Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1423976 directly replace the 1582166 in existing installations?

A: Yes. The 1423976 maintains identical mechanical dimensions, electrical ratings, and environmental protection specifications. No modifications to panel mounting, cable assemblies, or system design are required for substitution.

Q: What is the primary reason for substituting the 1582166?

A: The 1582166 is obsolete. The 1423976 provides an active, functionally equivalent alternative with identical specifications and assured long-term availability.

Q: Are the IDC termination specifications identical between both connectors?

A: Yes. Both connectors utilize IDC termination with identical cable opening range (6.00mm to 10.00mm) and contact specifications.

Q: Do both connectors meet the same environmental protection standards?

A: Yes. Both connectors are rated IP66/IP68/IP69K, providing equivalent dust-tight and waterproof protection for industrial applications.

Q: Are there differences in voltage or shielding specifications?

A: The 1423976 specifies a 690V voltage rating and unshielded configuration. The 1582166 does not specify these parameters. For applications requiring specific voltage or shielding characteristics, verify that the 1423976 specifications align with system requirements.

Q: What is the packaging difference between these connectors?

A: The 1582166 packaging is not specified. The 1423976 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Are both connectors RoHS compliant?

A: Yes. Both the 1582166 and 1423976 are RoHS compliant with UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level.
