Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Eaton A480305 barrier block connector is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type (Barrier Block)
• Number of circuits (5)
• Pitch specification (0.562" / 14.27mm)
• Current rating (50A)
• Voltage rating (150V)
• Wire gauge range (8-16 AWG)
• Top termination method (Screws with Captive Plate)
• Bottom termination method (Threaded, Insulated)
• Barrier configuration (2 Wall / Dual)
• Operating temperature range (-40°C ~ 105°C)
• Flammability rating (UL94 V-0)

Parts meeting all these parameters are classified as direct substitutes. Differences in product status, packaging format, or compliance certifications do not affect functional interchangeability in the application.

Parameter Comparison

Engineering Selection Recommendations

The Eaton A400305 is a direct functional substitute for the A480305. Both components are manufactured by Eaton within the Magnum® A4000 series and share identical electrical and mechanical specifications across all critical parameters.

Key Distinctions:

The A480305 is classified as obsolete, while the A400305 maintains active product status. The A400305 additionally carries ROHS3 compliance certification, whereas the A480305 is RoHS non-compliant. These differences reflect product lifecycle and regulatory evolution rather than functional capability.

For applications requiring RoHS3 compliance or long-term supply chain stability, the A400305 is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part satisfies the functional specification.

Frequently Asked Questions (FAQ)

Q: Can the A400305 replace the A480305 in existing installations?

A: Yes. The A400305 is functionally equivalent to the A480305 across all electrical and mechanical parameters. Both components feature identical circuit count, pitch, current and voltage ratings, termination methods, and operating temperature ranges. Direct substitution is supported.

Q: What is the difference between the A480305 and A400305?

A: The primary differences are product status and regulatory compliance. The A480305 is obsolete and RoHS non-compliant. The A400305 is an active product with ROHS3 compliance. Functionally, both components are identical.

Q: Does packaging format affect substitution eligibility?

A: No. The A480305 is supplied in standard packaging, while the A400305 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility. The components are functionally interchangeable.

Q: Are there any circuit or pitch variations within the Magnum® A4000 series that could be confused with these parts?

A: The Magnum® A4000 series includes multiple configurations. Substitution is valid only when all parameters match exactly: 5 circuits, 0.562" pitch, 50A rating, 150V rating, and dual-wall barrier construction. Verify part number and specification sheet before installation.

Q: What certifications apply to both parts?

A: Both the A480305 and A400305 carry UL94 V-0 flammability rating. The A400305 additionally carries ROHS3 compliance. Both are rated for -40°C to 105°C operation.
