Phoenix Contact 1678431 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1678431 is a base-mount side entry heavy duty connector from the HEAVYCON® B series, designed for box mounting applications with PG29 thread size. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1678431 is determined by the following critical parameters:

• Connector Type & Style: Must be base-mount, side entry configuration
• Size Designation: B24 size class is mandatory for mechanical and electrical compatibility
• Physical Dimensions: 144.00mm x 57.00mm x 84.00mm envelope must be maintained
• Operating Temperature: -40°C to 125°C range must be supported
• Housing Material & Construction: Aluminum die-cast housing with equivalent structural properties
• Compliance & Certifications: ROHS3 compliance and equivalent regulatory status

The substitute part 1082605 qualifies as a functional equivalent based on these core parameters, with enhanced ingress protection and thread configuration options.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082605 serves as the active production equivalent to the obsolete 1678431. Both components share identical physical dimensions, B24 size classification, and operating temperature specifications. The 1082605 maintains ROHS3 compliance and equivalent regulatory status.

Key differences in the substitute include:

• Thread Configuration: The 1082605 features dual M40 threads versus the single PG29 thread on the 1678431, providing alternative mounting options
• Ingress Protection Enhancement: IP66/IP67 rating on the 1082605 exceeds the IP65 specification of the original part, offering improved dust and water resistance
• Product Status: The 1082605 is in active production, ensuring long-term availability and supply chain continuity

For applications requiring the exact PG29 thread specification, mechanical interface verification is necessary. The enhanced ingress protection of the substitute provides additional environmental sealing capability suitable for demanding industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1082605 directly replace the 1678431 in existing installations?

A: Mechanical compatibility is confirmed through identical physical dimensions and B24 size designation. Thread configuration differs (M40 dual versus PG29 single), requiring verification of mounting interface compatibility in the specific application.

Q: What is the significance of the IP66/IP67 rating on the substitute part?

A: The 1082605 provides enhanced ingress protection compared to the IP65 specification of the 1678431. IP66/IP67 rating indicates dust-tight and waterproof performance, suitable for more severe environmental conditions.

Q: Are there compliance differences between the two parts?

A: Both parts maintain ROHS3 compliance and equivalent regulatory status. No compliance degradation occurs with substitution.

Q: Why is the 1678431 listed as obsolete?

A: Product obsolescence reflects Phoenix Contact's transition to active production models. The 1082605 represents the current generation equivalent within the HEAVYCON® B series.

Q: What packaging considerations apply to the substitute part?

A: The 1082605 is supplied in bulk packaging, whereas the original part packaging specification was not provided. Verify packaging requirements for your procurement process.
