Engineering Selection Recommendations
The Phoenix Contact 1424874 serves as a direct functional substitute for the obsolete 1604878. Both components maintain identical mechanical interfaces (M40 thread, B48 size, side entry configuration) and thermal operating ranges. The 1424874 is currently in active production status with 750 units available in inventory, compared to the 1604878 which is obsolete with limited remaining stock.
The primary technical distinction is the enhanced ingress protection rating: the 1424874 provides IP66/IP67 protection versus the IP65 rating of the original part. This represents an improvement in environmental sealing capability, with the substitute offering waterproof performance in addition to dust and water resistance. Both components maintain RoHS compliance and identical housing material specifications.
For applications requiring the original IP65 specification, the 1424874 remains compatible as IP66/IP67 protection exceeds the original requirement. The substitute's active product status ensures long-term availability and supply chain continuity.
Frequently Asked Questions (FAQ)
Q: Can the 1424874 directly replace the 1604878 in existing installations?
A: Yes. Both components share identical mechanical interfaces (M40 thread, B48 size), connector type (Base - Box Mount), style (Side Entry), and operating temperature range (-40°C to 125°C). The mounting footprint and locking mechanism are identical.
Q: What is the difference in ingress protection between these parts?
A: The 1604878 provides IP65 protection (dust tight, water resistant). The 1424874 provides IP66/IP67 protection (dust tight, water resistant, and waterproof). The substitute offers enhanced environmental sealing without compromising compatibility.
Q: Are both parts RoHS compliant?
A: Yes. Both the 1604878 and 1424874 are RoHS Compliant, meeting regulatory requirements for hazardous substance restrictions.
Q: Why is the 1604878 listed as obsolete?
A: The 1604878 has been discontinued by Phoenix Contact. The 1424874 represents the current active production equivalent within the HEAVYCON® B series.
Q: What are the dimensional differences between these connectors?
A: The 1604878 measures 5.709" L × 4.724" W × 3.937" H (145.00mm × 120.00mm × 100.00mm). The 1424874 measures 5.197" L × 4.724" W × 3.898" H (132.00mm × 120.00mm × 99.00mm). Width dimensions are identical; length and height show minor variations within the B48 form factor.
Q: Is the 1424874 available in the same packaging as the 1604878?
A: The 1604878 was supplied in standard packaging. The 1424874 is available in Bulk packaging with 750 units currently in stock.
