Genny,
first of all, you should ask yourself :
- what is the system impedance (50 Ohm or MOhms)
- signal levels
- current levels
- DC?
- AC?
- data lines?
- wave form?
- S/N requirements?¨
- Insulation requirements (flashover risk)
- pin/sleeve basic metal?
- ditto plating?
- migration condtions?
- nylon reinforcement?

Then you can judge the situation and decide what level of risk.
In certain situations not even Teflon is satisfactory.

Subject: [TN] Nylon connectors - moisture sensitivity


We have been told that a surface mount nylon connector we use is
moisture sensitive, and should be treated as equivalent to level 5a.
This is the highest level we have ever seen on any component we have
used of any type.  I didn't think that a connector could be moisture
sensitive.  Not heat tolerant, yes - we have melted a few - but moisture
sensitive?
What kind of damage can happen to a nylon connector from too much
moisture absorption?
Thanks in advance for your responses.

Genny
