Substitute Part Grouping Explanation

The Phoenix Contact 1604730 can be substituted with part number 1604730 based on the following critical parameters that determine functional equivalence:

Core Compatibility Parameters:

• Connector Type: Base - Box Mount (identical)
• Style: Side Entry (identical)
• Size: B6 (identical)
• Thread Size: M25 (identical)
• Lock Location: Locking Clip (1) on Base Bottom (identical)
• Operating Temperature Range: -40°C to 125°C (identical)
• Housing Material: Aluminum, Die Cast (identical)

Enhanced Specifications in Substitute: The substitute part 1412826 maintains all core mechanical and thermal parameters while providing upgraded ingress protection (IP66/IP67/IP69K versus IP65) and enhanced environmental resistance including salt water resistance. Both parts belong to the Phoenix Contact HEAVYCON® connector family and share identical dimensional footprints for M25 thread mounting.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412826 is the direct substitute for the obsolete 1604730. Both connectors maintain identical mechanical interfaces, thermal operating ranges, and core connector architecture. The 1412826 is currently in active production status with enhanced compliance (ROHS3) and improved ingress protection ratings (IP66/IP67/IP69K), providing superior environmental sealing compared to the original IP65 specification. For applications requiring the original IP65 specification, the 1412826 exceeds these requirements and remains fully compatible. The substitute part is available in higher inventory quantities and represents the current generation equivalent within the Phoenix Contact HEAVYCON® connector portfolio.

Frequently Asked Questions (FAQ)

Q: Can the 1412826 directly replace the 1604730 in existing installations? A: Yes. Both connectors share identical mechanical mounting interfaces (M25 thread, B6 size, side entry configuration) and thermal operating ranges (-40°C to 125°C). The 1412826 provides enhanced ingress protection and is mechanically and electrically compatible.

Q: What is the primary difference between these two connectors? A: The 1412826 provides upgraded ingress protection (IP66/IP67/IP69K) compared to the 1604730 (IP65) and includes salt water resistance. Both maintain identical core specifications for connector type, size, thread configuration, and operating temperature.

Q: Why is the 1604730 listed as obsolete? A: The 1604730 has been superseded by the 1412826 within the Phoenix Contact product line. The newer model offers enhanced environmental protection and compliance certifications while maintaining full mechanical and thermal compatibility.

Q: Are there packaging differences between these parts? A: The 1604730 was supplied with standard packaging, while the 1412826 is available in bulk packaging. Both are identical in form, fit, and function.

Q: Do both connectors meet current compliance standards? A: The 1604730 is RoHS Compliant. The 1412826 meets the more current ROHS3 Compliant standard and is REACH Unaffected, representing current regulatory compliance levels.
