content: ^ Kind of what I thought.Except my first thought was something like:Shit, that thing must be good for 1000w or more...Edit:Anyway...You need to learn how to use Google.They are a current Vishay product.http://www.vishay.com/resistors-fixed/list/product-50018/http://www.vishay.com/docs/50018/rso.pdfAvailable at Mouser, except they don't appear to stock 1R5 - you will need to email them.http://nz.mouser.com/Passive-Components/Resistors/_/N-5g9n?Keyword=vishay+RSO&FS=True30X250 appears to be 350w

content: Hello,EdoNork: Wattage is 350WMr.B: I have been through the links that you have given. The second link is pdf but that pdf doesnt mention anything in detail about the Manufacturing date marking which in my case is CI. The Vishay data book also havent given Marking specifications in detail for RSO Series.Also I am looking for cross reference or equivalent part for the same.

content: The problem is that you are not trying to help yourself.It appears that you want a spoon fed solution. Most members here will not bother with that attitude.Why are you fixated on the manufacturing date?Why does it matter?If you can physically fit a different case style then just search for a 1R5 resistor that will do 350w or more.Have you tried a parametric search at one of the usual suppliers?Mouser...http://nz.mouser.com/Passive-Components/Resistors/_/N-5g9n?P=1z0x7ldZ1yz3wahZ1yz6b5tZ1yz52ozZ1yzvstcZ1z0wn8mDigikey...http://www.digikey.co.nz/product-search/en?pv1=1075&pv2=573&pv2=130&pv2=35&FV=fff40001%2Cfff80488&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25There are 400w and 500w options from Mouser...You can contact Vishay directly for a replacement... They are still making them...Sorry, but wake up...
