Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1421127 directly replace the 1406340 in existing installations?

A: Yes. Both connectors maintain identical 8p8c RJ45 plug configuration, shielded design, IDC termination, and support for 22-23 AWG round cable. Mechanical and electrical interfaces are fully compatible.

Q: What is the difference in cable ratings between Cat5e and Cat5?

A: The 1406340 is rated for Cat5e, while the 1421127 is rated for Cat5. Both support standard Ethernet applications with 22-23 AWG wire gauge and identical physical dimensions. The Cat5e rating of the original part represents a higher performance specification; the Cat5 rating of the substitute remains suitable for standard Ethernet installations.

Q: Are there packaging differences between these parts?

A: The 1406340 packaging is not specified in available documentation. The 1421127 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Does the gold contact finish of the 1421127 provide advantages over the unspecified finish of the 1406340?

A: Gold plating improves contact resistance stability and corrosion resistance. For applications requiring enhanced signal integrity or extended service life in corrosive environments, the gold-plated contacts of the 1421127 provide measurable benefits.

Q: Are both parts RoHS compliant?

A: Yes. The 1406340 is RoHS Compliant. The 1421127 is ROHS3 Compliant, representing current regulatory certification standards.
