Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1082587 qualifies as a direct substitute for the 1646299 based on the following critical parameters:

Matching Parameters:

• Manufacturer: Phoenix Contact (same manufacturer ensures design compatibility)
• Connector Type: Base - Box Mount (identical functional form factor)
• Style: Side Entry (same entry configuration)
• Size: B16 (identical size designation)
• Thread Size: M32 (identical mechanical interface)
• Lock Location: Locking Clip (1) on Base Bottom (identical locking mechanism)
• Operating Temperature Range: -40°C to 125°C (identical thermal specification)
• Housing Material: Aluminum, Die Cast (identical material composition)
• Series: HEAVYCON® B family (same product family)

Enhanced Specifications: The 1082587 provides improved ingress protection (IP66/IP67 versus IP65) and includes salt water resistance, representing a performance upgrade while maintaining full mechanical and electrical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082587 is the direct functional equivalent for applications currently specified with the 1646299. Selection of the 1082587 is supported by:

• Product Status: The 1082587 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 1646299.
• Regulatory Compliance: The 1082587 meets ROHS3 compliance standards, representing current regulatory alignment. Both parts maintain EAR99 export classification and identical HTSUS coding (8538.90.8180).
• Environmental Protection: The enhanced IP66/IP67 rating of the 1082587 provides superior ingress protection in demanding environments while maintaining compatibility with IP65-specified applications.
• Mechanical Compatibility: Identical thread size (M32), locking mechanism, and housing material ensure direct mechanical interchangeability without modification to mounting structures or mating components.

Frequently Asked Questions (FAQ)

Q: Can the 1082587 directly replace the 1646299 in existing installations?

A: Yes. Both connectors share identical mechanical interfaces (M32 thread, B16 size, side entry configuration, and locking clip design). The 1082587 can be installed in any application originally specified for the 1646299 without modification to mounting hardware or mating connectors.

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 1082587's enhanced rating provides superior environmental protection in the same physical form factor.

Q: Why is the 1646299 listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions based on market demand, design evolution, or replacement by improved models. The 1082587 represents the current active equivalent within the HEAVYCON® B family.

Q: Are there dimensional differences between these connectors?

A: Dimensions are nearly identical. The 1646299 measures 117.00mm L × 57.00mm W × 84.00mm H, while the 1082587 measures 117.50mm L × 57.00mm W × 84.70mm H. These minimal variations (0.5mm length, 0.7mm height) do not affect mounting compatibility in standard applications.

Q: What does "Dual" mean in the 1082587 style designation?

A: The "Dual" designation indicates the connector accommodates dual M32 thread entries, providing flexibility for applications requiring multiple entry points while maintaining the same base footprint and locking mechanism.

Q: Are both connectors RoHS compliant?

A: Yes. The 1646299 is RoHS Compliant, and the 1082587 is ROHS3 Compliant. Both meet hazardous substance restrictions for electronic components. ROHS3 represents the current regulatory standard.
