Cephos C-BT53 Relay module

The C-BT53 relay module is manufactured by Cephos Electronic Circuits Ltd. in the UK - a relay module to replace several classic telecomms. small signal relays that have not been manufactured for several years and are now obsolete and very difficult to source.

The more common of these obsolete relays are the Fujitsu BT53 and BT53W, Panasonic DF2, Omron G5A and Fujitsu FBR46 relays.

The Cephos C-BT53 5V, 12V and 24V coil voltage versions are normally ex-stock and available for immediate shipping, other coil voltages are manufactured to order on a short lead time ( subject to component availability)

C-BT53 relay module

With identical pinning and footprint the C-BT53 relay module achieves all of the functionality of the original BT53, BT53/W, DF2, G5A and FBR46 relays offering a simple drop in solution, either fitted into an existing pcb dil connector or soldered straight into a printed circuit board.
