Active production — standard commercial tantalum
The TPSD686M020R0070: This is a general-purpose part (no low-ESR or high-reliability screening), so it suits bulk decoupling, output filtering, and hold-up capacitor roles in power supplies where the 70 mOhm ESR is acceptable for the ripple current budget.
68 µF, 20 V, 70 mOhm — the fit triad
It is not a low-ESR part, so it is not the first choice for high-ripple POL converters, but it works for general bulk storage. The capacitance tolerance is ±20%, typical for standard tantalum — the spread is wider than MLCC but acceptable for decoupling where the exact value is not critical.
D case 2917 — standard footprint, wide second-source
This footprint is widely second-sourced across manufacturers — a board laid out for a D-case tantalum can accept equivalents from Kemet, Vishay, or other suppliers without a layout change. Molded construction means the part has a solid epoxy body with a flat top for pick-and-place handling. The tape-and-reel packaging (Cut Tape or full reel) is standard for volume assembly.
