Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1774674 is determined by the following critical parameters:

• Connector Type: Must be Female Coupler to ensure mechanical and electrical compatibility with mating components
• Wire Cross-Section Range: Must accommodate 2.5mm² ~ 6.0mm² to maintain proper contact pressure and current-carrying capacity
• Coding/Keying System: Must be compatible with the Plus system to prevent incorrect mating with incompatible connectors
• Application Category: Must be rated for photovoltaic (solar panel) applications to ensure compliance with relevant electrical and environmental standards
• Compliance Standards: Must maintain ROHS3 and REACH compliance to meet regulatory requirements

The Phoenix Contact 1386381 meets all substitution criteria as an active, manufacturer-recommended alternative.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1386381 is the manufacturer-recommended substitute for the obsolete 1774674. Both connectors share identical electrical and mechanical specifications for wire cross-section accommodation and connector type classification. The 1386381 maintains full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original component.

The primary distinction is product status: the 1386381 is currently active in the Phoenix Contact product line, providing assured availability and ongoing manufacturer support. For applications requiring the 1774674, direct substitution with the 1386381 is appropriate where connector coding and keying compatibility with existing mating components is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 1386381 directly replace the 1774674 in existing photovoltaic systems?

A: Yes, the 1386381 is the manufacturer-recommended substitute. Both connectors are female couplers with identical wire cross-section ranges (2.5mm² ~ 6.0mm²) and maintain equivalent compliance certifications. Compatibility depends on confirmation that mating connectors use the same coding/keying system.

Q: What is the significance of the Plus coding on the 1774674?

A: Plus coding is a keying system that prevents incorrect mating with incompatible connector types. The 1386381 substitute must be verified for coding compatibility with existing mated components in the installation.

Q: Why is the 1774674 classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. The 1386381 serves as the current production equivalent, ensuring continued availability for maintenance and new installations.

Q: Are there differences in packaging between these connectors?

A: Both the 1774674 and 1386381 are supplied in bulk packaging. No packaging format changes are required for substitution.

Q: Do both connectors meet current regulatory standards?

A: Yes. Both the 1774674 and 1386381 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for photovoltaic connector applications.
