The external terminals on the base of DX-9100 makes it about 2 inches taller but about one inch narrower than the FX-PCA3611. Replacement in the same enclosure space may be possible when not using all of the I/Os on the DX. Special consideration is required for DX-9100 Series controllers that mount on the face of an enclosure. You may need to find a retrofit solution such as using a new panel enclosure.

Consider that the onboard I/O count for an FX-PCA3611 is slightly less than a DX-9100. As a result, you may need to add an FX-PCX Expansion I/O Module even if the old installation did not use XT/XP extension modules.

Installations that used one or more extension module sets may need extensive rearranging to accommodate the equivalent point count FX-PCXs. Some space is regained as the XT communication module is removed.
