Not exactly, but it's very likely a more than adequate drop-in replacement.
The 63xx series boards are the newer X-series design with some improved specs and several significant improved capabilities. I can think of only 1 relatively obscure behavior that I consider *worse* under X-series.
Double-check the specs and pinouts, but you're very likely to be able to substitute seamlessly while gaining some benefits.

ALERT! LabVIEW's subscription-only policy came to an end (finally!). Unfortunately, pricing favors the captured and committed over new adopters -- so tread carefully.
