Crystal filter question?

[Low_Boy]

I have to replace a 10M15AA Filter. I am finding 10MA filters. Does the second A mean anything?
Thanks

My research indicated the second A was only used with a Uniden manufactured crystal. I never found a data sheet on the 10M15AA UNI crystals either, only photos. At least all the other manufactures with the single A had consistent specs. A meaning 2 pole, and B meaning 4 pole. Yes, I’d probably try to find another UNI crystal if possible, but I doubt another manufacture would be drastically different. At this time, finding a reliable state side source would be my main concern. China parts are ending up docked in stacked container boxes for weeks if not months.
