Phoenix Contact 1674118 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1674118 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG21 thread size and B24 connector size. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -40°C to 125°C. The unit features a gray aluminum die-cast housing with powder coating and includes a cover with dual locking clips on the hood.

The 1674118 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1674118 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B24 to ensure mechanical and electrical compatibility
• Thread Size: Must be PG21 for proper mounting interface
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Housing Material: Aluminum die cast construction maintains thermal and mechanical properties
• Ingress Protection: Must meet or exceed IP65 specification

The substitute part 1412871 satisfies all mandatory substitution criteria. It maintains identical connector type, style, size, and thread size specifications. The substitute operates within the same temperature range and uses the same housing material. The ingress protection rating of IP66/IP67/IP69K exceeds the original IP65 requirement, providing enhanced environmental sealing.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412871 is the direct substitute for the obsolete 1674118. Both parts maintain identical mechanical and electrical specifications for connector type, size, thread interface, and operating temperature range.

The 1412871 offers enhanced environmental protection with IP66/IP67/IP69K ingress rating compared to the original IP65 specification. This upgrade provides superior dust and water sealing without compromising mechanical compatibility. The substitute includes additional features such as feed-through capability and salt water resistance, which extend application suitability without affecting core connector function.

The 1412871 carries active product status with RoHS compliance, ensuring long-term availability and regulatory alignment. Selection of the 1412871 eliminates obsolescence risk while maintaining full compatibility with existing B24 PG21 connector systems.

Frequently Asked Questions (FAQ)

Q: Can the 1412871 directly replace the 1674118 in existing installations?

A: Yes. Both connectors share identical specifications for connector type (Base - Box Mount), style (Side Entry), size (B24), thread size (PG21), operating temperature range (-40°C to 125°C), and housing material (aluminum die cast). The mechanical and electrical interfaces are fully compatible.

Q: What is the difference in ingress protection between these parts?

A: The original 1674118 provides IP65 protection (dust tight, water resistant). The substitute 1412871 provides IP66/IP67/IP69K protection (dust tight, water resistant, waterproof). The enhanced rating offers superior environmental sealing and is suitable for more demanding applications without affecting compatibility.

Q: Why is the 1674118 listed as obsolete?

A: The 1674118 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412871). Phoenix Contact has transitioned production to the newer EVO platform, which provides improved environmental protection and additional features.

Q: Are there packaging differences between these parts?

A: The 1674118 was supplied with standard packaging. The 1412871 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet RoHS compliance?

A: Yes. The 1674118 is ROHS3 compliant. The 1412871 is RoHS compliant. Both meet current regulatory requirements for hazardous substance restrictions.
