Capacitance, voltage, and ESR — the BOM-fit numbers
This TAJW476M010RNJ is a 47 µF, 10 V rated molded tantalum capacitor with ±20% tolerance. The 1.4 Ohm ESR at 100 kHz is the figure that governs ripple current capability — in a 10 V rail with 100 mV ripple, the capacitor dissipates roughly I² × 1.4, so the thermal rise stays within the molded case limits if the ripple current is kept under 300 mA RMS.
Package and footprint — 2312 (6032 Metric)
The 2312 case code (6.00 mm × 3.20 mm footprint, 1.50 mm seated height) is a standard tantalum size. The W manufacturer code matches the 2312 body.
The molded construction and general-purpose feature set keep it a drop-in replacement for most standard tantalum applications in this voltage and capacitance range.
This part is still a valid design-in choice. No direct second-source cross-reference is published, but the TAJ series is a widely used industry-standard footprint, so functionally equivalent parts from other manufacturers (same case, voltage, capacitance, ESR) exist on the market.
