Phoenix Contact 1646492 Heavy Duty Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1646492 is a base-mount, side-entry heavy duty connector from the HEAVYCON® B series, designed for M20 thread applications with B10 size configuration. 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 compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1646492 is determined by the following critical parameters:

• Connector Type & Style: Must be base-mount, side-entry configuration
• Size Designation: B10 size class
• Thread Interface: M20 thread size
• Ingress Protection: IP65 minimum (equal or higher rating acceptable)
• Operating Temperature: -40°C to 125°C range
• Housing Material: Aluminum die-cast construction
• RoHS Compliance: Required for regulatory alignment
• Mechanical Compatibility: Locking clip configuration on hood

The substitute part 1412830 meets all critical substitution criteria while offering enhanced environmental protection and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412830 is the qualified substitute for the obsolete 1646492. Both connectors maintain identical mechanical interfaces (M20 thread, B10 size, side-entry configuration) and thermal operating range (-40°C to 125°C). The substitute provides superior ingress protection (IP66/IP67/IP69K versus IP65) and includes salt water resistance, making it suitable for equivalent or more demanding environmental conditions.

The 1412830 carries active product status with RoHS compliance, ensuring long-term availability and regulatory alignment. The dimensional increase (54.00mm height versus 52.00mm) is negligible for most mounting applications and does not affect the core mechanical interface.

Frequently Asked Questions (FAQ)

Q: Can the 1412830 directly replace the 1646492 in existing installations?

A: Yes. Both connectors share identical connector type, style, size designation (B10), thread size (M20), locking mechanism, and operating temperature range. The mechanical interface is fully compatible.

Q: What is the significance of the higher IP rating on the substitute?

A: The 1412830 provides IP66/IP67/IP69K protection compared to the 1646492's IP65. This represents enhanced dust and water ingress protection. IP66/IP67/IP69K ratings are backward-compatible with IP65 applications, meaning the substitute can be used in any environment where the original was specified.

Q: Are there dimensional differences that affect mounting?

A: The 1412830 is 2.00mm taller (54.00mm versus 52.00mm height). All other dimensions remain identical. Verify available mounting space before installation, though this minor difference rarely impacts standard enclosure applications.

Q: Why is the original part obsolete?

A: The 1646492 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412830). Phoenix Contact has transitioned product lines to the newer EVO platform, which offers improved environmental protection and salt water resistance.

Q: Is the substitute available in the same packaging as the original?

A: The 1412830 is supplied in bulk packaging, whereas the original 1646492 packaging specification was not provided. Confirm packaging requirements with your procurement process.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1646492 and 1412830 are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.
