Can the single pole LA1DN and LADN auxiliary contact module be mounted on the TeSys contactors?

In which contactors can the LA1DN and LADN auxiliary contacts be mounted?

Auxiliary contacts for the Tesys D line

Tesys D-Line and Tesys F

These contacts will only fit on the following contactors:
Front mount only for LC1D40 through LC1D115 devices and LC1D40A - LC1D65A.
Left side mount only to LC1F contactors

Will a single circuit auxiliary contact block, like a LADN10 or LADN01, fit onto the Tesys D09-D38 amp contactors?
