The catalog entry we have is brief and doesn't give us more than the tooth count and the model it's tied to. The listing form SPRCUB-18T is the same part under a different number, so if you've seen it printed that way elsewhere, it's what you're looking at.
Give the shop a call to confirm this is the right tooth count and fit for your gearbox before you order — we don't have more detail on this one beyond what's stated here.
