I tried a new PCBA factory for one of my boards design with an order of 200 PCS. I didn't notice my BOM had two references for the same Finder relay on same line. Until now, I was lucky enough for my other PCBA factory to order the right reference but this one ordered the wrong reference.
So now they are offering me two options :
- Cutting the 3 last pins of the relay which don't fit on my board
- Ordering 200 relays (but with the recent outbreak of Coronavirus, it will add up to 45 days for the production to be finished + additional 10-15% of total paid price)
As the wrong relay is a changeover one and my boards stay most of the time "open", the cut pins will have a voltage applied on them and some traces are just below. So I don't think it's a good idea to do this. But as it will add lead time + costs, I want to be sure.
The right reference is :
- Finder 62.23.9.012.0300
Wrong one (on pictures below) :
- Finder 62.23.9.012.0000
These relays make contact for 230VAC 3-phases voltage. We use them with up to 10A currents.
Here's the part of the design concerned :

If they have the same current rating, I would cut them. Further, if the potential of the most upper trace is not 230VAC, I would add a piece of Kapton tape (or Koptan).
