Default SCR or TRIAC?

I need to replace an SCR in a circuit (auto timing light) its a TO92 case so I was limited to what was available. Decided an equivalent was a Motorola BRY55-400 and this was available from my supplier The data sheet identifies it as a Silicon Controlled Rectifier yet when it arrived from the supplier it was invoiced as a TRIAC. What should I believe?

I would believe the datasheet over the invoice, but check the part to make sure.

Hi Wombat2
Motorola says it's an SCR in their data sheet
http://www.ortodoxism.ro/datasheets/.../BRY55-400.pdf
so you should be OK.
Just out of curiosity, what was the part number of the failed one?
Cheers
Rob
