Supplier advises August 2015:

Product Change Notice 
A change has been made to the housing of most of the 6200N 
series fans. 

Reason for change 
Continuous product improvement 

Description 
Extended cable exit at the flange area 
Lip at the strut / cable channel 

Effect 
Improved and easier assembly of the harness as well as improved 
position of the lead wire in the strut of the fan housing 

This is a running change, so the new and improved design will 
ship as stock of the current design depletes.  Please note that 
depending on stock levels, you may receive a mixed shipment of 
both the current and new designs. 

Please contact a Mouser Technical Sales Representative for further 
information.
