Please Identify This... Transformer?

Attached are photos of a component from a handheld Tandy Electronic II (American) football game. It's a circular component, about 11mm wide. It should have 9 pins (1 pin has come off). The pins are about 2mm apart. I believe it's made of ferrite with wire wrapping around the core. The PCB marks this component as "T1". So with all that I'm assuming it's a transformer of some kind dating to somewhere around 1980 (based on date codes on the chips on the board it came from). The game is powered by 4 AA batteries and uses around 80 surface mount LEDs as the display for the game.

Is it a transformer? What kind of transformer or what kind of package or form would you call it? Is there a replacement that matches that footprint that I could find today?

Thanks

Its a HF transformer, probably from a switching supply circuit.. It would have been custom wound for the application. Replacement will be near impossible - even if you do a lot of work to determine all its parameters, you then have to try to match the core with something modern, wind a replacement and probably make a converter board for the pinout.   Instead, repair it.  Epoxy in a replacement pin and either extend any broken wires that led to that pin, or if the wire end is deeply buried under the winding, unwind it carefully noting wire positions, connections, gages and turn counts and rewind it with new wire to the same spec.

That is what I was afraid of. The broken wire is accessible so I'll give fixing it a go. Thanks.

Definitely the good way to go, assuming you can access that wire end.

Lacking that you would probably need to find the exact same model on eBay or somesuch and use it as an organ donor.  Unless it works, of course - then just use that one
