Key Parameters

Substitute Part Grouping Explanation

The substitute part 1301470093 (Molex) qualifies as a functional equivalent based on the following critical parameters:

• Connector Designation: Both parts conform to NEMA L5-30R standard, ensuring mechanical and electrical compatibility
• Connector Type: Both are receptacles with female sockets
• Number of Positions: Both feature 3 positions
• Electrical Ratings: The substitute provides 30A at 125VAC, meeting standard L5-30R specifications
• Export Classification: Both share EAR99 classification

The primary difference lies in mounting configuration: the original part is panel mount, while the substitute is free hanging (in-line). This distinction requires evaluation based on the specific installation requirements of the target application.

Parameter Comparison

Engineering Selection Recommendations

The 1301470093 (Molex) serves as the primary substitute for the obsolete 546-0265. Selection of this alternative is supported by:

• Standards Compliance: Both parts conform to NEMA L5-30R specifications, ensuring electrical and mechanical interchangeability at the connector interface level
• Active Product Status: The Molex part is currently in active production with documented inventory availability, eliminating supply chain risk associated with the obsolete Staco component
• Regulatory Approvals: The substitute carries CSA and UL certifications, providing third-party validation for safety-critical applications
• Electrical Specifications: The 30A/125VAC rating of the substitute aligns with standard L5-30R operational parameters

The mounting configuration difference (panel mount versus free hanging) must be evaluated against specific installation geometry and mechanical constraints of the target application. This distinction does not affect electrical compatibility but requires assessment of physical integration feasibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1301470093 directly replace the Staco 546-0265 in existing installations?

A: Electrical and connector interface compatibility is assured through NEMA L5-30R standardization. Physical installation feasibility depends on the mounting configuration of the original equipment. Panel mount applications require mechanical adaptation if transitioning to a free hanging connector.

Q: What are the key parameters that define substitution eligibility for L5-30R receptacles?

A: Substitution is determined by conformance to NEMA L5-30R designation, receptacle type with female sockets, 3-position configuration, and electrical ratings of 30A/125VAC. Mounting type and termination method are secondary considerations that affect installation but not electrical compatibility.

Q: Are there compliance differences between the original and substitute parts?

A: The Molex substitute carries active CSA and UL certifications. The original Staco part specifications do not document approval agencies. For applications requiring specific regulatory compliance, the documented certifications of the Molex part provide explicit validation.

Q: What is the significance of the IP67 rating on the Molex part?

A: The IP67 ingress protection rating indicates dust-tight and waterproof performance. This specification is not documented for the original part. If the application environment requires environmental sealing, the Molex part provides this capability as an additional feature.

Q: How do packaging and inventory considerations affect part selection?

A: The Molex part is supplied in bulk packaging with active inventory status, ensuring availability for procurement. The original Staco part is obsolete, making new stock acquisition impractical for ongoing applications.
