Procurement Notes

Verify the specific ordering code against the official Phoenix Contact catalog to ensure compatibility with existing assembly lines. Confirm that the spring-cage mechanism matches the wire gauge requirements of your specific application. Check for any updated safety certifications relevant to your region before finalizing procurement decisions.

Selection Notes

Select this component when space constraints require a low-profile terminal solution with high current carrying capacity. Ensure the operating environment temperature does not exceed the specified limits for optimal performance. Consider the mating connector or plug type if pre-wired solutions are preferred for faster assembly processes.

Part Context

This terminal block belongs to the UK series of PCB connectors, widely used in European industrial standards. It complements other components in the same family, such as bridging elements and marking systems, allowing for modular expansion of control circuits while maintaining consistent mechanical and electrical characteristics across the system.

Replacement Considerations

Direct substitutes must match the 5.08 mm pitch, 12 A current rating, and spring-cage interface. Verify pin count and housing dimensions to ensure physical compatibility. Cross-reference with Phoenix Contact's replacement guide for equivalent series upgrades or legacy part transitions.
