Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1559770 is determined by strict equivalence across the following critical parameters:

Connector Configuration: Receptacle with female sockets, 4-position, M12-4 shell size
Termination Method: Spring-cage contact system
Electrical Performance: 4A current rating, 48VAC/60VDC voltage rating
Environmental Protection: IP67 ingress protection rating
Mechanical Compatibility: Free hanging in-line mounting, threaded or push-twist fastening
Material Specifications: Shielded construction with nickel-plated brass or zinc die-cast shell, gold-plated copper-tin contacts
Temperature Range: -40°C to 85°C operating capability

The Phoenix Contact 1559770 has one direct substitute: 1424700 (SACC series). This substitute maintains functional and electrical equivalence while offering active product status and enhanced ingress protection (IP65/IP67).

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1424700

The 1424700 is the direct equivalent for the obsolete 1559770. Selection of this substitute is based on:

Product Status: The 1424700 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the 1559770 is obsolete.
Functional Equivalence: Both connectors maintain identical electrical ratings (4A, 48VAC/60VDC), mechanical configuration (M12-4, 4-position, spring-cage), and environmental protection (IP67).
Compliance: Both components are RoHS compliant. The 1424700 carries ROHS3 certification, meeting current regulatory requirements.
Material Compatibility: While the 1559770 uses brass shell material and the 1424700 uses zinc die-cast, both are nickel-plated and maintain equivalent corrosion resistance and electrical performance.
Fastening Difference: The 1559770 uses threaded fastening while the 1424700 uses push-twist fastening. Both methods provide secure mechanical coupling suitable for M12-4 applications.

The 1424700 is suitable for direct substitution in applications requiring M12-4 circular connector receptacles with spring-cage termination and IP67 protection.

Frequently Asked Questions (FAQ)

Q: Can the 1424700 directly replace the 1559770 in existing installations?

A: Yes. Both connectors share identical electrical specifications (4A, 48VAC/60VDC), mechanical configuration (M12-4, 4-position, spring-cage), and environmental protection (IP67). The primary difference is fastening type: threaded versus push-twist. Both fastening methods provide equivalent mechanical security for M12-4 applications.

Q: What is the difference between IP65 and IP67 ratings?

A: The 1424700 is rated IP65/IP67, while the 1559770 is rated IP67. IP65 provides dust-tight and water-resistant protection; IP67 provides dust-tight and waterproof protection (temporary immersion). The 1424700 meets or exceeds the protection level of the original component.

Q: Are there any compliance differences between these connectors?

A: Both connectors are RoHS compliant. The 1559770 carries standard RoHS certification, while the 1424700 carries ROHS3 certification, which reflects current regulatory standards. Both meet environmental compliance requirements.

Q: What is the significance of the series designation (CC Link vs. SACC)?

A: The series designation indicates the product line within Phoenix Contact's connector portfolio. The 1559770 belongs to the CC Link series (now obsolete), while the 1424700 belongs to the SACC series (active). The series change reflects product line evolution; however, the connectors maintain functional equivalence for M12-4 applications.

Q: Are the spring-cage termination systems identical between these parts?

A: Yes. Both connectors use spring-cage termination, which provides consistent contact pressure and secure wire retention. The termination method is functionally equivalent across both components.

Q: What packaging options are available?

A: The 1559770 is supplied in standard packaging, while the 1424700 is supplied in bulk packaging. Bulk packaging typically offers cost advantages for high-volume applications.
