Will it do the job for what, Cat? That looks to me like an ordinary LED...I'd put it in series with a 220 ohm resistor to run it at 9V (180 ideal, 220 is close enough); (supply voltage - LED voltage/LED current from the data sheet).   Unless what you're building requires a certain LED, that should do just fine as an indicator. 
MXR Dist +, TS9/808, Easyvibe, Big Muff Pi, Blues Breaker, Guv'nor.  MOSFace, MOS Boost,  BJT boosts - LPB-2, buffers, Phuncgnosis, FF, Orange Sunshine & others, Bazz Fuss, Tonemender, Little Gem, Orange Squeezer, Ruby Tuby, filters, octaves, trems...

just to make me sure about this topic, I ask a question once again :icon_biggrin:
Can we use any color other than red led as an indicator? For example in the millenium by pass? I will buy blue or green led for millenium bypass.
