Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1604969 is determined by strict alignment of the following critical parameters:

• Connector Type & Style: Must be Hood connector with Side Entry configuration
• Size Designation: D25 form factor required for mechanical compatibility
• Thread Size: M25 threading for mounting interface compatibility
• Series Compatibility: HEAVYCON® D series maintains design consistency
• Operating Temperature: -40°C to 125°C range must be maintained or exceeded
• Housing Material: Aluminum die cast construction for thermal and mechanical properties
• Lock Mechanism: Locking Clip (1) on Base Bottom configuration

The substitute part 1604969 → 1424377 maintains all critical mechanical and electrical parameters while providing enhanced ingress protection (IP66/IP67 versus IP65) and improved environmental resistance through salt water resistant features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1424377 is the direct substitute for the obsolete 1604969. Selection is based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical D25 form factor, M25 thread size, and HEAVYCON® D series designation, ensuring direct mechanical interchangeability in existing mounting interfaces.

Environmental Performance: The 1424377 provides enhanced ingress protection (IP66/IP67 versus IP65) and includes salt water resistant features, offering superior environmental durability without compromising the original operating temperature range (-40°C to 125°C).

Regulatory Compliance: The 1424377 carries ROHS3 Compliant status and REACH Unaffected designation, meeting current regulatory requirements. The original 1604969 is RoHS Compliant but obsolete.

Product Availability: The 1424377 maintains Active product status with 968 units in stock, ensuring supply chain continuity for both replacement and new design applications.

Frequently Asked Questions (FAQ)

Q: Can the 1424377 directly replace the 1604969 in existing installations?

A: Yes. Both connectors share identical mechanical interfaces (D25 size, M25 thread, Side Entry style, HEAVYCON® D series) and identical operating temperature ranges (-40°C to 125°C). The 1424377 is mechanically and functionally interchangeable.

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

A: The 1604969 provides IP65 protection (dust tight, water resistant). The 1424377 provides IP66/IP67 protection (dust tight, water resistant, and waterproof). The enhanced rating in the substitute part represents an improvement in environmental sealing performance.

Q: Are there any compliance differences between the two parts?

A: The 1604969 is RoHS Compliant. The 1424377 is ROHS3 Compliant, representing a more current regulatory standard. The 1424377 also carries REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: What does the salt water resistant feature on the 1424377 provide?

A: Salt water resistance indicates enhanced corrosion protection for applications in marine or coastal environments with high salt exposure. This feature is not specified for the 1604969.

Q: Are the physical dimensions identical?

A: Dimensions are nearly identical with minimal variation: 1604969 measures 3.130" L × 1.161" W × 2.835" H (79.50mm × 29.50mm × 72.00mm); 1424377 measures 3.150" L × 1.181" W × 2.835" H (80.00mm × 30.00mm × 72.00mm). These differences are within normal manufacturing tolerances and do not affect mechanical compatibility.

Q: Why is the 1604969 classified as obsolete?

A: Obsolescence typically results from manufacturer discontinuation due to product line consolidation, improved successor designs, or market demand shifts. The 1424377 represents the current active equivalent in the HEAVYCON® D product line.
