Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1674176 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount, Side Entry configuration
• Size Designation: Must be B24 to ensure mechanical and electrical compatibility
• Thread Size: Must be PG21 for proper mounting interface
• Lock Mechanism: Must feature Locking Clip (2) on Base Bottom
• Housing Material: Must be Aluminum, Die Cast
• Operating Temperature: Must support -40°C ~ 125°C range
• Ingress Protection: Must meet or exceed IP65 rating

The substitute part 1412875 satisfies all critical substitution parameters. It maintains identical connector type, size, thread size, lock location, housing material, and operating temperature range. The substitute provides enhanced ingress protection (IP66/IP67/IP69K versus IP65) and belongs to the HEAVYCON® EVO series, representing an active product with improved environmental resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412875 is the direct substitute for the obsolete 1674176. Both components share identical mechanical interfaces (B24 size, PG21 thread, side entry configuration) and thermal operating range (-40°C ~ 125°C). The substitute maintains full compatibility with existing mounting and connector systems designed for the original part.

The 1412875 represents an active product within Phoenix Contact's current HEAVYCON® EVO product line, ensuring long-term availability and supply chain continuity. The enhanced ingress protection rating (IP66/IP67/IP69K versus IP65) provides superior environmental sealing without compromising mechanical or electrical compatibility. Both components meet RoHS compliance requirements, with the substitute meeting the more recent ROHS3 standard.

Frequently Asked Questions (FAQ)

Q: Can the 1412875 directly replace the 1674176 in existing installations?

A: Yes. Both components share identical connector type, size designation (B24), thread size (PG21), lock mechanism, housing material, and operating temperature range. The mechanical and electrical interfaces are fully compatible.

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

A: The 1674176 provides IP65 protection (dust tight, water resistant). The 1412875 provides IP66/IP67/IP69K protection (dust tight, water resistant, waterproof). The substitute offers enhanced environmental sealing suitable for more demanding applications.

Q: Why is the 1674176 listed as obsolete?

A: The 1674176 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series. Phoenix Contact has transitioned production to the newer 1412875 (HEAVYCON® EVO) to provide improved performance and compliance standards.

Q: Are there any dimensional differences between these parts?

A: Both components share identical length (5.669" / 144.00mm) and width (2.244" / 57.00mm). Height differs slightly: 1674176 is 2.638" (67.00mm) versus 1412875 at 2.677" (68.00mm). This minimal difference does not affect standard mounting applications.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant. The 1674176 meets RoHS requirements, while the 1412875 meets the more recent ROHS3 standard. Both carry ECCN EAR99 classification and HTSUS code 8538.90.8180.
