Phoenix Contact 1771590 HEAVYCON® B Base Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1771590 is a heavy-duty panel mount base connector for bottom entry applications in the HEAVYCON® B series. This component functions as the base unit for B16-sized connector assemblies, featuring a die-cast aluminum housing with powder coating and operating across -40°C to 125°C. The part is classified as obsolete, making identification of active equivalent models essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1771590 has one direct substitute: 1411324. This substitution is valid based on the following alignment of critical parameters:

• Connector Type & Function: Both are base panel mount connectors for bottom entry applications
• Size Designation: Both are B16-sized connectors, ensuring mechanical compatibility with existing B16 contact sets and mating interfaces
• Series Compatibility: The 1411324 belongs to the HEAVYCON® EVO series, which is the active evolution of the HEAVYCON® B series
• Operating Temperature: Identical range of -40°C to 125°C
• Housing Material: Both use die-cast aluminum construction
• Lock Mechanism: Both feature a single locking clip on the base bottom
• Regulatory Compliance: Both are RoHS compliant (1771590: RoHS, 1411324: ROHS3)
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The 1411324 represents an enhanced version with improved ingress protection (IP66/IP67) and salt water resistance, making it suitable for applications requiring higher environmental protection while maintaining backward compatibility with B16 contact systems.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The 1411324 is the direct active substitute for the obsolete 1771590. Both parts maintain identical B16 sizing and bottom entry configuration, ensuring compatibility with existing contact sets and mating connectors within the HEAVYCON® ecosystem.

Compliance Consideration: The 1411324 meets ROHS3 compliance, representing current regulatory standards, while the 1771590 meets RoHS compliance. For new designs or systems requiring current compliance documentation, the 1411324 is the appropriate selection.

Environmental Protection: The 1411324 provides IP66/IP67 ingress protection with salt water resistance. In applications where the original 1771590 operated without specified ingress protection, the 1411324 offers enhanced environmental sealing without compromising the core connector function.

Physical Dimensions: The 1411324 has slightly larger width (53mm vs 43mm) and height (30.50mm vs 27mm) dimensions while maintaining the same length. Panel cutout and mounting space must be verified for retrofit applications.

Frequently Asked Questions (FAQ)

Q: Can the 1411324 directly replace the 1771590 in existing assemblies? A: Yes. Both connectors are B16-sized base panel mount units with identical bottom entry configuration and locking mechanisms. Contact sets and mating connectors designed for the 1771590 are compatible with the 1411324.

Q: What is the primary difference between these two parts? A: The 1411324 is the active HEAVYCON® EVO series equivalent of the obsolete HEAVYCON® B 1771590. The 1411324 adds IP66/IP67 ingress protection and salt water resistance while maintaining the same core connector size and function.

Q: Are there dimensional compatibility concerns? A: The 1411324 is slightly larger in width and height (53mm x 30.50mm vs 43mm x 27mm). Panel mounting cutouts and surrounding component placement must be verified before substitution in space-constrained applications.

Q: Do both parts support the same operating temperature range? A: Yes. Both the 1771590 and 1411324 operate across -40°C to 125°C.

Q: Which part should be specified for new designs? A: The 1411324 should be specified for new designs. It is an active product with current compliance certifications (ROHS3) and enhanced environmental protection suitable for modern industrial applications.

Q: Is the 1411324 available in the same packaging as the 1771590? A: The 1771590 packaging is not specified in the original documentation. The 1411324 is available in bulk packaging.
