Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1645723 is determined by the following critical parameters that must remain constant or improve:

• Connector Type & Style: Must remain Base - Box Mount, Side Entry configuration
• Size Designation: B24 size compatibility is mandatory
• Thread Size: M40 mounting thread must be maintained
• Housing Material: Aluminum die cast construction ensures mechanical and thermal compatibility
• Operating Temperature: -40°C to 125°C range must be supported
• Ingress Protection: Minimum IP65 rating; higher ratings (IP66/IP67) represent functional improvements

The substitute part Phoenix Contact 1082605 maintains all critical mechanical and electrical parameters while offering enhanced ingress protection (IP66/IP67) and active product status, making it a direct functional equivalent with improved environmental sealing capabilities.

Engineering Selection Recommendations

The Phoenix Contact 1082605 is the direct substitute for the obsolete 1645723 connector base. Selection of the 1082605 is supported by the following engineering factors:

• Product Status: The 1082605 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity
• Compliance: Both parts maintain RoHS compliance; the 1082605 achieves ROHS3 compliance, representing current regulatory alignment
• Environmental Protection: The 1082605 provides enhanced ingress protection at IP66/IP67 versus the original IP65 rating, offering improved performance in harsh environments without compromising mechanical compatibility
• Physical Compatibility: Identical dimensions and M40 thread sizing ensure direct mechanical fit in existing mounting configurations
• Thermal Performance: Maintained operating temperature range of -40°C to 125°C ensures thermal equivalence across industrial applications

Frequently Asked Questions (FAQ)

Q: Can the 1082605 be used as a direct replacement for the 1645723 in existing installations?

A: Yes. The 1082605 maintains identical mechanical dimensions (144.00mm x 57.00mm x 84.00mm), M40 thread size, B24 connector size, and aluminum die cast housing. The connector base will mount directly without modification to existing enclosures or panel configurations.

Q: What is the difference between IP65 and IP66/IP67 ratings?

A: IP65 provides dust-tight and water-resistant protection against low-pressure water jets. IP66 extends protection to high-pressure water jets, while IP67 adds temporary immersion capability. The 1082605 offers enhanced environmental sealing suitable for more demanding applications.

Q: Are there any electrical or functional differences between these parts?

A: No electrical differences exist. Both parts function identically as base connector housings. The 1082605 designation includes "Dual" in its style specification, indicating dual M40 entry capability, which represents a functional enhancement while maintaining backward compatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status ensures continued manufacturing, technical support, and supply availability. The 1082605 will remain available for procurement and integration into new designs, eliminating supply risk associated with obsolete components.

Q: Are both parts RoHS compliant?

A: Yes. The 1645723 is RoHS Compliant, and the 1082605 is ROHS3 Compliant. ROHS3 represents the current regulatory standard, ensuring the substitute part meets contemporary environmental and material restriction requirements.
