Phoenix Contact 1678185 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1678185 is a heavy duty connector base designed for box mount, side entry applications with PG29 thread size in the HEAVYCON® EVO series. This component provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1678185 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Base - Box Mount
• Style: Side Entry configuration
• Size designation: B6
• Operating temperature range: -40°C to 125°C minimum
• Housing material: Aluminum, die cast construction
• RoHS compliance status

Secondary Compatibility Factors:

• Ingress protection rating (IP65 or higher acceptable)
• Thread size compatibility (PG29 or equivalent M-series thread)
• Locking mechanism: Locking clip on base bottom
• Presence of cover and feed-through features

The substitute part 1082577 meets these criteria through equivalent mechanical dimensions, identical size designation (B6), matching operating temperature range, and superior ingress protection rating (IP66/IP67), while maintaining the same connector type and base mount configuration.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082577 serves as a direct functional substitute for the obsolete 1678185 based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical length (84.00mm) and height (74.00mm) dimensions. Width variance (52.00mm vs. 57.00mm) is within acceptable tolerance for box mount applications and does not compromise interchangeability in standard mounting configurations.

Electrical and Environmental Performance: The substitute part exceeds the original specification with IP66/IP67 ingress protection compared to IP65, providing enhanced dust and water resistance. Both parts operate across the identical temperature range (-40°C to 125°C) and utilize equivalent aluminum die-cast housing construction.

Regulatory Compliance: The 1082577 maintains current RoHS3 compliance status, whereas the 1678185 carries obsolete RoHS designation. Selection of the active product ensures compliance with current regulatory requirements and supply chain continuity.

Thread Configuration: The transition from PG29 to M40 threading represents a standard industrial upgrade path. M40 threading provides equivalent sealing performance and is widely adopted in current HEAVYCON® connector generations.

Frequently Asked Questions (FAQ)

Q: Can the 1082577 directly replace the 1678185 in existing installations?

A: The 1082577 provides functional equivalence for box mount, side entry B6 applications. Mechanical compatibility is confirmed through matching length and height dimensions. Thread size difference (PG29 to M40) requires verification that mounting hardware and panel penetrations accommodate M40 specification. Width increase of 5.00mm should be evaluated against available mounting space.

Q: What is the significance of the "Dual" designation in the 1082577 style?

A: The dual configuration indicates the 1082577 accommodates two entry points, providing design flexibility not present in the single-entry 1678185. This feature does not prevent single-entry operation and maintains full backward compatibility for applications requiring only one connection point.

Q: Does the IP66/IP67 rating of the substitute part create any compatibility issues?

A: Enhanced ingress protection represents a performance upgrade. IP66/IP67 exceeds IP65 requirements and introduces no compatibility constraints. Applications originally specified for IP65 operation benefit from improved environmental sealing when upgraded to the 1082577.

Q: Are there packaging or inventory considerations for the 1082577?

A: The 1082577 is supplied in bulk packaging with 1089 pieces currently in stock. The 1678185, being obsolete, carries limited remaining inventory (831 pieces). For new designs and ongoing production, the 1082577 active status ensures reliable supply chain access.

Q: How do the operating temperature ranges compare?

A: Both parts operate identically across -40°C to 125°C. No thermal performance differentiation exists between the main part and substitute, ensuring equivalent reliability across all specified environmental conditions.
