Substitute Part Grouping Explanation

Substitution eligibility for the TPS76316DBVR is determined by the following critical parameters:

Output voltage matching at 1.6V fixed output
Output current capability of 150mA minimum
Input voltage maximum rating of 10V or greater
SOT-23-5 package compatibility
Surface mount mounting type
Operating temperature range covering -40°C to 125°C
RoHS3 compliance

Substitute parts are grouped into two categories: direct parametric equivalents with identical electrical specifications, and manufacturer-recommended alternatives with enhanced performance characteristics or different product status classifications.

Engineering Selection Recommendations

For direct replacement of TPS76316DBVR in active production, TPS76316QDBVRG4Q1 is the primary selection. This part maintains identical electrical specifications while offering Active product status and automotive-grade qualification (AEC-Q100), ensuring long-term availability and supply chain stability.

TPS70916DBVR serves as an enhanced alternative with Active status, offering superior quiescent current performance (2.05 µA versus 100 µA) and higher input voltage tolerance (30V maximum). This part is suitable for applications where lower power consumption and higher input voltage headroom provide design advantages.

For applications requiring extended temperature operation to 125°C, TPS76316QDBVRG4Q1 remains the recommended choice. Alternatives from ABLIC Inc. (S-1200B16-M5T1U and S-L2980A16MC-TF-U) operate to 85°C maximum and are suitable only for designs with reduced temperature requirements.

All recommended substitutes maintain SOT-23-5 package compatibility, RoHS3 compliance, and the specified 1.6V output voltage with 150mA current capability.

Frequently Asked Questions (FAQ)

Q: Can TPS70916DBVR replace TPS76316DBVR in all applications?

A: TPS70916DBVR is electrically compatible for 1.6V, 150mA applications. The primary difference is enhanced quiescent current performance (2.05 µA versus 100 µA) and higher input voltage rating (30V versus 10V). Applications operating within 10V input maximum will function identically. The higher input voltage rating provides additional design margin without penalty.

Q: What is the difference between TPS76316DBVR and TPS76316DBVT?

A: Both parts are parametrically identical with 1.6V output, 150mA current, and SOT-23-5 packaging. The difference is packaging format: DBVR is Cut Tape, while DBVT is Cut Tape & Digi-Reel. Both are Last Time Buy status. Selection depends on procurement and handling requirements.

Q: Are ABLIC parts suitable replacements?

A: S-1200B16-M5T1U and S-L2980A16MC-TF-U maintain 1.6V output, 150mA current, and SOT-23-5 compatibility. Both are Active status with superior quiescent current (1 µA). Operating temperature is limited to -40°C to 85°C, making them unsuitable for applications requiring full -40°C to 125°C range. Use only when temperature requirements permit.

Q: Why is TPS76316QDBVRG4Q1 recommended over TPS76316DBVR?

A: TPS76316QDBVRG4Q1 is Active status with automotive qualification (AEC-Q100), ensuring continued availability and supply chain support. Electrical specifications are identical to TPS76316DBVR. Active status provides design continuity for new and ongoing production.

Q: Are the Torex XC6209 and XC6204 series compatible?

A: XC6209B182MR-G and XC6209F182MR-G have 1.8V output, not 1.6V. These parts are not direct substitutes for 1.6V applications. XC6204B182MR-G also specifies 1.8V output. Output voltage mismatch prevents functional equivalence.

Q: What packaging considerations apply to substitution?

A: All recommended substitutes use SOT-23-5 (SC-74A) surface mount packaging with identical pinout and footprint. Packaging format differences (Cut Tape versus Tape & Reel) do not affect circuit compatibility, only procurement and handling logistics.
