Phoenix Contact 1677898 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1677898 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG29 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 classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1677898 is determined by the following critical parameters:

• Connector Type & Mounting: Must be Base - Box Mount configuration
• Entry Style: Must support Side Entry orientation
• Size Classification: Must be B16 size category
• Temperature Range: Must maintain -40°C to 125°C operating capability
• Housing Material & Construction: Aluminum die cast construction
• Series Compatibility: HEAVYCON® series designation

The substitute part 1082591 qualifies as an equivalent alternative based on these core parameters. While it introduces enhanced ingress protection (IP66/IP67 versus IP65) and dual M40 threading capability, it maintains full compatibility with the B16 size class, side entry configuration, and identical operating temperature specifications.

Engineering Selection Recommendations

The Phoenix Contact 1082591 serves as the active production equivalent for the obsolete 1677898. Selection between these parts should be based on the following engineering criteria:

Use 1677898 (Original): Only when legacy system documentation explicitly specifies PG29 threading and IP65 protection is the maximum requirement. Inventory availability is limited to existing stock (742 pcs).

Use 1082591 (Substitute): For new installations, system upgrades, or replacements where enhanced environmental protection is beneficial. This part offers ROHS3 compliance (versus RoHS Compliant), improved ingress protection (IP66/IP67), dual M40 threading capability, and salt water resistance. Active production status ensures long-term availability (777 pcs in stock). Both parts maintain identical operating temperature ranges and B16 size specifications, ensuring mechanical and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1082591 directly replace 1677898 in existing installations? A: Mechanical compatibility is confirmed for B16 size, side entry configuration, and identical mounting footprint. Thread size differs (M40 versus PG29), requiring verification of enclosure threading compatibility before installation.

Q: What is the difference between IP65 and IP66/IP67 ratings? A: IP65 provides dust tight and water resistant protection. IP66/IP67 adds waterproof capability, suitable for submersion or high-pressure water jet environments. Selection depends on actual environmental exposure conditions.

Q: Are both parts RoHS compliant? A: Yes. The 1677898 meets RoHS Compliant standards. The 1082591 meets the more recent ROHS3 Compliant standard, indicating compliance with updated regulatory requirements.

Q: Does the dual M40 threading on 1082591 affect compatibility? A: Dual M40 threading provides two entry points instead of single PG29. This is a functional enhancement but requires enclosure design verification to confirm thread pattern compatibility.

Q: What is the operating temperature range for both parts? A: Both 1677898 and 1082591 operate across -40°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: Is 1082591 available in the same packaging as 1677898? A: 1082591 is supplied in Bulk packaging. Packaging configuration should be verified against procurement requirements.
