Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1771985 is determined by strict alignment with the following critical parameters:

• Connector Type: Base - Box Mount configuration
• Style: Side Entry orientation
• Size: B24 form factor
• Thread Size: PG21 interface
• Housing Material: Aluminum, Die Cast construction
• Operating Temperature Range: -40°C to 125°C minimum capability
• Manufacturer: Phoenix Contact (series compatibility)

The substitute part 1412879 meets all these core requirements while representing an active product status within the HEAVYCON® EVO series, providing enhanced ingress protection and additional environmental resistance features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412879 serves as the direct functional equivalent for the obsolete 1771985 model. Both connectors maintain identical mechanical and electrical interface specifications: B24 size, PG21 thread, side entry configuration, and -40°C to 125°C operating range. The 1412879 represents an active product within the HEAVYCON® EVO series and carries ROHS3 compliance, exceeding the RoHS compliance level of the original part.

The 1412879 provides enhanced environmental protection through IP66/IP67/IP69K ingress protection ratings and salt water resistance features not present in the original specification. These enhancements do not compromise backward compatibility with existing mechanical mounting interfaces or electrical connection points.

For applications requiring the exact original specification without enhanced environmental features, the 1412879 remains the sole documented substitute meeting all core parameter requirements. Inventory availability is confirmed at 1059 pieces in new original condition.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1412879 directly replace the 1771985 in existing installations?

A: Yes. Both connectors share identical connector type (Base - Box Mount), style (Side Entry), size (B24), thread size (PG21), housing material (Aluminum, Die Cast), and operating temperature range (-40°C to 125°C). Mechanical mounting and electrical interface compatibility is maintained.

Q: What are the key differences between these two models?

A: The primary differences are product status and environmental protection. The 1771985 is obsolete; the 1412879 is active. The 1412879 includes IP66/IP67/IP69K ingress protection and salt water resistance. Both maintain identical core specifications for connector type, size, and thread interface.

Q: Does the enhanced ingress protection of the 1412879 affect compatibility?

A: No. The ingress protection enhancement is an additional feature that does not alter the mechanical or electrical interface specifications. The 1412879 maintains full backward compatibility with applications designed for the 1771985.

Q: Are there packaging differences between these parts?

A: The 1771985 packaging is not specified in available documentation. The 1412879 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What compliance certifications apply to the 1412879?

A: The 1412879 carries ROHS3 compliance, RoHS Unaffected REACH status, EAR99 export classification, and HTSUS code 8538.90.8180. Moisture Sensitivity Level is 1 (Unlimited).
