AC Power Connector Plug 546-0264 Equivalent & Substitute Parts

Part Overview

The Staco Energy Products Company model 546-0264 is an AC power connector plug classified as NEMA L5-30P, designed for male blade free hanging (in-line) applications. This connector is used in power distribution systems requiring 30-ampere capacity at 125VAC. Substitute parts become necessary when the original manufacturer discontinues production, inventory becomes unavailable, or when equivalent connectors from alternative manufacturers meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 546-0264 is determined by strict equivalence across the following parameters:

• Connector standard: NEMA L5-30P
• Connector type: Plug with male blades
• Mounting configuration: Free hanging (in-line)
• Current rating: 30 amperes
• Voltage rating: 125VAC
• Number of positions: 3
• Termination method: Screw

The substitute part Molex 1301470073 meets all these criteria, establishing direct functional and mechanical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1301470073 serves as a direct substitute for the 546-0264 based on identical electrical ratings (30A, 125VAC) and mechanical configuration (NEMA L5-30P, male blades, free hanging, 3-position). The Molex part carries active product status and holds CSA and UL approvals, meeting standard compliance requirements for AC power connector applications. The screw termination method and IP67 ingress protection rating of the Molex substitute provide additional environmental sealing capabilities beyond the base specification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1301470073 directly replace the Staco 546-0264?

A: Yes. Both connectors conform to the NEMA L5-30P standard with identical electrical ratings (30A, 125VAC), connector type (plug, male blades), mounting configuration (free hanging), and position count (3). Mechanical and electrical compatibility is established.

Q: What is the difference in termination between these parts?

A: The Molex 1301470073 uses screw termination. The termination method for the original 546-0264 is not specified in the available data. Screw termination is standard for this connector class and provides secure wire attachment.

Q: Does the Molex substitute offer better environmental protection?

A: The Molex 1301470073 is rated IP67 (dust tight, waterproof), providing sealed operation in wet or contaminated environments. Environmental protection rating for the 546-0264 is not specified.

Q: Are both parts certified by recognized approval agencies?

A: The Molex 1301470073 holds CSA and UL approvals. Approval agency certifications for the 546-0264 are not specified in the available data.

Q: What is the packaging difference?

A: The Molex substitute is supplied in bulk packaging. Original packaging specification for the 546-0264 is not provided.
