Phoenix Contact 1645202 Heavy Duty Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1645202 is a Heavy Duty Connector hood assembly designed for top entry configuration with M25 thread size and D50 connector size. This component provides IP65 ingress protection (dust tight, water resistant) and operates across a wide temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The HEAVYCON® D series construction utilizes die-cast aluminum with powder coating for durability in industrial environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1645202 is determined by the following critical parameters:

Core Compatibility Parameters:

• Manufacturer Series: HEAVYCON® D (ensures mechanical and electrical compatibility within the product family)
• Connector Size: D50 (maintains interface compatibility with mating components)
• Thread Size: M25 (ensures proper mechanical mounting and sealing)
• Housing Material: Aluminum, Die Cast (provides equivalent structural and thermal properties)
• Operating Temperature Range: -40°C to 125°C (maintains functional performance envelope)
• RoHS Compliance: Required for regulatory alignment

Acceptable Variation Parameters:

• Entry Style: Top Entry or Side Entry (both configurations support the same electrical and mechanical interface within the D50/M25 specification)
• Ingress Protection: IP65 or higher (IP66/IP67 provides equal or superior environmental sealing)
• Housing Finish: Powder Coated or equivalent protective coating

The substitute part 1424403 meets all core compatibility parameters while offering enhanced ingress protection (IP66/IP67) and salt water resistance, making it suitable for equivalent or more demanding applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1424403 is a direct functional equivalent for the obsolete 1645202 within the HEAVYCON® D series. Both components share identical core specifications: D50 connector size, M25 thread interface, aluminum die-cast construction, and -40°C to 125°C operating range. Both maintain RoHS compliance for regulatory requirements.

The 1424403 offers two technical advantages: enhanced ingress protection (IP66/IP67 versus IP65) and documented salt water resistance. The side entry configuration, while differing from the top entry design of the 1645202, maintains full mechanical and electrical compatibility within the D50/M25 interface specification. The 4mm height difference (80mm versus 76mm) reflects the side entry geometry and does not affect connector interface compatibility.

The 1424403 is currently in active production status, ensuring supply chain availability and long-term support compared to the obsolete 1645202.

Frequently Asked Questions (FAQ)

Q: Can the 1424403 directly replace the 1645202 in existing installations?

A: Yes. Both components share the same D50 connector size, M25 thread specification, and HEAVYCON® D series architecture. The mechanical mounting interface and electrical performance envelope are equivalent. The side entry configuration of the 1424403 requires verification of cable routing geometry in the specific installation, but does not affect connector compatibility.

Q: What is the significance of the IP66/IP67 rating on the 1424403 compared to the IP65 rating on the 1645202?

A: IP66/IP67 provides enhanced environmental sealing. IP65 specifies dust tight and water resistant performance. IP66 adds protection against high-pressure water jets, and IP67 adds temporary immersion capability. The 1424403 is suitable for applications requiring equal or greater environmental protection than the original 1645202.

Q: Are there any compliance or certification differences between these parts?

A: Both components are RoHS compliant and share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. No compliance barriers exist for substitution.

Q: Why is the 1645202 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The 1424403 represents the current production equivalent within the HEAVYCON® D series, ensuring access to supported inventory and ongoing technical support.

Q: Does the height difference (76mm versus 80mm) affect installation?

A: The 4mm height difference results from the side entry design geometry of the 1424403. Verify that the installation envelope accommodates this dimension. The connector interface and mounting footprint remain compatible with the D50/M25 specification.
