Phoenix Contact 1645707 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1645707 is a heavy-duty base connector for box mount applications with side entry configuration, M40 thread size, and B16 connector size. 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 functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in industrial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1645707 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration to maintain mechanical compatibility with existing enclosure mounting points
• Size Designation: B16 size requirement ensures pin count and contact spacing compatibility
• Thread Size: M40 thread specification is mandatory for proper panel or enclosure mounting
• Operating Temperature Range: Must support -40°C to 125°C minimum to function in equivalent thermal environments
• Housing Material & Construction: Aluminum die-cast housing maintains structural and thermal characteristics
• Ingress Protection: IP65 or higher rating ensures equivalent or superior environmental sealing

The Phoenix Contact 1082591 qualifies as a substitute based on these parameters. While it offers enhanced IP66/IP67 protection and dual side entry capability, it maintains all core mechanical and electrical compatibility requirements with the original 1645707.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082591 is the qualified substitute for the obsolete 1645707 based on the following engineering criteria:

Product Status & Availability: The 1645707 is obsolete, while the 1082591 is active and currently in production. This ensures long-term component availability and supply chain continuity.

Compliance & Certification: Both parts maintain RoHS compliance. The 1082591 achieves ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for industrial applications.

Mechanical Compatibility: Identical B16 size, M40 thread, and aluminum die-cast construction ensure direct mechanical substitution in existing enclosure mounting configurations. Dimensional variance is negligible (less than 1mm across all axes).

Environmental Protection: The 1082591 provides IP66/IP67 protection, exceeding the original IP65 specification. This enhancement offers superior dust and water resistance without compromising compatibility.

Thermal Performance: Both connectors operate across the identical -40°C to 125°C temperature range, ensuring equivalent thermal performance in industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1082591 directly replace the 1645707 in existing installations?

A: Yes. Both connectors share identical B16 size, M40 thread specification, and aluminum die-cast housing. Mechanical mounting and electrical interface compatibility are maintained. The 1082591's enhanced IP66/IP67 protection provides superior environmental sealing without requiring system modifications.

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

A: The 1082591 features dual side entry capability and IP66/IP67 ingress protection compared to the single side entry and IP65 rating of the 1645707. Both maintain identical operating temperature ranges and core mechanical specifications.

Q: Why is the 1645707 listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions based on market demand and product line consolidation. The 1082591 represents the current active equivalent within the HEAVYCON® B series.

Q: Are there any packaging differences between these parts?

A: The 1645707 packaging information is not specified in available documentation. The 1082591 is supplied in bulk packaging. Confirm packaging requirements with your supplier for procurement purposes.

Q: Does the 1082591's higher IP rating affect compatibility?

A: No. IP66/IP67 protection is a performance enhancement that does not compromise compatibility. The substitute provides equal or superior environmental sealing for all applications requiring IP65 or lower protection levels.

Q: What certifications should I verify before substitution?

A: Confirm RoHS3 compliance and REACH status alignment with your application requirements. Both certifications are met by the 1082591, ensuring regulatory compliance in current industrial markets.
