Phoenix Contact 1673449 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1673449 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG16 thread size in the HEAVYCON® B series. This connector 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 system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1673449 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector Type: Base - Box Mount (mechanical mounting interface)
• Style: Side Entry (cable entry orientation)
• Size: B10 (contact arrangement and housing envelope)
• Thread Size: PG16 (cable gland interface)
• Operating Temperature Range: -40°C to 125°C (thermal compatibility)
• Housing Material: Aluminum, Die Cast (material specification)

Functional Enhancement Parameters:

• Ingress Protection: Equal or superior rating (IP65 minimum)
• RoHS Compliance: ROHS3 or equivalent regulatory status

The substitute part 1412842 maintains all core compatibility parameters while providing enhanced ingress protection (IP66/IP67/IP69K) and additional features (salt water resistance, feed through capability). The dimensional variance (height: 2.047" vs. 2.150") remains within acceptable mechanical tolerance for box mount applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412842 serves as a direct functional substitute for the obsolete 1673449 based on the following engineering criteria:

Mechanical Compatibility: Both connectors maintain identical B10 size, PG16 thread interface, and side entry configuration. The dimensional variance of 0.103" (2.6mm) in height is within standard mechanical tolerance for box mount applications and does not compromise installation compatibility.

Electrical and Environmental Performance: The 1412842 provides equivalent operating temperature range (-40°C to 125°C) and exceeds the ingress protection requirement with IP66/IP67/IP69K rating versus the original IP65 specification. This enhancement provides superior environmental sealing without functional degradation.

Regulatory Compliance: Both parts maintain RoHS compliance status (ROHS3 and RoHS Compliant respectively), ensuring regulatory alignment for industrial applications. ECCN and HTSUS classifications remain consistent.

Product Lifecycle: The 1412842 is active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 1673449.

Frequently Asked Questions (FAQ)

Q: Can the 1412842 directly replace the 1673449 in existing installations?

A: Yes. Both connectors share identical connector type (base - box mount), style (side entry), size (B10), and thread size (PG16). The mechanical mounting interface and cable gland connection are fully compatible. The dimensional height difference of 0.103" does not affect box mount installation.

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

A: The 1673449 provides IP65 protection (dust tight, water resistant). The 1412842 provides IP66/IP67/IP69K protection (dust tight, water resistant, waterproof). The 1412842 offers enhanced environmental sealing suitable for more demanding applications including salt water environments.

Q: Are there any temperature operating differences?

A: No. Both connectors operate across the identical temperature range of -40°C to 125°C.

Q: What is the significance of the series change from HEAVYCON® B to HEAVYCON® EVO?

A: The series designation reflects product line evolution. The HEAVYCON® EVO represents the current generation with enhanced features (feed through capability, salt water resistance) while maintaining backward compatibility with the B series mechanical interface.

Q: Does the 1412842 require different packaging or handling?

A: The 1412842 is supplied in bulk packaging. Both parts maintain MSL 1 (Unlimited) moisture sensitivity level, requiring identical storage and handling protocols.

Q: Are RoHS compliance statuses equivalent?

A: Both parts maintain RoHS compliance. The 1673449 is ROHS3 Compliant, and the 1412842 is RoHS Compliant. Both meet current regulatory requirements for industrial applications.
