ECF504-SC6 panel-mount RJ45 coupler from L-Com is not carried by Digikey. We do have a similar product, Digikey part EHRJ45P6S-ND to look at as a possible alternate.
We also list several options for CAT6 , shielded , plug to plug RJ45 cable assemblies available in different colors, lengths and environmental ratings.
The TechForum Cross Reference category is for parts that Digi-Key does not sell or parts that have gone obsolete. Our Engineers and Techs have reviewed the specifications for these parts and made a recommendation for a replacement. Please review the suggested part to ensure it will work for your application.
