Phoenix Contact 1645176 Heavy Duty Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1645176 is a Heavy Duty Connector hood assembly designed for top entry configuration with M25 thread size and D15 connector size. This component provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -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 1645176 is determined by the following critical parameters:

• Connector Type & Style: Hood configuration with top entry design
• Size Designation: D15 connector size
• Thread Interface: M25 thread size
• Ingress Protection: Minimum IP65 rating (dust tight, water resistant)
• Operating Temperature: -40°C to 125°C capability
• Housing Material: Aluminum die cast construction
• Series Compatibility: HEAVYCON® D series
• Lock Mechanism: Locking clip on base bottom

The substitute part 1424351 maintains all critical mechanical and electrical parameters required for direct functional equivalence within the HEAVYCON® D series platform.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1424351 serves as a direct functional substitute for the obsolete 1645176. Both components share identical mechanical interfaces (D15 size, M25 thread, top entry hood configuration) and thermal operating parameters (-40°C to 125°C). The substitute part 1424351 is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute provides enhanced ingress protection at IP66/IP67 rating compared to the original IP65 specification, representing an improvement in environmental sealing performance. Both parts maintain RoHS compliance and are constructed from aluminum die cast housing. The dimensional variance between parts (1645176: 63.00mm × 29.50mm × 66.00mm versus 1424351: 64.60mm × 30.00mm × 68.00mm) falls within acceptable mechanical tolerance ranges for standard mounting applications.

Frequently Asked Questions (FAQ)

Q: Can part 1424351 directly replace 1645176 in existing installations?

A: Yes. Both parts share identical connector type, size designation (D15), thread interface (M25), locking mechanism, operating temperature range, and housing material. The substitute maintains full mechanical and electrical compatibility.

Q: What is the significance of the IP66/IP67 rating on the substitute part?

A: The substitute part 1424351 provides enhanced ingress protection (IP66/IP67) compared to the original IP65 rating. This represents improved dust and water resistance performance and does not create compatibility issues in applications originally specified for IP65.

Q: Are there packaging differences between these parts?

A: The original part 1645176 packaging information is not specified in available documentation. The substitute part 1424351 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Why is the original part 1645176 listed as obsolete?

A: Product status reflects Phoenix Contact's current manufacturing and support status. The substitute part 1424351 is the active production equivalent within the HEAVYCON® D series.

Q: Are dimensional differences between 1645176 and 1424351 significant?

A: Dimensional variations (approximately 0.5mm in length, 0.5mm in width, and 2mm in height) are within standard mechanical tolerances for die cast aluminum connectors and do not affect functional compatibility or mounting interfaces.

Q: Do both parts maintain the same environmental compliance certifications?

A: Yes. Both the original part 1645176 and substitute part 1424351 are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.
