Phoenix Contact 1673698 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1673698 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG21 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1673698 is based on the following critical parameters that must remain consistent:

• Connector Type & Style: Base - Box Mount, Side Entry configuration
• Size Designation: B16 connector size
• Thread Interface: PG21 thread size for mechanical compatibility
• Operating Temperature Range: -40°C to 125°C minimum requirement
• Housing Material: Aluminum, Die Cast construction
• Lock Mechanism: Locking Clip (1) on Base Bottom
• Manufacturer Ecosystem: Phoenix Contact HEAVYCON® series

The substitute part 1412863 maintains all critical mechanical and electrical parameters while offering enhanced ingress protection (IP66/IP67/IP69K) and improved environmental resistance through the HEAVYCON® EVO series evolution. Both parts share identical connector size, thread interface, operating temperature range, and housing material specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412863 serves as the direct substitute for the obsolete 1673698. Both connectors maintain identical mechanical interfaces (B16 size, PG21 thread, side entry configuration) and thermal operating specifications (-40°C to 125°C). The 1412863 is classified as an active product with current manufacturing support, ensuring long-term availability and supply chain continuity.

The substitute part offers enhanced ingress protection (IP66/IP67/IP69K versus IP65) and includes salt water resistance features through the HEAVYCON® EVO series platform. Both parts maintain RoHS compliance and unlimited moisture sensitivity rating (MSL 1), supporting deployment in industrial control and harsh environment applications.

Dimensional variations between the parts are minimal (height difference of 1.00mm), and both employ identical locking mechanisms and housing materials. Selection of the 1412863 is supported by its active product status and improved environmental protection specifications while maintaining full mechanical and electrical compatibility with existing B16 connector ecosystems.

Frequently Asked Questions (FAQ)

Q: Can the 1412863 directly replace the 1673698 in existing installations?

A: Yes. Both connectors share identical connector size (B16), thread interface (PG21), operating temperature range (-40°C to 125°C), housing material (aluminum die cast), and locking mechanism (clip on base bottom). Mechanical and electrical compatibility is maintained.

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

A: The 1412863 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the 1673698 (IP65) and includes salt water resistance. The 1412863 represents the current generation HEAVYCON® EVO series, while the 1673698 is from the legacy HEAVYCON® B series.

Q: Why is the 1673698 listed as obsolete?

A: The 1673698 has been superseded by the 1412863 in Phoenix Contact's product portfolio. The newer part offers improved environmental protection and is the recommended solution for new designs and replacement applications.

Q: Are there packaging differences between these parts?

A: The 1673698 is supplied in standard packaging, while the 1412863 is supplied in bulk packaging. This does not affect connector functionality or compatibility.

Q: Do both connectors meet RoHS compliance requirements?

A: Yes. The 1673698 is ROHS3 compliant, and the 1412863 is RoHS compliant. Both parts meet current environmental and regulatory standards.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 1673698 and 1412863 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.
