Engineering Selection Recommendations

The Phoenix Contact 1862933 is the direct active equivalent for the obsolete 5449306. Selection is based on the following engineering criteria:

Product Status: The 1862933 maintains active product status, ensuring continued availability and manufacturer support. The 5449306 is obsolete and subject to supply discontinuation.

Compliance and Certifications: Both parts maintain UL94 V-0 flammability ratings and equivalent electrical performance (8A/320V IEC, 8A/300V UL). The 1862933 carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Electrical and Mechanical Compatibility: The 1862933 preserves all critical parameters: 10-position configuration, 4.60mm pitch, 270° free-hanging mounting, screw termination with M2 fasteners, and polyamide housing. Wire gauge range is expanded to 0.14-1.5mm², providing broader conductor compatibility.

Termination Enhancement: The 1862933 employs rising cage clamp termination technology with documented torque specifications (0.22-0.25 Nm), improving installation consistency compared to the standard screw termination of the 5449306.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1862933 directly replace the 5449306 in existing installations?

A: Yes. The 1862933 maintains identical electrical ratings (8A/320V IEC), mechanical configuration (10 positions, 4.60mm pitch, 270° mounting), and housing specifications (polyamide, UL94 V-0). Physical and electrical compatibility is confirmed across all critical parameters.

Q: What is the difference between screw termination and rising cage clamp termination?

A: Both are screw-based termination methods. The 1862933 uses rising cage clamp technology, which provides a spring-loaded contact mechanism that improves wire retention and reduces installation torque variation. Standard screw termination, used in the 5449306, requires manual screw tightening without spring assistance.

Q: Does the expanded wire gauge range (0.14-1.5mm²) of the 1862933 affect compatibility?

A: No. The expanded range is a superset of the original 5449306 specification (0.2-1.5mm²). All wire gauges compatible with the 5449306 are fully compatible with the 1862933. The lower limit extension to 0.14mm² provides additional flexibility for finer conductors without affecting existing applications.

Q: Are there packaging differences between the two parts?

A: The 5449306 packaging is not specified in available data. The 1862933 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: What is the significance of ROHS3 and REACH Unaffected status on the 1862933?

A: ROHS3 compliance indicates the part meets the latest Restriction of Hazardous Substances directive requirements. REACH Unaffected status confirms the part is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) restrictions. These certifications ensure regulatory compliance for current and future applications.

Q: Is the 1862933 available in the same green color as the 5449306?

A: Yes. Both parts are specified in green color, maintaining visual consistency in system installations.
