Phoenix Contact 1645697 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1645697 is a heavy duty connector base designed for box mount, side entry applications with M40 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 part is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1645697 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B16 to ensure mechanical and electrical compatibility
• Thread Size: M40 thread is mandatory for proper installation
• Housing Material & Construction: Aluminum die cast housing maintains structural and thermal characteristics
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Ingress Protection: Must meet or exceed IP65 rating for environmental sealing

The substitute part 1082591 qualifies as an equivalent because it maintains all critical mechanical and electrical parameters while offering enhanced ingress protection (IP66/IP67) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082591 is the qualified substitute for the obsolete 1645697 based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical B16 size designation, M40 thread specification, and aluminum die cast housing construction. Dimensional variance is negligible (less than 1mm across all axes), ensuring direct mechanical interchangeability in box mount applications.

Environmental Performance: The substitute provides enhanced ingress protection at IP66/IP67 versus the original IP65 rating. This represents a performance upgrade with no compatibility compromise, as higher IP ratings maintain backward compatibility with IP65 specifications.

Thermal & Compliance: Operating temperature range remains constant at -40°C to 125°C. The substitute achieves ROHS3 compliance versus RoHS compliance on the original, meeting current regulatory requirements.

Product Lifecycle: The substitute's active product status ensures ongoing availability, technical support, and supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1082591 directly replace 1645697 in existing installations?

A: Yes. Both parts maintain identical mechanical interfaces (B16 size, M40 thread), housing material (aluminum die cast), and operating temperature range (-40°C to 125°C). Dimensional differences are less than 1mm and do not affect mounting or performance.

Q: What is the difference between IP65 and IP66/IP67 ratings?

A: IP65 provides dust tight and water resistant protection. IP66/IP67 extends this to include waterproof capability under temporary immersion (IP67). The substitute's higher rating ensures equivalent or superior environmental sealing in all applications where the original part was specified.

Q: Are there any electrical parameter differences between these parts?

A: The provided specifications do not include electrical parameters (contact rating, voltage, current capacity). Electrical compatibility must be verified against the complete connector assembly specifications for your application.

Q: Does the "Dual" designation in the substitute part affect compatibility?

A: The "Dual" designation refers to the connector's internal configuration capability. This does not affect the base housing mechanical interface or mounting characteristics. Compatibility is maintained for box mount, side entry applications.

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

A: ROHS3 represents current regulatory compliance for restricted hazardous substances in electrical and electronic equipment. The substitute meets modern environmental and safety standards, whereas the original part carries legacy RoHS certification.

Q: Is the substitute part currently in stock?

A: According to available inventory data, Phoenix Contact 1082591 has 777 pieces in new original stock, ensuring immediate availability for procurement and deployment.
