Phoenix Contact 1646463 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1646463 is a heavy duty connector base designed for box mount, side entry applications with M32 thread size in the B10 configuration. This connector delivers IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1646463 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: B10 size classification ensures pin count and contact spacing compatibility
• Thread Size: M32 thread specification is mandatory for proper panel or enclosure penetration
• Operating Temperature: Must support the -40°C to 125°C range or equivalent
• Housing Material & Dimensions: Aluminum die cast construction with matching form factor (93.00mm L × 57.00mm W × 74.00mm H)
• Ingress Protection: Must meet or exceed IP65 rating for equivalent environmental sealing

The substitute part 1082583 satisfies all mechanical and electrical compatibility criteria while offering enhanced ingress protection and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Phoenix Contact 1082583 is the qualified substitute for 1646463. Both parts maintain identical mechanical interfaces (M32 thread, B10 size, side entry configuration, matching dimensions) and thermal operating range. The 1082583 provides enhanced ingress protection at IP66/IP67 versus the original IP65 specification, representing a functional upgrade with no compatibility compromise.

Product Status Consideration: The 1646463 is obsolete while 1082583 maintains active product status with Phoenix Contact, ensuring continued availability, technical support, and supply chain reliability for future procurement requirements.

Compliance: Both parts meet RoHS requirements. The 1082583 carries ROHS3 compliance certification, representing current regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can 1082583 directly replace 1646463 in existing installations? A: Yes. Both connectors share identical mechanical specifications (M32 thread, B10 size, side entry, 93×57×74mm form factor) and thermal range (-40°C to 125°C). The 1082583 provides enhanced IP66/IP67 sealing versus the original IP65, making it functionally compatible and superior for environmental protection.

Q: What is the difference between IP65 and IP66/IP67? A: IP65 provides dust tight and water resistant protection. IP66 adds protection against high-pressure water jets. IP67 adds temporary immersion capability. The 1082583 exceeds the original specification, offering greater environmental sealing without requiring any installation modifications.

Q: Are the physical dimensions identical? A: Yes. Both 1646463 and 1082583 measure 93.00mm length × 57.00mm width × 74.00mm height with matching M32 thread penetration and locking clip positioning on the base bottom.

Q: What does "Dual" mean in the 1082583 description? A: The 1082583 features dual M32 thread capability, providing additional configuration flexibility while maintaining the same overall form factor and mounting footprint as the original 1646463.

Q: Are there packaging differences? A: The 1646463 is listed without specified packaging, while 1082583 is supplied in bulk packaging. Both are available as new original stock from Phoenix Contact.

Q: Does the substitute part require any installation modifications? A: No. The 1082583 maintains identical mechanical interfaces, thread specifications, and mounting requirements as the 1646463, enabling direct substitution without enclosure or system modifications.
