Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1645273 is determined by the following critical parameters:

• Connector Type & Style: Must be Hood connector with Side Entry configuration
• Size & Thread Compatibility: D25 form factor with M25 thread size
• Ingress Protection: IP65 minimum (dust tight, water resistant)
• Operating Temperature Range: -40°C to 125°C
• Housing Material: Aluminum, die cast construction
• Series Compatibility: HEAVYCON® D series

The substitute part 1424377 meets all these criteria while providing enhanced ingress protection (IP66/IP67) and additional salt water resistance features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1424377 is the direct substitute for the obsolete 1645273. Both components share identical mechanical and electrical specifications within the HEAVYCON® D series, including connector type, form factor, thread size, and operating temperature range.

The 1424377 offers functional advantages through enhanced ingress protection (IP66/IP67 versus IP65) and salt water resistance, making it suitable for applications requiring higher environmental protection levels. The part maintains full RoHS compliance (ROHS3) and is currently in active production status, ensuring long-term availability and supply chain continuity.

Dimensional compatibility is confirmed across all critical measurements, with negligible variations (0.02" to 0.02" in length and width) that do not affect mechanical fit or performance in standard mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1424377 directly replace the 1645273 in existing installations?

A: Yes. Both components share identical D25 form factor, M25 thread size, and mechanical mounting specifications. The 1424377 provides equivalent or superior performance with enhanced ingress protection.

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

A: The 1645273 provides IP65 protection (dust tight, water resistant). The 1424377 provides IP66/IP67 protection (dust tight, water resistant, and waterproof). IP66/IP67 offers higher environmental sealing for applications exposed to direct water jets or temporary submersion.

Q: Are there any compliance differences?

A: The 1645273 is RoHS Compliant. The 1424377 is ROHS3 Compliant, representing a more current regulatory standard. Both meet ECCN EAR99 and HTSUS 8538.90.8180 classifications.

Q: Why is the 1645273 listed as obsolete?

A: Obsolescence typically reflects end-of-life status in the manufacturer's product line. The 1424377 represents the current active equivalent within the HEAVYCON® D series.

Q: Are the operating temperature ranges identical?

A: Yes. Both components operate across -40°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: What is the significance of salt water resistance in the 1424377?

A: Salt water resistance indicates enhanced corrosion protection for marine or coastal environments. This feature is not specified for the 1645273 but does not preclude its use in such applications; it simply indicates the 1424377 has been specifically tested and rated for salt water exposure.
