Phoenix Contact 1771383 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1771383 is a heavy duty connector base designed for box mount, side entry applications with PG16 thread size in the HEAVYCON® B series. This component provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1771383 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B10 size class
• Thread Interface: Must accommodate PG16 thread size
• Lock Mechanism: Must feature Locking Clip (1) on Base Bottom
• Operating Temperature: Must support -40°C to 125°C range
• Material & Construction: Aluminum die cast housing
• Regulatory Compliance: RoHS Compliant status required

The Phoenix Contact 1412842 qualifies as a substitute based on matching all critical mechanical and electrical parameters. While the 1412842 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65), this represents a functional upgrade rather than a limitation, as the connector maintains all core mechanical interfaces and environmental operating specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412842 is the qualified substitute for the obsolete 1771383. Both components maintain identical mechanical interfaces (B10 size, PG16 thread, side entry configuration, locking clip placement) and thermal operating specifications (-40°C to 125°C). The 1412842 is currently in active production status with confirmed inventory availability, addressing the obsolescence constraint of the original part.

The 1412842 provides enhanced ingress protection ratings (IP66/IP67/IP69K) compared to the 1771383 (IP65), along with additional salt water resistance features. These enhancements do not compromise compatibility with existing mechanical or electrical interfaces. Both parts maintain RoHS compliance and identical MSL ratings.

Frequently Asked Questions (FAQ)

Q: Can the 1412842 directly replace the 1771383 in existing installations?

A: Yes. Both components share identical mechanical mounting interfaces (B10 size, PG16 thread, side entry, locking clip configuration) and operate across the same temperature range (-40°C to 125°C). The 1412842 maintains full compatibility with existing connector systems designed for the 1771383.

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

A: The 1771383 provides IP65 protection (dust tight, water resistant). The 1412842 provides IP66/IP67/IP69K protection (dust tight, water resistant, waterproof). The enhanced rating in the 1412842 represents improved environmental sealing and does not affect mechanical or electrical compatibility.

Q: Why is the 1771383 listed as obsolete?

A: The 1771383 is part of the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412842). Phoenix Contact has transitioned production to the newer EVO platform while maintaining mechanical and thermal compatibility.

Q: Are there packaging differences between these parts?

A: The 1771383 was supplied with standard packaging. The 1412842 is available in bulk packaging. Both parts are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What certifications apply to both parts?

A: Both the 1771383 and 1412842 are RoHS compliant and carry ECCN classification EAR99 with HTSUS code 8538.90.8180.
