Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1645671 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Base - Box Mount configuration
• Connector size: B16
• Thread size: M32
• Housing material: Aluminum, Die Cast
• Operating temperature range: -40°C to 125°C minimum
• RoHS compliance status

Substitution Logic: The Phoenix Contact 1082590 qualifies as a substitute part because it maintains identical core mechanical and electrical specifications including connector type, size designation, thread size, housing material, and operating temperature range. Both parts are manufactured by Phoenix Contact and share the same HEAVYCON® series lineage. The 1082590 represents an active product with enhanced ingress protection (IP66/IP67 versus IP65) and dual side entry configuration, providing equivalent or superior environmental sealing while maintaining mechanical compatibility with M32 mounting interfaces.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082590 is the designated substitute for the obsolete 1645671 connector base. Selection of the 1082590 is supported by the following engineering factors:

Product Status Alignment: The 1082590 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete 1645671.

Compliance Enhancement: Both parts meet RoHS requirements. The 1082590 achieves ROHS3 compliance, representing current regulatory alignment. The 1082590 additionally maintains REACH unaffected status, providing documented compliance for European market applications.

Environmental Protection Upgrade: The 1082590 provides IP66/IP67 ingress protection versus the IP65 rating of the 1645671, delivering enhanced dust-tight and waterproof performance suitable for more demanding environmental conditions while maintaining backward compatibility with existing M32 mounting infrastructure.

Mechanical Compatibility: Dimensional variance between parts is negligible (1mm maximum across all axes), confirming direct mechanical substitution capability in existing enclosure designs. The dual side entry configuration of the 1082590 provides expanded connectivity options without compromising single-entry applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1082590 directly replace the 1645671 in existing installations?

A: Yes. Both connectors share identical B16 size designation, M32 thread size, and aluminum die-cast housing construction. Dimensional differences are within 1mm across all axes. The 1082590 maintains the same mounting interface and locking clip configuration, enabling direct mechanical substitution in existing enclosure designs.

Q: What is the primary advantage of selecting the 1082590 over the 1645671?

A: The 1082590 is an active product with current manufacturing support, whereas the 1645671 is obsolete. Additionally, the 1082590 provides enhanced IP66/IP67 ingress protection compared to the IP65 rating of the 1645671, offering superior environmental sealing for dust and water resistance applications.

Q: Are there any functional differences between single and dual side entry configurations?

A: The 1082590 features dual side entry capability, providing two connection points compared to the single entry design of the 1645671. This configuration expansion does not affect single-entry applications; the connector functions identically when only one entry point is utilized.

Q: Do both connectors support the same operating temperature range?

A: Yes. Both the 1645671 and 1082590 operate across the -40°C to 125°C temperature range, ensuring thermal compatibility in equivalent environmental conditions.

Q: What is the significance of ROHS3 compliance on the 1082590?

A: ROHS3 compliance indicates adherence to current Restriction of Hazardous Substances regulations, representing the latest regulatory standard. This status ensures the 1082590 meets contemporary environmental and safety requirements for component manufacturing and distribution.

Q: Are packaging considerations relevant to substitution?

A: The 1645671 is supplied in standard packaging, while the 1082590 is supplied in bulk packaging. Packaging format does not affect connector functionality or mechanical compatibility; selection depends on procurement quantity requirements and inventory management practices.
