Phoenix Contact 1620457 Circular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1620457 is a 17-position circular connector receptacle housing designed for panel mount, right-angle applications with a rotatable backshell. This component features a shielded metal housing with IP67 ingress protection and operates across a temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1628522 qualifies as a substitute for the 1620457 based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle housing for female sockets
• Number of positions: 17
• Shell size: M17-17
• Mounting configuration: Panel mount, right angle with flange
• Termination method: Crimp
• Orientation: Normal (N)
• Ingress protection: IP67/IP68 (meets or exceeds original specification)
• Primary material: Metal construction
• Housing color: Silver
• Compliance: ROHS3 compliant, EAR99 classification

Functional Equivalence: Both connectors serve identical mechanical and electrical interface roles within 17-position circular connector applications. The 1628522 maintains compatibility with M17-17 insert specifications and panel-mount configurations required by the original design.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1628522 is the designated manufacturer substitute for the obsolete 1620457 model. Selection of the 1628522 is supported by:

Product Status Consideration: The 1620457 is classified as obsolete, whereas the 1628522 maintains active production status. This ensures long-term availability and supply chain continuity for new designs and system replacements.

Compliance and Certification: Both components meet ROHS3 compliance requirements and carry EAR99 export classification. The 1628522 maintains equivalent environmental protection ratings (IP67/IP68) suitable for sealed enclosure applications.

Mechanical and Electrical Compatibility: The 1628522 preserves the critical interface specifications: 17-position M17-17 insert configuration, panel-mount right-angle geometry, and crimp termination method. These parameters ensure direct mechanical fit and electrical interface compatibility within existing connector systems.

Design Considerations: The 1628522 incorporates a threaded fastening mechanism compared to the push-twist design of the original. The substitute features an unshielded housing versus the shielded design of the 1620457. The maximum operating temperature of the 1628522 is 105°C, compared to 125°C for the original. These differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1628522 directly replace the 1620457 in existing installations?

A: The 1628522 maintains mechanical and electrical interface compatibility through identical 17-position M17-17 insert specifications and panel-mount right-angle configuration. However, differences in fastening type (threaded versus push-twist), shielding characteristics (unshielded versus shielded), and maximum operating temperature (105°C versus 125°C) must be evaluated for specific application requirements.

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

A: The primary differences are: (1) fastening mechanism—1620457 uses push-twist, 1628522 uses threaded fastening; (2) shielding—1620457 is shielded, 1628522 is unshielded; (3) operating temperature range—1620457 operates to 125°C, 1628522 to 105°C; (4) product status—1620457 is obsolete, 1628522 is active production.

Q: Are the electrical ratings specified for both connectors?

A: The 1620457 does not include published current or voltage ratings in the available documentation. The 1628522 is rated for 3.6A at 60V. Application-specific electrical requirements should be verified against actual circuit demands.

Q: What is the significance of the shielding difference?

A: The 1620457 features a shielded housing, while the 1628522 is unshielded. Shielding provides electromagnetic interference (EMI) protection. Applications requiring EMI suppression must account for this design difference when implementing the substitute.

Q: How do the fastening mechanisms differ?

A: The 1620457 uses a push-twist fastening system for quick-connect applications. The 1628522 employs threaded fastening, which provides a more secure mechanical lock. Installation procedures and mating cycle requirements differ between these fastening types.

Q: Is the 1628522 available in the same packaging as the 1620457?

A: The 1628522 is supplied in bulk packaging. Original packaging specifications for the 1620457 are not documented. Packaging requirements for procurement and inventory management should be confirmed with the supplier.
