Features:
- Officially identified by Honeywell as part number 51305348-100 with the item description “MAU ASSY.”
- Grouped under Infrastructure in Honeywell’s System HINTS spare-parts listing for legacy system support.
- Requires exact assembly, connector and installed coax LCN/UCN context verification before replacement.
Honeywell 51305348-100 is a legacy infrastructure MAU assembly. The official cited record establishes the part identity and group but does not publish additional electrical or environmental ratings, so selection must rely on the complete part number and the installed system.
Official source: Honeywell. Product identity is taken from the September 2022 System HINTS Infrastructure spare-parts table.

Important Notice: Other accessories, manuals, cables, calibration data and software are not included unless listed in the item description. All prices are shown in USD.
Honeywell’s official spare-parts table places 51305348-100 in the Infrastructure group and describes it as a MAU assembly. It should therefore be evaluated as part of the installed legacy network hardware rather than as a general-purpose controller or I/O module.
Confirm the host system, assembly position and connectors against the maintained site documentation before replacement.
Honeywell identifies coax LCN/UCN infrastructure as a phased-out legacy architecture. Continued service requires disciplined spare identification, verified system backups and a documented maintenance plan for the existing network.
The exact 51305348-100 assembly should be checked from its part label because the cited Honeywell record does not state a like-for-like successor.
For modernization, Honeywell positions Experion LCN/ELCN as the migration path from legacy coax infrastructure. This is a system-level transition rather than a direct plug-in replacement for 51305348-100.
Record the installed node, coax connections, cabinet location and dependent hardware before defining a migration or replacement scope.
