Phoenix Contact 1678266 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1678266 is a Heavy Duty Connector hood coupling assembly designed for D15 sized connectors with bottom entry configuration and PG16 thread size. This component provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1678266 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector Type: Hood - Coupling
• Size: D15
• Style: Bottom Entry
• Thread Size: PG16
• Series: HEAVYCON® D
• Housing Material: Aluminum, Die Cast
• Operating Temperature Range: -40°C to 125°C (minimum)

Functional Enhancement Parameters:

• Ingress Protection rating (equal or superior to IP65)
• RoHS Compliance status
• Cable-to-Cable configuration capability

The substitute part 1424360 maintains all core compatibility parameters while providing enhanced ingress protection (IP66/IP67 versus IP65) and additional environmental resistance features (salt water resistant). Both parts share identical connector sizing, thread specifications, and thermal operating ranges, establishing direct functional equivalence within the HEAVYCON® D series.

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1424360

Part 1424360 is the direct functional equivalent for applications currently specified with 1678266. Selection rationale:

• Maintains all mechanical and electrical interface specifications (D15 size, PG16 thread, bottom entry configuration)
• Operates within identical temperature range (-40°C to 125°C)
• Provides enhanced environmental protection (IP66/IP67 versus IP65), suitable for applications requiring superior ingress protection
• Active product status ensures ongoing availability and supply chain continuity
• Identical locking mechanism and housing material composition
• Includes salt water resistance feature for marine or corrosive environment applications

The transition from 1678266 to 1424360 introduces no compatibility issues with existing D15 connector systems within the HEAVYCON® D series. The enhanced ingress protection rating represents a functional improvement rather than a limitation.

Frequently Asked Questions (FAQ)

Q: Can 1424360 directly replace 1678266 in existing installations?

A: Yes. Both parts share identical D15 connector sizing, PG16 thread specifications, bottom entry configuration, and operating temperature ranges. The mechanical and electrical interfaces are fully compatible within HEAVYCON® D series applications.

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/IP67 extends protection to high-pressure water jets (IP66) and temporary immersion (IP67). Part 1424360 offers superior environmental sealing suitable for more demanding applications.

Q: Why is 1678266 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Phoenix Contact. Part 1424360 is the active production equivalent within the HEAVYCON® D series, ensuring long-term availability for new designs and replacement requirements.

Q: Are there packaging differences between these parts?

A: 1678266 packaging information is not specified in available data. 1424360 is supplied in bulk packaging. Confirm packaging requirements with your procurement department for order quantities and handling specifications.

Q: Do both parts meet RoHS compliance requirements?

A: 1678266 is confirmed RoHS compliant. RoHS status for 1424360 is not specified in the provided technical data. Consult Phoenix Contact documentation or your supplier for complete RoHS certification details if regulatory compliance is required.
