help to id and purchase pcb transformer from LOWRANCE GPS

I have a mini/micro transformer that is mounted on a pcb inside my lowrance gps/plotter. I have removed it from the pcb. It has 5 through hole pins, 3 pins out bottom one side and 2 pins out bottom on opposite side. The transformer has yellow tape around black plastic frame labeled GCi 0550 LF 029-0110-02 with yellow tape around the windings. I need one of these or a suitable replacement. please help id and locate to purchase. Thanks I can post pic if needed.
