The original FBR46 relay was manufactured by Fujitsu, a relay which became one of the popular classic telecomms. small signal relay. This relay is no longer manufactured, obsolete, and very difficult to source.
The original Fujitsu FBR46ND datasheet is downloadable below.
Originally manufactured in coil voltages ranging from 1.5V to 24V dc, the most popular coil voltages used at the time in the telecomms and control industries were 5V, 12V and 24V
The Cephos C-BT53 relay module is a drop-in replacement for this obsolete Fujitsu FBR46 relay
