1. TLV431CDBVT Substitution Conclusion
Critical parameter analysis reveals partial deviations between the TLV431CDBVT and the original TS431ILT, warranting careful consideration before substitution. The TLV431CDBVT offers an output current of only 15mA (compared to 30mA for the original), which may preclude direct replacement in circuits requiring higher load current or lower current‑limiting resistance. Its tolerance is ±1.5%, providing better accuracy than the original’s ±2%, but the temperature coefficient is unspecified—potentially implying temperature‑stability risks. Additionally, its cathode current is 80µA (versus 60µA for the original), resulting in slightly higher quiescent power dissipation. If the actual operating current remains below 15mA and higher accuracy is desired, the TLV431CDBVT could serve as an alternative, though full temperature‑range performance validation is recommended.
2. TS431IYLT Substitution Conclusion
The TS431IYLT matches the original TS431ILT in all key electrical parameters—including output voltage range, output current, tolerance, temperature coefficient, and package—making it a drop‑in replacement. The sole distinction is that the TS431IYLT is AEC‑Q100 qualified, imposing stricter requirements for reliability, operating temperature range, and quality control, thus suiting it for harsh environments such as automotive electronics. In general industrial or consumer applications, the TS431IYLT can be regarded as an upgraded version of the original, with no compatibility or stability risks, though it may introduce some cost variation.
