Phoenix Contact 1646340 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1646340 is a base-mount side entry heavy duty connector from the HEAVYCON® B series, designed for M25 thread applications with B24 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 suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1646340 can be substituted with part number 1412877 based on the following alignment of critical parameters:

Matching Parameters:

• Connector Type: Base - Box Mount (identical)
• Style: Side Entry (identical)
• Size: B24 (identical)
• Thread Size: M25 (identical)
• Lock Location: Locking Clip (1) on Base Bottom (identical)
• Operating Temperature Range: -40°C ~ 125°C (identical)
• Housing Material: Aluminum, Die Cast (identical)
• RoHS Compliance: RoHS Compliant (identical)

Enhanced Specification: The substitute part 1412877 belongs to the HEAVYCON® EVO series and provides upgraded ingress protection (IP66/IP67/IP69K) compared to the original IP65 rating, with additional salt water resistance features. This represents a direct functional upgrade while maintaining mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412877 is the direct substitute for the obsolete 1646340. Both components maintain identical mechanical interfaces (M25 thread, B24 size, side entry configuration) and thermal operating ranges. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The 1412877 provides enhanced environmental protection through upgraded IP66/IP67/IP69K ratings and salt water resistance features, making it suitable for applications requiring higher ingress protection levels than the original IP65 specification. Both parts maintain RoHS compliance and identical moisture sensitivity classifications.

Frequently Asked Questions (FAQ)

Q: Can the 1412877 directly replace the 1646340 in existing installations?

A: Yes. The 1412877 maintains identical mechanical mounting interfaces (M25 thread, B24 size, side entry style) and locking mechanisms. The base-mount configuration and thermal operating range (-40°C ~ 125°C) are unchanged, ensuring direct compatibility in existing connector assemblies.

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

A: The 1412877 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65) and includes salt water resistance features. Both parts use identical aluminum die-cast housing and maintain the same operating temperature range and RoHS compliance status.

Q: Why is the 1646340 listed as obsolete?

A: The 1646340 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412877). Phoenix Contact has transitioned production to the newer EVO platform while maintaining mechanical and thermal compatibility.

Q: Are there any dimensional differences between these parts?

A: The height dimension differs slightly: 1646340 measures 2.638" H (67.00mm), while 1412877 measures 2.677" H (68.00mm). Length and width dimensions remain identical at 5.669" L x 2.244" W (144.00mm x 57.00mm).

Q: What packaging options are available?

A: The 1646340 original specification does not specify packaging details. The 1412877 substitute is available in bulk packaging configuration.
