Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1677979 with part number 1082593 is based on the following alignment of critical parameters:

Mechanical Compatibility:

• Both parts maintain identical B24 connector size classification
• Both feature side entry configuration for identical mounting orientation
• Both utilize aluminum die-cast housing construction
• Both maintain identical physical dimensions: 144.00mm L × 57.00mm W × 84.00mm H
• Both incorporate locking clip mechanism on base bottom

Electrical and Environmental Compatibility:

• Both operate across the same temperature range: -40°C to 125°C
• Both achieve ROHS3 compliance and REACH unaffected status
• Both are classified under identical HTSUS code 8538.90.8180

Key Differentiation: The substitute part 1082593 introduces enhanced specifications including dual M40 thread configuration (versus single PG29), upgraded ingress protection to IP66/IP67 (versus IP65), and active product status. These enhancements represent functional improvements while maintaining backward compatibility with the B24 form factor and mounting interface.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082593 serves as the primary substitute for the obsolete 1677979 based on maintained mechanical form factor and enhanced environmental protection specifications. Both parts share identical B24 connector sizing and aluminum die-cast construction, ensuring compatibility with existing mounting interfaces and enclosure designs.

The transition from PG29 to dual M40 thread configuration in the substitute part represents a design evolution within the HEAVYCON® B series. The upgrade from IP65 to IP66/IP67 ingress protection provides enhanced sealing capability for applications requiring waterproof operation, while maintaining full backward compatibility with the B24 mounting standard.

Both parts maintain identical operating temperature ranges (-40°C to 125°C) and regulatory compliance status (ROHS3, REACH unaffected), supporting direct substitution in existing system designs without additional qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1082593 directly replace the 1677979 in existing installations?

A: Yes. Both parts maintain identical B24 connector size, physical dimensions (144.00mm × 57.00mm × 84.00mm), and side entry mounting configuration. The substitute part's enhanced IP66/IP67 rating provides improved environmental protection while maintaining compatibility with existing enclosure designs.

Q: What is the primary difference between these two parts?

A: The 1082593 features dual M40 thread configuration and IP66/IP67 ingress protection, compared to the 1677979's single PG29 thread and IP65 rating. Both maintain identical operating temperature ranges and regulatory compliance.

Q: Why is the 1677979 listed as obsolete?

A: The 1677979 has been superseded by the 1082593 within Phoenix Contact's product portfolio. The substitute part offers enhanced specifications while maintaining the B24 form factor standard.

Q: Are there any temperature or compliance limitations when substituting?

A: No. Both parts operate identically across the -40°C to 125°C temperature range and maintain ROHS3 compliance and REACH unaffected status.

Q: What packaging options are available?

A: The 1677979 is supplied in standard packaging, while the 1082593 is available in bulk packaging configuration.
