Structured cabling components (cable, connectors, panels, etc) are usually certified to a certain level of performance. The EIA/TIA sets the specifications.
The current popular spec is Category 5. TO keep Category five, EVERY component (cable, connector, panels, outlets) must be certified Category 5. The current higest spec is Category six...harder to find, more expensive, but likely to have "longer legs" than the Cat 5 stuff of today.
The other thing you have to watch for is whether it's 568A or 568B....for panels & outlets, both oughta be the same spec (568a or b). How you position the pairs in the connector is also a spec...the cable designers expect the colors to be in a certain sequence...failing to follow the right sequence will (might) blow the cable spec too.
That's it, in a nutshell. Keep yer "A's" & "B's" the same and you should be good (kinda like Geranimals....).
Good Luck
