Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1620455 is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle housing for female sockets with 8 positions
• Shell Size: M17-8 insert size maintains mechanical and electrical compatibility
• Mounting Configuration: Panel mount with right-angle orientation and flange mounting feature
• Contact Interface: Crimp termination for wire attachment
• Ingress Protection: IP67 minimum rating for environmental sealing
• Operating Temperature Range: Must support the application's thermal requirements
• Regulatory Compliance: RoHS compliance status for environmental and safety standards

The substitute part 1628526 satisfies these core substitution criteria while offering an active product status and enhanced specifications in certain areas.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1628526 is the manufacturer-recommended substitute for the obsolete 1620455. Both parts maintain identical core specifications for connector type, position count, shell size, mounting configuration, and contact interface.

The 1628526 offers the advantage of active product status, ensuring ongoing availability and supply chain support. It meets ROHS3 compliance, representing current regulatory standards. The enhanced ingress protection rating of IP67/IP68 provides equivalent or superior environmental sealing.

Design considerations for substitution:

• Temperature Range: The 1628526 operates to 105°C maximum, compared to 125°C for the 1620455. Applications requiring operation above 105°C require alternative solutions.
• Shielding Difference: The 1620455 is shielded; the 1628526 is unshielded. Applications requiring electromagnetic shielding must evaluate this difference against circuit requirements.
• Fastening Type: The 1620455 uses push-twist fastening; the 1628526 uses threaded fastening. Mechanical interface compatibility with mating connectors must be confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 1628526 directly replace the 1620455 in existing designs?

A: The 1628526 maintains mechanical and electrical compatibility for the core connector interface (8-position M17-8 receptacle, panel mount, right angle, crimp contacts). However, three differences require evaluation: maximum operating temperature (105°C vs. 125°C), shielding configuration (unshielded vs. shielded), and fastening mechanism (threaded vs. push-twist). Confirm these parameters against your application requirements before substitution.

Q: What is the significance of the M17-8 shell size designation?

A: M17-8 specifies the circular connector shell size and position count per IEC 61076-2-109 standards. This designation ensures mechanical and electrical compatibility between mating connectors. Both the 1620455 and 1628526 use M17-8, guaranteeing proper mating with corresponding plug connectors.

Q: Are there differences in ingress protection between these parts?

A: The 1620455 provides IP67 protection (dust tight, waterproof to 1 meter depth). The 1628526 provides IP67/IP68 protection, offering enhanced waterproof capability to greater depths. Both meet or exceed IP67 requirements for standard environmental sealing applications.

Q: What does the change from push-twist to threaded fastening mean for installation?

A: The 1620455 uses a push-twist locking mechanism; the 1628526 uses threaded fastening. These represent different mechanical connection methods with mating connectors. Verify that your mating connector supports threaded fastening before substitution.

Q: Why is the 1620455 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 1628526, as the active replacement, represents the current product offering from Phoenix Contact for this connector category and should be specified for new designs and ongoing procurement.
