TPS73616DBVR Equivalent & Substitute Parts

Part Overview

The TPS73616DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 1.6V at 400mA in a surface-mount SOT-23-5 package. The device is currently in Last Time Buy status, indicating end-of-life production. Alternative equivalent and substitute parts are necessary to ensure design continuity and long-term supply chain reliability for applications requiring 1.6V fixed-output regulation.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS73616DBVR is determined by the following critical parameters:

Parametric Equivalents maintain identical electrical specifications: fixed 1.6V output, 400mA current capacity, 5.5V maximum input voltage, 0.2V maximum dropout voltage, and SOT-23-5 package compatibility. These parts are direct functional replacements with no design modifications required.

Manufacturer-Recommended Alternatives provide functional substitution with relaxed output current specifications or adjusted output voltage ranges, provided the application can accommodate the parameter differences. These parts share the same package footprint and operating temperature range but may require circuit validation.

The following parameters are held constant across all acceptable substitutes:

• Package / Case: SOT-23-5 (SC-74A, SOT-753)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 125°C
• RoHS Compliance: ROHS3 Compliant
• Control Features: Enable function present

Parameter Comparison

Engineering Selection Recommendations

TPS73616DBVT is the parametric equivalent substitute. It maintains identical electrical and thermal specifications as the main part, including fixed 1.6V output, 400mA current capacity, and 0.2V dropout voltage. Both parts share Last Time Buy status, indicating similar supply constraints. This substitute requires no circuit modifications and provides direct form-factor compatibility.

TLV75801PDBVR is a manufacturer-recommended alternative from Texas Instruments with Active product status, ensuring long-term availability. It provides higher output current capacity (500mA versus 400mA) and lower quiescent current (35 µA versus 550 µA), beneficial for power-sensitive applications. The adjustable output range (0.55V ~ 5.5V) requires external resistor configuration to set 1.6V output. Maximum input voltage is 6V, and dropout voltage is higher at 0.88V @ 500mA. This substitute is suitable for designs where output current headroom and low standby power are priorities.

RT9193-16GB is a manufacturer-recommended alternative from Richtek USA Inc. with Active product status. It maintains fixed 1.6V output and 5.5V maximum input voltage. Output current is reduced to 300mA, making this substitute applicable only to applications with current requirements not exceeding 300mA. Quiescent current is lower at 130 µA. Moisture Sensitivity Level is MSL 3 (168 Hours) versus MSL 1 for the main part, requiring controlled storage conditions. This substitute is suitable for low-power applications with reduced current demands.

Frequently Asked Questions (FAQ)

Q: Can TPS73616DBVT be used as a direct replacement for TPS73616DBVR?

A: Yes. TPS73616DBVT is a parametric equivalent with identical electrical specifications, output voltage, current capacity, dropout voltage, and package footprint. No circuit modifications are required. Both parts are in Last Time Buy status.

Q: What is the key difference between TLV75801PDBVR and TPS73616DBVR?

A: TLV75801PDBVR has an adjustable output voltage range (0.55V ~ 5.5V) instead of fixed 1.6V output. To use this part, external resistors must be added to set the output to 1.6V. It offers higher output current (500mA) and significantly lower quiescent current (35 µA). TLV75801PDBVR is in Active status, ensuring continued availability.

Q: Can RT9193-16GB replace TPS73616DBVR in all applications?

A: RT9193-16GB maintains fixed 1.6V output and is package-compatible, but output current is limited to 300mA compared to 400mA. It is suitable only for applications where load current does not exceed 300mA. Moisture Sensitivity Level is higher (MSL 3), requiring controlled storage. Quiescent current is lower at 130 µA.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use SOT-23-5 package (SC-74A, SOT-753) with surface-mount configuration. Tape & Reel and Cut Tape packaging options may differ by supplier. Verify packaging availability with your distributor.

Q: What compliance certifications apply to these parts?

A: All parts listed are ROHS3 Compliant and REACH Unaffected. ECCN classification is EAR99 for all parts. Moisture Sensitivity Level varies: TPS73616DBVR, TPS73616DBVT, and TLV75801PDBVR are MSL 1 (Unlimited); RT9193-16GB is MSL 3 (168 Hours).

Q: Which substitute offers the best long-term supply availability?

A: TLV75801PDBVR and RT9193-16GB both have Active product status, indicating ongoing production and long-term availability. TPS73616DBVR and TPS73616DBVT are in Last Time Buy status, indicating limited future supply.
