RoHS Compliance and Lead Free Relay Information
1. General Information
Relays produced after the specific date code that is indicated on each data sheet are lead-free
l
now. Most of our signal and power relays are lead-free. Please refer to Lead-Free Status Info.
(http://www.fujitsu.com/us/downloads/MICRO/fcai/relays/lead-free-letter.pdf)
Lead free solder paste currently used in relays is Sn-3.0Ag-0.5Cu.
l
All signal and most power relays also comply with RoHS. Please refer to individual data
l
sheets. Relays that are RoHS compliant do not contain the 5 hazardous materials that
are restricted by RoHS directive (lead, mercury, chromium IV, PBB, PBDE).
It has been verified that using lead-free relays in leaded assembly process will not cause any
l
problems (compatible).
"LF" is marked on each outer and inner carton. (No marking on individual relays).
l
To avoid leaded relays (for lead-free sample, etc.) please consult with area sales office.
l
We will ship leaded relays as long as the leaded relay inventory exists.
l
Note: Cadmium was exempted from RoHS on October 2, 2005. (Amendment to Directive 2002/95/EC)
2. Recommended Lead Free Solder Profile
Recommended solder paste Sn-3.0Ag-0.5Cu.
l
Reflow Solder condtion
Flow Solder condtion:
Pre-heating:
maximum 120˚C
Soldering:
dip within 5 sec. at
260˚C soler bath
Solder by Soldering Iron:
Soldering Iron
Temperature: maximum 360˚C
Duration:

We highly recommend that you confirm your actual solder conditions
3. Moisture Sensitivity
Moisture Sensitivity Level standard is not applicable to electromechanical realys.
l
4. Tin Whisker
Dipped SnAgCu solder is known as low risk tin whisker. No considerable length whisker was found by our in
l
house test.
