Is there a substitute for Triac NEC AC05D that I can use in my 24v GOOT 711as soldering station? The only place that has them will take a month to post otherwise.I don't have the confidence to to try another triac for fear of burning something out.If someone could work it out for me I would appreciate it.

That is a low/medium gate current triac so my usual sub (BTA08-600B) will not do I guess.
In that case the NTE5609 or BT137-600D which have a 10ma Igt will do.
Both have 600v/8amp so a bit of overkill 🙂
Try RS components in Auz look for sensitive triacs or 10ma gate current.

It seems odd that such an overspecced triac should fail.
I'd reverse engineer the board and see if it could be improved with a more robust triac.

It looks like an ordinary light dimmer triac to me.
One with a higher currant will not burn anything out as they are either on or off like a switch.
All the replacement will need is the same pin connections and a low enough gate currant.

I guess the question I would ask is why it failed? Some further investigation might be required. Did the heating element short out or was it killed by a nearby lightening strike? Insufficient heat sinking? Latent defect? (Hopefully this) If you are lucky there is no collateral damage and the soldering station works properly when the triac is replaced.
Thanks for the help fellas. Triac failed because the tip would come loose just about every time I used it and I forgot to tighten it up once,I used the tip to bend a capacitor pin into position and it bent the tip and shorted it out.(I run it hot) Replacement heater for it cost $38 so I ordered some heaters from fleabay got a pack of 5 for $6.50 and did a DIY.Looking at the boards etc.. it probably cost less than $38 to manufacture? Heres the rest of the specs that I forgot?

Soldering irons are so cheap now.
If mine fails I just bin it and buy new.
I just use Maplin cheapies and have very few problems.

In the Perth area, Altronics have BT136/500, BT137/500 available from stock at a couple of $$. 'Should be similar characteristics and I think either would be fine with a ~50W heating element. 'Also found this schematic of probably similar design: http://www.auelectronics.com/forum/index.php?action=dlattach;topic=208.0;attach=1693
Thread types could be better chosen for hot metal objects like irons. Too fine and they weld up, too coarse and they come unscrewed. I've had a few cheap products like that and whilst I resent paying high prices for very basic, traditional products from Weller, Adcola and some local manufacturers, their reliability issues had been worked out well enough over decades of product life.
Modern designs, for all the clever cost-cutting advantages and features, tend to wind up binned after a short life, whatever you paid for them. Any hope you may have, rests on brand credibility which unfortunately now, may only be as good as the crap they now rebadge to stay competitive.

Thanks Ian Ill get onto Altronics then.I couldnt agree with you more about these modern designs with there built in obsolescence,this Goot soldering station is supposed to be a professional model yet it looks like they've engineered the handpiece & heater to fail so they can sell the overpriced heater. Ive been looking at Hakko soldering stations,they seem to be the same thing at about half the price? Anyway Ill fix this and see how I go,any more trouble with it and its bin bound. LOL
I emailed RS for a sub for AC05D,the guy recommended BTA08-800CW3G ? I forgot to mention the 10ma gate. Would this triac be OK to use? Here is the datasheet link. http://docs-asia.electrocomponents.com/webdocs/10de/0900766b810de296.pdf
