How to decipher a Thermalloy origin part number?
Aavid Thermalloy features a variety of Thermalloy origin standard products that consist of a different part
number sequence than the standard Aavid 12 digit part numbering system. In most cases, digits 1 through
4, designate the basic model number of the heat sink. Digits 5-6, designate the finish of the heat sink. Digits
6-13 can designate any number of different options that come with a specific model number. (Please refer
to Option Index D on page 85 to see Aavid Thermalloy‘s offerings per base number.)
To order most Thermalloy origin heat sinks you must use the basic part numbering system below:
A = Model Number
B = Finish
C = Productivity Enhancement (if applicable)
D = Second Productivity Enhancement (if applicable)
E = RoHS Compliant Suffix
