    Default Sub parts for SSRneon-G2LED

    Going through some old boxes I came across some SSRneon-G2-LED boards I never assembled.

    The LED listed in the BOM is obsolete, has a operating voltage of 2.5 V max (2 V typ) . I am looking to use an LED with a 1.9-2.1V forward voltage range. I just wanted to verify that I do not need to change the 220 ohm (R1-4) or the 680 ohm (R9). According to my math, I don't believe I do, but wanted to check with the experts.

    Thank you,

    You should be OK. With the 2.5v LED and 680 ohm, it's drawing about 3.7ma. With the newer LED you'd pull around 4.5ma, still well within most LEDs current capacity.
