Phoenix Contact 1604879 Heavy Duty Connector Hood - Equivalent & Substitute Parts
Part Overview
The Phoenix Contact 1604879 is a heavy duty connector hood designed for top entry applications with M40 thread size in the HEAVYCON® B series. 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 currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Engineering Selection Recommendations
The Phoenix Contact 1424855 is the qualified substitute for the obsolete 1604879 connector hood. Both components share identical core specifications across connector type, size designation, thread interface, and operating temperature range. The substitute maintains full mechanical and electrical compatibility while offering enhanced environmental protection through IP66/IP67 rating and salt water resistance features.
The 1424855 is currently in active production status with confirmed inventory availability, whereas the 1604879 is obsolete. For new designs and system replacements, the 1424855 should be specified. Both parts maintain equivalent RoHS compliance status and identical moisture sensitivity levels, ensuring regulatory and reliability parity.
Frequently Asked Questions (FAQ)
Q: Can the 1424855 directly replace the 1604879 in existing installations?
A: Yes. Both components share identical mechanical interfaces (M40 thread, B48 size, top entry configuration) and locking mechanisms. The 1424855 provides enhanced ingress protection (IP66/IP67 versus IP65), making it functionally superior for the same mounting and connection requirements.
Q: What is the difference between IP65 and IP66/IP67 ratings?
A: IP65 provides dust tight and water resistant protection. IP66/IP67 extends this to include waterproof capability under temporary immersion conditions. The 1424855 offers greater environmental sealing for applications exposed to high-pressure water jets or submersion scenarios.
Q: Are there any dimensional differences between these parts?
A: Minor dimensional variations exist. The 1604879 measures 5.177" L × 4.604" W × 3.780" H, while the 1424855 measures 5.197" L × 4.643" W × 4.232" H. These differences are within typical manufacturing tolerances for die cast aluminum housings and do not affect mounting compatibility.
Q: What does "salt water resistant" mean for the 1424855?
A: This feature indicates enhanced corrosion resistance for marine and coastal environments where salt spray exposure occurs. The 1604879 does not specify this capability.
Q: Are both parts RoHS compliant?
A: Yes. The 1604879 is RoHS Compliant, and the 1424855 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.
Q: What is the inventory status for these parts?
A: The 1604879 is obsolete with 706 pieces in stock. The 1424855 is active production with 1026 pieces available in bulk packaging.
