Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1771998 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Designation: Must be B24 to ensure mechanical and electrical compatibility
• Thread Size: Must be PG21 for proper enclosure mounting
• Operating Temperature: Must support -40°C to 125°C range
• Housing Material: Aluminum die cast construction
• Lock Mechanism: Locking Clip (1) on Base Bottom

The substitute part 1412879 meets all these core requirements while offering enhanced ingress protection and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412879 is a direct functional substitute for the obsolete 1771998. Both components share identical mechanical mounting specifications (B24 size, PG21 thread, side entry configuration) and thermal operating range (-40°C to 125°C).

The 1412879 offers enhanced ingress protection (IP66/IP67/IP69K versus IP65) and maintains current product status with active availability. The component meets ROHS3 compliance and includes salt water resistance features. Dimensional variance is minimal (68.00mm height versus 67.00mm), presenting no installation conflicts in standard enclosure applications.

Selection of the 1412879 is appropriate for new installations and replacement scenarios where the enhanced protection rating does not conflict with system specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1412879 directly replace the 1771998 in existing installations?

A: Yes. Both components share identical connector type, size (B24), thread size (PG21), mounting style (side entry), and operating temperature range. The 1412879 provides equivalent or superior functionality with enhanced ingress protection.

Q: What is the difference in ingress protection between these parts?

A: The 1771998 provides IP65 protection (dust tight, water resistant). The 1412879 provides IP66/IP67/IP69K protection (dust tight, water resistant, waterproof). The enhanced rating does not create incompatibility; it represents improved environmental sealing.

Q: Are there dimensional compatibility concerns?

A: Height differs by 1.00mm (1771998: 67.00mm; 1412879: 68.00mm). This variance is negligible for standard enclosure mounting and does not affect functional compatibility.

Q: What is the compliance status difference?

A: The 1771998 is RoHS Compliant. The 1412879 is ROHS3 Compliant, representing current regulatory alignment. Both meet applicable environmental standards.

Q: Why is the 1771998 listed as obsolete?

A: The 1771998 belongs to the HEAVYCON® B series, which has been superseded by the HEAVYCON® EVO series (represented by 1412879). The newer series provides enhanced protection ratings and current manufacturing support.
