Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1644630 is based on strict equivalence of the following critical parameters:

• Connector Type & Style: Hood connector with top entry configuration
• Size Designation: B16 size class
• Thread Interface: M25 thread size for mounting compatibility
• Lock Mechanism: Screw locks on hood for consistent assembly
• Ingress Protection: IP66/IP68/IP69K rating for environmental sealing
• Housing Material: Aluminum die cast construction
• Operating Temperature: -40°C to 125°C range
• Regulatory Compliance: RoHS compliant status

The substitute part 1414977 maintains all critical electrical and mechanical parameters required for direct functional replacement. Dimensional variations within the housing envelope do not affect connector interface compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1414977 directly replace the obsolete 1644630 in existing assemblies?

A: Yes. Both parts share identical connector type, size designation (B16), thread interface (M25), lock mechanism, and ingress protection rating (IP66/IP68/IP69K). The parts are mechanically and electrically compatible for direct substitution.

Q: What are the key differences between these two parts?

A: The primary difference is product status: 1644630 is obsolete while 1414977 is active. Minor dimensional variations exist in the housing envelope (1414977 is slightly smaller), but these do not affect connector interface compatibility. Part 1414977 includes salt water resistance as an additional feature.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1644630 and 1414977 are RoHS compliant and suitable for applications requiring regulatory compliance.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across the range of -40°C to 125°C, maintaining performance specifications throughout this temperature envelope.

Q: Does packaging differ between these parts?

A: The 1644630 is supplied in standard packaging, while 1414977 is available in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality.

Q: Are these connectors suitable for harsh environmental conditions?

A: Yes. Both parts provide IP66/IP68/IP69K ingress protection, qualifying them for dust-tight and waterproof applications. The 1414977 includes additional salt water resistance.
