You should probably look up panchromatic and orthochromatic to clear up some confusion.

Panchromatic emulsions are sensitive to blue, green, and red light. Panchromatic films are historically speaking a newer development than orthochromatic films.

Orthochromatic emulsions have no, or very low, sensitivity to red light, recording well in blue and green. They were developed before panchromatic films.

You can have panchromatic or orthochromatic films at a wide range of film speeds, so speaking as if "Pan" is a clear reference to slower films is confusing.

Delta 3200, TMZ-3200, HP5+, Tri-X, TXP, and nearly all medium and high speed films are panchromatic.
