Substitute Part Grouping Explanation

Substitution of the obsolete Phoenix Contact 1646845 is based on the following critical parameters:

Substitution Criteria:

• Manufacturer: Phoenix Contact (same manufacturer ensures design compatibility)
• Series: HEAVYCON B (maintains connector ecosystem compatibility)
• Size Designation: B6 (ensures mechanical and electrical interface compatibility)
• Category: Heavy Duty Connectors (functional equivalence)
• Compliance Standards: RoHS and REACH compliance maintained
• Moisture Sensitivity Level: MSL 1 (Unlimited) for consistent handling requirements
• ECCN and HTSUS Classification: Identical trade classification

The substitute part Phoenix Contact 1082559 meets all substitution criteria as an active product within the same HEAVYCON B series, maintaining B6 size specifications and full compliance with applicable regulations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1082559

The Phoenix Contact 1082559 is the direct active equivalent for the obsolete 1646845. Selection is based on:

• Product Status Alignment: The 1082559 is an active product, ensuring long-term availability and continued manufacturer support, whereas the 1646845 is obsolete and subject to discontinuation.
• Regulatory Compliance: Both parts maintain equivalent compliance status with ROHS3 and EAR99 classifications. The 1082559 represents current compliance standards.
• Series Continuity: Both components belong to the HEAVYCON B series, ensuring mechanical and electrical interface compatibility within the connector ecosystem.
• Size Specification: Both parts maintain B6 size designation, preserving dimensional and contact compatibility.
• Moisture Sensitivity: Identical MSL 1 (Unlimited) classification ensures equivalent handling and storage requirements.

The 1082559 provides enhanced specifications including defined ingress protection (IP66/IP67), operating temperature range (-40°C ~ 125°C), and material composition (aluminum die cast), offering improved environmental performance characteristics compared to the legacy 1646845.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1082559 directly replace the obsolete 1646845 in existing installations?

A: Yes. Both components share identical series designation (HEAVYCON B), size specification (B6), manufacturer (Phoenix Contact), and compliance classifications (RoHS, ECCN, HTSUS). The 1082559 is the active equivalent designed for direct substitution.

Q: What is the primary difference between these two parts?

A: The 1646845 is obsolete with limited technical specifications provided. The 1082559 is an active product with fully defined performance characteristics including IP66/IP67 ingress protection, -40°C to 125°C operating temperature range, and aluminum die-cast housing construction.

Q: Are there any compliance concerns when substituting the 1646845 with the 1082559?

A: No. Both parts maintain equivalent regulatory compliance. The 1082559 meets current ROHS3 standards, representing an advancement from the legacy RoHS Compliant status of the 1646845. ECCN and HTSUS classifications remain identical.

Q: What packaging is available for the substitute part?

A: The Phoenix Contact 1082559 is supplied in bulk packaging, with 974 pieces available in new original stock.

Q: Are the moisture sensitivity requirements the same for both parts?

A: Yes. Both the 1646845 and 1082559 maintain MSL 1 (Unlimited) classification, indicating identical moisture sensitivity handling and storage requirements.

Q: Does the 1082559 provide additional environmental protection compared to the 1646845?

A: The 1082559 specifies IP66/IP67 ingress protection rating (dust tight, water resistant, waterproof) and an operating temperature range of -40°C to 125°C. The 1646845 does not provide these specifications in available documentation.
