Procurement Notes

Verify the complete part number including suffixes such as Q1 for automotive grade and DCKR for the SC-70-5 reel package. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for automotive components.

Selection Notes

Select this component when automotive certification and high precision are required in a small footprint. Compare against TL4050A series variants if tighter initial accuracy tolerances are necessary for the specific application design requirements.

Part Context

This device belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades, with the B25 variant specifically providing a 2.5 V output. The Q1 suffix denotes automotive qualification, distinguishing it from standard industrial grade parts.

Replacement Considerations

TL4050B25IDCKRQ1 offers higher initial accuracy (0.1%) in the same package and automotive qualification.
