Phoenix Contact 1604721 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1604721 is a Heavy Duty Connector base unit designed for box mount, side entry applications with M20 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a wide temperature range of -40°C to 125°C. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation

The Phoenix Contact 1412821 qualifies as a direct substitute for the 1604721 based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Connector Type: Base - Box Mount (identical)
• Style: Side Entry (identical)
• Size: B6 (identical)
• Thread Size: M20 (identical)
• Lock Location: Locking Clip (1) on Base Bottom (identical)
• Operating Temperature Range: -40°C to 125°C (identical)
• Housing Material: Aluminum, Die Cast (identical)
• Manufacturer: Phoenix Contact (same manufacturer ecosystem)

Enhanced Specifications in Substitute: The 1412821 represents an evolution within the Phoenix Contact product line, offering improved ingress protection (IP66/IP67/IP69K versus IP65) and additional features including salt water resistance and feed-through capability. These enhancements maintain backward compatibility while providing superior environmental protection for demanding applications.

Parameter Comparison

Engineering Selection Recommendations

The 1412821 is the appropriate substitute for the obsolete 1604721 based on the following engineering criteria:

Product Status Alignment: The 1604721 is classified as obsolete, while the 1412821 maintains active product status with current manufacturing support and availability. This transition ensures long-term supply chain continuity and access to technical support.

Compliance and Certification: Both parts maintain RoHS compliance. The 1412821 carries ROHS3 certification, representing current regulatory alignment. The 1412821 additionally holds REACH Unaffected status, providing enhanced environmental documentation for regulated markets.

Functional Compatibility: Core mechanical and electrical parameters remain identical across both parts, including connector type, size designation, thread specification, and operating temperature range. This ensures direct mechanical and electrical interchangeability in existing installations.

Enhanced Environmental Protection: The 1412821 provides superior ingress protection (IP66/IP67/IP69K) compared to the IP65 rating of the 1604721. This enhancement does not compromise compatibility but extends application capability to more demanding environmental conditions, including high-pressure wash environments (IP69K).

Frequently Asked Questions (FAQ)

Q: Can the 1412821 directly replace the 1604721 in existing installations?

A: Yes. Both parts share identical connector type, size (B6), thread size (M20), style (side entry), and operating temperature range (-40°C to 125°C). The mechanical mounting interface and electrical specifications are compatible, enabling direct substitution without system redesign.

Q: What is the significance of the higher IP rating on the 1412821?

A: The 1412821 provides IP66/IP67/IP69K protection versus the IP65 rating of the 1604721. This means the substitute offers enhanced dust and water resistance, including protection against high-pressure water jets (IP69K). This represents an improvement in environmental sealing without affecting core connector functionality.

Q: Are there dimensional differences between these parts?

A: The height dimension differs slightly: the 1604721 measures 2.047" (52.00mm), while the 1412821 measures 2.150" (54.60mm). The length (3.307" / 84.00mm) and width (2.047" / 52.00mm) remain identical. Verify mounting clearance in space-constrained applications.

Q: What is the packaging difference between these parts?

A: The 1604721 is supplied with standard packaging, while the 1412821 is supplied in bulk packaging. Confirm packaging requirements for your procurement and inventory management processes.

Q: Why is the 1604721 classified as obsolete?

A: The 1604721 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by the 1412821). Phoenix Contact has transitioned product lines to the newer EVO generation, which incorporates enhanced environmental protection and current compliance certifications.

Q: Are both parts RoHS compliant?

A: Yes. The 1604721 is RoHS Compliant, and the 1412821 is ROHS3 Compliant. Both meet RoHS requirements; the 1412821 carries the current ROHS3 certification standard.
