Key Parameters

Substitute Part Grouping Explanation

Substitution of heavy duty connector hoods is determined by the following critical parameters:

Connector Type & Style: Both the main part and substitute maintain hood-coupling configuration with bottom entry design, ensuring mechanical compatibility with existing cable assemblies.

Ingress Protection Rating: Both parts provide IP65 protection (dust tight, water resistant), maintaining environmental sealing requirements.

Housing Material & Construction: Both utilize aluminum die-cast housing with powder coating, ensuring equivalent mechanical durability and environmental resistance.

Lock Mechanism: Both feature locking clip on hood top, providing identical securing methodology.

Compliance & Certifications: Both parts are RoHS compliant and REACH unaffected, meeting regulatory requirements.

Thread Interface: The main part uses M25 thread while the substitute uses PG21 thread. These represent different thread standards for the same functional purpose of securing the hood to the connector body. Thread size substitution is permissible when the connector body accommodates the alternative thread standard.

Connector Size Designation: The main part specifies B6 size while the substitute specifies size 3. These represent different sizing nomenclatures across manufacturer product lines for equivalent connector classes.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1653230000 is an active product line substitute for the obsolete Phoenix Contact 1646971. Both components share identical functional specifications for connector type, ingress protection, housing construction, and compliance certifications. The substitute part maintains equivalent mechanical and environmental performance characteristics.

The primary difference lies in thread interface specification (M25 versus PG21) and connector size nomenclature (B6 versus 3). Substitution is valid when the mating connector body is designed to accept the PG21 thread standard. Verification of thread compatibility with existing connector assemblies is required prior to implementation.

The Weidmüller part offers the advantage of active product status, ensuring continued availability, technical support, and supply chain reliability compared to the obsolete Phoenix Contact part.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between the main part and substitute? A: Compatibility is established through matching connector type (hood-coupling), entry style (bottom entry), ingress protection rating (IP65), housing material (aluminum die-cast), and locking mechanism (clip on hood top). Thread size and connector size nomenclature must be verified against the mating connector body specifications.

Q: Can the Weidmüller 1653230000 directly replace the Phoenix Contact 1646971? A: Direct replacement is possible if the connector body accommodates PG21 thread instead of M25 thread. The functional performance and environmental protection are equivalent. Physical installation verification is required.

Q: What is the significance of the product status difference? A: The Phoenix Contact part is obsolete, indicating discontinued manufacturing and limited future availability. The Weidmüller part is active, ensuring ongoing production, technical documentation updates, and supply chain continuity.

Q: Are there compliance or certification differences between these parts? A: Both parts are RoHS compliant, REACH unaffected, and classified under the same HTSUS code (8538.90.8180). Regulatory compliance is equivalent.

Q: What packaging considerations apply to these parts? A: The main part is supplied in standard packaging, while the substitute is supplied in bulk packaging. Bulk packaging may affect order quantities and storage requirements.
