Phoenix Contact 1604751 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604751 is a heavy duty connector base designed for box mount, side entry applications with M25 thread size in the HEAVYCON® B series. This component 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

Substitution eligibility for the Phoenix Contact 1604751 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount, Side Entry configuration
• Size Designation: Must be B10 size class
• Thread Size: Must be M25 thread specification
• Ingress Protection: Must meet or exceed IP65 rating
• Operating Temperature: Must support -40°C to 125°C range
• Housing Material: Must be Aluminum, Die Cast
• RoHS Compliance: Must maintain RoHS Compliant status

The substitute part 1412845 satisfies all substitution criteria. It maintains identical connector type, style, size, and thread specifications while providing enhanced ingress protection (IP66/IP67) and additional salt water resistance features. Both parts operate within the same temperature range and maintain RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412845 is the direct substitute for the obsolete 1604751. Both components share identical mechanical and electrical specifications for connector type, size, thread configuration, and operating temperature range. The 1412845 provides enhanced ingress protection at IP66/IP67 versus the original IP65 rating, with additional salt water resistance features. As an active product in the HEAVYCON® EVO series, the 1412845 maintains full RoHS compliance and ensures continued availability for system maintenance and new installations.

Frequently Asked Questions (FAQ)

Q: Can the 1412845 directly replace the 1604751 in existing installations?

A: Yes. Both components share identical connector type (Base - Box Mount), style (Side Entry), size (B10), thread size (M25), and operating temperature range (-40°C to 125°C). The 1412845 provides equal or superior performance with enhanced IP66/IP67 ingress protection.

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

A: The 1412845 belongs to the HEAVYCON® EVO series and provides IP66/IP67 ingress protection with salt water resistance, compared to the 1604751's IP65 rating. The 1604751 is obsolete; the 1412845 is an active product.

Q: Are there dimensional differences between the two parts?

A: Minor dimensional variations exist. The 1604751 measures 3.661" L x 2.047" W x 2.047" H (93.00mm x 52.00mm x 52.00mm), while the 1412845 measures 3.622" L x 2.047" W x 2.150" H (92.00mm x 52.00mm x 54.60mm). These differences do not affect mechanical compatibility for standard box mount applications.

Q: Do both parts maintain RoHS compliance?

A: Yes. Both the 1604751 and 1412845 are RoHS Compliant and operate within the same -40°C to 125°C temperature range.

Q: What packaging options are available?

A: The 1604751 is available in standard packaging, while the 1412845 is supplied in bulk packaging.
