Key Parameters

Substitute Part Grouping Explanation

Substitution for the Phoenix Contact 1662939 is based on the following critical parameters:

• Accessory Type: Both main and substitute parts must function as actuator boxes for circular connector applications
• Environmental Protection: Dust-tight and waterproof construction is required for equivalent functionality
• Manufacturer Compliance: RoHS and REACH compliance ensures regulatory alignment
• Material Compatibility: Polyamide and PBT materials provide equivalent mechanical and environmental resistance
• Connector Opening Configuration: The substitute part (1175449) provides 8 connector openings, representing an expanded capacity variant within the same product family

The Phoenix Contact 1175449 qualifies as a functional substitute based on shared environmental protection features, identical moisture sensitivity rating, and compatible material properties suitable for circular connector applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1175449 is an active product suitable for replacing the obsolete 1662939 in circular connector applications. Both parts maintain identical moisture sensitivity ratings and equivalent environmental protection specifications. The 1175449 provides expanded connector capacity (8 openings versus 4), which accommodates higher-density connector configurations while maintaining dust-tight and waterproof performance.

Material substitution from polyamide to PBT does not compromise functional equivalence, as both materials provide suitable mechanical and environmental resistance for this application category. The 1175449 maintains RoHS compliance, ensuring regulatory alignment with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the 1175449 directly replace the 1662939 in existing installations?

A: The 1175449 functions as an equivalent actuator box for circular connector applications. The primary difference is connector opening capacity (8 versus 4), which may require mechanical integration assessment based on your specific mounting configuration.

Q: What is the significance of the material change from polyamide to PBT?

A: Both polyamide and PBT provide equivalent environmental protection and mechanical durability for dust-tight, waterproof actuator box applications. Material selection does not affect functional compatibility with circular connectors.

Q: Does the color difference between parts affect compatibility?

A: Color is a cosmetic parameter and does not affect electrical or mechanical functionality. The green (1662939) and black (1175449) variants are functionally equivalent.

Q: Why is the 1662939 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Phoenix Contact. The 1175449 is an active product within the same product family and serves equivalent applications.

Q: Are both parts compliant with current regulatory standards?

A: The 1175449 maintains current RoHS compliance. The 1662939, though obsolete, is ROHS3 compliant. Both parts meet regulatory requirements for their respective manufacturing periods.
