Equivalent & Substitute Parts for DTA143TCAT116
Part Overview
DTA143TCAT116 is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Rohm Semiconductor. This device features a maximum collector current of 100 mA, a collector-emitter breakdown voltage of 50 V, and a base resistor of 4.7 kOhms. It is provided in a surface-mount TO-236-3 (SOT-23-3, SC-59) package and has a power rating of 200 mW. The part is currently active and compliant with RoHS3, REACH, and has an unlimited Moisture Sensitivity Level (MSL 1).
Finding alternative or substitute models is necessary to ensure continuity of supply, maintain design compatibility, and support multi-source qualification for this product category, especially when inventory management, lead time, or procurement risk are critical.
