (168 Hours). This difference requires adherence to appropriate storage and handling protocols specific to each part's moisture sensitivity level.

Q: Do all substitute parts meet the same compliance standards? A: Yes. TPS73216DBVR, TPS73216DBVT, and RT9193-16GB are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
