Phoenix Contact 1604749 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604749 is a Heavy Duty Connector base unit designed for box mount, side entry applications with M25 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 product is classified as obsolete, making identification of functionally equivalent substitute parts essential 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 1604749 is determined by the following critical parameters that must remain constant or be enhanced:

• Connector Type & Style: Must be Base - Box Mount, Side Entry configuration
• Size Designation: B10 size class
• Thread Size: M25 thread specification
• Ingress Protection: Must meet or exceed IP65 rating
• Operating Temperature Range: Must support -40°C to 125°C
• Housing Material: Aluminum die cast construction
• Regulatory Compliance: RoHS compliance required

The substitute part Phoenix Contact 1412840 maintains all critical mechanical and electrical parameters while providing enhanced ingress protection (IP66/IP67/IP69K) and improved environmental resistance characteristics. Both parts share identical connector type, size, thread specification, and temperature operating range, with the substitute offering superior dust and water ingress protection suitable for more demanding environmental conditions.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412840 serves as the direct substitute for the obsolete 1604749 model. Both connectors maintain identical mechanical interface specifications (B10 size, M25 thread, side entry configuration) and thermal operating range (-40°C to 125°C), ensuring drop-in compatibility in existing mounting applications.

The 1412840 is classified as an active product with current manufacturing support, whereas the 1604749 is obsolete. The substitute provides enhanced ingress protection (IP66/IP67/IP69K versus IP65), offering superior performance in dust and water exposure scenarios. Both parts maintain aluminum die cast housing construction and comply with RoHS directives (the substitute meets ROHS3 specification). Dimensional variations are minimal (height difference of 2.60mm), with no impact on standard M25 mounting interfaces.

Selection of the 1412840 is appropriate for new designs, system upgrades, and replacement applications where the original 1604749 is no longer available through standard procurement channels.

Frequently Asked Questions (FAQ)

Q: Can the 1412840 directly replace the 1604749 in existing installations?

A: Yes. Both connectors share identical connector type (Base - Box Mount), style (Side Entry), size (B10), thread specification (M25), and operating temperature range (-40°C to 125°C). The mechanical interface is compatible with existing M25 mounting provisions.

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

A: The 1412840 provides enhanced ingress protection (IP66/IP67/IP69K) compared to the 1604749 (IP65). The substitute also represents the current active product line (HEAVYCON® EVO series) versus the obsolete HEAVYCON® B series.

Q: Are there dimensional compatibility concerns?

A: Dimensional differences are minimal. The 1412840 is 2.60mm taller (54.60mm versus 52.00mm height) and 1.00mm shorter in length (92.00mm versus 93.00mm). These variations do not affect M25 thread mounting or standard enclosure integration.

Q: Do both connectors meet current regulatory requirements?

A: The 1604749 is RoHS Compliant. The 1412840 meets ROHS3 Compliant specification, representing current regulatory standards. Both are classified under ECCN EAR99 and HTSUS 8538.90.8180.

Q: What packaging options are available?

A: The 1604749 is available in standard packaging. The 1412840 is supplied in bulk packaging format.

Q: Is the 1412840 suitable for high-moisture or saltwater environments?

A: Yes. The 1412840 includes salt water resistant features and achieves IP69K rating, making it suitable for harsh environmental conditions including high-pressure water exposure and corrosive atmospheres.
