Phoenix Contact 1646418 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1646418 is a heavy duty connector base designed for box mount, side entry applications with M32 thread size in the B10 configuration. This connector delivers IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The part is classified as obsolete, making identification of active equivalent models essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1646418 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount, Side Entry configuration
• Size Designation: B10 form factor
• Thread Size: M32 mechanical interface
• Operating Temperature: -40°C to 125°C minimum range
• Housing Material: Aluminum die cast construction
• Ingress Protection: IP65 minimum (higher ratings acceptable)
• Manufacturer: Phoenix Contact HEAVYCON® series

The substitute part 1082579 qualifies as a direct equivalent because it maintains all critical mechanical and electrical parameters while offering enhanced ingress protection (IP66/IP67) and additional features (feed through, salt water resistance).

Engineering Selection Recommendations

The Phoenix Contact 1082579 is the qualified substitute for the obsolete 1646418 model. Selection is based on:

• Product Status: The 1082579 maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance: Both parts meet RoHS requirements; the 1082579 achieves ROHS3 compliance with REACH unaffected status
• Mechanical Compatibility: Identical B10 size, M32 thread, and base mount configuration ensure direct mechanical fit
• Enhanced Performance: The 1082579 provides superior ingress protection (IP66/IP67 vs. IP65) and salt water resistance, making it suitable for equivalent or more demanding environments
• Thermal Range: Both parts operate across the identical -40°C to 125°C range

Frequently Asked Questions (FAQ)

Q: Can the 1082579 directly replace the 1646418 in existing installations?

A: Yes. Both connectors share identical mechanical interfaces (M32 thread, B10 size, side entry base mount configuration) and thermal operating ranges. The 1082579 provides equal or superior performance with enhanced ingress protection.

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

A: IP65 provides dust tight and water resistant protection. IP66/IP67 adds waterproof capability, offering protection against high-pressure water jets (IP66) and temporary immersion (IP67). The 1082579 is suitable for applications requiring higher environmental protection.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 1646418 measures 93.00mm L × 57.00mm W × 74.00mm H, while the 1082579 measures 92.00mm L × 52.00mm W × 74.50mm H. These differences do not affect mechanical compatibility in standard box mount applications.

Q: What does "Dual" mean in the 1082579 description?

A: The 1082579 features dual side entry capability, allowing connection from two sides. This does not prevent single-side operation and maintains full compatibility with single-entry applications.

Q: Is the 1082579 available in bulk packaging?

A: Yes. The 1082579 is supplied in bulk packaging with 829 pieces currently in stock, supporting high-volume procurement requirements.
