Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1645477 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Panel Mount with Bottom Entry configuration
• Size Class: Must be B10 to ensure mechanical and electrical compatibility with existing mating connectors
• Lock Mechanism: Must feature Locking Clip (1) on Base Bottom for consistent installation and retention
• Housing Material & Construction: Aluminum die-cast construction maintains structural integrity and thermal characteristics
• Operating Temperature: Must support -40°C to 125°C range for equivalent environmental performance
• Regulatory Compliance: RoHS compliance required for modern supply chain acceptance

The substitute part 1411321 meets all mandatory substitution criteria while providing enhanced environmental protection through IP66 ingress rating and salt water resistance features. Both parts maintain identical size class (B10), connector type (Base - Panel Mount), entry style (Bottom Entry), and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The 1411321 serves as the direct active equivalent for the obsolete 1645477. Selection should be based on the following engineering factors:

Product Status: The 1645477 is obsolete, creating supply chain risk for future procurement. The 1411321 is active and maintains full manufacturer support.

Regulatory Compliance: Both parts meet RoHS requirements. The 1411321 achieves ROHS3 compliance, representing current regulatory standards. The 1411321 also carries REACH Unaffected status, providing additional compliance documentation.

Environmental Performance: The 1411321 provides IP66 ingress protection and salt water resistance, offering enhanced durability in harsh environments compared to the unspecified ingress rating of the 1645477. This upgrade does not compromise compatibility with existing B10 mating connectors.

Mechanical Compatibility: Both parts maintain identical B10 size class, bottom entry configuration, and locking clip retention, ensuring direct mechanical substitution in panel mount applications.

For new designs or system upgrades, the 1411321 is the appropriate selection. For legacy system maintenance requiring exact form-factor matching, the 1645477 remains available in current inventory (1029 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 1411321 directly replace the 1645477 in existing installations?

A: Yes. Both connectors share identical B10 size class, bottom entry style, and locking clip mechanism. The 1411321 is mechanically and electrically compatible with all existing B10 mating connectors designed for the 1645477.

Q: What is the primary difference between these two parts?

A: The 1411321 belongs to the HEAVYCON® EVO series and includes IP66 ingress protection with salt water resistance features. The 1645477 is from the earlier HEAVYCON® B series without specified ingress protection. Both maintain identical operating temperature range (-40°C to 125°C) and core mechanical specifications.

Q: Why is the 1645477 listed as obsolete?

A: The 1645477 has been superseded by the 1411321 in the Phoenix Contact product line. The newer EVO series provides enhanced environmental protection while maintaining backward compatibility with existing B10 connector systems.

Q: Are there dimensional differences between these parts?

A: Yes. The 1411321 measures 94.60mm L x 53.00mm W x 30.50mm H, compared to the 1645477 at 93.00mm L x 43.00mm W x 27.00mm H. These dimensional changes accommodate the integrated cover and enhanced ingress protection features. Panel cutout dimensions should be verified for retrofit applications.

Q: What certifications apply to the 1411321?

A: The 1411321 is ROHS3 compliant, REACH Unaffected, and carries EAR99 export classification. It meets IP66 environmental sealing standards for dust and water resistance.

Q: Can I use the 1645477 for new designs?

A: No. As an obsolete part, the 1645477 is not recommended for new designs. The 1411321 should be specified for all new applications to ensure long-term supply chain availability and access to manufacturer technical support.
