Version C has an extra pin, pin 3. I have been able to find C in stock but not A. Is it possible to just cut pin 3 as they are both are on the same datasheet and connect to the same point. I am a rookie so please advise.
Hello wyndone.
Thank you for visiting the DigiKey TechForum!
Depending on your application, cutting pin 3 and installing the relay may work. The important thing to be aware of is that pin 3 will be electrically connected to pin 4 so if the small stub left from cutting off pin 3 touches anything conductive, you will get current flow into whatever it’s touching. This could be a dangerous situation depending on the amount of power you’re controlling and how/where it’s installed. It could quite possible cause a short or a shock hazard.
