Phoenix Contact 1642564 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1642564 is a Heavy Duty Connector Hood for top entry applications with M25 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -40°C to 100°C. The part is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1642564 is determined by the following critical parameters that must remain consistent:

• Connector Type & Style: Hood, Top Entry configuration
• Size Designation: B16
• Thread Size: M25
• Series Compatibility: HEAVYCON® B
• Lock Mechanism: Locking Clip (2) on Base Bottom
• Housing Material: Aluminum, Die Cast

The substitute part 1412721 maintains all these core mechanical and functional parameters. The primary differences are enhanced ingress protection rating (IP66/IP67/IP69K versus IP65), extended operating temperature range (-40°C to 125°C versus -40°C to 100°C), and improved environmental resistance (salt water resistant). These differences represent functional improvements rather than incompatibilities, making 1412721 a direct substitute for 1642564 in applications requiring equivalent or superior environmental protection.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412721 is the direct substitute for the obsolete 1642564. Both parts share identical mechanical interfaces (B16 size, M25 thread, top entry hood configuration, and locking clip mechanism), ensuring drop-in compatibility in existing installations.

The 1412721 is recommended for all new designs and replacement applications because it is currently in active production status with full inventory availability. The enhanced ingress protection rating (IP66/IP67/IP69K) and extended operating temperature range (-40°C to 125°C) provide superior environmental performance compared to the original specification. Both parts maintain equivalent RoHS compliance standards and are manufactured from identical housing materials.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1412721 directly replace 1642564 in existing installations?

A: Yes. Both connectors share identical mechanical specifications: B16 size, M25 thread, top entry hood style, and locking clip configuration. Physical mounting and mating interfaces are compatible.

Q: What are the key differences between these two parts?

A: The 1412721 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65), extended operating temperature range (125°C maximum versus 100°C), and salt water resistance. The 1642564 is obsolete; the 1412721 is in active production.

Q: Are there any compatibility concerns with the dimensional differences?

A: The parts have minor dimensional variations in width and height (1.732" W x 2.362" H for 1412721 versus 1.693" W x 2.992" H for 1642564). These differences do not affect mechanical compatibility or mounting interfaces, as the critical M25 thread and B16 size specifications remain identical.

Q: Which part should be specified for new designs?

A: Specify Phoenix Contact 1412721. It is in active production, offers superior environmental protection, and maintains full mechanical compatibility with applications originally designed for the 1642564.

Q: Are both parts RoHS compliant?

A: Yes. The 1642564 is RoHS Compliant; the 1412721 is ROHS3 Compliant, representing current regulatory compliance standards.
