Phoenix Contact 1672851 Heavy Duty Connector Hood - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1672851 is a heavy duty connector hood designed for side entry applications with D25 size and PG16 thread configuration. This component provides IP65 ingress protection (dust tight, water resistant) and operates across a wide temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations. The HEAVYCON® D series construction utilizes die-cast aluminum with powder coating for durability in industrial environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1672851 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type: Hood
• Style: Side entry configuration
• Size designation: D25
• Thread size: PG16
• Series compatibility: HEAVYCON® D
• Housing material: Aluminum, die cast
• Lock mechanism: Locking clip on base bottom
• Operating temperature range: -40°C to 125°C minimum
• RoHS compliance status

Secondary Compatibility Factors:

• Ingress protection rating (minimum IP65 or higher)
• Housing color (gray)
• ECCN and HTSUS classifications

The substitute part 1424379 meets all primary criteria and exceeds the ingress protection specification, making it a valid functional equivalent for applications requiring this connector type.

Engineering Selection Recommendations

The Phoenix Contact 1424379 is the identified substitute for the obsolete 1672851 connector hood. Selection is based on:

Product Status Alignment: The 1424379 is in active production status, ensuring availability and ongoing manufacturer support, whereas the 1672851 is obsolete and subject to supply discontinuation.

Compliance Certification: Both components maintain RoHS compliance and identical ECCN/HTSUS classifications, supporting regulatory and procurement requirements.

Functional Equivalence: The 1424379 maintains all critical mechanical and electrical parameters including connector type, size designation, thread configuration, and operating temperature range. The enhanced ingress protection rating (IP66/IP67 versus IP65) provides superior environmental sealing without compromising mechanical fit or electrical performance.

Dimensional Compatibility: Dimensional variations between the two parts (0.5 mm in length and width) fall within standard manufacturing tolerances and do not affect mechanical mounting or interface compatibility.

For applications currently using the 1672851, direct substitution with the 1424379 is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1424379 be used as a direct replacement for the 1672851?

A: Yes. Both components share identical connector type, size, thread configuration, locking mechanism, and operating temperature specifications. The 1424379 is mechanically and functionally compatible with applications designed for the 1672851.

Q: What is the difference in ingress protection between these parts?

A: The 1672851 provides IP65 protection (dust tight, water resistant). The 1424379 provides IP66/IP67 protection (dust tight, water resistant, waterproof). The enhanced rating in the substitute part exceeds the original specification and is suitable for more demanding environmental conditions.

Q: Are there dimensional differences between these connectors?

A: Minor dimensional variations exist: the 1424379 is 0.5 mm longer and 0.5 mm wider than the 1672851. These differences are within standard manufacturing tolerances and do not affect mechanical mounting or interface compatibility.

Q: Why is the 1672851 listed as obsolete?

A: The 1672851 has been discontinued by Phoenix Contact. The 1424379 represents the current production equivalent within the HEAVYCON® D series.

Q: Are both parts RoHS compliant?

A: The 1672851 is explicitly RoHS compliant. The 1424379, as a current Phoenix Contact product in the same series, maintains RoHS compliance standards.

Q: What is the packaging difference between these parts?

A: The 1672851 packaging is not specified in available data. The 1424379 is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Do these connectors have salt water resistance?

A: The 1424379 includes salt water resistant features. The 1672851 does not specify this characteristic. For marine or coastal applications, the 1424379 provides enhanced corrosion protection.
