Modern space electronics cannot last this long. It would require a significant effort to design similar hardware and have it fabbed today. Modern missions want capabilities that necessitate high transistor counts and that forces feature sizes that will never be robust against radiation effects over long durations.

New Horizons is similar, now at 18 years since launch and still counting. They're not quite 50 yet, but there's no reason to think either couldn't make it that long.
