The 5 Ohm ESR (Equivalent Series Resistance) is the headline parametric — it defines how much ripple current the cap can handle before self-heating becomes a concern. For a 6.8 µF part at 6.3 V, this ESR is moderate; expect a ripple current capability in the tens of mA range. If your rail needs lower impedance at the switching frequency, a lower-ESR TAJ variant (same footprint, different suffix) is the swap. Product status is Active.","metaTitle":"TAJA685M006RNJ KYOCERA AVX 6.8 µF Molded Tantalum Cap, 1206","metaDescription":"TAJA685M006RNJ from KYOCERA AVX: 6.8 µF ±20%, 6.3 V rated, 5 Ohm ESR, -55°C to 125°C.

The key difference to check is ESR: this part has a 5 Ohm ESR. If the original cap had a lower ESR (e.g., 2 Ohm), the replacement will have higher ripple-induced heating and may not meet the same ripple current budget.
