Key Parameters

Substitute Part Grouping Explanation

The substitute part 1654380000 qualifies as a functional equivalent based on the following critical parameters that determine substitutability:

• Connector Type & Configuration: Both parts are base-mounted, side entry connectors
• Size Rating: Both are size 4 connectors
• Thread Interface: Both use PG16 thread configuration
• Ingress Protection: Both maintain IP65 rating (dust tight, water resistant)
• Housing Material: Both utilize die-cast aluminum construction
• Lock Mechanism: Both feature locking clips (2) on base bottom
• Feed Through Capability: Both support feed through functionality
• Electrical Category: Both classified as heavy duty connectors

The primary distinction is that 1654380000 belongs to the RockStar® series (active product status) versus the RockClassic™ series (obsolete status), with minor dimensional variations within acceptable mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1654380000 is the designated substitute for the obsolete 1205200000. Selection of the substitute part is supported by:

• Active Product Status: The 1654380000 is an active product with current manufacturing support and availability (870 pcs in stock versus 852 pcs for the obsolete part)
• Regulatory Compliance: The substitute maintains REACH Unaffected status and EAR99 classification, matching the original part's compliance profile
• RoHS Compliance: The substitute part carries RoHS Compliant certification, providing enhanced environmental compliance
• Functional Equivalence: All critical electrical and mechanical parameters remain unchanged, ensuring direct substitution in existing applications
• Dimensional Compatibility: Dimensional variations (1.5mm length, 0.5mm width reduction) fall within standard mechanical tolerances for box mount applications

Frequently Asked Questions (FAQ)

Q: Can the 1654380000 directly replace the 1205200000 in existing installations?

A: Yes. Both parts share identical connector type, size rating, thread configuration, ingress protection rating, and locking mechanism. The dimensional differences are within acceptable tolerances for box mount applications.

Q: What is the primary reason for substitution?

A: The 1205200000 is obsolete. The 1654380000 is the active equivalent from Weidmüller's current product line, ensuring ongoing availability and manufacturing support.

Q: Are there compliance differences between the two parts?

A: Both parts maintain REACH Unaffected status and EAR99 classification. The substitute additionally carries RoHS Compliant certification, providing enhanced environmental compliance without affecting functional compatibility.

Q: Do the dimensional differences affect mechanical fit?

A: No. The dimensional variations (length reduced by 1.5mm, width reduced by 0.5mm, height identical) are within standard mechanical tolerances for die-cast aluminum box mount connectors and do not affect mounting or interface compatibility.

Q: What is the packaging difference?

A: The original part has no specified packaging designation, while the substitute is supplied in bulk packaging. This does not affect the connector's functional or mechanical properties.

Q: Are both parts from the same manufacturer?

A: Yes. Both are manufactured by Weidmüller. The difference is series designation: RockClassic™ (obsolete) versus RockStar® (active).
