Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1424404 is a direct functional substitute for the obsolete 1645286. Both connectors share identical mechanical interfaces (D50 size, M32 thread, side entry configuration) and thermal operating range. The 1424404 provides enhanced environmental protection with IP66/IP67 rating versus the IP65 of the original part, along with salt water resistance. The 1424404 maintains active product status with current ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and system replacements.

Frequently Asked Questions (FAQ)

Q: Can the 1424404 directly replace the 1645286 in existing installations?

A: Yes. Both connectors share identical mechanical mounting (M32 thread, D50 size, side entry style) and electrical operating parameters (-40°C to 125°C). The 1424404 provides equivalent or superior performance with higher ingress protection.

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

A: The 1645286 provides IP65 protection (dust tight, water resistant). The 1424404 provides IP66/IP67 protection (dust tight, water resistant, waterproof). IP66/IP67 offers enhanced protection in high-moisture or submersion environments.

Q: Are there compatibility concerns with existing mating connectors?

A: No. Both parts use identical D50 connector sizing and M32 threading, ensuring mechanical and electrical compatibility with existing mating components.

Q: Why is the 1645286 listed as obsolete?

A: The 1645286 has been discontinued by Phoenix Contact. The 1424404 represents the current active product line for this connector category and should be specified for new designs.

Q: What is the packaging difference?

A: The 1645286 was supplied with standard packaging. The 1424404 is supplied in bulk packaging, which may affect procurement and inventory management.
