Frequently Asked Questions (FAQ)

Q: Can TLV431IDBZR replace TLV431IDBZRG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The TLV431IDBZR operates within the same voltage range (1.24V to 6V), maintains ±1.5% tolerance, and is packaged in the same SOT-23-3 surface mount configuration. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and packaging availability. The TLV431IDBZRG4 is discontinued, while the TLV431IDBZR remains in active production. The substitute offers superior supply chain availability and is offered in standard Cut Tape and Digi-Reel® formats.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level 1 (unlimited). They meet the same regulatory and environmental standards.

Q: Is the SOT-23-3 package identical for both parts?

A: Yes. Both parts use the TO-236-3 / SC-59 / SOT-23-3 surface mount package with identical pin configuration and mechanical dimensions, ensuring direct PCB compatibility.

Q: What is the minimum cathode current requirement?

A: Both parts specify 80 µA cathode current, which must be maintained for proper voltage reference operation within the specified tolerance band.
