ESR is 200 mOhm — at 1000 µF and 4 V the ripple current capability is bounded by self-heating; check the dissipation factor against your ripple current at the switching frequency.

The two parts differ only in rated voltage — TAJD108K003RNJ is 3 V, this is 4 V. The package, capacitance, tolerance, and ESR are identical. If the circuit's voltage margin allows the higher rating, it is a functional drop-in.
