The TAJC685M025SNJ: This is a 6.8 µF molded tantalum capacitor rated at 25 V DC, ±20% tolerance, from the TAJ series.
Temperature range and ESR — field-fit check
The 2 Ohm ESR at 25 °C means it can handle moderate ripple current — enough for a switching regulator output filter, but not a high-frequency point-of-load where you would reach for a polymer cap.
You can design it into a new BOM today and expect it to be available through independent distribution for the production run.
Package and footprint — size C 2312
Size C case per the TAJ series — 6.00 mm x 3.20 mm x 2.80 mm seated height. Surface-mount 2312 (6032 Metric) footprint. The molded body has clear polarity marking; on a rework bench you can see the band without a magnifier, which cuts down orientation mistakes during hand assembly.
