Phoenix Contact 1620449 Circular Connector Receptacle Housing

Part Overview

The Phoenix Contact 1620449 is a 7-position (6 + PE) circular connector receptacle housing designed for panel mount, right-angle applications. This component features a rotatable backshell, metal shielded construction, and IP67 ingress protection rating. The part is classified as obsolete, making identification of suitable alternatives necessary for ongoing procurement and system maintenance. The connector utilizes crimp contact termination with a 1.0mm contact size and operates across a temperature range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1620449 is based on the following critical parameters that must remain consistent:

• Connector Type & Position Count: Both main and substitute parts must be receptacle housings with 7 positions (6 + PE configuration)
• Shell Size: M17-7 insert size must be maintained for mechanical compatibility
• Mounting Configuration: Panel mount with right-angle orientation is required
• Contact Termination: Crimp contact type ensures compatibility with existing cable assemblies
• Ingress Protection: IP67 minimum rating maintains environmental sealing requirements
• Operating Temperature Range: The substitute must support the operational envelope of the original design

The Phoenix Contact 1628510 qualifies as a substitute based on these parameters. Both connectors share identical position counts, shell sizes, mounting types, and contact termination methods. The 1628510 operates at -40°C to 105°C, which covers the lower portion of the original temperature range and is suitable for most applications within standard industrial environments.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1628510 is the designated substitute for the obsolete 1620449 based on functional equivalence across all critical mechanical and electrical parameters. The 1628510 is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary consideration for selection is the operating temperature range. The 1620449 supports -40°C to 125°C, while the 1628510 operates from -40°C to 105°C. Applications requiring sustained operation above 105°C should be evaluated against actual system thermal requirements before substitution.

The 1628510 provides enhanced ingress protection (IP67/IP68 versus IP67), which represents an improvement in environmental sealing capability. Both connectors maintain ROHS3 compliance and REACH affected status, supporting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1628510 directly replace the 1620449 in existing panel mount installations?

A: Yes. Both connectors share identical M17-7 shell sizes, 7-position configurations, panel mount right-angle mounting, and crimp contact termination. Physical and electrical compatibility is maintained for direct substitution in panel assemblies.

Q: What is the impact of the reduced operating temperature range on the 1628510?

A: The 1628510 operates from -40°C to 105°C compared to the 1620449's -40°C to 125°C range. Applications operating continuously above 105°C require thermal analysis to confirm suitability. Most industrial environments operate within the 1628510's temperature envelope.

Q: Are there differences in shielding between these connectors?

A: The 1620449 is shielded; the 1628510 is unshielded. Applications requiring electromagnetic interference mitigation should evaluate whether external shielding or alternative connector selection is necessary.

Q: What are the electrical ratings of the 1628510?

A: The 1628510 is rated for 14A at 630V, providing adequate capacity for standard industrial signal and power distribution applications.

Q: Why is the 1620449 obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The 1628510 from the PRO series represents the current production alternative, offering active support and availability.

Q: Are both connectors RoHS compliant?

A: The 1620449 is ROHS3 compliant. RoHS status for the 1628510 is not specified in available documentation and should be confirmed with the manufacturer for applications requiring RoHS certification.
