Phoenix Contact 1645655 Heavy Duty Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1645655 is a base-mount side entry heavy duty connector from the HEAVYCON® B series, designed for M32 thread applications with B16 size configuration. 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1645655 is determined by the following critical parameters:

• Connector Type & Style: Must be base-mount, side entry configuration
• Size Designation: B16 size class
• Thread Interface: M32 thread size
• Ingress Protection: Minimum IP65 rating (equal or higher protection level acceptable)
• Operating Temperature: -40°C to 125°C range
• Housing Material: Aluminum die cast construction
• RoHS Compliance: Required for regulatory alignment

The substitute part 1412850 meets all substitution criteria while offering enhanced specifications in ingress protection and locking mechanism design.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412850 is the direct substitute for the obsolete 1645655 model. Both connectors maintain identical core specifications for connector type, size designation, thread interface, and operating temperature range. The 1412850 is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute part provides enhanced ingress protection (IP66/IP67/IP69K versus IP65), meeting or exceeding the environmental sealing requirements of the original design. Both components maintain RoHS compliance and aluminum die cast housing construction. The 1412850 incorporates dual locking clips on the hood assembly and includes salt water resistance features, representing a design evolution within the HEAVYCON® product family.

Frequently Asked Questions (FAQ)

Q: Can the 1412850 directly replace the 1645655 in existing installations?

A: Yes. Both connectors share identical connector type, side entry style, B16 size, M32 thread interface, and operating temperature specifications. The 1412850 provides equal or superior environmental protection and is mechanically compatible for box-mount applications.

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

A: The 1645655 provides IP65 protection (dust tight, water resistant). The 1412850 provides IP66/IP67/IP69K protection (dust tight, water resistant, and waterproof). The higher rating indicates enhanced sealing performance suitable for more demanding environmental conditions.

Q: Are there packaging differences between these parts?

A: The 1645655 is supplied in standard packaging. The 1412850 is supplied in bulk packaging. Packaging format does not affect connector functionality or mechanical compatibility.

Q: Why is the 1645655 listed as obsolete?

A: The 1645655 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412850). Phoenix Contact has transitioned production to the newer EVO platform, which incorporates design improvements including enhanced locking mechanisms and expanded environmental protection ratings.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1645655 and 1412850 are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.
