Phoenix Contact 1645192 Heavy Duty Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1645192 is a Heavy Duty Connector hood assembly designed for top entry applications with M25 thread size and D50 form factor. 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 system maintenance, repair, and component sourcing in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1645192 is determined by the following critical parameters:

• Connector Type & Style: Must be Hood connector with Top Entry configuration
• Size Designation: Must be D50 form factor
• Thread Size: Must be M25
• Series Compatibility: Must belong to HEAVYCON® D series
• Lock Mechanism: Must feature Locking Clip (2) on Base Bottom
• Operating Temperature: Must support -40°C to 125°C range
• Housing Material: Must be Aluminum, Die Cast
• Ingress Protection: Must meet or exceed IP65 rating

The substitute part 1645192 meets all critical substitution criteria. While it offers enhanced ingress protection (IP66/IP67 versus IP65) and includes salt water resistance features, the core mechanical and electrical compatibility parameters remain aligned with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1424408 is a direct substitute for the obsolete 1645192. Both components share identical mechanical interfaces (D50 size, M25 thread, top entry configuration) and thermal operating ranges. The 1424408 maintains full compatibility with existing installations designed for the 1645192.

The 1424408 provides enhanced environmental protection through IP66/IP67 rating and salt water resistance, representing a performance upgrade over the original IP65 specification. This upgrade does not introduce incompatibility; rather, it extends the connector's suitability to more demanding environmental conditions while maintaining backward compatibility with the original application requirements.

The 1424408 holds Active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete 1645192.

Frequently Asked Questions (FAQ)

Q: Can the 1424408 directly replace the 1645192 in existing installations?

A: Yes. Both connectors share identical mechanical form factors (D50, M25 thread), mounting configurations (top entry, locking clips on base bottom), and thermal operating ranges (-40°C to 125°C). The 1424408 is mechanically and functionally compatible with all applications designed for the 1645192.

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

A: The 1645192 provides IP65 protection (dust tight, water resistant). The 1424408 provides IP66/IP67 protection (dust tight, water resistant, waterproof). The enhanced rating of the 1424408 does not reduce compatibility; it extends environmental protection capabilities.

Q: Does the 1424408 include additional features?

A: The 1424408 includes salt water resistance as an additional feature. This enhancement is compatible with all applications requiring the original 1645192 specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1645192 and 1424408 are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the availability status of these parts?

A: The 1645192 is obsolete with no active manufacturing. The 1424408 is Active with current production support, ensuring reliable sourcing for new installations and replacements.

Q: Are there any dimensional differences between these connectors?

A: The 1645192 measures 3.228" L × 2.205" W × 2.992" H (82.00mm × 56.00mm × 76.00mm). The 1424408 measures 3.228" L × 2.205" W × 3.150" H (82.00mm × 56.00mm × 80.00mm). The height difference of 4.00mm does not affect mechanical compatibility or mounting interfaces.
