SSR Ordering Information Change Circular

Dear Sir or Madam,

Firstly, we want to extend our sincere appreciation for your great support to Hongfa SSR department. In order to make the ordering and using of Hongfa solid-state relays more convenient, Hongfa would like to make an announcement on the adjustment of the ordering information as following: All Hongfa solid-state relays are RoHS compliant, and special number of 555 is used to distinguish RoHS compliant products from lead-contained products. Please remember to add 555 after the former ordering number for RoHS compliant products. For example: HFS15/D-240A25Z(555). Furthermore, Hongfa should inform customer to increase soldering temperature of PCB mounting for RoHS compliant solid-state relays. The recommended wave-soldering temperature for lead-free products is 240 to 260℃/ 3 to 4 Sec., while the recommended reflow soldering temperature is 230 to 250℃ / within 30 Sec. If there is any problem, please contact Hongfa for technical support. New ordering number for Hongfa solid-state relays will be used from now on. In order to ensure that customers can be familiar with new ordering numbers, both ordering number are listed in our catalogues, and the one in parenthesis mark is the old ordering number before modification. Following chart indicates the cross reference of new ordering number and old ordering number used before modification.
