Phoenix Contact 1678402 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1678402 is a base-mounted side entry heavy duty connector from the HEAVYCON® B series, designed for box mount applications with PG29 thread size and IP65 ingress protection. This connector is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations. The part features aluminum die-cast housing with powder coating, dual locking clips on the base bottom, and operates across a wide temperature range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1678402 is determined by the following critical parameters:

• Connector Type & Style: Must be base-mounted, side entry configuration
• Size Designation: Must maintain B24 size compatibility
• Housing Material & Construction: Aluminum die-cast housing required
• Lock Mechanism: Dual locking clips on base bottom
• Operating Temperature: Must support -40°C to 125°C range
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The substitute part 1082605 qualifies as an equivalent based on matching connector type, size, housing material, lock mechanism, temperature range, and compliance certifications. The primary differences involve thread size (M40 vs. PG29) and enhanced ingress protection rating (IP66/IP67 vs. IP65), which represent functional improvements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082605 serves as the primary substitute for the obsolete 1678402 based on the following engineering criteria:

Compliance & Regulatory Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Product Lifecycle: The 1082605 maintains active product status, providing assured long-term availability and supply chain stability compared to the obsolete 1678402.

Mechanical Compatibility: Identical B24 size designation, housing material (aluminum die-cast), dimensions, and dual locking clip configuration ensure direct mechanical fit in existing mounting applications.

Environmental Protection Enhancement: The 1082605 provides IP66/IP67 ingress protection versus the IP65 rating of the original part, representing improved dust and water resistance without compromising existing system requirements.

Thread Interface Consideration: The transition from PG29 to M40 thread size requires verification of panel cutout and mounting hardware compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1082605 directly replace the 1678402 in existing installations?

A: Mechanical and electrical compatibility is established through matching connector type, B24 size, housing material, and operating temperature range. Thread size difference (M40 vs. PG29) requires confirmation that panel mounting hardware and cutout dimensions accommodate the substitute part.

Q: What is the significance of the IP66/IP67 rating upgrade in the 1082605?

A: The enhanced ingress protection rating indicates improved sealing against dust ingress and water jets (IP66) and temporary immersion (IP67) compared to the IP65 dust-tight and water-resistant specification of the original part. This represents a functional improvement suitable for applications requiring higher environmental protection.

Q: Are there inventory considerations between these parts?

A: The 1678402 shows 855 pieces in stock as new original inventory, while the 1082605 shows 789 pieces. Both are available in quantity, though the 1082605 represents the active product line for future procurement.

Q: Does the dual side entry configuration of the 1082605 affect compatibility?

A: The dual side entry designation indicates enhanced feed-through capability and salt water resistance features. This does not prevent single-entry applications; the part remains mechanically and electrically compatible with standard side entry mounting configurations.

Q: What compliance certifications apply to both parts?

A: Both the 1678402 and 1082605 maintain ROHS3 compliance and REACH unaffected status. ECCN classification is EAR99 for both parts, and HTSUS code 8538.90.8180 applies to both, ensuring consistent regulatory treatment in international trade and procurement scenarios.
