Phoenix Contact 1673740 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1673740 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG21 thread size and B16 connector size. This component provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1673740 is determined by strict alignment with the following core parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: B16 connector size is mandatory for mechanical and electrical compatibility
• Thread Size: PG21 thread specification ensures proper mounting interface
• Lock Mechanism: Locking Clip (2) on Base Bottom maintains installation consistency
• Operating Temperature: Minimum -40°C to 125°C range required
• Housing Material: Aluminum, Die Cast construction for structural equivalence

The substitute part Phoenix Contact 1412857 meets all mandatory parameters while providing enhanced ingress protection (IP66/IP67/IP69K) and additional features including salt water resistance and feed-through capability. Both parts maintain identical connector type, size, thread specification, and locking configuration, with dimensional variations within acceptable tolerance ranges for the B16 PG21 form factor.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412857 serves as a direct substitute for the obsolete 1673740 based on maintained mechanical and electrical compatibility across all critical parameters. The substitute part is classified as Active product status, ensuring continued availability and supply chain reliability.

The 1412857 provides enhanced environmental protection through IP66/IP67/IP69K ingress rating compared to the IP65 specification of the original part. This represents an improvement in dust and water resistance capability without compromising any existing functional requirements. Both parts maintain identical operating temperature ranges, housing materials, and locking mechanisms.

Compliance certifications remain equivalent, with both parts meeting RoHS requirements and maintaining EAR99 export classification. The substitute part includes additional features such as salt water resistance and feed-through capability, which do not conflict with standard B16 PG21 connector applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1412857 directly replace 1673740 in existing installations?

A: Yes. Both parts share identical connector type (Base - Box Mount), style (Side Entry), size (B16), thread size (PG21), and locking configuration (Locking Clip on Base Bottom). Dimensional variations (1673740: 117.00 x 57.00 x 67.00mm; 1412857: 117.50 x 57.00 x 68.00mm) fall within acceptable tolerance ranges for this form factor and do not affect mechanical fit or electrical performance.

Q: What is the difference in ingress protection between these parts?

A: The 1673740 provides IP65 protection (dust tight, water resistant). The 1412857 provides IP66/IP67/IP69K protection (dust tight, water resistant, waterproof). The enhanced rating of the substitute part represents improved environmental sealing without reducing compatibility with existing connector interfaces.

Q: Are there any compliance or certification differences?

A: Both parts maintain RoHS compliance and identical ECCN/HTSUS classifications. The 1673740 carries ROHS3 designation while the 1412857 carries RoHS designation. Both parts have Moisture Sensitivity Level 1 (Unlimited) and are suitable for equivalent applications.

Q: Why is the original part obsolete?

A: The 1673740 has been superseded by the 1412857 within the HEAVYCON® product line evolution (B series to EVO series). The substitute part provides enhanced environmental protection and additional features while maintaining full backward compatibility with existing B16 PG21 connector systems.

Q: Are there packaging differences between these parts?

A: The 1673740 is supplied with standard packaging. The 1412857 is supplied in Bulk packaging. Both parts are available in new original condition with documented inventory levels.
