Phoenix Contact 1646489 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1646489 is a Heavy Duty Connector base unit designed for box mount, side entry applications with M20 thread size in the HEAVYCON® B series. 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 compatible substitute parts essential for ongoing system maintenance and new installations requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1646489 is determined by the following core parameters:

• Connector Type & Style: Must be Base - Box Mount, Side Entry configuration
• Size Designation: B10 size class
• Thread Size: M20 threading requirement
• Ingress Protection: IP65 minimum (higher ratings such as IP66, IP67, or IP69K are acceptable as they exceed the original specification)
• Operating Temperature: -40°C to 125°C range compatibility
• Housing Material: Aluminum, Die Cast construction
• Compliance: RoHS Compliant status

The substitute part 1412830 meets all core substitution criteria while offering enhanced ingress protection (IP66/IP67/IP69K) and additional features including salt water resistance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412830 is a direct functional substitute for the obsolete 1646489. Both connectors share identical core specifications: B10 size, M20 thread, side entry configuration, and aluminum die-cast housing. The substitute maintains full operating temperature compatibility (-40°C to 125°C) and RoHS compliance.

The 1412830 offers enhanced ingress protection (IP66/IP67/IP69K versus IP65), exceeding the original specification and providing additional environmental sealing capability. The substitute includes salt water resistance and feed-through features not present in the original design. As an active product in the HEAVYCON® EVO series, the 1412830 ensures long-term availability and supply chain continuity compared to the obsolete 1646489.

Selection of the 1412830 is appropriate for applications requiring equivalent or superior environmental protection within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 1412830 directly replace the 1646489 in existing installations?

A: Yes. Both connectors share identical connector type (Base - Box Mount), style (Side Entry), size (B10), and thread size (M20). The 1412830 maintains the same operating temperature range and housing material specifications.

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

A: The original 1646489 provides IP65 protection (dust tight, water resistant). The substitute 1412830 provides IP66/IP67/IP69K protection, which exceeds IP65 specifications and adds waterproof capability and salt water resistance.

Q: Are there dimensional differences between the two connectors?

A: The connectors share identical length (93.00mm) and width (52.00mm). The 1412830 height is 54.00mm compared to 52.00mm for the 1646489, a 2.00mm difference due to design improvements in the HEAVYCON® EVO series.

Q: Does the 1412830 maintain RoHS compliance?

A: Yes. The 1412830 is RoHS Compliant, matching the compliance status of the original 1646489.

Q: Why is the original 1646489 listed as obsolete?

A: The 1646489 has been superseded by the newer HEAVYCON® EVO series, represented by the 1412830, which offers enhanced environmental protection and additional features while maintaining core functional compatibility.

Q: What packaging is available for the substitute part?

A: The 1412830 is available in Bulk packaging, compared to the original part's standard packaging designation.
