Phoenix Contact 1645765 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1645765 is a heavy duty connector base designed for box mount, side entry applications with M40 thread size and B24 form factor. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The part 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 1645765 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount, Side Entry configuration
• Size & Thread Compatibility: B24 form factor with M40 thread size
• Mechanical Dimensions: 144.00mm L × 57.00mm W × 84.00mm H
• Operating Temperature: -40°C to 125°C range
• Housing Material & Construction: Aluminum, die cast
• Regulatory Compliance: RoHS compliance required

The substitute part 1082593 meets all critical mechanical and electrical parameters while offering enhanced ingress protection (IP66/IP67) and improved environmental resistance features. Both parts share identical form factor, mounting interface, and thermal operating range, enabling direct functional replacement in applications where the enhanced protection rating is compatible with system requirements.

Engineering Selection Recommendations

The Phoenix Contact 1082593 is the direct substitute for the obsolete 1645765. Both connectors maintain identical mechanical interfaces, form factors, and thermal specifications. The 1082593 offers the following advantages:

• Active Product Status: Currently manufactured and supported by Phoenix Contact, ensuring long-term availability and supply chain continuity
• Enhanced Protection Rating: IP66/IP67 certification provides superior dust and water ingress protection compared to the IP65 rating of the original part
• Improved Compliance: ROHS3 compliance exceeds the RoHS compliance of the original specification
• Environmental Resistance: Includes salt water resistance and feed-through features for demanding applications
• REACH Compliance: Documented as REACH Unaffected, meeting current regulatory requirements

The substitute part is suitable for direct replacement in applications where the enhanced ingress protection rating is compatible with system design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1082593 directly replace the 1645765 in existing installations?

A: Yes. Both connectors share identical B24 form factor, M40 thread size, mechanical dimensions (144.00mm × 57.00mm × 84.00mm), and operating temperature range (-40°C to 125°C). The mounting interface and electrical characteristics are compatible for direct substitution.

Q: What is the primary difference between these two connectors?

A: The 1082593 provides enhanced ingress protection (IP66/IP67 versus IP65) and includes dual side entry capability with salt water resistance. Both maintain the same mechanical footprint and thermal specifications.

Q: Why is the 1645765 listed as obsolete?

A: The 1645765 has been discontinued by Phoenix Contact. The 1082593 represents the current active product line for this connector category and should be used for new designs and replacement applications.

Q: Are there any compatibility concerns when substituting the 1082593 for the 1645765?

A: No compatibility concerns exist for the core mechanical and electrical interfaces. The enhanced IP66/IP67 protection rating of the 1082593 is a superset of the IP65 specification, making it suitable for applications requiring equal or greater environmental protection.

Q: What is the difference between the packaging specifications?

A: The 1645765 original specification does not list packaging details. The 1082593 is supplied in bulk packaging. Verify packaging requirements with your procurement specifications.
